Pre-project planning & cable installation

A total solution from route engineering, project engineering through to the installation phase

As part of the Global Marine Group, Global Offshore shares in an unprecedented track record of installation of subsea cable that dates back to 1850.

In the 165 years since, the Group has installed in excess of 300,000km of cable which equates to 21% of the world total, enough to circumnavigate the globe seven and a half times.

The Group has been in offshore wind since its conception and was responsible for installing the inter-array cables at the UK’s first offshore wind farm Blyth in 2000, at Europe’s first commercial wind farm Horns Rev in 2002 and at the UK’s first commercial wind farm Kentish Flats in 2004. Since then, the Group has worked at 50 wind farms across Europe.

Whether the need is for an interconnector or links to an offshore energy grid, Global Offshore has a culture that is committed to delivering safe, innovative solutions utilising the company’s outstanding engineering and project management capability, adapting to each project’s specific needs.

Cable installation at an offshore wind farm development is a critically important phase. There were reportedly as much as £213 million in insurance losses from 28 UK offshore wind claims between 2002 and 2015, 68% were directly due to cable faults occurring predominately during the construction phase.

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.
