Abstract

A maritime assembly having its foundation raft and tower structure constructed separately, and then joined by the engagement of spigot and socket portions. By this reduction of pressure between those portions, hydrostatic force can be used to secure the tower structure to the foundation raft. Features include the use of a semi submersible to lower the foundation raft to the seabed, and the use of sand jacks to found the raft thereon. [US3896628A]
