Helicopter Availability and

Capability•Drilling Rig Mobilization

– heavy lift helicopters (e.g., Chinook 234, Sikorsky S-64)(10,000 kg capacity)

– readily available

•Routine Service

– medium lift helicopters (e.g., Bell 212, A-star)

– readily available

 Blow-out

Avoidance and Control•Low probability (e.g.,0.3:1,000 wells or1:3,333 wells)

•Proper planning

•Experienced and supervised crews

•Stockpiling supplies and BOP equipment

•Rig ignition in minutes

•Relief well typically not required

Safety

•Many remote industrial operationswithout 24 hour access

•Require standard OHS risk assessment,OHS Schedule 1 compliance

•Road access not the first means of

emergency response•Require well trained, experienced andsupervised crew
