SeaRoc Group has deployed its third SeaHub Communications System on the world’s first offshore Reactive Compensation Station (RCS), at Ørsted’s Hornsea Project One offshore wind farm.

The SeaHub system is supplied as an 8ft ISO DNV certified container, housing all the equipment required for communications and logistical data sharing for the 1.2GW project located 120km from shore.

The other two SeaHub units that SeaRoc Group provided for Hornsea Project One, utilised 10ft ISO DNV certified containers and included a new, unique feature to enhance the communication system’s performance. The 10ft containers had been installed with a 9 metre lattice tower in order to deploy critical communications antenna with sufficient height clearance from local obstacles to maximise VHF, AIS & UHF TETRA coverage around the site.

SeaHubs incorporate a variety of self-contained safety systems, including fire suppression, environmental monitoring, climate control, fire, flood, gas and various other alarms and a UPS.  All systems can be monitored and controlled over IP with SeaRoc Group’s Marine Management System, SeaPlanner.

The SeaHub installed on the RCS is the third to be deployed to the  
Hornsea Project One offshore wind farm, and the seventh in total to support Ørsted’s UK portfolio of projects, including Race Bank, Burbo Bank Extension and Walney Extension.  

Anthony Collingridge, SeaRoc Group Project Manager for Ørsted commented: “This particular SeaHub has received some modifications in order to support the requirements of the Reactive Compensation Station on which it was installed.”

 “Due to size limitations of the platform, we had to adapt the SeaHub design utilising a smaller container specification than we had previously, whilst still incorporating all the same capabilities and remaining compliant with DNV requirements.”

The third SeaHub was successfully deployed onto the RCS platform at Hornsea Project One during the week of the 23rd July 2018.

When operational in 2020, Hornsea Project One will overtake Walney Extension to become the biggest offshore wind farm in the world.

Turbine foundation installation underway at the site and is being completed using DP2 Innovation. The monopiles will support 174 SWT-7.0-154 turbines which when commissioned in 2020 will power more than 1 million homes. The offshore wind farm is being built in the North Sea, 120km off the coast of Yorkshire in the UK.
