ABSTRACT:
In a method of immersion of a massive part such as a hydrocarbon storage tank on the ocean floor, the storage tank is placed over the immersion site, then lowered by means of ballast floats so that the top of the tank is close to the surface of the water. The lower end of a first rigid column also fitted with ballast floats is attached to the tank and pivotally displaced from a horizontal position at the surface of the water to a totally submerged vertical position. A number of columns are attached successively in end-to-end relation and pivotally displaced until the storage tank reaches the ocean floor.
