OFFSHORE JACKET HAVING INCREASED BUOYANCY

摘要

An offshore submersible jacket assembly having bouyancy means at the lower portion of the jacket support legs. Relatively short pile sleeves are attached in a cluster to a support leg by shear plates extending generally along the length of the pile sleeves, each sleeve being connected to the leg by a pair of spaced shear plates. Upper and lower transverse plates seal off the ends of the spaced shear plates, creating airtight compartments.
