METHOD FOR ATTACHING HARD EQUIPMENT TO A SHIPYARD PUMP

摘要

Lifting units (30) designed to work from the seabed are fixed to the ends of the hanging equipment (10) and then applied to the seabed. The lifting units lift the equipment to allow the vessel hull to pass underneath and engage in the space defined between the lifting units. The equipment is lowered onto the hull, the lifting units dismounted, and the equipment is connected to the hull of the vessel The equipment is installed on a barge before the lifting units are applied to the seabed, the equipment and the barge are separated during the lifting operation and the barge is then removed. A number of skate assemblies are fixed at the points where the lifting units press on the seabed, with surfaces guiding the hull laterally. A number of stiffeners (16A, 16B, 16C, 16D, 18A, 18B, 18C) are fixed to the equipment before lifting to form a rigid structure between the lifting units at least during the lifting and lowering of the equipment, and these stiffeners are removed to give the equipment the necessary flexibility after it has been placed on the vessel hull. Each lifting unit has a leg with a rack which is designed to press on the seabed and a device for guiding and driving the leg mounted to move on the equipment. This device includes at least one pinion engaged with the rack and a reduction motor driving the pinion to move the leg relative to the guiding and driving device. An Independent claim is also included for equipment to carry out the above process, comprising equipment to be mounted on the vessel hull; lifting units; and devices for temporarily connecting the lifting units to the equipment at each end with a gap which allows the vessel to pass between the lifting units.
