Abstract

Apparatus is provided for lifting, moving, holding and controlling a load underwater. A pair of cranes (1,2) lift, move and hold the load under the control of an electro-hydraulic power and control unit (23, 24). The cranes (1, 2) have motive supports (60) and move by means of these along the sea bed to transfer the load. Buoyancy means assist in supporting the load. Each crane (1, 2) of the pair comprises an articulate gantry supporting a runway (29) and a sliding bridge (47) having a sliding trolley (77). The trolley (77) comprises lifting means (79) which lift the load, the trolley then being movable to perform minor adjustments to the position of the load, and a boom (46) for carrying tools or other means (73) for operating or acting on the load or parts for connection to the load. <IMAGE>
