New Seawork exhibitor OceanAlpha has unveiled its new 24-metre-class V180 USV–ROV System, designed to support deep and offshore subsea operations.
The V180 USV–ROV System is a deep-sea unmanned operational platform integrating a DP2-enabled offshore USV, and a work-class ROV dedicated for subsea inspection, maintenance, and repair missions up to 3,000 metres.
At the core of the system is the V180 deep-sea operation USV, a multi-purpose unmanned platform with a full-load displacement of 180 tonnes. Featuring a dual-moonpool configuration and an open deck layout, the platform enables flexible deployment of a wide range of mission modules, including a 2-tonne work-class ROV integrated into the system architecture.
The system supports subsea operations at depths of up to 3,000 metres and offers an endurance of up to 30 days, allowing rapid transition between deep-sea engineering, subsea surveying, and oceanographic research missions.
The V180 USV supports three operational modes—autonomous navigation, remote control, and crewed operation—allowing flexible deployment according to mission requirements and regulatory conditions.
Safety was a central consideration in the design of the system. The V180 is equipped with a DP2 dynamic positioning system, enabling high-precision station-keeping during operations, and features a dual Starlink satellite communication system to support shore-based remote control.
Operators can precisely control both the USV and the deployed ROV from an onshore control centre. This operational approach eliminates the need for personnel to work in hazardous sea states and high-risk offshore environments, effectively removing human exposure to operational risks and significantly reducing the likelihood of injury.
OceanAlpha offers a full spectrum of USV platforms ranging from the 4.5-metre M40P, the 7.5-metre L25, and the 8.5-metre L42, to the 24-metre V180 USV-ROV system, as well as the upcoming 15-metre V11 USV-ROV system. This tiered fleet structure enables mission coverage from nearshore environments to extended offshore and deep-sea operations.
