Glomar Offshore’s multi-purpose DP2 subsea support vessel Glomar Wave has executed a project for GeoSea on the 309MW Rentel offshore wind farm in the Belgian North Sea.
The Glomar Wave was fitted out with an Ampelmann A-type gangway system and a Schilling Heavy Duty TMS Work Class ROV system from ROVOP.
The vessel’s tasks included messenger wire installation of 42 wind turbine foundations through cable holes in the monopiles, performing of the earthing connection with Piranha clamps, visual inspection, and transfer of personnel and material by the use of the walk-to-work gangway system and the boat landing.
Glomar Wave did over 1,400 transfers with the walk-to-work gangway, under a guaranteed workability of up to 2.5mHs and 24h DP2 operations, the company said.
GeoSea carried out monopile and TP installation with its jack-up vessel Innovation, Glomar Offshore said.
The Rentel offshore wind farm is being built at water depths of between 26m and 37m, approximately 32km off the Belgian coast.
The wind farm will comprise 42 Siemens D7 type wind turbines , each with an individual installed capacity of 7.35MW, planned to be fully operational by the end of 2018.
The project is being developed by Rentel NV, a consortium of eight Belgian shareholders, including Otary Offshore Energy, DEME Group and Elicio NV.
DEME, with its subsidiaries GeoSea and Tideway, is the EPCI contractor for the wind farm.
