Hyperbaric Management

HBC has been in charge of operating and maintaining the national hyperbaric treatment facility of Copenhagen University Hospital “Rigshospitalet” since 1998. Whilst tending to diving related injuries, the hospital also treats a variety of acute and elective treatments not related to hyperbaric injuries.

In addition to the national hyperbaric chamber, we own and operate our own Hyperbaric Chambers for Offshore use, which are situated on our vessels HBC Achiever and HBC Supporter, forming part of the integrated diving equipment on board.
