UK. Frazer Nash to assist in restoration of World War II Royal Navy submarine HMS Alliance

Tuesday, 27 May 2008

HMS Alliance, the only surviving World War 2 submarine in the UK, is going to be restored to her former glory thanks to the support of systems and engineering technology consultancy Frazer-Nash.

The ‘A’ class submarine is a key exhibit at the Royal Navy Submarine Museum in Hampshire. However over the years she has suffered from corrosion and degradation, which has left her in need of restoration.

As part of the initial restoration phase Frazer-Nash will perform a survey and structural analysis of the bow and the stern to evaluate their current strength and stability. The survey will also investigate the integrity of the periscope support structure. The analysis and subsequent report will look at the current conditions affecting the vessel and then make recommendations for a suitable conservation management plan.

Andy Gill, Frazer-Nash Group Leader for Marine Technology, says: “HMS Alliance is a grand and unique structure, so we will be drawing upon our full range of Naval Architect and marine engineering expertise to help in her restoration. The primary aim of the task is to use modern design and analysis techniques to bring the vessel back to life, without compromising the intentions of her original design.

This will be the first and arguably most crucial stage of the restoration process as it sets the scene for the physical restoration of the vessel. On completion of this stage, a suitable and efficient conservation programme can then be put in place to ensure the submarine’s long-term sustainable preservation. While it is inevitable that such an old structure will be at risk from the elements, our work will recommend ways to overcome those risks and safeguard her future.”

After Frazer-Nash has completed the planning phase of the project, the vessel will then undergo her physical restoration stage.

The vessel is the last surviving Amphion class (also known as the "A" class and Acheron class) submarine, and was designed during World War Two. She was originally intended for use in the Far East, and contains features that allow for much larger patrol areas and longer periods at sea than standard British submarines of that era.

Andy added: “We are really proud to be working on such a major piece of history and to be given the opportunity to help bring her back to life. Our mission is to ensure that the vessel remains an exhibit for many years to come.”
