I was the safety diver for the local commercial diver school, not long ago when they had the annual safety drills and mock up of 'abandon ship' and deployment of the liferafts. Didn't have to do much though, evrything went without a hitch, just recovered the hard shells of the life rafts, and hung around incase anyone got trapped under the upturned liferaft while they tried re-rite it during a simulation test, which thankfully nobody did.
