Abstract

1359829 Suction dredgers C E McKAY and G P BARKER 20 July 1971 [11 Aug 1970] 57849/73 Divided out of 1359828 Heading E1F A swell-compensating control system for the winches of the block and tackle system supporting the ladder of the dredger of Specification 1359828 comprises sounding means 188 for determining instantaneously the height of the hull of the dredger above the bottom of the water on which the hull is floating, depth signal-generating means actuated by the sounding means, angle sensing means for determining instantaneously the angle which the true horizontal makes with the nominally horizontal centre line of the hull, angle signal-generating means 189 actuated by the angle sensing means, and control means for receiving the signals and causing adjustment of the winches in accordance with the signals. The system may also cause appropriate adjustment of the mooring lines of the dredger.
