Our Projects

A selection of our worldwide projects, demonstrating our industry leading services


Phase 1 of the Rampion project consisted of cable loading transport and installation of 60 infield array cables with a total length of 75km. The project included all engineering, planning and project management associated with the work.

Global Symphony carried out the cable loading from the cable manufacturer in the North East of England and transported the cables from the factory to the wind farm where the cables were installed. This included fitting cable protection systems into wind farm foundations and securing the cables on the wind turbine foundations ready for termination.

Following the cable lay, the 60 cables were trenched using the Q1400 trencher with its mechanical cutting tool, to a depth of 800mm in particularly hard seabeds consisting of clays chalks and flints.

Phase 1 was carried out on time, according to plan and within budget. This work was awarded as follow on work from the successful campaigns on Eon Humber Gateway.


In the redevelopment of BP’s ETAP oil field the Q1400 trenched and buried the Machar replacement umbilical.

Global Offshore carried out all engineering and planning for the umbilical burial, with soil analysis needed to ascertain the best burial method as more sands and very hard clays were expected in this part of the Central North Sea.

Trenching plans and procedures were developed, and both cutting and jetting methods were used also utilising the Q1400 deck transfer system in order to give the most cost effective burial solution for the project.

With an overall length of 35km the Q1400 was used in jetting mode for c. 21km while the cutting tool of Q1400 was used for c. 14km.

A total of four areas were initially trenched using the Q1400 cutting tool with one switch over from cutting to jetting after which the remainder of the umbilical was trenched using the jetting system.

The entire project was completed within 24 days.
