ADC Vs. IMCA parte 2
Hola a todos:
Me he encontrado esto en el foro de www.offshorediver.com:

Yo no tengo tiempo ahora para traducirlo ahora, a ver si este finde puedo.
Un saludo

I found this on the vessels computer and believe it was written some time ago by a Mr. Merriman at Global.
U.S. Diving Companies Shifting to IMCA
IMCA/ADC:
The biggest difference in IMCA and ADC comes down to two things:
1. IMCA requires a hyperbaric rescue system ADC does not.
2. IMCA requires HRC to have environment control system also.
3. IMCA requires far more paper work than the ADC. Most of this extra paper is of very little use as far as diving safety is concerned.
4. IMCA requires the following
Diving Supervisors to be IMCA certified.
Life Support technician to be IMCA Certified.
System Tech’s to be IMCA Certified.
Superintendents must hold saturation supervisors certificate.
5. Two sat supervisors required per shift, i.e., 4 supervisors per 24-hour operations.
6. All offshore personnel must undergo an offshore survival, IMCA approved school.
7. Air divers to be IMCA Part I certified
8. Sat Divers to be part IMCA Part II certified
9. Surface gas supervisor to be IMCA sat supervisor
10. Surface gas divers to be IMCA part II certified.
11. Tender divers will also need to be IMCA certified.
12. Minimum two DMT divers per shift.
13. All divers to undergo an IMCA recognized first aid course.
14. IMCA requires chambers to be a minimum 52” dial.
15. All DDC to have scrubbers installed.
Impact to U.S. companies
• IMCA does not recognize any US training for divers and support personnel.
• Equipment Requirements not normally used by US companies
• Hyperbaric rescue system for all saturation systems.
• Oxygen Analyzers with high and low audible/visual alarms on all diver supply lines
• Voice recordings of all dives (diver and supervisor) kept for 24 hours after each dive.
• Carbon Dioxide Analyzers with audible/visual alarm if using reclaim systems and in other conditions if deemed necessary. (no clear guidance here)
• All Diver winches must be certified man-riding
• Winches, secondary recovery system to recover basket/bell must be made available (man-riding).
• Winches, an independent secondary power source must be available
• Winch operation, breathing apparatus complete with communications to be available in the event of fire or fumes.
• Dive baskets to be fitted with top protection to prevent falling items hitting diver.
• Non-Rotating 8 to 1 safety factor required on all lift wires
• All lifting equipment requires test certificates, NDT inspections at 6-month intervals.
• All helium diving gas is required to have a minimum 2 oxygen added, this will result in a significant extra cost for gas.
• 90m3 (3200 cu ft) of breathing oxygen must be available for emergency treatment procedures at all work sites
• Independent dive panel for the st/by diver
• Breathing apparatus complete with communications to be available in the event of fire or fumes.
• No diving using the live boating operations technique.
• IMCA requires a double lock recompression chamber at all dive sites. Complete with a medical lock fitted to the main chamber lock. The external medical lock door to be fitted with an interlock device to stop door from opening under pressure.
• IMCA imposes working periods restrictions not required by ADC that may very well result in larger crew sizes on many jobs. One example is the 4-man saturation dive, impossible using IMCA working period restrictions.
• IMCA restricts air diving to 164 FSW and HE02 diving to 246 FSW, also dives between 164 FSW and 246 FSW have a maximum bottom time of 30 minutes. The much more expensive closed bell diving techniques must be used to exceed these depths or bottom time.
• IMCA guide line surface gas (HE02) diving to 175FSW with maximum 30 min bottom time (inspection dives only)
The above does not necessarily represent my views.
