20 Jul Trelleborg awarded BorWin3 wind farm project contract
Sweden-based Trelleborg’s engineered products operation has been awarded a contract by the Siemens/Petrofac consortium for its first floater installation of an offshore converter platform, the BorWin3 wind farm project.
The high voltage direct current (HVDC) converter station will sit almost 130 kilometres off the German coast in the North Sea.
Siemens will supply the HVDC transmission technology, while Petrofac will be responsible for the installation of the platform.
Vincent Tan, sales and marketing manager for Trelleborg’s engineered products operation said: “BorWin3 is only the third wind farm converter project in the world to utilise floatover technology, so it is a significant project not only for Trelleborg, but the industry too.
“For the installation of the 18,500 metric tonne topside onto the substructure, we have been contracted to supply six sets of leg mating units and the same amount of deck support units.”
The company’s leg mating units (LMUs) make a floater transition possible by damping the forces created as the topside’s load is transferred to the jacket.
The LMUs, consisting of steel structures filled with elastomeric pads are designed to tape up the static and dynamic forces of the topside structure, as well as the horizontal forces due to open sea motions during installation.
The converter is designed to transmit 900MW of wind power, which equals to the annual electricity consumption of one million German households.
The fabrication of LMUs and DSUs are scheduled for delivery in 2018. The entire project is scheduled to be completed in 2019.
