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.

IMCA Publishes Safety Rep Handbook

The International Marine Contractors Association (IMCA) has published a new tool for the industry – the ‘Safety Committee Representative’s Handbook’ (IMCA SEL 035), for use by safety committees on board vessels undertaking marine operations, recognised by IMCA as an excellent way of promoting and managing safety issues.

The handy wire bound A5 handbook is international in scope, and is written in straightforward and simple language. As well as providing guidance and information on a range of safety related topics it also covers the ‘nuts and bolts’ of how a safety committee works including:

• The function, remit and structure of safety committees
• How they affect welfare and the working environment
• Where safety representatives can find further information.

There is a chapter on some of the fundamental safety processes that are of importance to offshore personnel including risk assessment, safe systems of work, control of hazardous substances, manual handling, working at height and lifting operations.

It is now available for downloading free of charge for members and non-members alike at www.imca-int.com, and printed copies are available at £10 for members and £20 for non-members from publications@imca-int.com

IMCA Making Waves – SMP Hyperbaric Reception Facility

IMCA Announces Guidance on Hyperbaric Reception Facility

The safety of divers in saturation is of paramount importance. With this in mind, the International Marine Contractors Association (IMCA) – Booth S18 at OTC 2014 – has published ‘Diving Equipment Systems Inspection Guidance Note (DESIGN) for the hyperbaric reception facility (HRF) forming part of a hyperbaric evacuation system (HES)’ (IMCA D 053).
IMCA Announces Guidance on Hyperbaric Reception Facility

“D 053 should always be used in conjunction with IMCA D 018 ‘Code of practice on the initial and periodic examination, testing and certification of diving plant and equipment’,” explains IMCA’s Technical Director, Jane Bugler. “Indeed, cross references to this Code are provided where appropriate.

“Our new document addresses the provision of an HRF as part of an HES as utilised within the offshore diving industry, and aims to provide a comprehensive reference source, addressing the philosophy of what equipment and layout is required for an HRF, plus the examination, test and certification requirements necessary to meet agreed industry practice.

“This will apply anywhere in the world (i.e. outside the territorial waters of most countries or inside territorial waters where offshore diving, normally in support of the oil and gas or renewable energy industries is being carried out).”

The newly published document offers examples of good practice. It gives advice on aspects of an HRF that can be configured in certain ways in order to provide a safer system of working. It also identifies how inspection and testing can be carried out safely and efficiently.

The document has no direct legal status, but many courts, in the absence of specific local regulations, would accept that a company carrying out diving operations in line with the recommendations of IMCA D 053 was using safe and accepted practices.

Saturation Diving System Undergoing Sea Trials

SMP have manufactured a compact saturation diving system which has now been installed onto the vessel.  The system is currently undergoing sea trials over the next 4 weeks.  During this time the saturation diving system will be thoroughly tested before the system is fully commissioned.

The saturation diving system is rated to 300 metres and is Lloyds approved and also meets IMCA D 024 (DESIGN for Saturation Diving Systems).

Below is a selection of photos taken onboard the vessel which show the complete saturation diving system undergoing sea trials.

The project has taken 2 years from the initial 3D design inception from our team of experienced CAD engineers, skilled manufacturing from our dive technician engineers and onsite installation.
