Koosha 1 divers

Eric, they didn't make it to the HLC.
The vessel was overloaded with double stacked gas racks and cement silos - which for a pissy little boat which could normally just about manage a mobile sat system was criminal.
Working up in Iran, in bad weather went to turn and took a list.
Equipment tore loose from the deck, silos, racks, and the sat control van, she ran under in less than 4 minutes.
If I have understood correctly some of the kit that tore loose ripped up deck plates, leading to rapid flooding. It may have been the case, given the ambient temperatures, that hatches were left open which should have been closed in foul weather - I expect that will eventually come out of the mix.
The divers were found in the chamber, meaning there was no chance to transfer, and quite likely that many of the services / hoses / valves etc were knackered. Their storage was 60 odd meters, the vessel went down in 70m.
A couple of other personell were found in the wreck by divers from the Dulam Providence, one being the Client Rep still clutching the radio handset.
It is unlikely under the circumstances that even if they had managed to scuttle through to the HLC that they would have been able to launch / survive - there simply would not have been enough time.
None of these deck systems have clamps etc which can be released from within the HLC in the event of a rapid abandonment of the vessel, to my knowledge.
Consider that the Norsok/NPD requirements measure suitable and sufficient time in the order of tens of minutes for transfer, launch and move to a safe distance for SPHL's on what could be termed "capital vessels",(self-propelled hyperbaric lifeboats), the HRC's (hyperbaric rescue capsules/chamber) generally require a crane for overboarding for the older versions, hydraulic ram or chain blocks to clear them from the clamp / system.
Very sad day, my thoughts are with the families and friends.
It will be a measure of the Middle East diving community, and Iran in particular, to see what comes of this.
