Abstract

A method for relocating an object (11) standing on a first location on the seabed, comprises lifting the object off the seabed by lifting facilities in the form of strand or chain jack and winches (5) situated on a floating buoyancy body (8), to a level above the seabed for subsequent transport by submerged towing with the object (11) suspended underneath said body (8) to a second location, where the object (11) is lowered and landed onto the seabed. Means are provided for at least some load or motion compensation between the object (11) and the floating buoyancy body. At least one slender buoy (8) is used for the floating buoyancy body, the buoy preferably comprising a cylindrical section having a height at least twice its diameter. The jack winches (12) may be fitted on top of a series of vertical resilient mountings (1) made of elastic flexible materials (2) like rubber, elastomer, polyurethane or equivalent, the load-deflection curve for the resilient mountings being specified to keep the tension in the tension members (5) and the vertical movement of the object (11) with defined limitations and under proper control.
