    (c) Unless expressly provided otherwise, each survival craft must be 

provided launching appliances or marine evacuation systems, except--

    (1) Those survival craft that can be boarded from a position on deck 

less than 4.5 meters (14.75 feet) above the waterline in the lightest 

seagoing condition and that have a mass of not more than 185 kilograms 

(407 pounds);

    (2) Those survival craft that can be boarded from a position on deck 

less than 4.5 meters (14.75 feet) above the waterline in the lightest 

seagoing condition and that are stowed for launching directly from the 

stowed position, under unfavorable conditions of trim of 10 degrees and 

list of 20 degrees either way;

    (3) Those survival craft that are carried in excess of the survival 

craft for 200 percent of the total number of persons on board the OSV, 

and that have a mass of not more than 185 kilograms (407 pounds);

    (4) Those survival craft carried in excess of the survival craft for 

200 percent of the total number of persons on board the OSV, and are 

stowed for launching directly from the stowed position under unfavorable 

conditions of trim of 10 degrees and list of 20 degrees either way;

    (5) Those survival craft that are provided for use in conjunction 

with a marine evacuation system, and stowed for launching directly from 

the stowed position under unfavorable conditions of trim of 10 degrees 

and list of 20 degrees either way; or

    (6) Liferafts installed on liftboats.

    (d) Each launching appliance must be arranged so that the fully 

equipped survival craft the launching appliance serves can be safely 

launched against unfavorable conditions of trim of up to 10 degrees 

either way and of list of up to 20 degrees either way,--

    (1) When the survival craft is loaded with its full complement of 

persons; and

    (2) When not more than the required operating crew is on board.

    (e) A launching appliance must not depend on any means other than 

gravity or stored mechanical power, independent of the OSV's power 

supplies, to launch the survival craft the launching appliance serves, 

in the fully loaded and equipped condition, and also in the light 

condition.

    (f) Each launching appliance's structural attachment to the OSV must 

be designed to be at least 4.5 times--

    (1) The load imparted on the attachment by the launching appliance 

and its fully loaded survival craft under the most adverse combination 

of list and trim as required under paragraph (b) of this section; and

    (2) The ultimate strength of the construction material.

    (g) Each launching appliance must be arranged so that--

    (1) All parts requiring regular maintenance by the OSV's crew are 

readily accessible and easily maintained;

    (2) The launching appliance remains effective under conditions of 

icing;

    (3) The same type of release mechanism is used for each similar 

survival craft carried on board the OSV;

    (4) The preparation and handling of each survival craft at any one 

launching station does not interfere with the prompt preparation and 

handling of any other survival craft at any other station;

    (5) The persons on board the OSV can safely and rapidly board the 

survival craft;

    (6) Each davit-launched liferaft can be boarded by its full 

complement of persons within 3 minutes from the time the instruction to 

board is given: and

    (7) During preparation and launching, the survival craft, its 

launching appliance, and the area of water into which it is to be 

launched is illuminated by lighting supplied from the emergency source 

of electrical power.

    (h) Each launching mechanism must be arranged so it may be actuated 

by one person, both from a position on the OSV's deck, and from a 

position within the survival craft. Each launching and recovery 

arrangement must allow the operator on the deck to observe the survival 

craft at all times during launching.

    (i) Means must be provided outside the machinery space to prevent 

any discharge of water onto survival craft during abandonment.
