D497 - Hull and External Structures - The department is responsible for supporting design and analysis of submarine hull and external structures. This includes interface with shipyard and trades to assure completed designs are producible. Responsibilities include structural engineering analysis of pressure hull shell and frames, bow and stern main ballast tanks, built-in tanks, hull and tank penetrations, external fairings, external foundations, bulkheads, and steering and diving control surfaces. Responsibilities also include interface control and integration of attached external submersible vehicles. |
Engineers work in teams by area of the ship and/or by function to develop the design from established requirements. Engineering analyses include submergence, fatigue, hydrodynamic flow loads, tank pressurization loads, shock loading (static and dynamic) and others using state-of-the-art computer methods and conventional hand calculations. Engineering reviews the design from concept formulation through detailed models to design disclosure in a Design-Build-Sustain environment as well as supports construction during the build phase. Engineers will interface with a multi-function design team and participate in Navy design reviews.
