Frazer-Nash to help restore historic submarine
HMS Alliance, the only surviving
World War 2 submarine in the UK,
is 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 HMS Alliance, the last surviving ‘A’ class submarine, is to be
evaluate their current strength restored.
and stability. The survey will
also investigate the integrity of the periscope support structure.
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.’
After Frazer-Nash has completed the planning phase of the project, the submarine will
then undergo her physical restoration stage. The submarine is the last surviving Amphion
class (also known as the ‘A’ class and Acheron class) submarine. She was originally
intended for use in the Far East, and has a number of features that allow for much larger
patrol areas and longer periods at sea than standard British submarines of that era.
