HVAC | Cable Layer Nexus

The Nexus is an innovative new cable laying vessel which has been built for international contractor Van Oord who specialises in dredging, offshore oil & gas and offshore wind. Van Oord has been involved in many offshore wind farm projects in northwest Europe. The Nexus is Van Oord’s latest addition to its range of equipment.

Gemini offshore wind park

The 123 metre vessel’s first project will be the Gemini offshore wind park, where the vessel is going to install electrical cables. Gemini is constructed 85 kilometres off the Dutch north coast. Gemini is going to be the largest Dutch offshore wind park so far, consisting out of 150 wind turbines, each with a capacity of 4 MW. The wind park will be fully operational in 2017 and is expected to deliver electricity to more than 1,5 million people.

Technical specifications

The design, engineering and build of the vessel took only 15 months and the construction took place at Damen Shipyards Galati, Romania. The Nexus has been equipped with a cable carousel with a capacity of more than 5,000 tonnes and an offshore crane that will enable it to lay heavy and long export cables. The vessel accommodates up to 90 persons.

  • 31 separate exhaust systems for technical and accommodation rooms
  • A ship-wide central heating system, powered by an oil fired boiler (capacity 1100 kW) completed with a modulating burner (capacity 1250 kW)
  • Heat recovery in order to achieve energy savings
  • All accommodation rooms are provided with a water-fed reheater to ensure the temperature in each room can be controlled separately
  • Each air handling unit has been provided with steam humidification for a comfortable indoor climate in winter
