Seaway Offshore Cables is a leader in submarine cable installation, repair and maintenance serving the global offshore renewable energy and oil and gas sectors as well as utility markets since 2003. We combine two decades of in-house cable installation experience with best practice and latest vessel technology to operate in harsh environments 24/7 minimising weather delays. The innovative Siem Duo: Cable Lay Vessel Siem Aimery and Installation Support Vessel Siem Moxie have already set new standards in offshore wind submarine cable installation.

Although initially focused on offshore wind energy projects, we are equally anticipating market developments in the fields of wave and tidal and other marine technologies such as floating offshore wind and are now a global supplier, in partnership with our parent company Seaway Offshore, of renewable energy solutions. Seaway Offshore serves the oil and gas as well as the offshore renewable energy industries with a modern, environmentally friendly and technically advanced fleet of more than forty-five vessels.

Safety is our priority, and we are leading the way with the use of ‘Walk-to-Work’ systems during submarine cable installation as well as operations and maintenance to safely increase the operability during poor weather conditions.

Our Ships. Our People. Our Vision. Your Solution.
