Modus Seabed Intervention has completed system integration and trialling of a hybrid unmanned underwater vehicle, which could be used in the offshore wind sector.

The company said the hybrid, which has been developed in partnership with Saab Dynamics, is one of the first autonomous underwater vehicles to feature the capabilities and characteristics of a remotely operated vehicle (ROV).

Trials took place in Sweden and the UK and the company is now preparing for commercial deployment of the vehicle.

The vehicle can be operated fully autonomously or as a tethered ROV and features a ‘thruster’ pattern that enables the vehicle to hover and operate with six degrees of freedom, Modus said.

It is depth rated to 1200 metres, which can be upgraded to 3000 metres to meet project-specific applications, the company added.

Modus said it has also developed two deployment and recovery systems; a floating dock for surface deployment and recovery and a subsea garage allowing for a full de-coupling from the support vessel.
