Job description


To execute, evaluate, deliver and manage complex engineering and/or cross functional tasks or programmes of work recognising stakeholder and customer requirements. Also to identify and implement opportunities for personal and team development to ensure that professional capability of the business and individual are maintained and improved.

The Structures department (SED) is a specialist team of Engineers, who together provides the business with the capability to design all of the major structural elements that make up a nuclear submarine. This includes the pressure hull, decks, tanks, bulkheads and external structures that make up the bridge fin, casing, forward and aft external structures. The department also provides a stress analysis service to other functions in particular pipe stressing, although the group do not own or design any piping systems, it undertakes flexibility analysis and can influence these arrangements. The team has relied on external specialist services for the design of composite elements such as control surfaces and casing structures. The group also assists with the design of minor structures and components such as seats, flanges, penetrations, eye plates, pipe supports etc. In the past the group has held design responsibility for major surface ships such as LPH, LPD, AO and elements of QEC Carriers.
