Heinen & Hopman

Heinen & Hopman was contracted by Eneco for the Luchterduinen offshore wind farm to provide both initial HVAC supply and an operations-phase 24/7 service and maintenance contract for the HVAC system installed on the Offshore High Voltage Station (OHVS). The wind farm comprises 43 Vestas V112-3.0 MW turbines totalling 129 MW, exporting power via a 33/150 kV OHVS located approximately 23 km off the Dutch coast between Noordwijk and Zandvoort. The HVAC system maintained under the contract is responsible for cooling the OHVS's high-voltage electrical components, including the transformer and switchgear rooms. Regular maintenance is intended to minimise the risk of early failures and costly downtime by keeping cooling capacity within design tolerances and detecting degradation before it impacts platform availability. Heinen & Hopman has stated that the service contract was tailored specifically to the Luchterduinen project after analysing how to reduce ongoing maintenance costs across the OHVS HVAC envelope. This role complements the platform's operations-phase electrical maintenance under the 2026-2031 Omexom contract, with Heinen & Hopman focused specifically on the HVAC subsystem rather than the broader electrical infrastructure.
