170.185—Stability test preparations.
The following preparations must be made before conducting a stability test:
(b)
Each tank vessel must be empty and dry, except that a tank may be partially filled or full if the Coast Guard Marine Safety Center or the ABS determines that empty and dry tanks are impracticable and that the effect of filling or partial filling on the location of the center of gravity and on the displacement can be accurately determined.
(e)
Each mooring line must be arranged so that it does not interfere with the inclination of the unit during the test.
(f)
The draft and axis of rotation selected for testing a mobile offshore drilling unit must be those that result in acceptable accuracy in calculating the center of gravity and displacement of the unit.
(7)
Estimated items to be installed, removed, or relocated after the test, including the weight and location of each item.
