The Subsea Pipeline Installation Engineer is responsible for engineering, planning, and executing the safe and efficient installation of subsea pipelines in shallow-water offshore environments. The role includes installation method development, marine spread engineering, analysis, offshore support, and multi-discipline coordination.
Installation Engineering & Method Development
Develop installation methodologies for S-lay/barge lay, shore approach, tie-in spools, and jumpers.
Perform engineering calculations: catenary, tension, M  control, stress/strain, on-bottom stability.
Review metocean limits and operational weather windows.
Prepare trenching, jetting, and burial methods.
Offshore Execution Support
Support offshore mobilization, deck setup, welding spread arrangement.
Monitor real-time installation parameters (tension, layback, speed).
Coordinate with vessel crew, ROV, and survey teams.
Resolve offshore engineering issues during operations.
Installation Procedures & Documentation
Prepare installation procedures, work packs, method statements.
Develop risk assessments, lifting plans, and touchdown monitoring procedures.
Review contractor procedures for compliance with project requirements.
Interface & Coordination
Interface with pipeline design for M , loads, coating and free-span limits.
Interface with subsea structures for tie-in, lifting, and handling requirements.
Interface with umbilical/FOC and controls teams for routing and combined lay.
Interface with marine and survey teams for UXO clearance, route verification, and as-built surveys.
Marine Spread Selection & Planning
Support selection of lay barges, anchor spreads, and marine support vessels.
Review stinger/roller setups and tensioner capability.
Plan shallow-water anchor patterns and vessel maneuvering constraints.
Trenching, Protection & Post-Lay Activities
Review trenching/jetting/ploughing techniques.
Plan pipeline protection (mattresses, rock dumping).
Support post-lay survey review and free-span remediation.
HSE & Risk Management
Participate in HAZID/HAZOP and constructability workshops.
Develop SIMOPS plans for marine operations.
Ensure all installation activities comply with HSE and marine assurance requirements.
Technical Requirements
Knowledge of pipeline installation engineering: catenary, M , stability, tension control.
Understanding of shallow-water constraints and surf-zone challenges.
Proficiency with Orca Flex, Pipe Lay, Offpipe, MathCAD, and route planning tools.
Knowledge of pipeline materials, coatings, buckle arrestors, and field joints.
Familiarity with trenching, protection, and tie-in systems.
Qualifications & Experience
Bachelor’s degree in Mechanical, Marine, Offshore, or related Engineering.
8–10 years’ experience in subsea pipeline installation engineering.
Experience in shallow-water S-lay/barge lay operations.
Offshore installation support experience preferred.
Knowledge of DNV-ST-F101, DNV-RP-F109, API RP 1111 standards.
