Submarine Support – A Tale of Two Worlds, UDT 24

Nigel Whybrow

Future Submarines & Technology Director
Babcock International Group


Nigel considers himself very fortunate to have worked all his career in the underwater systems arena and to have done so with insightful people, on interesting and demanding projects when invention & experiment were seen as essential activities.  His involvement has spanned high level concept and analysis work (as Project Lead) to the management of super-specialist teams and the direction of operational and material support for submarines at Chief Engineer level.

Fundamentally an engineer with a background in the thermodynamics and fluid mechanics of powerplants and high speed propulsion, his work responsibilities have included the definition of novel underwater vehicles and their operational integration.  At Marconi Underwater Systems in the 1980s he was technical lead for very early investigations into AUVs where the issues were ‘what could and should an autonomous vehicle be asked to do’ as much as how could it be done.

Nigel is the Future Submarines & Technology Director at Babcock International Group where he is involved in future design and technology planning and in external consultancy.  He is a Fellow of both the IMechE and RINA and author of numerous papers including many presented at UDT.

Tim Vickery
Senior Principal Scientist

Defence Science and Technology Laboratory – UK Ministry of Defence


Tim is part of the Underwater Effects Team at the UK MoD’s Defence Science and Technology Laboratory (DSTL) based in Hampshire.  He joined there around twenty years ago and worked on underwater acquisition support including the ASTUTE programme.  A wide variety of underwater projects followed and now he mostly provides advice and review to a wide range of activities across the breadth of underwater science and technology within the MoD and with industry.

Prior to joining DSTL he served in the Royal Navy for over twenty years as a Navigator, Anti-Submarine Specialist and then a variety of Staff roles including Northwood Operations and acquisition projects at Abbey Wood in Bristol.

Being part of the UDT Technical Committee is an enjoyable experience, providing an excellent opportunity to meet new people and catch-up with old friends whilst contributing something back to the underwater community.

Outside of work he spends time dismantling and attempting to reassemble a fifty year old motorbike.  His wife seems okay with the time spent in the garage.
