## Summary

The Ministry of Defence in the United Kingdom is undertaking a procurement process titled "Obsolescence Rectification and Re-Design of TMCC with In Service Support," classified under diving services. This contract aims to upgrade and retrofitting Transportable Manned Compression Chambers (TMCC) that are vital for treating divers with decompression illnesses. The procurement process is currently in the award stage, with JFD Limited being awarded the contract on 13th March 2025. The project includes both a significant upgrade of outdated systems and ongoing in-service support for a period of up to eight years, with an initial five-year term and three optional one-year extensions. The process was conducted through a selective negotiation procurement method.

This tender offers a substantial opportunity for businesses specialising in commercial off-the-shelf (COTS) systems, particularly those involved in automated control systems, breathing apparatus, gas monitoring, and general system integration services. The contract not only addresses obsolescence but also involves the long-term provision of technical, management, and refurbishment support, opening doors for companies focused on sustained technical assistance and in-service support. Companies with a strong background in defence services, specifically those with experience in integrating advanced systems into existing military equipment, would find this contract highly suitable for their expertise and capabilities to compete effectively.

## Notice

Transportable Manned Compression Chambers (TMCC) are a transportable therapeutic compression chamber used for medically treating divers with decompression illnesses. There are two variants of this design - ship-fits and containerised. Ship-fits are designed to be secured to the weather deck of a ship, mounted and secured on shock mounts. The containerised version is identical in operation, apart from it is fitted within an ISO container and has additional systems, e.g., air conditioning. The TMCCs were procured in the late 1990s and are outfitted with both an electronic atmospheric control system and an emergency manually operated built in breathing system. The electronics and systems fitted for Atmospheric Control / Breathing System (AC/BS) and analysing the chamber's gas contents have become obsolete. This obsolescence has impacted the Authority's ability to refurbish and repair the equipment. To address the obsolescence issue, Defence Equipment and Support (DE&S) Salvage and Maritime Organisation (SALMO) Delivery Team (DT) is considering retrofitting (including the design and installation) the current fleet of TMCCs with modern Commercial Off The Shelf (COTS) systems. The Authority's definition of retrofitting is to identify suitable systems and design the integration / installation of equipment to the current fleet of TMCCs. This shall include, but not be limited to, systems for automated atmospheric control, breathing systems, gas monitoring and chamber dive logging. This contract will also aim to modernise auxiliary equipment fitted; examples of these items would be internal lighting, telephone system and air conditioning units. In addition to the obsolescence rectification, there is a requirement to provide continual in-service support for a period of 5 years with the potential for three additional one-year Option periods. This shall provide the Authority with technical assistance, management and provisioning of spares / repairs / refurbishments, project management and support to meetings.
