16、ssification, 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 manu
17、facturer.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 posi
18、tion 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 combinati
19、on 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
