Abstract

Stable submersion in the sea bed of structures of the type having a base platform on which a tower or scaffolding unit is superimposed, esp. for use in off-shore drilling and the prodn. and storage of oil is effected by bringing the structure as separate elements to the position of submersion, bringing the elements of one type against elements of the other type floating flat on the surface of the sea, starting the submersion of the assembly by just bringing the base platform to a slightly negative state of buoyancy, then bringing bout complete controlled submersion by progressively increasing the wt. of the other elements forming the upper part of the structure.
