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.


INCLINING AGENDA


PAGE 2

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.


INCLINING AGENDA

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.


INCLINING AGENDA


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.


INCLINING AGENDA

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.


INCLINING AGENDA


PAGE 6

(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.


INCLINING AGENDA


PAGE 7

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


INCLINING AGENDA


PAGE 9

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.
