We’re happy to announce that Heinen & Hopman received the order to fabricate and install the HVAC for Borkum Riffgrund 2 Offshore High Voltage Substation (OHVS). Borkum Riffgrund 2 is a German offshore wind farm.
HSM offshore – a Dutch construction yard experienced in platform, module and jacket projects for the offshore oil & gas and renewables sectors – was awarded the EPC contract for the high voltage AC transformer platform. The Offshore Substation will collect the electrical energy from the offshore wind farm turbines, transform it to a higher voltage level and deliver the power to shore.
Offshore substations require a controlled indoor climate to maintain the temperature, relative humidity and air quality within the design limits in order to ensure optimum operation of installed electrical and electronic equipment. By providing ventilation, heating, cooling and moisture control, acceptable air quality and temperature is achieved in all weather conditions. Indoor rooms will be kept at an 50 Pa overpressure in order to avoid infiltration and ingress of salt-particles, dust and saltwater aerosols.
Heinen & Hopman will supply the dehumidification system, the ventilation system (including natural ventilation), the heating & cooling system as well as the HVAC control systems. Robustness was one of the key requirements. High quality materials will be used to avoid corrosion and guarantee the 25 year lifetime of the platform. For example, only stainless steel ducting and piping will be used, as well as self-contained units with air cooled condenser coils made of titanium.
The following design conditions are considered:
