Floatover is a proven technology of installing the heavy topside of an offshore wind structure out at sea. The process involves the heavy barge ferrying the topside structure to the installation site and the mating process beginning; the barge maneuvers into position between the jacket legs and aligns the topside structure with the substructure before it ballasts, slowly connecting the topside structure onto the jacket substructure.

As the weather and sea conditions can be harsh in an offshore environment, our floatover solutions help to ensure the transportation and installation goes flawlessly, including keeping the topside structure and substructure safe during the mating process.

During the barge ballasting operation, vertical and horizontal compression will occur on our Odin LMU (Leg Mating Unit) until the topside leg cans are in contact with the jacket leg. To stabilize the mating process, sway fenders will be in action as well. Finally, decompression will occur on our Odin DSU (Deck Support Unit), and effectively transfer the topside structure’s weight from the barge to the substructure. For this, our Odin floatover hardware plays a key role in the mating process for the floatover operation.

Our Odin LMUs consists of a steel structure incorporating engineered elastomeric pads, it can be installed either in the topside structure or the substructure. They can absorb immense loads and minimizes the risk of damage created as the topside’s load is transferred to the jacket. The elastomeric pads in our Odin LMUs are designed to absorb the static and dynamic forces of the topside structure and relieves the horizontal forces generated by the sea surface movements during the floatover mating operation. After the installation is completed, the topside leg cans are welded to the substructure.

Our Odin LMUs are tailored to each individual project, with the highest engineering levels, and subjected to rigorous testing for performance guarantees. Designed and built to the highest standards, we have applied to many projects around the world, and have been proven in safety, reliability and quality.
