DeepOcean Executes Remote-Managed Subsea Intervention Offshore

DeepOcean has completed its first subsea intervention project with offshore operational leadership managed entirely from shore, demonstrating a new operational model for remotely coordinated offshore services. The operation was carried out for Aker BP at the Idun Nord field in the Norwegian Sea using a work-class remotely operated vehicle (ROV) controlled through an onshore remote operating centre (ROC).

The project combined remote subsea intervention, subsea crane operations, and close-proximity vessel positioning while transferring key offshore management functions to DeepOcean’s ROC in Haugesund, Norway. A second ROV remained operated directly from the offshore vessel during field execution.

Remote Subsea Operations Reduce Offshore Personnel Requirements
Subsea intervention campaigns involving vessel positioning and heavy subsea operations traditionally require offshore deployment of shift supervisors and engineering personnel for extended rotations, often lasting up to 14 days. In this operation, critical supervisory and engineering functions were executed remotely during a single 12-hour shift from shore.

According to DeepOcean, relocating operational leadership onshore reduces offshore personnel exposure while improving vessel utilization efficiency and lowering logistics-related emissions. The approach also allows specialist engineering resources to support multiple offshore campaigns without physical mobilization.

The operation relied on real-time communications infrastructure and digital operational systems provided by Remota to maintain continuous coordination between the vessel, ROV systems, and onshore personnel. The setup supported live subsea monitoring, operational decision-making, and remote execution management during intervention activities.

Expansion of Digital Offshore Service Delivery
DeepOcean has been developing remote subsea capabilities since its first remote offshore campaign in 2018. The company has progressively expanded the complexity of remotely managed operations, including subsea dredging activities completed remotely in 2025.

The latest project demonstrates the growing maturity of remote offshore operations within the subsea services sector, particularly for intervention scopes requiring coordinated vessel positioning, tooling operations, and dynamic operational oversight.

For offshore operators, remote operational models may improve campaign flexibility by allowing different specialist teams to support multiple intervention scopes during the same vessel deployment. The approach also aligns with broader offshore industry efforts to reduce personnel offshore, optimize vessel utilization, and lower operational emissions through digital infrastructure and remote-control technologies.

DeepOcean stated that remote and digitally enabled subsea operations remain a core part of its long-term offshore services strategy focused on operational efficiency, safety, and lower-emission offshore execution.
