Saturation Diving Vessels require a rescue contingency for their divers in the form of a hyperbaric lifeboat (HLB).

In the event of an emergency evacuation, hyperbaric lifeboats accommodate saturation divers for up to 72 hours using on-board life support during which time the vessel is transported to a facility where the divers can be safely decompressed.



JFD has supplied over 135 integrated and modular saturation diving systems, with associated SPHLs, to clients around the world for the past 40 years which includes some of the most advanced systems in existence.

Davit Systems

JFD can supply davit systems which are purpose built for handling payloads in high sea states and hazardous conditions.

SPHL davits are typically mounted on the ship's side structure and use a 'dead-ship' stored energy system for autonomous deployment.
