ASV has introduced a new multi-use offshore unmanned surface vehicle (USV) called C-Worker. The USV has been developed to meet the meet the unmanned systems requirements of the oil and gas and offshore survey sectors.

Capable of conducting subsea positioning, surveying and environmental monitoring, C-Worker was demonstrated to members of the oil and gas and offshore surveying industries in the Solent off Portsmouth in January. 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.

C-Worker can be integrated with a variety of offshore payload combinations including USBL, ADCP (current meter), CTD, Multibeam 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 and a software and power interface specification.

The C-Worker’s navigation sensor suite is comprised of C-Nav DGNSS, colour and light cameras, an infra-red pan tilt camera, an x-band marine radar and AIS.

Dan Hook, director, ASV, said: ‘The C-Worker represents a new way of working, enabling customers to operate safely in the most challenging environments, reducing the risk to personnel and saving costs.’

With the build and commissioning of the first C-Worker complete, ASV is now underway with the production of the second. The vehicles will be operated and leased by ASV with options for bare-boat and full service solutions.
