ASV Global’s autonomous surface vessel successfully deployed

ASV Global has announced the successful deployment of one of its C-Worker 7 class of autonomous surface vessels for Subsea 7.

The 7m autonomous surface vessel was used to support a pipelay operation off the coast of Egypt.

Fitted with a survey suite comprising a multibeam echosounder and side scan sonar, the C-Worker 7 carried out touchdown monitoring in support of the Seven Antares pipelay vessel.

The C-Worker 7 operated for a total of 37 days. Use of the autonomous C-Worker 7 replaced the need for an additional survey vessel resulting in significant cost savings.

In addition, use of the C-Worker 7 resolved the technical challenge of surveying in very shallow waters whilst also removing the risk to personnel working at sea in small craft.

A spokesperson from Subsea 7 said: “The C-Worker 7 has proven to be a very capable vessel providing an excellent stable survey platform controlled by the Pipelay Vessel”.

Richard Daltry, Technical Director at ASV Global said “We are delighted to be supporting Subsea 7 in their quest to increase operational efficiency through the use of autonomous surface vessel technology. This operation marks a huge step in realising the potential of this technology and goes a long way to prove its operational readiness, particularly in a demanding offshore environment”.
