DCN opens new hyperbaric test and training center

Offshore staff

BERGEN OP ZOOM, the NetherlandsDCN Diving, has opened a new hyperbaric testing and training center that the company says is unique in the Netherlands and uncommon anywhere in the world. In a hall alongside the company’s head office, a permanent professional center has been established, in which every possible hyperbaric working situation can be simulated.

This testing and training facility consists of a welding area, a testing area, a separate control room, and a saturation chamber under overpressure, with living accommodations including shower and laundry facilities. The separated welding chamber is suitable for welding and testing with a working pressure of up to 200 m (656 ft) and a testing pressure of up to 280 m (919 ft).

This will enable DCN to offer a hyperbaric welding service from a Procedure Qualification Routine (PQR) welding procedure right through to offshore environment simulation and the production of a whole range of test welds. In the adjacent testing facility, weld tests can be undertaken on large sections of pipe up to a maximum diameter of 1,750 mm (69 in).

The test space is not only suitable for test welds, but also for testing all kinds of equipment/products at pressure such as welding robots, ROVs, diving systems, control systems, kink arms, drive systems, and valves.

This hyperbaric facility now also makes it possible to train divers and welders without having to work offshore. The test facility at DCN can also test the possibilities of underwater cable repair up to a depth of 200 m (656 ft).
