Professional diving services for industry and utilities

At Nordic Marine Service A/S, we provide professional diving services verified according to ISO 9001:2015.

We support utility companies, consultants, contractors, ports, and shipping companies with everything from underwater inspections and drone documentation to repair, cleaning, and replacement below the waterline.

A commercial diver typically performs tasks on quay structures, sheet pile walls, bridges, submarine cables, intake/outfall systems, propellers, rudders, and hulls.

We plan in close collaboration with operations so the work can be carried out while the facility is running or during a short stop. If you need in-water surveys, measurements, anodes, or propeller maintenance, we handle the entire task professionally — from initial assessment to the final report.

Contractor work, ship services, and equipment

As a diving company, we support you with underwater contracting and technical underwater work where precision and safety are essential. We work with contractors and consultants on foundations, piles, sheet pile walls, pipes, tunnels, and submarine cables. A trained commercial diver can perform mechanical assembly, bolting, cutting, and welding according to agreed methods and quality standards.

When a project requires steel, brackets, or repairs, we also offer welding services as part of the same task, giving you a single responsible supplier and everything gathered under one port.

We handle access, environmental conditions, safety barriers, and waste—and coordinate with other trades to keep the project on schedule without unnecessary complications. From planning to final handover and operation.

We provide ship services and diving support when the vessel is in port or at anchorage. Our commercial divers can perform in-water surveys, propeller polishing, rope or debris removal, hull cleaning, inspection of sea chests, anodes, and rudders, as well as emergency assistance in case of grounding or damage.
With mobile units, ROVs, and video documentation, you receive quick status updates, decision-making support, and the option to continue sailing without docking.

Our professional diving service is planned in collaboration with the agent and crew, ensuring that the operation fits smoothly into loading, unloading, and departure schedules.

We know the requirements of classification societies and flag states, and we deliver documentation that supports vessel operations.

As a professional diving company, we know a strong setup requires the right gear. The equipment we offer includes a diving container, air and nitrox supply, communications, heating, pumps, cutting tools, lift bags, pontoons, generators, compressors, ROVs, and cameras for inspection and reporting.
We respond quickly throughout Denmark and select equipment based on visibility, current, depth, and the purpose of the task.

When your company assigns a job, we align on staffing, access, vessel movements, and safety zones so everything is ready upon arrival.

Our 24/7 support means you can call whenever the situation changes, and we adjust the plan accordingly. The goal is reliable, efficient solutions that get you across the finish line without downtime, extra costs, or recurring issues.
