Sir David Attenborough Exhaust Mounting System

The Sir David Attenborough

This government-funded project to build a new research vessel able to withstand extended time within the polar region was announced in 2014, with the designer, Rolls-Royce and shipyard Cammell Laird appointed in 2015.

Due to the nature of the vessel’s work when at sea, it was imperative that the diesel engines emitted the least noise and vibration emissions possible, both onboard and out into the natural environment. Cammell Laird, who already knew of the word class silencing properties of a Rubber Design exhaust mounting system, requested MIT bid for this portion of the vessels build.

Working from plans supplied by Rolls-Royce, the expertise of Rubber Design meant MIT were able to provide a bespoke system built precisely to design specifications. The suspension system comprised of 148 fixed-point mounts, 142 stabilisers, and 30 stainless steel bellows, forming the complete section that will hold in place the chosen exhaust system.
