Structural Design and Analysis

Having worked on new structural designs for the UK Navy’s Aircraft Carrier(Queen Elizabeth Class), the Canadian Navy’s Joint Support Ship and the UK Navy’s RFA MARS Fleet Tanker, BMT can provide expert, affordable and timely structure solutions.

Our in-service support activities have included extensive work on the design of structural changes for the refit of the RFA ARGUS, as well as design solutions for fatigue issues, and assessment and design of structure required to support new equipment.

Design, Analysis and Verification

BMT's structural engineers and architects design and analyse structures from first principles both using hand calculations, in-house tools and specialist software packages through to the production of detailed drawings; regularly applying classifications society rules, industry and military standards.

We work across submarines, surface ships and structures, such as pontoons and gangways, to provide essential analysis and feasibility guidance at each stage of a project, from concept design to through-life vessel support.

With the aim of finding the best possible solution and anticipating costly or time-consuming issues, BMT also conduct work in support of structural certification including the production of structural design disclosure documents and condition surveys.

Finite Element Analysis (FEA)

Applying commercial FEA software tools (including ANSYS® and PATRAN®) to global and local analysis of surface ship and submarine structures, BMT have developed a broad experience and knowledge base of both linear and nonlinear structural problems. Previous FEA projects include the assessment of submarine pressure hull domes, equipment seating design, collapse strength analysis of stiffened steel panels and grillages, deck-superstructure connection analysis and whole ship strength assessment. Such a diverse project history demonstrates the variety and complexity of the projects that have been successfully completed, providing experience which can be drawn on for future projects.
