Abstract

The equipment is connected through a line to an auxiliary buoyant element to form an assembly of positive buoyancy, the equipment to be submerged and the auxiliary element being at first held in spaced relationship. The equipment is thereafter dropped into water, the length of the connecting line being so limited that the equipment then becomes suspended in water under the auxiliary element without reaching the water bottom. The location of the assembly is then optionally adjusted, and its buoyancy is reduced to a negative value.
