Introduction
This document provides guidance and general information for design and field
engineering as well as owner and regulatory representatives involved in the
stability test. It contains procedures for conducting the stability test in order
to ensure that valid results are obtained with maximum precision at a minimal
cost. A complete understanding of the procedures used to perform the
stability test is imperative in order to ensure that the test is conducted properly
so that results can be examined for accuracy during the execution of the
inclining experiment.
1. Scope
1.1 The purpose of the stability test is to determine the vessels lightship characteristics. The stability test can be considered to be three separate tasks;
the certification of incline weight, the deadweight survey, and the inclining
experiment. The stability test is required upon the vessels completion or
major conversion. This test is to be completed inshore in calm weather. The
four (4) lightship characteristics determined from the stability test for
MODUs are displacement (displ), longitudinal center of gravity (LCG),
transverse center of gravity (TCG), and the vertical center of gravity (VCG,
KG).
2. Terminology
2.1 Definitions:
2.1.1 Inclining Experiment involves moving certified weights in the transverse direction, and then measuring the resulting change in
equilibrium heel angle of the vessel. Using the acquired data and
applying basic naval architecture principles, the MODUs vertical
center of gravity (VCG, KG) is determined.
2.1.2 Light Ship is the weight of the vessel with all equipment and outfit items installed. It excludes consumables, stores, cargo, crew, their
effects and liquids. Liquids included as lightship are machinery fluids,
such as lubricants, hydraulics, and cooling fluid. All machinery, fresh
water, and fire main systems are in the operating condition.

2.1.3 Lightweight Survey involves taking an audit of all the items which must be added, deducted, or relocated on the vessel at the time of the
stability test so that the observed condition can be adjusted to the
lightship condition. The weight, longitudinal, transverse, and vertical
locations of each item must be accurately determined and recorded.
The static waterline of the vessel at the time of the stability test shall
be determined by measuring the freeboard at verified draft marks. The
lightship displacement, as well as longitudinal and transverse centers
of gravity can be obtained using the previous information, the vessels
hydrostatic data, and the sea water density.
2.1.4 Slack tanks tanks that contain liquid during the stability test. The use of slack tanks should be kept to a minimum during the stability
test. Those tanks that are required to be used should comply with the
following guidelines:
(a) Full depth tanks and mud pits should be between 20% and 80% full.
(b) All other tanks should be between 40% and 60% full.
Tanks with soundings that are outside of the range described above
will be assumed to have zero free surface effect. Assuming a zero free
surface effect negatively impacts the overall KG result.
3. Significance and Use
3.1 From the lightship characteristics one is able to calculate the stability characteristics of the vessel for all conditions of loading, and thereby
determine whether the vessel satisfies the applicable stability criteria. Results
from the stability test may in some cases determine the future survival of the
vessel and its crew, so the accuracy with which the test is conducted cannot
be overemphasized. The condition of the vessel and the environment during
the test is rarely ideal and consequently, the stability test is infrequently
conducted exactly as planned. If the vessel isnt 100% complete, the weather
isnt perfect, there is water or trash in a tank that was supposed to be clean
and dry, etc., then the Naval Architect must make immediate decisions as to
the acceptability of variances from the plan.

4. Pre-Stability Test Preparation
4.1 Three months prior
4.1.1 Strip all unused tanks starting immediately after preloading for leg-up.
4.2 One week prior
4.2.1 Meet with the barge engineer(s) to be on duty during the stability test and cover the following issues:
(a) Safety issues
(b) Test Schedule
(c) Overview of the test
(d) Variable load allowance.
(e) Determine the anticipated liquid loading for the test. Preferably, all tanks should be empty. Number of slack tanks
shall be kept to a minimum and be maintained in accordance
with 2.1.4.
4.2.2 Walk the rig and make preliminary preparations. Conducted by Cameron personnel and the Barge Engineer(s).
4.2.3 Ten (10) freeboard reference marks are to be punched or painted on the hull prior to the incline. Punch mark locations, height (above
molded baseline) and distance (aft of bow) are to be verified and
recorded on Form D-13. See drawing 244-145-01 R0 for details of the
markings.
4.2.4 A preliminary audit of weights to add, deduct, and transfer in the quarters, mezzanine, and machinery deck levels shall be conducted.
4.2.5 Removal of mud from the top of the spud cans should be started as soon as possible. Open the spud can covers to allow free flooding of
the spud cans.
4.2.6 Verification of equipment operation and supplies for the test should be undertaken.
4.2.7 Regulatory bodies shall be notified of the test date and time.
4.3 Three days prior
4.3.1 Prepare for weight certification of inclining weights.

PAGE 4
4.3.2 Verify that the inclining weights are located and the operators are prepared to make the appropriate shifts. A total of 20 weights
weighting about 10 MT each shall be transferred transversely across
the unit in the vicinity of Frame 16.
4.3.3 Start preliminary set-up of incline experiment equipment.
4.3.4 Take a complete audit of drill package variable load.
4.4 Two days prior
4.4.1 Provide assistance in the weighing of the inclining weight (drill package). (Reference Section 5)
4.4.2 An audit and weighing of main deck variable to be on board during the test shall be conducted.
4.5 One day prior
4.5.1 Record the tank soundings and densities of liquid variable.
4.5.2 A tank inspection with regulatory representative shall be conducted.
4.5.3 Remove construction equipment, trash, and unnecessary cargo.
5. Test Weights
5.1 Like a ship-shaped vessel, this unit will heel under the influence of a known transverse moment shift during the stability test. A certifying authority will
individually weigh the 20 test weights to be used to induce the moment shift.
These weights will be sufficient to induce at least 1 degree of heel to each
side of upright.
5.2 A crane of sufficient capacity & reach, or some other means, must be available during the stability test to shift weights on the deck in a safe
manner.
5.3 The test weights shall be on board and in place prior to the scheduled time of the stability test.

6. Deadweight Survey
6.1 Introduction
6.1.1 The deadweight survey shall be conducted immediately preceding the incline. The shipyard and ABS shall survey the unit with the assistance
of the owner. Some items in the survey may require completion after
the incline.
6.1.2 The deadweight survey is an audit of all items. The audit is to clearly identify the variable weight and its longitudinal, transverse and vertical
centers of gravity (LCG, TCG and VCG, respectively). All audited
items are to be categorized as items to add, deduct, or transfer.
6.1.3 The as surveyed condition of the vessel is the displacement and center of gravity of the vessel at the time of the stability test. It is
determined by measuring the freeboards from the predetermined punch
marks, calculating the mean draft, comparing it to the vessels
hydrostatic data, and incorporating the variable (deadweight), its
respective LCG, TCG, and VCG and the sea water density.
6.2 Scope
6.2.1 This section provides information for determining items which need to be added to the vessel (weights to add), removed from the vessel
(weights to deduct), or relocated (weights to transfer) on the vessel to
bring the vessel to the lightship condition.
6.2.2 This section also provides information on the draft measurement operation.
6.3 Equipment
6.3.1 Microcomputer This shall be used for the spreadsheet tally of audited items.
6.3.2 Water Sampler A water sampling bottle shall be used for sampling water at any depth.
6.3.3 Hydrometers Thick-walled glass tube comprising a graduated scale for determination of a liquids specific gravity.
6.3.4 Anemometer/weather vane shall record wind speeds/directions for the duration of the Lightship Survey and Inclining Experiment.
6.4 Lightship Survey
6.4.1 Preliminary audit of the vessel shall be held one week prior the scheduled test.

(a) It is recognized that the weight of some items, either on board or that are to be added, may have to be estimated. If this is
necessary, conservative estimates should be obtained using the
following rules of thumb:
When estimating weights to be added:
i. estimate high for items to be added high in the vessel.
ii. estimate low for items to be added low in the vessel.
When estimating weights to be removed:
i. estimate low for items to be removed from high in the vessel.
ii. estimate high for items to be removed from low in the vessel.
When estimating weights to be relocated:
i. estimate high for items to be relocated to a higher point.
ii. estimate low for items to be relocated to a lower point in the vessel.
6.4.2 The initial audit shall be updated periodically as items are added, removed, or relocated.
6.4.3 Verify that all hinged, swinging, or movable items such as crane(s), derrick, travelling block, and doors are secured in their stowed position
to prevent any shift during the inclination of the vessel. If these items
are not stowed in the correct locations, they must be listed as weights
to transfer. The longitudinal position of the cantilever and the
transverse position of the drill floor during the test shall be determined.
6.4.4 A record of the length of leg installed and its vertical orientation (tip of can below baseline) shall be made. The spud can tanks shall be free
flooding during the stability test. Typically this is done by fully
submerging the spud cans while leaving the top hatch open. If this
condition is not possible, the free flooding condition of the spud cans
must be verified in some other way.
6.4.5 A list of crew and effects shall be supplied for the weight survey.
6.4.6 All tanks shall be inspected and sounded if necessary just prior to floating the vessel. Initial soundings should be taken with the rig level
in about 12 feet of draft (the rig will still be partially supported on its
legs). The Naval Architect along with the Barge Engineer shall
determine appropriate guidelines for these procedures.

6.4.7 When the vessel is put into the afloat condition, the Naval Architect shall estimate the vessel draft at the plimsol marks. The preload tanks
are to be filled as the Naval Architect directs. A sample loadout (see
Appendix E) is provided for guidance.
6.4.8 Just prior to the freeboard reading operation, a walk through shall be conducted with the regulatory representatives to verify and sign off on
the audit.
6.4.9 A preliminary set of draft readings at the yoke wells shall be taken from the main deck concurrently with the freeboard readings. These
readings will be compared to a similar set of draft readings made post-
incline to verify the condition of the vessel remained stable throughout
the test. See Section 7.5.6.
6.4.10 Samples shall be taken to determine liquid densities.
6.4.11 Typical tug line arrangement shall be at the bow and stern of the vessel. The vessel shall be positioned such as to minimize current
effects when set adrift.
6.5 Freeboard Readings
6.5.1 A total of ten (10) freeboard readings shall be made. Use the following procedure for freeboard readings:
(a) One or two boats shall be used for this operation. A freeboard reader and a regulatory representative shall be in each boat for
freeboard readings.
(b) The freeboard readers shall mount the draft tubes unit to the hull. They shall loosen the thumbscrew and slide the dampening tube
vertically to align the pointer with the punch mark on the side shell.
(c) The freeboard readers shall report to the control station the elevation of the referenced punch mark.
(d) When ready the Field Engineer shall prepare the vessel for the drift condition.
(e) The Field Engineer shall notify the freeboard readers that, Lines are slack.
(f) Visually record the draft indicated and report this value to the control station. Repeat for each of the ten (10) freeboard locations.
(g) The personnel from the boats may board the vessel for inclining.

7. Inclining Procedure
7.1 Introduction
7.1.1 This procedure requires skidding known weights transversely (port and starboard) a predetermined distance, and then measuring the resulting
change in equilibrium heel angle of the vessel. These values are
applied to calculate the vessels vertical center of gravity (KG). At the
zero position, heel shall not exceed 0.5 degrees. Trim is expected to
exceed 1% of the length of the unit, but hydrostatic properties will be
calculated for the as-surveyed floating condition. The intended
condition of the unit at the zero position is shown in Appendix E,
Pages E-1 to E-6.
7.1.2 The shipyard shall conduct the test. Three (3) pendulums will be used for the inclining experiment. A fourth pendulum shall be used to
verify the weight of the drill package (see Section 8). All data recorded
from each device shall be plotted on one curve. The test shall conclude
with acceptance by the shipyard, ABS and owner representatives.
Cameron shall conduct preliminary analysis of raw data to ensure
results are acceptable. Cameron shall later develop the Stability Test
Report and submit it to ABS for approval.
7.2 Scope
7.2.1 This procedure provides general information to ensure that valid results are obtained with maximum precision for accurate
determination of the vessels KG.
7.3 Equipment
7.3.1 Pendulums The pendulum wire should be piano wire or other mono-filament material. The top connection of the pendulum shall have
unrestricted rotation about the fulcrum. Typically, a washer is used
with the internal circumference ground to an edge. The pendulum is
hung from a structural angle with a recess ground to an edge at the
point of contact between the washer and the angle. A winged plumb
bob at the end of the wire is submerged in a trough of heavy oil
(EP220 or Equivalent) to dampen pendulum oscillations. The batten
board is attached above the trough and allows for recording
deflections. Windshields shall be installed at the main deck hatches,
enclosing the pendulum wire. Pendulum lengths should be long
enough to provide at least six (6) inches of deflection to each side of
upright during the incline. A 1.08 degree inclination would thus
require pendulum lengths of 6" / tan(1.08) = 317" measured between
the fulcrum and top of batten board. Reference 244-145-02 R0 for
pendulum illustrations.
7.4 Calibration

7.4.1 Pendulums pendulum lengths shall be measured with a steel tape from the fulcrum to the top of the batten board. Zero position on the
batten board shall be calibrated to the pendulum wire, with vessel
adrift, and the drill package in the zero (0) position. No other
calibration is required for this device.

personnel with their part of the experiment, and to resolve all outstanding
issues.
Record draft data, generate draft plot, and evaluate result.
Oversee device stations, and skidding station.
Record incline data, generate incline plot, and evaluate result.
Provide regulatory representatives with preliminary results.
2.3 Barge Engineer: Maintain an appropriate level of safety at all times. Safety issues that arise
must be addressed and appropriate action taken to resolve those issues.
These may include the following:
- Manhole covers removed for tank inspection.
- Walkways or handrails removed to accommodate skidding of the drill package.
- Extra equipment onboard for inclining.
- Safe working distance from tow equipment.
Skidding of drill package during incline.
Assist engineer in charge in preparation for the incline.
Prepare the drill package for weighing and all equipment , hoses, etc. are
remove to accommodate skidding longitudinally and transverse.
Assist engineer in charge by providing equipment weights and
documentation to determine weights to add and deduct.
Remove mud from the spud cans.
Assist engineer in charge in taking specific gravity of liquids.
Assist in the tank inspection conducted with the engineer in charge and
regulatory body representatives.
Maintain tanks between 40% to 60% full to avoid pocketing and free surface
effects. All unused tanks shall be empty and stripped.
Remove any standing water from decks.
Work with the engineer in charge in performing and documenting tank
soundings before and after the stability test.
Ensure all equalizer valves are closed.
