Unmanned surface vehicle successfully completes subsea positioning
PORTSMOUTH, UK -- Autonomous Surface Vehicles (ASV) has launched an unmanned surface vehicle for oil field services usage. Called the C-Worker, a multi-use offshore unmanned surface vehicle developed to conduct subsea positioning, surveying and environmental monitoring.
A live demonstration of C-Worker was conducted in January when ASV, alongside sister company C&C Technologies, operated the vehicle in the Solent off Portsmouth, UK. Fitted with a Sonardyne Gyro USBL acoustic positioning system, the vehicle successfully executed seabed positioning and Compatt calibration, as well as station keeping and following survey lines.
Additional technological advancements introduced in the C-Worker include the integration of a variety of offshore payload combinations, including USBL, ADCP (current meter), CTD, multi-beam sonar, acoustic telemetry, and passive acoustic sonar (PAM) for marine mammal detection. Payloads can be developed by ASV, or by customers who are supplied an empty payload frame, with a software and power interface specification. The C-Worker’s navigation sensor suite comprises C-Nav DGNSS, color and light cameras, an infrared pan-tilt camera, an x-band marine radar and AIS.
Having completed the build and commissioning of the first C-Worker, production of the second is now underway. The vehicles will be operated and leased by ASV, with options for bare-boat and full-service solutions.
