The C-Worker is an unmanned surface vehicle (USV) designed for offshore services in the O&G industry. The multi-role offshore USV is designed to conduct subsea positioning, surveying and environmental monitoring without the need of a ship on station or seabed anchoring. Autonomous Surface Vehicles Ltd (ASV Ltd) is a UK company and part of Global Fusion, a privately owned international marine services group based in Lafayette, Louisiana, USA. The small robust design incorporates an aluminum self-righting hull that makes the vehicle suitable for harsh ocean environments. At only 5.85 meters in length, a beam of 2.2 meters and a height of 4.75 meter with its mast extended, this USV is a much cheaper and compact option for some offshore jobs that today are done by much larger vessels.

A look at how DP systems work and their importance to ships, vessels and rigs working on offshore O&G operations. The main contribution Kongsberg has made to the offshore O&G industry was by developing DP systems for diving support vessels in the 1970s. This significantly increased the efficiency and safety of diving operations. Since then, the offshore and maritime industries have benefited from the advances made to their DP systems. In more recent years these advances have been applied to the cruise industry with dynamic positioning systems for maneuvering and the complex task of precise position keeping. For optimal deepwater drilling the Kongsberg Riser Management System (RMS) assists in all phases of the drilling operation.
