On-site hyperbaric medical officer (HMO), decompression schedule management, treatment chamber standby, and emergency DCI response for all hyperbaric tunnelling operations.
Decompression illness is the most significant health risk in hyperbaric tunnelling. Dedicated HMO support and on-site treatment capability are not optional — they are the difference between a safe operation and a life-threatening incident. KCC's medical support infrastructure meets or exceeds all international standards.
Compressed Air Interventions (≤3.0 bar)
Standard compressed air (CA) entry into TBM excavation chambers for cutterhead inspection, cutter tool change, and face maintenance. Conducted under IMCA D 045, HSE L96, and ADCI Consensus Standards at pressures up to 3.0 bar.
High-Pressure Compressed Air — Heliox / Trimix
High-pressure interventions above 3.0 bar using heliox or trimix breathing mixtures to eliminate nitrogen narcosis and reduce DCI risk. Conducted under IMCA D 045 (High Pressure Compressed Air Supplement) and EDTC HPCA decompression tables.
Saturation Hyperbaric Interventions
Saturation-based hyperbaric interventions for extended TBM maintenance campaigns, eliminating repeated decompressions and DCI risk. Workers live at intervention pressure via a pressurised transfer shuttle (PTS) for multi-day campaigns.
