PCT No. PCT/SE83/00145 Sec. 371 Date Dec. 15, 1983 Sec. 102(e) Date Dec. 15, 1983 PCT Filed Apr. 18, 1983 PCT Pub. No. WO83/03628 PCT Pub. Date Oct. 27, 1983.An inflatable boom raising hose is sized such that the hose, upon inflation, raises the boom from the sea bed. The hose carries internally a chain which acts as a weight to drive the hose and boom to the sea bed, which takes up tensile forces and which prevents folds being formed in the boom raising hose as it sinks to the sea bed and which insures air passage therethrough, full evacuation of the air therefrom and complete collapse of the boom raising hose during evacuation of air therefrom at one or both ends thereof when the hose is deflated. |
