PREVENTER FOR ADHERENCE OF ORGANISM TO MARINE STRUCTURE

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.
