Caley Ocean Systems is presenting a Hyperbaric Lifeboat Recovery Initiative for the North Sea at Subsea Expo 2016 conference, 3 – 5 February, in Aberdeen.
Self Propelled Hyperbaric Lifeboats (SPHLs) enable the divers in saturation onboard a Dive Support Vessel (DSV) to be evacuated from the diving system in the event of a major incident. The standard for SPHL recovery is contained in IOGP 478.
However the present situation is that the SPHL is meant to head for the nearest port under its own steam and in severe weather or high wind situations it could well be the case that with a maximum of 6 knots forward speed in calm seas the SPHL might never make it in time. This presents a significant risk to the divers. One solution is to have in place a SPHL Recovery capability, which can be mobilised within hours of the SPHL launch. This presentation will report on the development of a JFD SPHL Recovery service which will utilise VOO’s (Vessels of Opportunity) pre-engineered to take a portable, side davit LARS that both recovers the SPHL from the water and then delivers it to the quayside and hyperbaric reception facility (HRF).
The presentation will describe the JFD SPHL Recovery initiative for the North Sea, comprising three side davit LARS at three coastal bases and available 24 x 7 365 days per year, together with an additional 4th ‘floating’ system. In the event of an incident a davit is deployed to the nearest nominated vessel (Moship), enabling a Time to First Rescue (TTFR) of 32 hours.
It will also review the requirements of IOGP 478, the LARS options: stern A-frame, side davit, shipboard crane and stern ramp, and the benefits of a portable side davit system. It will also describe the wider relevance and Conops implications of establishing total North Sea coverage for recovery of SPHL and recovery to a hyperbaric reception facility onshore.
