The use of manned submersibles for the burial of submarine telecommunications cable

During the past two years it has been determined that submersibles can be used for cable burying work. The submersible mounted jet system has been used to bury cable and repeaters in a variety of bottom conditions and in water depths exceeding 600 meters. The purpose of this paper is to report on cable burying operations carried out by International Hydrodynamics, on the Canadian Continental Shelf off Nova Scotia during the Summer of 1973, using the manned submersible, PISCES V. The submersible support vessel MV HUDSON HANDLER is also described.
