Fuel oil transfer and drain system.(燃油输送和泄放系统) There shall be four fuel oil tanks, two in each pontoon with a combined capacity of approx. 3200m3. The tanks shall be fitted with two transfer pumps with interconnecting means. 在两个PONTOON里各有两个燃油舱，每个PONTOON里的两个燃油舱组合容量约3200 立方米。配备两台燃油输送泵，交互链接。 Fuel tanks are filled from the bunkering stations on both sides. 燃油舱的注入通过平台两舷的注入站实现。 Fuel oil transfer pump capacity@delivery pressure: 60m3/hr@6bar 燃油输送泵的容量为：60m3/hr@6bar It shall be possible to drain limited amounts from day and settling tanks to the engine room slop tank, however major draining of the tanks shall be possible to the fuel oil pontoon tanks. The fuel transfer system shall be designed for 16 bar pressure. 燃油日用/沉淀舱的泄放允许一定量的燃油流入机舱溢流舱，主要的泄放还是泄放至PONTOON里的燃油舱里。燃油输送系统的设计压力为16 Bar。 702. Fuel oil purification.(燃油净化) In each engine room there shall be a fuel oil purifier w/pump. The purifier shall be fitted with a sludge tank drained to the closed drain collection tank in double bottom. Each purifier shall be fitted with a valve system enabling connection to one single day tank at a time. Capacity: 3m3 每个机舱配备一台燃油分油机，每台燃油分油机配备一个油渣舱，各油渣舱均泄放至双层底内的收集舱。每个分油机的安装要求满足同时分离单个日用舱。舱容：3 m3 703. Fuel oil supply systems. (燃油供给系统)
