Rentel is a 309 MW offshore wind farm in the Belgian North Sea, located approximately 40 km off the coast of Ostend. The Rentel wind farm will eventually consist of 42 Siemens turbines with an individual peak capacity of 7.35 MW and will peak at a production of 309 MW.
The turbines are connected to an offshore transformer station. A 220 kV submarine cable connects this offshore substation with the onshore substation, called Stevin, in Zeebrugge. Rentel finalized its financing in October 2016, after which the construction started immediately. The head office is located in the port of Ostend, where the operational heart of the wind farm will also be located.

This operational heart has a very modern, high availability data center designed by Lasent and also realized by us. During the design phase it was already taken into account that this data center would be located at the most suitable location within the building. The electrical engineering infrastructure is also geared to this. In the room there are 3 so-called Cubes that each consist of 10 racks, a total of 30 pieces of 19” racks. The power supply is ensured by a redundant UPS configuration equipped with an emergency power generator. A facility has been installed on the outside of the building to connect a second unit. The cooling system is of course also redundant and the room is equipped with an automatic gas extinguishing system. Fire is detected at the earliest stage by a dual Aspiration detection system. To monitor everything that happens in the data center, DCIM software is used. One can rightly speak of a data center with high availability. The design uses the most energy-saving techniques and materials so that this component also optimally matches Rentel’s vision.

After the successful test and commissioning phase, Lasent also received the order for the multi-year preventive and corrective maintenance of the delivered installations.
