Subsea Structure Engineer (Shallow-Water Offshore Project)

The Subsea Structure Engineer is responsible for the engineering design, structural verification, installation support, and integrity assurance of subsea structures for shallow-water offshore developments. These structures include manifolds, PLETs, PLEMs, jumpers, tie-in structures, pipeline supports, and foundations. The role ensures structural integrity, compliance with international standards, and seamless coordination with pipelines, controls, umbilicals, and installation teams.

Key Responsibilities

Engineering Design & Analysis

• Perform structural strength assessments, global/local analyses, and fatigue evaluations.
• Assess hydrodynamic loading conditions and soil-structure interaction.
• Review and validate FE models developed using ANSYS, Abaqus, SACS, and OrcaFlex.
• Ensure compliance with DNV, API 17D, API RP 2A, ISO 13628, and related industry standards.

Structural Layout & Deliverables

• Develop general arrangement (GA) drawings, structural layouts, mudmats, and foundations.
• Review and evaluate protection structures such as mattresses and rock dumping systems.
• Prepare and review interface drawings with pipeline, controls, and umbilical systems.

Installation Engineering Support

• Provide engineering input for lifting design, rigging, and offshore handling requirements.
• Review installation procedures for lowering, positioning, tie-in operations, and subsea deployment.
• Support offshore campaigns including load-out, transportation, and installation activities.

Interface & Coordination

• Coordinate closely with pipeline, subsea controls, umbilical, and geotechnical engineering teams.
• Support fabrication yards in welding, NDT, coating, and dimensional control activities.
• Participate in HAZID, HAZOP, constructability reviews, and 3D model review sessions.

Material & Fabrication Support

• Review welding procedures (WPS), qualification records (PQR), NDT plans, coating specifications, and fabrication tolerances.
• Support FAT and SIT related to structural components and interfaces.

Integrity & Operational Support

• Support in-service structural integrity assessments.
• Review ROV/Diver inspection reports, as-built documentation, and anomaly findings.
• Update structural models for life-of-field evaluations and reassessments.

Required Qualifications

• Bachelor’s degree in Mechanical, Civil/Structural Engineering, or Naval Architecture.
• Master’s degree in Offshore, Structural, or Ocean Engineering (preferred).
• 5-12 years of subsea/offshore structural engineering experience.
• Proficiency in ANSYS, Abaqus, SACS, or OrcaFlex.
• Strong understanding of API, DNV, and ISO standards.
• Offshore exposure (installation support, inspection, FAT/SIT) preferred.
• Strong communication, coordination, and problem-solving skills.
