The blast room built by Hodge Clemco measures 7.6m wide by 6.2m long. It is 3.2m high and includes a 3.5m diameter powered turntable set flush in the floor. It also has a pneumonic access platform which enables staff to work on all the structures easily and safely.

Blasting is performed by a high output single chamber direct pressure unit with an RMS 2000 remote control system and dead man handle which enables operators to turn the machine on and off from the nozzle. Abrasive is recovered continuously and automatically by a mechanical scraper system that feeds it to a cleaner/separator. Clean abrasive of the correct specification is then delivered to a storage hopper above the blasting machine.

The dust extraction system has a total design volume of 16,000 cfm. The room has two folding doors at one end that are fully interlocked to prevent blasting when they are open.

The combination spray and cure booth is 7.6m wide, 8.5m long, 6.4m high and is similar in construction to the blast room. Filtered clean air enters the booth at the front and is pulled horizontally at a constant velocity to the back, which provides optimum conditions for staff to achieve a high quality finish.

A separate paint drying booth stands next to the main spray/cure booth and provides additional drying capacity to prevent production bottle necks. The hand paint booth has a similar specification.

The paint services booth and store has internal electrical supplies, sockets and lighting to Zone 1 standard, including a socket suitable for a solvent recovery unit. The design includes spillage containment and ventilation with high level filtered input and floor level extract to maintain the concentration of hazardous substances below occupational exposure limits.

Trinity House provides fixed and floating aids to navigation around the coast of the UK and Gibraltar and in the Thames Estuary, including 450 buoys for marking shipping lanes, hazards and other purposes. All the buoys are periodically retrieved for repair and refurbishment.
