(2) A Type 'A' ship is one
which:
-
(a) is designed to carry only liquid cargoes in
bulk;
-
(b) has a high integrity of the exposed deck with
only small access openings to cargo compartments, closed by watertight
gasketed covers of steel or equivalent material; and
-
(c) has low permeability of loaded cargo compartments.
(3) A Type 'A' ship, if
over 150 metres (492 feet) in length to which a freeboard less than
Type 'B' has been assigned, when loaded to its summer load water-line,
shall be able to withstand the flooding of any compartment or compartments,
with an assumed permeability of 0.95, consequent upon the damage assumptions
specified in paragraph (12) of
this Regulation, and shall remain afloat in a satisfactory condition
of equilibrium as specified in paragraph
(13) of this Regulation. In such a ship, the machinery space
shall be treated as a floodable compartment, but with a permeability
of 0.85.
(4) A Type 'A' ship shall
be assigned a freeboard not less than that based on Table A of Regulation 28.
