    * These models exclude rapid dynamical changes in ice flow Complementarily, Figure 1 - Sea Level Rise according to SRES models shows that the global mean sea level is projected to rise by 0.09 to 0.88 meters between 1990 and 2100, for the full range of SRES scenarios

  • Small Boats Harbours Project 02000/A1 4 General Specifications Appendix 1 Shiplift Area

    Design Criteria

    Figure 1 - Sea Level Rise according to SRES models Based on these discussions and on the strategic importance of this project, a conservative estimate for the sea level rise of 0.5m will be taken.

    2.8 Storm Surge Storms are atmospheric disturbances characterized by low-pressures and strong winds. A storm surge represents the water surface response to wind-induced surface shear stress and pressure fields. Storm-induced surges can produce short-term increases in water level that rise to an eleva-tion considerably above mean water levels. The storm surge combines the effects of wind and barometric set ups. A numerical circulation model was implemented to estimate the extreme sea-level elevation by analysing the weather data including pressure and wind fields. Based on the study, the storm surge is estimated to be 0.75m with a return period of 100 years. Detailed information about the model study can be referred in the Offshore Metocean Conditions Report.

    2.9 Harbour Tranquillity As defined in KOC's Technical Specifications, the design wave height inside the protected harbour areas cannot exceed 0.30m (1 foot). In accordance with the OCDI standards, for basins that are located in front of mooring facilities and used for accommodating or mooring vessels, the calm-ness of a specified level shall be achieved for 97.5% or more of the days of the year.

    2.10 Wind Basic Wind Speed as defined by ASCE 7-05 will be set at 45m/s.

  • Small Boats Harbours Project 02000/A1 5 General Specifications Appendix 1 Shiplift Area

    Design Criteria

    2.11 Currents As defined in KOC's Technical Specifications (2), the currents inside the protected harbour areas shall not exceed 0.30m/s (1 ft/s).

    2.12 Material Properties

    Concrete grade = 40 N/mm2 b. Cover

    Minimum cover to reinforcement is 75 millimeter.

    2. Steel a. Reinforcement

    Reinforcement shall be Type 2 high yield deformed bars having tensile strength of 460 N/mm2 as per BS 4449

    b. Tubular piles Tubular piles shall be grade S355 in Accordance with BS EN 10025.

    2.13 Over Dredging As a dredger will not be able to produce a given level without tolerance for design level, 0.5 meter allowance shall be considered for over dredging.

    2.14 Serviceability Limit State Permissible concrete crack in 50 mm cover:

    Splash Zone =0.20mm Other Zones= 0.3 mm

    2.15 Rail Beam Tolerances The principle for the rail tolerances is similar to the requirements for crane rails for which compa-rable tolerances are imposed. The maximum beam differential settlement shall be limited to 1 millimeter in 1 meter. All rail beams and hoist platform are supported on pile and settlement of the piles under all load cases shall not exceed 10mm. It shall be noted that in end transfer system, the outer rails are only to provide support for the bilge blocks and taking no account of the wheel loading on the outer rails and might no need to pile sup-porting. Due lack of information related to allowable differential settlement between side rails and centre rails, these beams are supported on pile in tender design and necessity for using pile under these beams shall be finalized in detail design of rail beams. However, these tolerances are subject to the final selection of the ship lift system supplier.

    2.16 Geotechnical Properties

    A. Stratigraphy

  • Small Boats Harbours Project 02000/A1 6 General Specifications Appendix 1 Shiplift Area

    Design Criteria

    Relatively limited geotechnical information is currently available on the geotechnical conditions at the Ship Lift location. Geotechnical design of the proposed pile foundations was based on geotechnical information from boreholes No. 3 and 14, as reported in the factual geotechnical report by Gulf Inspection International Company (GIIC) (Report No. 200902 066-SOF dated January 2010). The two boreholes, which are located 60 to 75 m from the Ship Lift location, indicate that the predominant geotechnical conditions con-sisted of deep dense to very dense fine to medium grained silty sand from the seabed down to the end of the boreholes at a level ranging from -35.0 to -36.5 m CD. Standard penetration Test (SPT) blow counts recorded in the boreholes typically ranged from 38 to more than 100 blows per 300 mm penetration, which correspond to relative density rang-ing from 66 to about 100%. It should be noted that increased SPT blow counts in the bo-reholes could be the results of the presence of gravel or gravelled-size shells at the loca-tion of the SPT test and hence caution is required when interpreting this into real com-pactness of the sand. The variations of SPT blow counts and relative density with ground levels are shown in Figure 2 and Figure 3. Fine contents in the sand ranged from 10 to 24% and generally showed some increase with depth. The sand was interbedded with a 5-m thick hard clay layer at a depth of 22 m, i.e. at a level of -28 m CD, in borehole No. 14. SPT blow counts in the clay were typically higher than 50 blows per 300 mm penetration. No laboratory test data, e.g. Atterberg Limits, un-confined compressive strength, was available for the clay layer at the time of this report preparation.

    B. Design Parameters Geotechnical design parameters for the main geological units expected at the locations of the Ship Lift (dense to very dense sand and hard clay) were determined based on em-pirical correlations with the results of the SPT. These correlations were calibrated based on the results of laboratory tests, where applicable. As mentioned in Section 2.9.1, in-creased uncertainty is expected in the engineering properties of the hard clay due to the absence of laboratory test data. A summary of the main geotechnical properties related to pile design is provided in Table 2.

    A. Self weight Load

    B. Ship lift transfer load

    C. Seismic Load

    4.2 Self Weight Load The Self Weight Load is the effective weight of the structural elements of the structure Density of concrete = 24 kN/m3 Density of sea water = 10.1 kN/m2

    4.3 Ship Lift Transfer Load Following are the design loads assumed for the Tender design of End transfer and side transfer foundations; however it should be noted that these loads are subject to the final selection of the ship lift system. It should be noted that tender drawings are based on a ship lift capacity of 42 tonnes/metre. How-ever, the detail design to be developed by the Contractor shall consider a lift capacity of 50 tonnes/metre based on revised criteria.

  • Small Boats Harbours Project 02000/A1 13 General Specifications Appendix 1 Shiplift Area

    Design Criteria

    A. End Transfer In assessing the transfer system capacity account is taken of the keel block loading/support and this arises from the wheels on the centre rail and taking no account of the wheel loading on the outer rails End Transfer Cradles (ETC) is made up of one-beam keel modules at 1.6m spacing. The end of each keel beam is supported by a pair of wheels at 0.8m spacing and wheel load is 19 tons/wheel. So wheel load wheel load configuration has been considered in analysis:

    Wheels on the outer rails are to provide support for the bilge blocks which are provisioned for sta-bility and are located on the bilge rails (every other rail)

    B. Side Transfer

    For side transfer there are four wheels per rail at a rail space of 2.65m, the wheels are 1m apart. On the bilge rails (every other rail) there are four additional wheels in pairs 5m from the centre-line.

    Based loading discussed above following wheel load configuration has been considered in analy-sis:

    It shall be noted that based on vendor advice, 1.5% of above loading has been as lateral

    4.4 Seismic Loads As the structure is located in Zone 1 of UBC, the value of peak ground acceleration (of 0.075 g) is small. Therefore, it is expected that the seismic loads will not govern the design and will not be included in design load combinations.

    C. Seismic Load

    5.2 Dead Load Density of concrete = 24 kN/m2 Density of sea water = 10.25 kN/m2

    5.3 Seismic Loads As the structure is located in Zone 1 of UBC, the value of peak ground acceleration (of 0.075 g) is small. Therefore, it is expected that the seismic loads will not govern the design and will not be included in design load combinations.

    5.4 Crane Loading Following are the design loads assumed for the Tender design of jib crane foundation; however it should be noted that these loads are subject to the final selection of the jib crane supplier.
