Role Summary

The Subsea Pipeline Engineer is responsible for the engineering design, verification, installation planning, and operational assurance of subsea pipelines in shallow-water environments. The role ensures technical integrity, compliance with project specifications, safe installation, and interface coordination with structures, subsea production equipment, and offshore construction teams.

Engineering Design & Technical Review

• Perform and review design calculations for pipeline wall thickness, on-bottom stability, free-span assessment, corrosion protection, and burial requirements.
• Review pipeline routing, tie-in configurations, expansion control, and pipeline crossing designs.
• Conduct design verification and ensure compliance with DNV-ST-F101, API, ISO, and project-specific standards.
• Review pipeline materials selection, coating systems, and cathodic protection principles.

Shallow-Water Installation Engineering

• Prepare and review installation procedures for pipe laying (S-lay/barge), shore approach, trenching, jetting, and burial.
• Evaluate environmental conditions and their impact on installation.
• Interface with marine operations teams for vessel readiness and operational limits.

Interface & Coordination

• Coordinate with subsea structures, riser teams, and topsides engineering.
• Provide technical clarification to fabrication and installation contractors.
• Participate in HAZID, HAZOP, and constructability reviews.

Offshore Support

• Conduct offshore surveys, route verification, and as-built data review.
• Provide engineering support during laying, trenching, repairs, and pre-commissioning.
• Prepare daily offshore engineering reports.

Documentation & Deliverables

• Develop design reports, specifications, data sheets, and method statements.
• Review drawings: P&IDs, alignment sheets, isometrics, spools.
• Handle technical queries and contractor documentation.

Project Management & QA/QC

• Monitor contractor progress and quality.
• Participate in FAT, SIT, and material inspection.
• Ensure safety and environmental compliance.

Key Competencies

• Strong knowledge of subsea pipeline design and DNV/ISO standards.
• Understanding of shallow-water installation challenges.
• Ability to review FE modeling (OrcaFlex, PipeLay, Caesar II).

Strong interface management and offshore experience
