The Challenge
A marine engineering firm needed structural verification for aluminum deck hardware and support brackets on a workboat retrofit. Classification review required proof that welded assemblies would survive specified wave-impact and equipment loads without exceeding allowable stress — their internal team was saturated and ANSYS models were incomplete.
Our Approach
- Built FEA models from client STEP with appropriate weld toe modeling and contact sets
- Applied load cases from class notes: equipment static, impact factor, and combined sea state
- Identified stress hotspots at bracket transitions; proposed gusset and radius revisions
- Validated revised geometry met allowable stress with margin report
- Delivered PDF stress report with critical region callouts for surveyor package
