MAN Diesel power for giant floating crane
A newly designed (DLV4400) 1748.m x 48.00 m heavy-lift floating crane from Shanghai Zhenhua Port Machinery Co Ltd (ZPMC) with a 4,400 ton lifting capacity will be powered by seven MAN Diesel 9L32/40 GenSets. The total installed output of 31.5 MW will supply propulsion power, power for maneuvering, for the crane activities, and to the hotel accommodation load for 250 persons.
The vessel, which is designed to propel itself at up to 12 knots in trial condition, will also be equipped with a dynamic positioning system classed GL DynPos--AutR. The propulsors specified are two 2,000 kW tunnel thrusters at the bow of the vessel, two 2,500 kW retractable azimuth thrusters at the foreship, and two 4,500 kW azimuth thrusters at the aftship. On the deck, the vessel will have a helicopter platform situated at the forecastle deck, and the full revolving main crane will be installed in the after area of deck. The hull for the DLV 4400 is expected to be built by a not yet disclosed Chinese yard, however, with the final outfitting and mounting of crane equipment performed at ZPMC's own shipyard at Changxin Island.
