The Senior Marine Fabrication Engineer leads the engineering support for the design, planning, and execution of marine structural and piping fabrication projects. This role is responsible for ensuring technical accuracy, regulatory compliance, and build efficiency in the fabrication of hull structures, piping systems, and integrated outfitting components for naval, commercial, or offshore vessels.
Lead the preparation and technical review of structural and piping fabrication drawings, spool packages, and welding documents.
Oversee the development of material take-offs, nesting plans, weld maps, and isometric layouts for both steel structures and piping systems.
Interface with design, planning, QA/QC, and production teams to ensure smooth execution of build sequences and installation processes.
Resolve complex shop floor issues and engineering queries (RFIs, NCRs, TQs) related to structural fit-up, pipe routing conflicts, and integration.
Ensure compliance with classification society rules (ABS, DNV, Lloyd’s), shipyard standards, and applicable codes (ASME B31.3, AWS D1.1, ISO).
Support and review welding procedure specifications (WPS), procedure qualification records (PQR), and welder qualifications.
Conduct design and buildability reviews, clash detection, and spatial coordination using 3D models and digital shipbuilding platforms.
Provide technical oversight during pressure testing, dimensional inspections, and pre-commissioning of piping and structural systems.
Lead engineering change management, drawing control, and document traceability.
Mentor junior and mid-level engineers, reviewing their work for accuracy, compliance, and constructability.
Contribute to process improvement initiatives, including lean fabrication strategies and digital engineering workflows.
Bachelor’s or Master’s degree in Mechanical Engineering, Marine Engineering, or Naval Architecture.
7–12 years of experience in marine or offshore structural and piping fabrication, with significant on-site or production support exposure.
Expert knowledge of structural steelwork, pipe fabrication techniques, welding processes, and outfitting integration.
Proficiency with CAD and 3D modeling software (AutoCAD, ShipConstructor, AVEVA Marine, SolidWorks) and familiarity with P&IDs, isometrics, and GA drawings.
Deep understanding of industry codes and standards (ASME B31.1/B31.3, AWS D1.1, ABS, DNV, MIL-STD, ISO 9001).
Strong leadership, troubleshooting, and cross-functional coordination capabilities.
Excellent communication and reporting skills, including interaction with clients, classification societies, and inspection authorities.
Certified Welding Inspector (CWI), CSWIP 3.1/3.2, or similar certification.
Experience in defense shipbuilding, offshore EPC, or high-spec commercial vessel projects.
Familiarity with digital fabrication workflows, model-based definitions (MBD), and ERP/MRP systems.
Exposure to GRE/Cu-Ni piping, modular block construction, and pre-outfitting strategies.
Office and fabrication yard/shipyard environment with frequent field inspections and walkdowns.
Must be able to work in confined spaces and elevated areas during inspections.
PPE use required; some extended hours or shift coverage may be needed during project peaks or test events.
