Sec. 108.540  Survival craft muster and embarkation arrangements.

    (a) Each muster station must have sufficient space to accommodate 
all persons assigned to muster at that station. One or more muster 
stations must be close to each embarkation station.
    (b) Each muster station and embarkation station must be readily 
accessible from accommodation and work areas.
    (c) Each lifeboat must be arranged to be boarded and launched 
directly from the stowed position.
    (d) Each lifeboat must be arranged to be boarded by its full 
complement of persons within 3 minutes from the time the instruction to 
board is given.
    (e) Each davit-launched and free-fall survival craft muster station 
and embarkation station for a survival craft which is boarded before it 
is launched must be arranged to enable stretcher cases to be placed in 
the survival craft.
    (f) Means must be provided for bringing each davit-launched survival 
craft against the side of the unit and holding it alongside to allow 
persons to be--
    (1) Safely embarked in the case of a survival craft intended to be 
boarded over the edge of the deck; and
    (2) Safely disembarked after a drill in the case of a survival craft 
not intended to be moved to the stowed position with a full complement 
of persons on board.
    (g) Each davit-launched liferaft launching arrangement must have a 
means to hold the liferaft in the embarkation position that--
    (1) Will hold the liferaft securely in high winds;
    (2) Can be rapidly engaged in the proper position for boarding; and
    (3) Can be rapidly released for launching by one person from within 
the loaded liferaft.

    (h) Each launching station or each two adjacent launching stations 
must have an embarkation ladder as follows:
    (1) Each embarkation ladder must be approved under approval series 
160.117 or be a rope ladder approved under approval series 160.017, and 
must be installed in a way that--
    (i) Each embarkation ladder must extend in a single length, from the 
deck to the waterline in the lightest seagoing condition with the unit 
listed not less than up to 15 degrees either way; or
    (ii) Each embarkation ladder may be replaced by a device approved to 
provide safe and rapid access to survival craft in the water, if the 
OCMI permits the device, provided that there is at least one embarkation 
ladder on each side of the unit.
    (2) An embarkation ladder is not required if--
    (i) The distance from the embarkation deck to the unit's lightest 
operating waterline is less than 3 meters (10 feet); and
    (ii) The unit is not in international service.
    (3) If the embarkation ladders can not be supported against a 
vertical flat surface, the unit must instead be provided with at least 
two widely separated fixed metal ladders or stairways extending from the 
deck to the surface of the water and meet the following:
    (i) Each inclined fixed ladder must meet the requirements under 
Sec. 108.159.
    (ii) Each vertical fixed ladder must meet the requirements under 
Sec. 108.160 for fixed ladders, except that the vertical bars in cages 
must be open at least 500 millimeters (20 inches) on one side throughout 
the length of the ladder.
    (iii) If a fixed ladder can not be installed, the OCMI may approve 
an alternate means of escape with sufficient capacity to permit all 
persons permitted on board to safely descend to the waterline.
    (4) Alternate means of escape under paragraphs (h)(1)(ii) and (h)(3) 
of this section, such as portable slides, safety booms, moveable 
ladders, elevators, and controlled descent devices must be approved. An 
alternate means of escape must have sufficient capacity to permit all 
persons permitted on board to safely descend to the waterline within 10 
minutes from the time the signal to start is given.
