Job summary

Saipem in India seeks an experienced Sub-Sea Structural Design Engineer to lead technical analysis and design of subsea assets—from manifolds to flowlines—using ANSYS, Abaqus, and SACS across FEED to detailed design.

The role requires delivering robust FEM models, meeting offshore codes, coordinating with multi-discipline teams, and mentoring junior engineers on complex subsea projects.

Qualifications

• BE/BTech or ME/MTech in Structural, Civil, Mechanical, or Ocean/Offshore Engineering.
• 5–15 years of structural engineering experience in Oil & Gas or offshore sectors.
• Proven ANSYS and/or Abaqus FEM delivery on subsea or offshore projects.
• Offshore safety certification (BOSIET/HUET) preferred/required for site access.

Responsibilities

• Develop and validate FEM models for subsea structures using ANSYS Mechanical / APDL / Abaqus and SACS.
• Perform static, nonlinear, fatigue (S-N / fracture mechanics), and buckling analyses per offshore codes (DNV, API, ISO, NORSOK, Eurocode 3).
• Design subsea steel structures: manifolds, mudmat foundations, spool supports, suction piles, and tie-in structures.
• Carry out lifting, load-out, sea-fastening, and installation analyses; design lifting pad-eyes and rigging.
• Coordinate with piping, naval architecture, geotechnical, and process disciplines within multi-discipline EPC teams.
• Prepare, check, and approve structural calculation packages, engineering reports, and IFC deliverables.
• Mentor junior engineers and support client design reviews.

Job description

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

• B.E./B.Tech or M.E./M.Tech in Structural, Civil, Mechanical, or Ocean/Offshore Engineering.
• 5–15 years in structural engineering within Oil & Gas, Offshore EPC, or Marine sectors.
• Demonstrated ANSYS and/or Abaqus FEM delivery on subsea or offshore structures.
• Deepwater project experience (>500 m) is a strong advantage.
• Chartered Engineer (CEng — IStructE / ICE / IMechE) preferred.
• BOSIET / HUET offshore safety certification (required for site/vessel access).
• Prior experience at Saipem, TechnipFMC, Subsea 7, McDermott, Aker Solutions, Oceaneering, Wood, or Worley is advantageous.
• Materials knowledge: CS, duplex/superduplex SS, CRA clad, Inconel alloys.
