1 Scope
This International Standard specifies the classification, structure and main dimensions,
materials, quality of manufacture, testing of watertightness and designation for oil
tank hatches for application on board ships in order to ensure interchangeability
of the hatches. The remaining dimensions, welding, and other details are left to the
manufacturer.
These hatches generally conform to the requirements of the International Convention
on Load Lines 1966 (ILLC66). These structures and specifications of oil-tight hatch
covers in this International Standard meet IACS UR S26 requirements. The possibility
for application in position 1 and position 2 has to be considered for each situation
and, where necessary, the hatch covers shall be provided with additional stiffening.
This International Standard is applicable to the design, manufacturing, and test of
accommodation ladders, as well as accommodation ladder used specifically in combination
with pilot ladder (hereinafter referred as “pilot accommodation ladder”).
Users of this International Standard should note that while observing the requirements
of this International Standard, they should, at the same time, ensure compliance with
such statutory requirements, rules, and regulations as may be applicable to the individual
ship concerned.
