11.5.1 All lifeboats should be either of the partially
or totally enclosed type to provide adequate shelter from the anticipated
operating environment.
11.5.2 The capacity of lifeboats should be evaluated
with regard to operability, accessibility, seating capacity and overall
space, considering the needs of personnel wearing suitable polar clothing.
11.5.3 Any ice accretion should be regularly removed
from the lifeboats and launching equipment to ensure ease of launching
when required. An icing removal mallet should be available in the
vicinity of the lifeboats.
11.5.4 All lifeboat engines should be equipped
with a means to ensure they will start readily when required at the
minimum anticipated operating temperature.
11.5.5 The lifeboat engine fuel oil should be
suitable for operation in the minimum anticipated operating temperature.
11.5.6 Drinking water should be stored in containers
that allow for expansion due to freezing.
11.5.7 Consideration should be given to the provision
of additional emergency rations to account for high rates of energy
expenditure under polar conditions.
