King County - Brightwater – West; Hyperbaric Tunneling Support

Global Diving is providing complete hyperbaric intervention support, including training of compressed air workers, manlock and medical lock operators, as well as assisted with the design and installation of mixed gas breathing systems in the chambers located on the TBM (Tunnel Boring Machine). Global also procured and modified an existing Medical Chamber as well as purchased a standard deck decompression chamber and designed and modified the chamber to serve as a hyperbaric shuttle to move personnel from the TBM to the medical chamber if needed. Global developed the hyperbaric manuals and decompression tables and provided assistance to the J.V. on pursuing and acquiring variances for the project.
