Global Marine Systems Limited’s vessel Cable Innovator recently left Damen Shiprepair Dunkerque (part of Damen Shiprepair & Conversion) after extensive work including the installation of a ballast water treatment system and a 5-year survey. Global Marine Systems has been active on the cable-laying market since the industry’s earliest days and offers its clients 160 years of experience in the sector.

Cable Innovator is a multi-role vessel able to serve both energy and telecommunications sectors as well as facilitate scientific research. “The vessel is unique,” said Mr Ruppert. “She is one of the largest cable layers in the world and has a very good track record. In anticipation of the forthcoming IMO Ballast Water Convention, we have outfitted the vessel with a ballast water treatment system.”

The BWT-system, as well as being one of the main elements of the project, was also one of its more challenging aspects. “We installed the ballast water system, with all its complex piping, into a very tight space, in a very short timeframe,” explains Damen Shiprepair Dunkerque Project Manager Florent Longer. To ensure this part of the work was completed on schedule, Damen cut a strategic entrance into the vessel’s hull to speed up the installation process.

Among the other work Damen carried out on the Cable Innovator were items required for the vessel’s 5-year survey. Among these was the blasting and repainting of the ballast water tanks, fresh water tanks and vessel undersides. Damen also removed, overhauled and reinstalled the vessel’s tail shaft, three tunnel thrusters and one azimuth thruster.
