be easily understood by, the crew members of the liftboat and must 

include the following:

    (1) A table of contents and general index.

    (2) A general description of the vessel, including--

    (i) Major dimensions;

    (3) Designed limits for each mode of operation, including--

    (i) Draft;

    (ii) Air gap;

    (iii) Wave height;

    (iv) Wave period;

    (v) Wind;

    (vi) Current;

    (vii) Temperatures; and

    (viii) Other environmental factors.

    (4) The heaviest loads allowable on deck.

    (5) Information on the use of any special cross-flooding fittings 

and on the location of valves that may require closure to prevent 

progressive flooding.

    (6) Guidance on preparing the vessel for heavy weather and on what 

to do when heavy weather is forecast, including when critical decisions 

or acts--such as leaving the area and heading for a harbor of safe 

refuge, or evacuating the vessel--should be accomplished.

    (7) Guidance on operating the vessel while changing mode and while 

preparing the vessel to make a move, and information on how to avoid 

structural damage from shifting loads during heavy weather.

    (8) Information on inherent operational limitations for each mode 

and on changing modes, including preloading instructions.

    (9) Guidance on the proper procedures for discovering the flooding 

of a normally buoyant leg or leg pad, precautionary information 

concerning the effects on stability of flooded legs, and what to do upon 

discovering the flooding of a normally buoyant leg or leg pad.

    (10) A description, a diagram, operating guidance for the bilge 

system, and an alternative method of dewatering.

    (11) A general arrangement diagram showing the locations of--

    (i) Watertight and weathertight compartments;

    (ii) Openings in the hull and structure;

    (iii) Vents and closures;

    (iv) Shutdowns for mechanical and electrical emergencies, and for 

emergencies affecting ventilation;

    (v) Alarms for flooding and for too-high and too-low levels;

    (12) A list of shutdown locations for emergencies and guidance on 

restarting mechanical and electrical equipment and equipment for 

ventilation after shutdowns.

    (13) A diagram of the hazardous locations (if applicable).

    (14) A diagram of the emergency-power system.

    (15) Stability information setting forth the maximum allowable 

height of the center of gravity in relation to draft data, displacement, 

and other applicable parameters unique to the design of the unit to 

determine compliance with the intact and damage stability criteria, 

under Sec. Sec.  174.250 and 174.255 of this chapter.

    (16) Curves of form as required under Sec.  170.075(a)(3) of this
