Heinen & Hopman in the Netherlands has completed the installation of a major HVAC system onboard the Dolwin Alpha offshore converter platform. Designed by IV-Oil and Gas, commissioned by Tennet/ABB and built by Heerema Fabrication group, the platform is now ready to be moved to the North Sea. This project involved the complete design and engineering of the HVAC systems, which Heinen & Hopman completed on time and to satisfaction. Heinen & Hopman received the initial order from the Heerema Fabrication group to become the HVAC subcontractor for the Dolwin Alpha project in July 2011. The Dutch company was responsible for the complete design and engineering of the heating, ventilation, air conditioning and chilled water systems, as well as the supply of all pumps, appendages, control equipment and piping on this giant offshore converter platform. Built to convert energy generated by the offshore wind turbines installed in the German North Sea into high voltage direct current, the platform weighs some 9,300 tons. The platform has now been transported to the Mammoet yard in Schiedam. Heinen & Hopman is also responsible for the maintenance and failure handling of the platform for the first five years of operation.
