Comfort under pressure

Completion of cutting-edge diving system consolidates JFD's commanding presence in the saturation diving market.

The saturation diving system JFD has been building for a new-build vessel in Norway, is nearing completion, with the project awaiting final approval.

The six living chambers and a 15m long transfer under pressure unit form part of an exciting new 24 man saturation diving system (SDS) project put together at JFD's facility at Inchinnan, Glasglow. The SDS is designed to allow divers to live at working depth, without decompressing between deep-sea dives, for increased periods during extended subsea construction projects.

The original contract was signed with specialist subsea engineering company Divex, which was merged with James Fisher Defence to form JFD. The team has been responsible for the engineering design, procurement, manufacture, supervision of installation and then commissioning of this system.

The twin-bell system, arguably the most sophisticated diving system in the world, is designed to work at 350m water depth, weighs about 800 tonnes and uses advanced control systems for optimum efficiency. The living areas of the pressurised chambers are fitted with soft furnishings, mood lighting, Wi-Fi and Tvs to make life as comfortable as possible for divers living in a small space (2.4m x 5m) for up to 28 days at a time. Providing a comfortable, quiet and safe environment for the divers, contributes greatly to diver health and efficiency.

It also sets the benchmark for future designs, as JFD programmes director, Bill Hives explains,

'We have worked hard to develop a top-of-the-range saturation system utilising state-of-the-art technology and innovative design. It allows operators to continue working in sea states that would have previously seen the suspension of diving activities.'
