Hyperbaric evacuation systems
Two independent hyperbaric evacuation units (HEU) on each diving support vessel (DSV)
Grace period of 3 years for existing DSVs Existing DSVs may operate in grace period if HEU is
free to be launched – not restricted by e.g. platform Very pleased with the IMCA initiative on
standardisation of HEU flanges

Depth/time restrictions
Restating the 180 meters «limit» for «normal diving» as the reference for time limits; Working period (14 days/10 days) Bell run (8 hrs/6 hrs) In water time (4-6 hrs/3 hrs) Time between saturations (1X last sat./2X last sat.)
Time limits as stated in the 1991 regulations for Manned Underwater Operations (MOU)

Hyperbaric Evacuation Units
Requirements for the boat structure itself as for any other lifeboat (see next slide)
Requirements for the launching arrangements as for any other lifeboat (ref NORSOK R-002)
For design of flanges the IMCA D 051, Hyperbaric Evacuation Systems (HES) Interface Recommendations, should be used
Other references: IMCA D 052 – Guidance on Hyperbaric evacuation systems. Maybe too late to be included this year

Taking diving far north….
No spesific regulatory elements considered to be changed pt due to geographical area
Present regulations should be adequate, focusing on risk and risk management
May need to reconsider if/when spesific operations should arise
