TMMG is seeking a qualified Naval Architect – DDAM Shock Analyst (FFG(X) Program) with expertise in shock qualification analysis to support the Future Guided Missile Frigate (FFG(X)) program at Fincantieri Marinette Marine (FMM). The candidate will provide onsite support in Marinette, WI for 1-3 months, followed by remote work. The primary focus is to conduct NAVSEA-mandated shock analysis of shipboard equipment foundations weighing over 150 pounds, ensuring survivability in underwater explosion environments in compliance with MIL-S-901D and DDS-072 using Dynamic Design Analysis Method (DDAM). Key Responsibilities
Perform DDAM-based shock qualification analysis of structural foundations, pipe hangers, and critical equipment supports exceeding 150 lbs, per MIL-S-901D and NAVSEA DDS-072. Build and run finite element models (FEM) in Siemens FEMAP, applying appropriate geometry, material properties, boundary conditions, and shock load vectors. Simulate underwater explosion (UNDEX) loading per NAVSEA-approved methods, including DDAM, and validate structural response against acceptance criteria from NAVSEA Design Practices and Criteria Manual (T9070-AJ-DPC-120/3010). Evaluate yielding, buckling, and response spectra results and recommend structural improvements where needed. Collaborate with shipyard and TMMG engineering teams to resolve issues raised during design reviews, ship inspections, or trial card adjudication. Prepare detailed engineering documentation including: FEA input and output data sets, NAVSEA-compliant analysis reports, spreadsheets summarizing model inputs and acceptance margins, and ShipConstructor-compatible 3D CAD files of approved foundation modifications.
