ABSTRACT:
A method of installing a floatable or buoyant body on the sea floor includes towing the body to an installation site at the sea surface and subsequently submerging the body towards the sea floor by supplying ballast to the buoyant body. The supply of ballast is discontinued when the buoyant body reaches a preselected sinking velocity and the vertical movement of the buoyant body is discontinued at a predetermined level above the sea floor by a floating vessel or the like which is floating at the sea surface. One end of the vessel is connected to the buoyant body by a connector system, the length of which is smaller than the sea depth at the installation site. The buoyant body is displaced laterally to a preselected final location, whereafter the buoyant body is further submerged towards the sea floor until the same is positioned on the sea floor at a preselected installation site.
