Floating production storage and offloading (FPSO) cabin washing system

The utility model provides an FPSO (floating production storage and offloading) cabin washing system which is characterized in that a cabin washing machine is fixed on a main deck, the cabin washing machine is connected with a cabin washing transverse main pipe through a pipeline fixing device at the end part of the cabin washing machine, a glasses flange and a cabin washing isolating valve, the pipeline fixing device is fixed with a deck fixing device through a bolt gasket, and the deck fixing device is directly welded on the main deck; the problem that due to ship deformation, impact of cabin washing water and repeated vibration of a cabin washing machine in the working process, the risk of leakage of a cabin washing pipeline flange is likely to be caused is solved. The cabin washing system is simple in structure and equipment, the maintenance-free requirement of the cabin washing pipeline in the FPSO life cycle is met, and the ship quality is improved. 本发明提供了一种FPSO洗舱系统，洗舱机固定在主甲板上，洗舱机与洗舱横向主管通过洗舱机端部管路固定装置及眼镜
