Transfer Under Pressure System

The system is equipped for air diving and mixed gas diving and the clump weight also incorporates a tool basket for the divers. A hyperbaric floataway chamber is optional. This compact modular system consists of a 3 man 4.7m3 saturation diving bell, diver’s gas control panels (air/mixed gas), main Bell/Diver control panel, twin lock decompression chamber, single lock decompression chamber (optional), HP and LP compressors, gantry launch and recovery system. The Diving System is a mobile and modular system that can be mobilised on a DPII support vessel, platform, rig or construction barge. The system is designed for moon pool or over the side operations. Using Trimix or Nitrox gas mixtures will allow longer duration in-water bottom time at greater depths than using air diving techniques which cause longer in-water and decompression practices. By providing a closed bell system the divers are transferred in a protected environment. Safety is increased by removing the threat of Nitrogen intoxication. This is achieved by making sure at no point is the diver exposed to atmospheric pressure during decompression.
