Role Overview We are seeking an experienced Sub-Sea Structural Design Engineer to join a major Oil & Gas EPC project team. The successful candidate will lead and execute structural analysis and design of subsea assets — manifolds, PLETs/ILTs, flowlines mitigation devices, and foundation structures — using advanced FEM tools (ANSYS and/or Abaqus, and SACS). This role spans the full project lifecycle from FEED through detailed design to installation support.
Key Responsibilities
• Develop and validate FEM models (ANSYS Mechanical / APDL / Abaqus) for subsea structures; perform static, non-linear, fatigue (S-N / fracture mechanics), and buckling analyses.
• Execute ULS, FLS, ALS, and SLS checks per applicable offshore codes (DNV, API, ISO, NORSOK, Eurocode 3).
• Structural design and sizing of subsea steel — manifolds, mudmat foundations, spool supports, suction piles, and tie-in structures.
• Perform lifting, load-out, sea-fastening, and installation analyses; design lifting pad-eyes and rigging arrangements.
• Conduct piping design assessments; integrate with structural global analyses (SACS, SESAM, CAESAR II) as well as forged pieces design (Abaqus)
• Prepare, check,
and approve structural calculation packages, engineering reports, and IFC deliverables.
• Interface with installation method, pipeline, naval architecture, geotechnical, and process disciplines within multi-discipline EPC teams.
• Mentor junior engineers and support client design reviews, ,. Qualifications & Experience
