Active in the shallow, coastal waters of the Gulf of Mexico during the 1950s, our offshore operations expanded to greater depths around the world, installing almost every structure in Qatar’s North Field and setting pipelay records throughout the South China Sea. In the Caspian, our installation services have played a dynamic role supporting offshore field developments since the early 1990s.
Our versatile fleet of construction, pipelay, cargo and support vessels is growing. Plans are under way to further enhance our subsea and deepwater capabilities by upgrading our derrick/pipelay vessel DB50. Additionally, we have added the subsea specialty marine construction vessel North Ocean 102 (NO102) and are building a second specialty marine construction vessel North Ocean 105 (NO105). Our new pipelay vessel (LB32) supports shallow-water work that still dominates many areas of the world.
We perform installation, repair and salvage of substructures, topsides, pipelines and subsea systems, and our DB50 has a single lifting capacity of 4,400 tons. For structures above this weight, alternative, economically viable solutions from our installation engineers include dual lifts and float overs for large topsides. As a core technology with an 18-year history, our float-over capability has advanced through upgrades and customization of our I-650 installation barge.
Pipelay systems include S-Lay, J-Lay, Flex-Lay and Reel-Lay. Our high-quality welding and excellent production rates meet stringent welding criteria through our advanced Automatic Welding Systems (AWS), complemented by welding development centers worldwide and a dedicated Multi-Joint Welding facility.
A team of professional divers assists on worldwide projects. Three saturation diving systems are transferable to all our major construction vessels and dive support vessels are strategically based across our regions.
Today, our installation services are expanding to deeper waters of the Atlantic region, offshore Brazil and West Africa.
