Commercial diving services
Our core service: qualified commercial dive teams working on civil infrastructure below the waterline. Teams are deployed with surface-supplied equipment, two-way communication and topside support, so work can be directed, recorded and verified from the surface.

In detail
Commercial diving is the working end of civil engineering: the same inspection, repair and construction disciplines used above water, carried out by qualified divers in ports, canals, rivers and industrial water systems. Every team works surface-supplied, which means the diver has an unlimited air supply from the surface, hard-wired two-way voice communication and a helmet camera, so the supervisor can direct the work, ask questions and record what is actually found on the structure.
Most inland and port work happens in low or zero visibility. That is not an obstacle but a working method: divers survey by touch along guidelines, work to a fixed sequence agreed on the surface and report section by section. Because the water is rarely clear, the value of the job sits in the discipline of the method and the quality of the record — measurements, photos, video and a written condition report you can hand straight to an asset manager or engineer.
We work for port authorities, waterway managers, municipalities, civil contractors and industrial sites across the Netherlands and Belgium. A job can be a two-hour check on a lock gate, a week of concrete repair on a berth, or standby diving support for months on a construction programme. In each case the commercial part is the same: a written dive plan, a named supervisor, a standby diver, agreed hold points and a report that closes the file.
What you receive

Working method
Each job starts with a site review and a written dive plan. On site the team sets up dive control, checks communication and air supply, and works to an agreed sequence. Findings are recorded on video or in a written report and handed over with clear recommendations.
Equipment and techniques
- Surface-supplied diving systems
- Helmet communication and video
- Hydraulic and pneumatic tools
- Underwater cutting and welding sets
Safety considerations
- Project-specific risk assessment
- Standby diver and topside supervisor
