Abstract

1328211 Submersible dredgers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 15 Sept 1970 [17 Sept 1969] 43944/ 70 Heading E1F The propulsion means for a submersible dredger comprise hull-mounted winch systems 2 hauling on anchored cables, the winch systems being powered from electrically driven means 8 located within the hull, supplied with electrical power from a point remote from the hull, and controlled by operators within a watertight compartment of the hull. Preferably the compartment is a pressurisable, spherically-shaped chamber 16 attached to the top of the hull. The dredging means involve bladed rotary cutters 4, suction means 5 and jetting means fed with pressurised water from a pump for the ballast tanks of the hull.
