Allseas is strengthening its subsea capabilities with a new fleet of next-generation remotely operated vehicles (ROVs) from the Schilling Robotics division of TechnipFMC. These hybrid electric Heavy Duty (eHD) ROVs combine electric propulsion with proven hydraulic capability.
The ROVs enable Allseas to modernise its fleet while maintaining the tooling compatibility and work-class performance required for demanding subsea construction, inspection and intervention projects. The ROVs can operate in water depths of up to 6000 metres.
The vehicles will gradually replace the existing ROV fleet, expanding the company’s ability to execute work across a broader range of offshore environments and applications.

Built for evolving offshore challenges
Offshore operations continue to grow in scale and complexity, with projects moving into deeper waters, more remote locations and harsher environments. The eHD ROVs are designed with these challenges in mind. Enhanced manoeuvrability, advanced navigation and automated support functions allow for more precise subsea work, improving execution and reducing time spent offshore.
Increased tooling capacity and improved vehicle performance enable a wider range of inspection, construction and intervention tasks to be carried out with a single system, giving project teams greater flexibility in how operations are planned and delivered.

Remote operating capability
A key advantage of the new fleet is remote operating capability, allowing pilots to support offshore operations from another vessel equipped with an eHD system, or from an onshore operations centre. This gives project teams greater flexibility in deploying specialist expertise while helping maintain continuity during complex campaigns.
Enhanced system monitoring and condition-based maintenance tools support more effective maintenance planning, helping maximise system availability and reduce downtime. The systems also feature more energy-efficient operation and reduced reliance on hydraulic components, contributing to cleaner subsea operations and lower maintenance requirements.

Future-ready fleet
The investment reflects Allseas’ strategy of continuously evolving its capabilities to meet changing market demands and to remain at the forefront of offshore innovation. The new fleet will be active across Allseas’ core markets – pipelay, subsea construction and heavy lift – while supporting future opportunities in emerging sectors such as offshore renewables and deep-sea mineral collection.
