Abstract

Ship for undersea work, for example for the laying and repair of underwater pipelines, with two cranes (2, 3) for the lowering of large objects (7), which are to be assembled or are required for carrying out work, onto the sea bed. According to the invention the cranes are so designed and arranged on the ship that together they are capable of hoisting the object (7) off the ship's deck, then taking it overboard, preferably over the stern, then lowering it outside the ship and then, by means of a rotary movement of the cranes (2, 3), of bringing the object into a position approximately below the centre of movement of the ship (1). <IMAGE>
