MIT has delivered a bespoke exhaust suspension system for the 128m, 5,000t Sir David Attenborough polar research vessel.

Due to the nature of her work in natural environments, the critical challenge to the diesel engine exhaust system is the ability to run at full power while emitting the least noise and vibration possible, both within the vessel and into the marine environment.

Rubber Design, supplier of solutions for noise, vibration and shock related problems, was chosen to provide a bespoke suspension system.

The system - comprising 148 fixed-point mounts, 142 stabilisers and 30 stainless steel bellows - will hold the exhaust system in place.

On schedule

MIT provided local technical and logistics support while also ensuring that each of the 320 individual components was delivered on time to each job location, ensuring that the build plans were on schedule.

Designed by Rolls-Royce, the vessel is set to be the first of its kind. She will have the ability to carry a scientific cargo of approximately 900 cu meters with an icebreaking capability of up to 1m thick at 3 knots and will be able to withstand up to 60 days at sea within the Polar regions.

The vessel is fitted with twin Bergen B33:45L6A (each 3,600 kW) and twin Bergen B33:45L9A (each 5,400 kW) diesel/electric engines to improve fuel consumption and reduce environmental impact.

She will be operated by the British Antarctic Survey and is due to enter service in 2019.
