For over 120 years, MRS Training & Rescue has developed specialist skills and knowledge from working in dangerous environments and rescuing mine workers trapped in rescue situations. This experience has ensured that we are the foremost company in the world for dealing with confined and enclosed spaces training and rescues.

Our history and expertise led us to now offer Maritime enclosed spaces training and rescue services. We conducted an intensive study of enclosed spaces in marine environments and engaged with multiple enclosed spaces on ships. This allowed us to apply our specialist knowledge and experience into developing courses and consultancy specifically for the Maritime industry. Most recently, we have created state of the art facilities at our centre in Southampton, to offer the full suite of STCW Basic Safety Training – essential for anyone working on board vessels at sea.

Why choose MRS Training & Rescue for your STCW Training?

Why might I need Enclosed Space Consultancy?

In the Maritime industry, it is recognised that enclosed space problems, coupled with increasing accident rates, cannot be ignored - but there is very little existing specialist assistance, training or advice available.

Frequently asked questions

Rescue from an enclosed space is a highly specialised procedure. MRS Training & Rescue uses its 115 years of experience, alongside today's most up-to-date intensive training programmes onboard new and old ships, to provide a ‘best practice' and effective safety

service to the Maritime Industry. We specialise in rescue techniques connected with every type of enclosed space situation.

We can also supply a fully equipped, self-contained rescue team on-site for use during high risk enclosed space work, thereby alleviating the pressures placed upon the crew to divert valuable human resources from their day to day work activity.

Our years of experience rescuing from enclosed spaces and training those people working in them has enabled us to adopt very strict requirements for the equipment that we use and recommend. We are only prepared to recommend equipment for sale which, through extensive testing and ‘on the job’ use, has proven to be fit for purpose.

We would be delighted to discuss individual company requirements and, if necessary, visit any ship or marine site to evaluate your equipment needs.

Confined and enclosed spaces have been around for a very long time. There is a vast amount of published material warning of the dangers, and there’s plenty of technology, equipment and training already developed to enable persons to enter and work safely in these spaces, and yet – people are still killed in them.

The Merchant Shipping (Entry into Dangerous Spaces) Regulations 1988 defines a ‘dangerous space’ as being any enclosed or confined space in which it is foreseeable that the atmosphere may at some stage contain toxic or flammable gases or vapours, or be deficient in oxygen, to the extent that it may endanger the life or health of any person entering that space.

The International Maritime Organisation (Resolution A.1050(27) – Revised Recommendations for Entering Enclosed Spaces Aboard Ships) defines an “enclosed space” as a space which has any of the following characteristics:

  • Limited openings for entry and exit
  • Inadequate ventilation; and
  • Is not designed for continuous worker occupancy

This includes, but is not limited to:

  • Cargo spaces
  • Double bottoms
  • Fuel tanks
  • Ballast tanks
  • Cargo pump rooms
  • Cargo compressor rooms
  • Cofferdams
  • Chain lockers
  • Void spaces
  • Duct Keels
  • Inter-barrier spaces
  • Boilers
  • Engine crankcases
  • Engine scavenge air receivers
  • Sewage tanks
  • Adjacent connected spaces

This list is not exhaustive, and a list should be produced on a ship-by-ship basis to identify enclosed spaces.

The atmosphere of any enclosed or confined space is potentially dangerous. The space may be deficient in oxygen and/or contain flammable or toxic fumes, gases or vapours. Where possible, alternative means of working which avoid entering the space should be found.

If a ship or vessel is made fast to the shore, then the spaces on that vessel are classed as confined spaces and fall under the Confined Space Regulations 1997. Those spaces only become enclosed spaces once the vessel is at sea, and the Maritime and Coastguard Agency have developed a Code of Safe Working Practices for Merchant Seafarers 2015 which gives guidance for seafarers when working in enclosed spaces.

The atmosphere in holds, bilges, bulkheads, cofferdams and other enclosed spaces on ships presents potentially deadly risks. It is a sad truth that proportionally more seafarers die in accidents in enclosed spaces than in any other accidents at sea. A lack of awareness, training and rescue drills can mean that safe ways of working in enclosed spaces are all too often ignored or poorly implemented.

Of the data reported by the Marine Accident Investigators International Forum and to the International Maritime Organisation in 2009, and updated with the data available up to 2017, it is suggested that there had been 145 international enclosed space incidents over a period of 19 years (1998 – 2017).

Around 75% or 103 reported deaths since 1998 could have been prevented if people had available and were trained to use a simple gas detector, with the average cost of the initial purchase being between £400 and £500, and as low as £150 for a single sensor oxygen monitor. Remaining deaths could have been prevented if the space had been adequately categorised, the implications of the cargos considered and systems in place to prevent unplanned entries.

Billy Greer, Safety Advisor, Maersk Oil UK

Would highly recommend MRS Training & Rescue. Recently attended STCW Personal Survival Techniques (PST) Course. I was very impressed with the high level of instruction being taught, things I never learnt on previous courses with other companies. Professional instructors in a relaxed environment. Was made to feel relaxed with some worries I had and given some one on one tutorial which is above and beyond anything expected.
