摘要： PURPOSE:To prevent the adherence of marine organisms to the legs of a marine structure by a method in which the sea water is circulated in the space between the legs and a cover and an inhibitor for preventing the adherence of organisms is added to the sea water as needed. CONSTITUTION:When a pump 6 is driven, the sea water in an annular space 18 between legs 1 and a cover 5 is sucked by a pump 6 through an intake pipe 13 and a suction pipe 14, and then jetted into the space 18 through a discharge pipe 16 and a jet water pipe 15. The sea water jetted moves upwards while swirling and is again sucked from the intake pipe 13 and circulated, and on the other hand, chlorine generated in an electrolytic tank is supplied from a fixed pipe 17 into the suction pipe 14 and mixed with the sea water circulating in the space 18 to prevent the adherence of marine organisms to the legs 1.

摘要： PURPOSE:To improve thermal efficiency and fuel consumption by contact adsorbing the atmospheric air to adsorbant to remove at least a portion of nitrogen thereby feeding air having high oxygen concentration to an internal-combustion engine. CONSTITUTION:Atmospheric air sucked through a suction port 17 is fed through a filter 18, compressor 19, cooler 20, and drain separator 21 flow-in exchange valves 5, 6, 7 to adsorbing towers 1, 2, 3. The adsorbing towers 1, 2, 3 are filled with nitrogen adsorbant while flow-out exchange valves 10, 11, 12 are provided at the outlet. Said valves 5, 6, 7, 10, 11, 12 and exhaust exchange valves 14, 15, 16 provided at the downstream of the flow-in exchange valve are controlled by a controller 26 to exchange the adsorbing towers 1, 2, 3 sequentially thus to feed air having high hydrogen concentration into an internal-combustion engine 8 through a buffer tank 20.

摘要： PURPOSE:To utilize the potential cold heat of boil-off gas, by a method wherein compressed air is separated into liquid oxygen and nitrogen gas by means of boil-off gas to utilize the liquid oxygen and the nitrogen gas for combustion and seal gas, respectively. CONSTITUTION:Boil-off gas 11 generated from an LNG tank 10 is boosted by a compressor 12, and is burnt in a boiler 14 after passing through a heat exchanger 13. The open air compressed by a compressor 20 is cooled by a flushing tower 21, and a freon cooler 22, and is freed from moisture content and carbon dioxide gas by an adsorbing tower 23. The open air precooled through a heat exchanger 24 is cooled to the liquefying temperature of oxygen by the heat exchanger 13, and is separated into liquefied oxygen 25 and nitrogen gas 26. The liquefied oxygen passing through an expansion valve 28 is fed to the boiler 14 while precooling the open air through the heat exchanger 24. As noted above, the potential cold heat of boil-off gas can be utilized for separation of the compressed air into the liquefied oxygen and the nitrogen gas.
