1800mm Deck Decompression Chambers DDC

Over the last few years we have seen the increase in popularity of larger diameter Deck Decompression Chambers (DDC’s). Initially any enquiries for chambers larger than 1500mm (60 inches) would have exclusively come from the Scandinavian region but now we are finding that diving contractors from all over the globe are showing interest in our 1800mm (72 inches) chamber. IMCA have recently revised their D023 guidelines:

” Any chamber manufactured after 1 January 2015 should have a minimum internal diameter of 60 inches if using imperial measurements or 1500mm if using metric measurements. Chambers manufactured before this date do not need to meet this size requirement. “ 

But for some people bigger is better.
Diver Decompression Chambers

Due to the increase in demand we at SMP now stock 1800mm DDC shells at our Preston workshop ready to fit out. This greatly reduces project build times for our customers. We supply the chambers as free-standing units but more commonly as containerised systems ready to deploy anywhere in the world. We have standard designs like the example shown below which fit into 20 foot ISO containers to keep mobilisation and shipping costs to a minimum. We also produce bespoke systems and our sales and design teams are on hand to consult with clients to produce high quality solutions, supplying computer generated realistic views of the systems prior to build.

Diver Decompression Chambers

Our DDC shells are built in the UK to the design code PD5500 : 2009 CAT1 and are certified by Lloyds Register of Shipping and they have a depth rating of 100 Metres.

All of our diving systems are designed to meet and exceed IMCA safety standards for offshore use.

Please contact our sales team for further information.
