News & Events-Frazer-Nash ensures the historically accurate restoration of the HMS Alliance

Frazer-Nash has delivered technical guidance on the material restoration of the HMS Alliance submarine, which is a key exhibit at the Royal Navy Submarine Museum based in Gosport. The consultancy initially undertook a study for the Museum to identify the most sustainable long term approach to conserving the vessel, taking into maintenance access and cost of restoration. This initial study served to de-risk the project prior to the start date. Following the study, the consultancy assisted in the selection of a contractor to deliver the structural restoration work and subsequently provided technical guidance during the restoration to ensure that an accurate historical restoration was carried out. All of these were delivered with minimal disruption to the Museum as a whole.

The HMS Alliance was one of fourteen 'A' class submarines built for service in the Far East during World War 2. Launched in 1945 and gifted to the RoyalNavySubmarineMuseum in 1980, the fabric of the vessel had fallen into a severe state of degradation having been exposed to the elements. Following a decision to address this problem, the Alliance restoration project was formed in 2010 to restore the submarine to its former glory using a grant from the Heritage Lottery Fund. Three years on, the project is nearing completion with just a few minor items requiring completion.

During the course of the project Frazer-Nash supervised the work, provided heritage advice on the restoration, maintained an active risk register and resolved a total of 79 technical queries from the contractor. These ranged from addressing dissimilar metal corrosion issues, replacing corroded material whilst retaining the integrity of the submarine's history and heritage to the discovery of additional plans and how to take their contents into account during the restoration.

Wyn Davies, Associate at Frazer-Nash said "Frazer-Nash brought a unique perspective to this project thanks to the consultancy's extensive experience of working with submarines and its overall knowledge of the marine sector. This has been a fascinating and rewarding project to take part in and we hope to become involved with more heritage work like this that draws on our technical expertise"

All of the work has detailed photo records and the work carried out will be written into the conservation management plan for the vessel, ensuring the continuity of future conservation work.
