ABSTRACT This thesis presents the articulated stinger optimization design. The goal of the study is to develop the suitable optimal stinger model under verifying the recommended practice. The three objectives are to perform the stinger optimization in terms of stinger structural design, evaluations of stinger performance under regulation and standard code design and to develop the stinger model to be primary concept selection of stinger design. This study proposes the considerations of the stinger structural arrangement and stinger design variation through the stinger structural configurations. The stinger optimization with the scoring approach is applied to find out the suitable stinger structure for the crane capacity, wave height, tensioner capacity and current velocity requirements. The stinger cross-section configurations and stinger aspect ratio are the stinger structural arrangement which is developed to design the stinger model. Additionally, the stinger design variations consisting of the length of stinger, the diameter of tubular, wave height, current velocity and material grade are considered into pipelay performance evaluation, stinger stability evaluation and fatigue life evaluation. All of the stinger structural configurations are implemented in the stinger optimization by scoring and created the stinger concept selections. The solutions of the stinger structural configurations present that the stinger structure of Type 1 comes up with the maximum of the net buoyancy and weight ratio. For the pipelay performance evaluation, only the increasing of the stinger length has an effect with stinger performance directly. However, the no. of case which the stinger could be laid mostly will be controlled by the use of tensioner. As the stinger stability is evaluated, the stinger structure of Type 1 comes up with the maximum of the tilting angle. For the fatigue life evaluation, the applied force and the joint can thickness were an important factor that controlled the stinger’s life. Finally, the stinger optimization table selections are utilized to be a general guidance of stinger design for stinger configurations with specified stinger length.

CHAPTER 1
INTRODUCTION
1.1 General
Offshore pipelines are an important tool of hydrocarbon transportation to connect subsea wellheads to platforms and offshore oil and gas production platforms to onshore facilities. Pipelines are sized to control the expected pressure and fluid flow (Miesner et al., 2006). Subsea pipelines commonly vary from 12 in. to 30 in. To balance with the pressure both inside and outside the pipeline, wall thicknesses of the pipe is varied from ¾ in. to 2 in. of steel depending on water depth. In shallow water, the most cost of pipe is concrete coating to add weight. In deeper water, the wall thickness required to resist hydrostatic pressure is frequently sufficient to provide the needed weight. The current stinger design process is iterative procedure. The designer shall consider stinger structure, pipelay performance, and free floating stability during the design simultaneously. The designer shall create a structure configuration with sufficient buoyancy to resist vertical load from pipelay. This structure must have compatibility to withstand external loads from environmental. The structure shall also provide hydrodynamic stability during installation.
1.2 Problem statements
A stinger will be designed to perform pipelay operation at a specified water depth and pipe size. A stinger structure shall be designed:
• To sustain the load generating from environment and pipelines during operation and abandonment
• To provide sufficient buoyancy generating from pipeline during operation • To possess enough stability of the stinger during installation • To provide sufficient stinger’s life during stinger’s operation
The stinger design procedure is iterative as engineers shall design the stinger to satisfy the above-mentioned above goals simultaneously. It is clearly that that a general guidance to design a stinger will reduce their effort in design process. In addition, the stinger optimization of above criteria will provide an ultimate benefit to engineer to select an appropriate stinger to fit above requirements.
1.3 Objectives
The overall objective of this study is to thoroughly understand and suitable optimal stinger model. This objective is divided into two parts:
• To perform the stinger optimization in terms of stinger structural design, evaluations of stinger performance under regulation and standard code design.
• To create the option for concept selection in stinger design.
1.4 Scope of study
• Only two Types of stinger models from stinger structural arrangements will be analyzed into stinger structural design and evaluations of stinger performance.
• Only static analysis is considered in this study.

LITERATURE REVIEW
2.1 Introduction
This chapter provided the literature review in order to develop the knowledge about stinger, pipeline and relevant standard code. The chapter was divided into three main sections. The first section gave the detail of stinger providing Types and components. The second section dealt with required standard code for this study including API RP 2A-WSD and DNV-RP-F101. The last section gave the detail of wave providing wave component, wave theory and hydrodynamic loading.
2.2 Stinger
Pipeline installation techniques have been considered to install pipeline from vessel into seabed. Principal techniques of pipeline installation have three methods namely; (1) S-lay, (2) J-lay, and (3) Reel-lay. In S-lay method, pipelines are formed as an S-curve during the pipe is laid out from the stern of barge across stinger pipe support to seawater (Figure 2.1). This method is able to install pipeline in water depths from shallow water (15 meters) to deepwater (over 1000 meters). The S-lay vessel is able to lay at the maximum of 6.5 kilometers per day of pipeline (Miesner et al., 2006). This results on fast speed pipeline installation which become main advantage of S-lay. The curvature of the upper section namely overbend is controlled by a supporting structure namely a stinger. The curvature in the lower section namely sagbend is controlled by use of tension on the vessel. The pipeline designer has to analyze the pipelay configuration to verify that correct tension capability is checked and the pipe will not be damaged or overstressed during the pipe laying. In J-lay method, the pipeline is vertically installed in J-shape (Figure 2.2). The barge ramp is much steeper than in J-lay (less than 15 degrees to the vertical), and thus there is no over-bend and need for a stinger of any length. With the simpler pipeline shape, the J-lay method is utilized in deeper water than the S-lay method (greater than 2000 meters) depended on tensioner capacity on the barge (DA, 2002). In reel-lay method, the pipeline is welded and coated at onshore by lower cost reasonable before the pipeline is loaded into reel-barge (Figure 2.3). Lay rates of reel barges are about 1.6 to 3.2 kilometers per hour (Mousselli, 1981). These rates are very fast offshore installation time. The capacity of pipe on the reel barge depends on the reel size and pipe diameter. Normally, large diameter reels are approximately 8 to 9 meters. Due to the requirement to reel the pipeline onto a small diameter drum, the permissible amount of strain limited the maximum diameter of the pipeline. For example, the outside diameter is 4-inches for 80.77 kilometers pipe length to 16-inch for 9.14 kilometers pipe length (Bai Y. and Bai Q., 2005). Stinger was a primary pipelay tool using for S-lay operation. The structure provided a support to control the stresses developed in overbend region. The tensioner contributed for a stress control in sagbend region. The stinger and tensioner should be set up to prevent the pipeline from overstressing during pipelay operation

The stinger structure was subdivided into 2 Types namely (1) fixed stinger and (2) articulated stinger. The details of each stinger Type were as follows: 2.2.1 Fixed stinger The fixed stinger was a long straight and stiff structure (Figure 2.4). This Type of stinger had its limitations on the water depth capability and vulnerability to water currents and wave-induced barge motions (Lammert et al., 1977).The maximum feasible length of a fixed stinger was about 180 meters. A longer fixed stinger tended to break frequently due to experiencing severe loads arising from water current and motions. The articulated stinger was developed to eliminate the limitation of fixed stinger (Figure 2.5) (Langner, 1969). This Type of stinger had several segments which were connected in sequence by hinge connections. The articulated stingers were able to lay pipeline in water depth greater than 305 meters based on the lay-barge performance and stinger design. 2.2.2 Articulated stinger Articulated stinger components were separated into main structures, braces, ballast tanks, hinge connections, hitch joints, drawbars, and rollers (Figure 2.6). Firstly, the main structures were the largest pipe at corner of stinger cross-section (DA, 2008e). These components withstood the environmental loads from traverse direction and resisted the reaction loads from pipelay. These main pipe structures were connectedly welded by tubular braces to be unmovable stinger frameworks. Internal forces of stinger were transferred by main structures and braces to protect over bending in main structures. For the ballast tanks, these parts located in the main structure to control radius and buoyancy of stinger. The buoyancy of stinger was adjusted by filled seawater and compressed air from water and air plant on vessel. Forth, the hinge connection was a point link between each stinger section to be articulated stinger. The strength of hinge connections must adequately rigid for internal loads transference from section to section. Hitch joint was a junction to be utilized with the total internal force transference from the articulated stinger to the stern of the barge. An equipment of this joint must strongly withstand the total internal load transference. Therefore, thick steel plates were designed to be the drawbar of singer. Lastly, rollers were a pipe support to resist vertical load of pipeline along with articulated stinger. The roller characteristics had U-shape and V-shape. The roller height was based on the lay radius and stinger configuration during pipeline installation. The buoyancy of the stinger was controlled by ballasting of the compartment of the stinger (DA, 2008c). For ballasting into stinger, the stinger could be ballasted using the seawater to achieve the required stinger orientation during the pipelay operation. On the contrary, the stinger could be de-ballasted using a compressed air to remove the seawater from the ballasted tank. With the existing ballast controlling system, the ballasting operation was controlled by ballast control room to adjust stinger radius for specific pipelay operation condition.

2.3 Barge specifications
The variations that were used in this study were collected and compared from many companies such as Subsea 7, Mcdermott, GustoMSC, Clough, NorCE and Hyundai to properly select the range of the parameters as were shown in Table 2.1 to Table 2.9.
2.4 Simplified pipelay configuration analysis method
There were two regions of pipelay to be identified; the overbend region and sagbend region. The overbend commonly extended from the tensioner on the vessel deck and down to the lift-off point at the end of the stinger. While pipelay was not being supported by the stinger, the sagbend region commonly extended from the inflection to the touch-down point (TDP) on the seabed. 2.4.1 Curvature in overbend The configuration and curvature in the overbend region were controlled by stinger (Mousselli, 1981). The result of these occurred a bending moment and strain in the pipeline. Generally, the overbend radius of curvature (including stinger) was selected that maximum bending stress in the pipe did not exceed the Specified Minimum Yield Stress (SMYS in Table 2.14). The bending strain, εoverbend, and minimum overbend radius, Roverbend, were determined from:
overbendoverbend R

Where; D = Outside steel diameter of pipe, m Roverbend= Overbend radius of curvature, m Es = Elastic modulus of steel = 207000 MPa Fy = Minimum specified yield stress of pipe, kPa DF = Design factor, usually 0.85 for static and dynamic criteria The above analysis assumed that the pipe had a uniform bending radius over the barge and stinger support. In fact, the overbend stress of pipe usually increased at supports and decreased between the supports. Actually, pipe was allowed to exceed the yield stress in the overbend, and strain criteria (since deflection could be controlled) were used in place of the limiting-stress criteria. 2.4.2 Curvature in sagbend The sagbend stress analysis is mainly done to determine the tension and stinger-length requirement for safe laying. In general, the higher the tension is, the shorter the stinger that can be used (Mousselli, 1981). The simplest model for the calculation of the relationship between tension and curvature was the natural catenary method and this method is applicable where the pipe stiffness is very small, although the boundary condition on pipe span are not satisfied. Therefore,

another approach, stiffened catenary method, is based in a small (relative) flexural rigidity, giving the pipe a shape close to a catenary (Rienstra, 1987) (Figure 2.7 and 2.8). The equation that used to formulate the solution for the pipelay problem:

2.5 Standard code for stinger structural design
API RP 2A-WSD (American Petroleum Institute, 2000) was preferred to be the recommended practice for planning, designing, and constructing fixed offshore platforms. The stinger structural design was verified in cases of simplified and unity criteria of this structural design. The simplify criteria was used as preliminary simplify criteria of structural design check during design stages in each member. For the unity criteria, this criterion was required to verify the combined loads or stresses which occured in the structural members such as combined axial compression and bending, combined axial tension and bending, and etc. 2.5.1 Preliminary simplify criteria for structural steel design The primary requirement of stinger structural design was allowable stresses to sustain stresses from loads. The axial and shear stresses should not exceed from axial and shear stress criteria.
1. Axial tension For cylindrical members, the allowable tensile stress, Ft, should be determined from:
yt FF 6.0= (7) Where; Fy = Yield strength, MPa

For members with 60>tD , Fy in determining Cc and Fa was replaced with the critical
local buckling stress (Equation 11 and 12).
• Local buckling When the value of D/t ratio was between 60 and 300 and wall thickness t > 6 mm, both the elastic (Fxe) and inelastic local buckling stress (Fxc) should be determined from Equation 11 and Equation 12. Overall column buckling should be calculated by replacing the critical local buckling stress.

Where; C = Critical elastic buckling coefficient

The C value was theoretically 0.6. But, a reduced value of C = 0.3 was proposed to determine in Equation 11.

2. Combined axial tension and bending
The combined tension and bending of cylindrical members were proportioned to satisfy Equation 22 at all point along their length, where fbx and fby were the calculated bending tensile stresses. 2.5.3 Strength of tubular joints This section concerned with tubular joint design which was formed by the connection of two or more tubular members. The strength of tubular joint considerations was presented in this section. (i.e. the yield stress for the chord in the calculation of joint was limited to 0.8 times of the tensile strength) The wall thickness at the tubular joint was adequate for environmental load resistance.
11
1. Joint classification The tubular and brace connection was classified into K, X, and Y components depending on loading (Figure 2.9). Only a component of tubular joint Types was considered in one plane. For K- joint, the axial load in the brace should be balanced within 10% by loads in other braces in the same plane and on the same side of the joint. For Y- joint, the axial load in the brace was reacted as beam shear in the chord. For X- joint, the axial load in the brace was transferred through the chord to the opposite side.
2. Joint detailing The joint detailing was an important portion of joint design and was separated into in-plane and out-of-plane joint detailing (Figure 2.10 and 2.11). If a chord wall thickness was required to increase, the tubular joint length from brace to the edge of joint was a minimum of one quarter of the chord diameter or 12 inches (300 mm), whichever was greater. If a brace wall thickness was required to increase, the brace joint length from chord to the edge of joint was a minimum of one brace diameter or 24 inches (600 mm), whichever was greater. For the clearance gap, the minimum gap between braces of in-plane and out-of-plane was 2 inches (50 mm). When the braces were overlapped, the amount of overlap was at least d/4 or 6 inches (150 mm). Where the overlapping of braces was necessary, the nominal wall thickness of this joint should be increased by more than 10% of its joint thickness.
3. Validity range The validity range for application was as follow:
0.2 ≤ β ≤ 1.0 10 ≤ γ ≤ 50 30˚ ≤ θ ≤ 90˚ Fy ≤ 72 ksi (500 MPa) g/D > -0.6 (for K-joint)

2.6 Standard code for pipelay evaluation
DNV-OS-F101 (DET NORSKE VERITAS, 2007) was the offshore standard for submarine pipeline system. This standard provided technical provisions and acceptance criteria for general use by the offshore industry as well as the technical basis for DNV offshore services. 2.6.1 Simplified laying criteria These simplified laying criteria were used as an initial simplified criterion of the local buckling checking during early design stages.
1. Overbend region There were two criterion to be satisfied the local buckling checking of overbend. Criterion I in Table 2.15 was satisfied in the determined strain for static loading which included effects of bending, axial force and local roller loads. For static added to dynamic loading, the determined strain should be satisfied with Criterion II in Table 2.15. The strain should include all effects, including varying stiffness due to field joint or buckle arrestors.
2. Sagbend region For combined static and dynamic loads, the equivalent stress in the sagbend and the stinger tip should be less than 0.87 times fy with all loads factors set to unity.

2.7 Waves
The nomenclature and definitions of symbols associated with waves was given in Figure 2.14(Barltrop N.D.P. and Adams A.J., 1991). Wave properties were described by the following:
• Period, T, was the time taken of wave crests to pass a stationary point (second). Wave frequency = 1/TZ was sometime used instead of period.
• Height, H, was the vertical distance between wave crest and wave trough.
• Surface elevation, η, was the height of the surface above mean water level (MWL).
• Water depth, d, was the depth of water from MWL to the seabed.
• Wavelength, L, was the horizontal distance between wave crests. For small

2.7.1 Significant wave height and mean zero crossing period The random nature of the ocean’s water surface could be quantified statistically. Over an interval of about 3 hours, the statistics did not very much and the sea state might be described by significant wave height (Hs) and mean zero crossing period (Tz). Some useful relationships were given in Table 2.16.
15
2.7.2 Wave theories The wave theories were derived from incompressibility and continuity, inviscidity, dynamic equilibrium and mathematic manipulation in order to predict water surface profile such as surface elevation, wavelength, particle velocity, particle acceleration and hydrostatic pressure. There were many wave theories to be capable of satisfying the various boundary conditions: linear wave theory, stokes’ wave theory, stream function wave theory, etc. These wave theories could be selected from regular wave theory selection diagram (Figure 2.15). The most commonly used of these was linear wave theory which based on the superposition of linear wave theory.
• Linear wave theory The theory was developed for 2-D plane. A potential function was of the form:

(35)
Where; Lk π2= and Tπω 2= The linear wave theory was shown in Table 2.17. For shallow and deep water, the equations in Table 2.18 might be used. 2.7.3 Hydrodynamic loading Hydrodynamic loading on offshore structures might be classified as:
a) Drag loading, vortex was generated in the flow while it was passing the members. Drag force was proportional to incident velocity squared.
b) Inertia loading, inertia force was proportional to the acceleration of the fluid.
c) Diffraction loading, a Type of inertia loading was in which the presence of the
structure modified the wave pattern and changes the loading on the structure. The computation of the force applied by waves on a cylindrical object depended on the ratio of the wavelength to the member diameter. If the wavelength to the member diameter was less than 5, the water particle motions were only locally affected by the member. The forces could be calculated from the drag and inertia components using the Morison equation. When the wavelength was greater than about 5 times of the member size, refraction effects were important.
16
• Morison’s equation Morison's equation (API RP 2A-WSD, 2000) was commonly used for the wave force calculation of drag and inertia force on marine structures as follows:

2.7.6 Rainflow counting method The time series consist of several data ranges which can be counted and presented in groups with the same data ranges. The most common counting method is rainflow counting method. The results can be given in a histogram or a diagram (Lassen, 2006). The algorithm for the rainflow counting method was given by Rychlik (1987) as follow:
1. Reduce the time history to a sequence of tensile peaks (Figure 2.16) and compressive troughs Figure (2.17).
2. Imagine that the time history is a template for a rigid sheet (pagoda roof). 3. Turn the sheet clockwise 90° (earliest time to the top). 4. Each tensile peak is imagined as a source of water that "drips" down the
pagoda. 5. Count the number of half-cycles by looking for terminations in the flow
occurring when either: 1. It reaches the end of the time history; 2. It merges with a flow that started at an earlier tensile peak; or 3. It flows opposite a tensile peak of greater magnitude. 6. Repeat step 5 for compressive troughs. 7. Assign a magnitude to each half-cycle equal to the stress difference between its
start and termination. 8. Pair up half-cycles of identical magnitude (but opposite sense) to count the
number of complete cycles. Typically, there are some residual half-cycles.

3.3 Stinger structural arrangements and stinger design variations
3.3.1 Stinger structural arrangements The stinger was designed as 4 section articulated stinger with 2 rollers per section. Two aspects of structural arrangements including stinger cross section arrangements and aspect ratio were considered in this study. The study considered 6 configurations in total including:
• Two rectangular Types of stinger cross section arrangements • Three aspect ratio for rectangular section
The details of each aspect were as follows:
1. Stinger cross-section arrangements Stinger cross-section depicted a perpendicular projection of the stinger along the stern of the barge direction. The stinger cross-section arrangements were designed to withstand its environmental load resistance and provide its stability. Two rectangular Types of the stinger cross-section were considered in this study (Figure 3.2).
2. Aspect ratio The aspect ratio of a shape is the ratio of its longer dimension to its shorter dimension (Wikipedia, 2009). It was able to be applied to two characteristic dimensions of a three-dimensional shape, such as the ratio of the longest and shortest axis, or for symmetrical objects that are described by just two measurements, such as the length and diameter of a rod. The stinger aspect ratio was applied to each stinger cross-section Types. Its stinger shape was varied in Table 3.2. These variations of stinger aspect ratio were evaluated a suitable dimension for environmental loads resistance and stability of stinger. 3.3.2 Stinger design variations The stinger design variations were also considered for each stinger structural configuration.
• Three lengths of stinger per section including 16 m, 18 m, and 20 m. • Four diameters of tubular including 42”, 46”, 52”, and 56”. • Two material grades of tubular including X52 and X60. • Five ranges of water depth including 30 m, 60 m, 90 m, 120 m, and 150 m. • Seven ranges of tensioners capacity including 100 M.T, 125 M.T, 150 M.T,

and 1 m/s. The total load combinations for this study were 100,800 cases (Table 3.3).
21
3.4 Design procedures
The design procedures were separated into two stages as follow (Figure 3.1):
• Stinger structural design: Two Types of stinger designed as shown in Figure 3.2. Variations of stinger tubular size, material grades and section length were also considered. These variations provided a variety of structural design for stinger performance evaluation.
• Evaluations of stinger performances: In the case that the designed stinger possessed the positive buoyancy, the stingers were assessed its pipelay performance, stability under free floating condition and fatigue life.
3.4.1 Stinger structural design The stinger structural was performed to verify a stinger modeling from environmental loads in accordance with API RP 2A standard. The stinger structure had to be checked the combined stress for axial stress and bending stress, tubular joint design, and buoyancy checking. The stinger design was evaluated under the environmental condition of 12 sec of wave period. The external force from the environmental condition which impacted directly with stinger structure was computed by Morrison’s equation. The articulated stinger was connected with the stern of the barge at stinger section no.1. The amount of stinger section should be increased by the stinger section no. 2, 3, and 4, when the required buoyancy was insufficient. Moreover, the stinger geometry with 2 configurations was considered to be design parameters. Structural analysis was conducted base on the static procedure to determine the adequacy of stinger section under the load combination. Static analysis was focused base on the 90 degree case which environmental loads perpendicular with the pipe direction. The loads applied on each stinger section were classified as show below. Dead loads:
• Tubular members self weight • Roller boxes and their appurtenances self weight
Live loads:
• Wave & current loads • Inertia loads and drag force
Both dead and live loads were transferred into stinger model in unit per length. The steps of stinger analysis evaluation were followed by:
1. Environmental parameter and stinger geometry were added into input parameter. 2. The origin point was set in stinger cross-section. 3. For hydrodynamic force on stinger structure, the drag force and inertia force were
calculated by Morrison’s equation. 4. The force, moment, and shear designs of bracing members and tubular were
calculated.
22
5. The structural verification was performed in each member including column buckling, shear, combined stress, and joint wall thickness.
6. The buoyancy of stinger was checked with respect to the following formula: asB WWF +≥
Where; FB = Required buoyancy Ws = Stinger structural weight
Wa = Appurtenances weight In the case that the buoyancy was the negative value, the evaluations of stinger performance was not performed in the further development. 3.4.2 Evaluations of stinger performance The stinger performance was evaluated under two considerations including pipelay performance evaluation and stinger stability evaluation. The details of assessment were as follows:
1. Pipelay performance evaluation The pipelay analysis was performed under static load cases. This analysis adopted the Stiffened Catenary’s equation to evaluate stinger performance in pipeline according to the standard code of DNV-OS-F101. Water depth and pipe size had to be taken into stinger structure calculation for evaluating the stinger’s capability. The water depth was varied in the range of 30 to 150 meter. The outside diameter of pipeline was varied from 6 to 60 in. The buoyancy requirement of stinger was not only determined but also pipelay configuration, pipelay radius, and pipelay tension were design and checked in pipelay analysis. The steps of pipelay performance analysis were followed by:
1. The information of pipe parameter, water depth, material data, stinger data, and pipe ramp configuration were required to be inputted parameter (Pipe ramp data was fixed in Table 3.4).
2. The net of force or submerged weight per unit length of pipeline, wpipe, were calculated from gravitational force (wg) and buoyancy force (Fb), as follow by:
wpipe = wg - Fb 3. To calculate allowable tension force, Tmax1, st AFDFT ⋅⋅=max was determined;
As was the cross-section area of pipeline, DF was design factor. 4. The design factors of overband and sagband were selected from Chapter 2.6.1 and
Table 2.15. 5. The minimum and maximum overbend radiuses were required to check from
Equation 2 (Rmin ≤ Rrequired ≤ Rmax). The outside diameter of pipeline was varied in this equation.
6. The span length of pipeline support was determined by Equation 5 7. The Stiffened catenary angle of pipeline was determined by Equation 4. 8. To find number of stinger section, the minimum tension of pipeline was applied at
the first section of stinger. The tension was increased by the rate with in the range of 0.01 – 1 kN until stiffened catenary angle (θcat) was equals to departing angle (θdept). The number of stinger section was counted from this acceptance criterion.
23
9. If the applied tension exceeded Tmax1 and Tmax2 (but θdep < θcat), the stinger section had to be added the increment for its departing angle.
10. This acceptance criterion was terminated from given number of section in design assumption.
11. The buoyancy requirement of pipeline had to be less than the buoyancy of stinger; otherwise, the number of stinger section had to be added and returned to check from step 8 to 10. The buoyancy requirement of pipeline was able to be found out from net force multiplied by span length.
12. Pipelay configuration, lay radius on stinger, pipelay tension, and buoyancy requirement were shown in pipelay static analysis results.
2. Stinger stability evaluation
The stinger stability was conducted as the part of the stinger cross-section arrangement in order to calculate the maximum of tilting angle to maintain the overturning stability. It was necessary to maintain the declined stinger from wave and current during installation. The stinger stability was not required in the installation process because the stinger was tightly connected by drawbar of stinger section 1 with the stern of the barge. The stinger stability was determined by metacentric height calculation at weight and buoyancy balance. At the static flotation condition, the metacentric height (GM) should be always positive. The metacentric height was the distance between the Center of Gravity and the Metacenter point illustrated in Figure 3.3 showing Center of Gravity (C.G.), Center of Buoyancy (C.B.), and Metacenter (G.M.). The steps of stinger stability were followed by:
1. The stinger geometry and relevant parameters were inputted into calculation sheet. 2. The Center of Gravity (C.G.) of the stinger was determined (point G in Figure 3.4). 3. The Center of Buoyancy (C.B.) of stinger was determined by variation of water
level. 4. The tilting angles were applied to check the stinger stability in the range of 0
degree to 40 degree which was referred to y-axis. 5. The metacentric height was calculated at stinger buoyancy and stinger weight
balance. 6. The GM line and tilting angles were plotted.
3. Fatigue life evaluation
The fatigue analysis was performed to determine the stinger’s life in accordance with DNV-RP-C203. Wave height and wave period had to be taken into fatigue analysis for evaluating the stinger’s life. The wave height was varied in range of 2 to 5 meter. The wave period was varied in range of 1 to 15 second. The steps of fatigue life analysis were followed by:
1. The wave spectrum was calculated by Equation 38. 2. The random sea surface was created by Equation 40. 3. The number of occurrence in each wave height and wave period was counted
(Table 3.5) by rainflow counting method (Orcaflex program).
24
4. Critical joint was selected by the joint that obtain more force than the other (Figure 3.5).
5. The force and moment for each wave height and wave period were calculated. 6. The predicted number of cycles to failure for stress range Δσ (N) was calculated by
Equation 41. 7. Accumulated fatigue damage, D was determined by Equation 42. 8. The fatigue life was calculated as follow:
DLife η
=
Where; Life = Fatigue life, year η = 1 / Design fatigue factor from OS-C101
D = Accumulated fatigue damage
3.5 Stinger optimization
The purpose of the stinger optimization was performed in order to obtain the optimal stinger structure for providing the sufficient buoyancy, pipelay’s capability, adequate stability for laying pipeline and stinger’s life. The stinger optimization will be evaluated by scoring. The scoring will be given as followed by: 3.5.1 The scoring for stinger structure The stinger structure was scored in the range of 0 to 1 depending on the ratio of net buoyancy and stinger weight. 3.5.2 The scoring for stinger performance evaluation
1. Pipelay performance The pipelay’s capability was scored in the range of 0 to 1 depending on the proportions of the pipelay matrix envelope.
2. Stinger stability The stability was scored in the range of 0 to 1 depending on the maximum of tilting angle.
3. Fatigue life The fatigue analysis was scored in the range of 0 to 1 depending on fatigue life of stinger. From the scoring, the stinger optimization chart was plotted to create the option for concept selection in stinger design.

CHAPTER 4
RESULTS AND DISCUSSIONS
4.1 Design results
The design results consisted of stinger structural design, pipelay performance evaluation, stinger stability evaluation and fatigue life evaluation. The calculations of the articulated stinger design were calculated on MATHCAD program. The detail results are presented in APPENDIX A. The summaries of results are presented in APPENDIX B. 4.1.1 Stinger structural design results The results obtained from stinger structural design consisting of stinger weight and net buoyancy are presented in APPENDIX B. The details of stinger structural design are presented in APPEXDIX E. The trends of stinger weight and net buoyancy are as follows (Figure C.1 to C.18):
1. Effect of Geometry (cross-sections) The design results show that Type 2 has not only less weight but also net buoyancy than Type 1. The contribution of less weight and net buoyancy are due to Type 1 has more number of brace than Type 2 by 4 to 6 members per section. Type 2 has weight and net buoyancy less than 5% and 20% to Type 1, respectively.
2. Effect of Geometry (aspect ratio) The design results show that they are a slightly different from each other because of the constant volume replacement of buoyancy. No significant difference between each other.
3. Effect of Material grade The design results show that the stinger using X60 yield better design results. The weight and net buoyancy of stinger is better than the design using X52. The stinger design with X60 has more strength than the design using X52 by 15%. The stinger using X 60 has weight less than 2.5% and has net buoyancy more than 5% to the design using X52.
4. Effect of Stinger length The design results show that the increase of weight and net buoyancy are a direct variation with stinger length. The contribution of increase is due to the increase of the volume replaceable. The different of volume replaceable between each stinger length is around 12%. The different of weight between each stinger length is around 10% and the different of net buoyancy between each stinger length is around 10% to 20%.
5. Effect of Outside diameter The design results show that the increase of weight and net buoyancy are a direct variation with outside diameter. The contribution of increase is due to the increase of the volume replaceable. The different of volume replaceable between each outside diameter is around
26
20%. The different of weight between each outside diameter is around 5% to 15% and the different of net buoyancy between each outside diameter is around 30%. 4.1.2 Pipelay performance evaluation results The results obtained from pipelay performance evaluation consisting of the tension of pipeline and no. of case which the stinger could be laid are presented in APPENDIX B. The trends of the no. of case that stinger could be laid are as follows (Table C.1 to C.2):
1. Effect of Stinger length The design results show that the increasing of no. of case that could be laid is a direct variation with stinger length. The contribution of increase is due to the increase of the volume replaceable. The different of volume replaceable between each stinger length is around 12%. The different of no. of case that could be laid between each stinger length is around 5% to 10%.
2. Effect of Tensioner capacity The design results show that the increasing of no. of case that could be laid is a direct variation with tensioner capacity. The contribution of increase is due to the higher tensioner capacity is, the higher the no. of case that could be laid. The different of capacity between each tensioner capacity is 25 ton. The different of no. of case that could be laid between each tensioner capacity is around 5% to 15%. The no. of case that could be laid mostly will be controlled by the use of tensioner (Table C.1 – C.3) but for the higher wave height and current velocity some configuration will be controlled by the buoyancy and pipeline weight. 4.1.3 Stinger stability evaluation results The results obtained from stinger stability evaluation are the maximum tilting angle are presented in APPENDIX B. The trends of the maximum tilting angle were as follows (Figure C.19):
1. Effect of Geometry (cross-sections) The design results show that the stinger cross-sections related to the increase of outside that is considered into two parts which are lower than 46 in. and higher than 52 in. The first part of tilting angle is mainly decreased. The second part of tilting angle is mainly increased. The different between each stinger cross-sections is around 20% to 50%.
2. Effect of Geometry (aspect ratio) The design results show that the specified aspect ratio is mainly increased because of the inconstant volume replacement of buoyancy. The different between each aspect ratio is around 15% to 50%.
27
3. Effect of Stinger length The design results show that the stinger length related to the increase of outside that is considered into two parts which are lower than 46 in. and higher than 52 in. The first part of tilting angle is mainly decreased. The second part of tilting angle is mainly increased. The different between each stinger length is around 10% to 50%.
4. Effect of Outside diameter The design results show that the increase of outside diameter is considered into two parts which are lower than 46 in. and higher than 52 in. The first part of tilting angle is mainly decreased. The second part of tilting angle is mainly increased. The different between each other is around 40% to 70%. 4.1.4 Fatigue life evaluation results The results obtained from fatigue life evaluation were fatigue life of the stinger as shown in APPENDIX B. As results of the fatigue life evaluation in APPENDIX C (Figure C.20 – C.28), the trends of the fatigue life were as follows:
1. Effect of Geometry (aspect ratio) The design results show that they are a slightly different from each other because of the joint that subject to wave load are the same positions. No significant difference between each other.
2. Effect of Stinger length The design results show that the increasing of fatigue life was a reverse variation with stinger length. The contribution of increase is due to the increase of wave load that applied to the structure. The different of wave load between each stinger length is around 12.5%. The different of fatigue life between each stinger length is around 30% to 50%.
3. Effect of Outside diameter The design results show that the increasing of fatigue life were a direct variation with outside diameter. The contribution of increase is due to the increase of wave load that applied to the structure. The different of wave load between each outside diameter is around 18%. The different between each outside diameter and the next to one is around 20% to 40%.

5.1 Conclusions
The articulated stinger in this study was performed in terms of stinger structural design, evaluations of stinger performance under regulation and standard code design. The structural arrangements and stinger design variations are considered into stinger structural configurations to create the stinger model. Stinger configurations are evaluated by pipelay performance, stinger stability and fatigue life. All of the stinger configurations are optimized to be primary concept selection by scoring. The conclusions from the design results of the stinger (Table 5.1) are as follows:
• In the stinger structural design, the buoyancy of stinger Type 1, aspect ratio 4:4, material grade X60, stinger length 20 m and outside diameter 56 inch are better than the other.
• In the pipelay performance evaluation, only stinger length has an effect with
pipelay performance to increase. The performance of stinger length 20 m is better than the other. However, the no. of case that the stinger could be laid mostly will be controlled by the use of tensioner.
• In the stinger stability evaluation, the stability of stinger Type 1, aspect ratio 4.5:3,
stinger length 16 m and outside diameter 42 inch are better than the other.
• In the fatigue life evaluation, the fatigue life of stinger aspect ratio 5:2.5, stinger length 16 m and outside diameter 42 inch are better than the other.
• The stinger length mostly has an influence in the stinger structural design, pipelay
performance, stinger stability and fatigue life.
• To be primary concept selection, there are 70 tables of stinger optimization depending on crane capacity, wave height and tensioner capacity.
