Pre-project planning & cable installation

Cable installation vessel, the C.S. Sovereign, part of the Global Marine Group fleet, has an exemplary track record working in wind farms and has installed almost 15% of all inter array cables globally. A recent addition about to join the Group fleet, the Global Symphony, is a proven asset having worked on many offshore wind farm projects.

The Global Symphony offers a cable lay spread that includes a 2,000 tonne carousel, capable of carrying up to 1,300m3 of product and two 10 tonne tensioners, three 5 tonne tugger winches and a cable lifting quadrant with an MBR of 4 metres. With approximately 400m² of available space aft of the cable lay spread, the Global Symphony is able to carry up to ten 20-foot containers of cable protection system and retains the option to carry the Q1400 trenching system spread along with the cable lay spread.

Using expert crews and in-house engineering capabilities, the Global Marine Group collaboratively has installed 850 inter array cables and 890 cable pull-ins across almost 50 UK and European wind farms.
