Beachwalk WWPS

March , 2011

Global Diving & Salvage, providing Hyperbaric Consulting Services, including assistance with drafting of Hyperbaric Intervention Plan of the Beachwalk WWPS project in Honolulu, Hawaii. Global has also assisted with the design, procurement, and modification of a decompression chamber that will be used in the event that a hyperbaric intervention becomes necessary during the digging of the force main portion of the project. The new tunnel, 7 feet in diameter will be bored with a micro-tunnel machine. In the event of need for hyperbaric intervention, a bulkhead will be installed near the opening of the tunnel, the decompression chamber will be mated to the bulkhead and the compressed air workers will enter the tunnel through the decompression chamber. They will decompress on the way out if needed. Global will provide supervision of the hyperbaric events.
