Abstract

In drilling for an underwater source of oil and/or gas a substructure (8) is anchored on the water bed to surround the well. A tower (2) supporting a platform (1) is assembled on land from annular elements (3) and is floated out to the drilling site to be lowered onto the substructure (8) and to be anchored therewith. <IMAGE>
