Our worldwide project highlights

With over 300 projects and more than 28,000 kilometres of subsea pipeline installed worldwide, we continually set new standards for excellence. Our state-of-the-art vessels excel in deepwater installation, pipelay and single lift installation, removal and transport. We design, build and execute for project scopes involving complex pipelay and heavy lift.
