3.1 deck machinery
power-driven (including manpower) mechanical equipment installed on ship deck, such as anchoring and mooring equipment, hoisting equipment, hatch cover opening and closing equipment, survival equipment, mechanical equipment and devices which are needed in the embarking of passengers and crew and equipment for special operations
4 Environmental condition
4.1 Deck machinery shall be operated between −25 °C and +45 °C. If ambient temperature exceeds the above limitation, it shall be specified in the contract.
5 Material and construction
5.1 Steel casting
When carbon steels and carbon manganese steels for mechanical structure are connected by welding, the carbon content shall not exceed 0,23 %. For non-welding steel castings, the carbon content shall not exceed 0,40 %. If steel castings of higher carbon content need to be used in a particular case, it shall be approved by the vessel inspection department or purchaser.
