Surface Supplied Diving

Controlled, professional and reliable

At DCN Diving, Surface Supplied Diving is our standard for complex and safety-critical underwater operations.

With this method, the diver receives breathing gas directly from the surface through an umbilical. The system also provides continuous communication and monitoring by the dive supervisor, allowing longer bottom times and full control during inspections, construction and repair activities.
