Offshore platform float-over installation is a technique used to install large topside structures onto offshore jackets or floating structures. This method is commonly used for the installation of integrated topside modules on fixed platforms, semi-submersible platforms, and FPSOs (Floating Production Storage and Offloading units). In float-over operations, the topsides of a production platform, which may vary in size from less than 1,000 tons to more than 40,000 tons, are installed from a barge. The barge is towed to the field and positioned between the legs of the supporting structure or jacket. leg mating units (lmus), deck support units, sway and surge fenders – make a valuable contribution to the float-over method of installing the topsides of offshore oil and gas platforms from a barge.
The float-over process provides a much less costly solution. But the crucial challenge, is transferring the load from the barge to the jacket. This must be done in a controlled manner without causing damage to either structure, even though waves, currents or winds are causing the barge to move. The lmus – steel structures incorporating rubber elements – make this possible by dampening the Using LMUs during a float-over process, the loads can be transferred from the barge to the base structure in a controlled manner. LMUs consist of a steel structure incorporating rubber elements to achieve a specified spring rate, depending on the expected loads and movements.
