Position Overview
The Overall Principal Piping Engineer acts as the technical authority for piping layout engineering, pipe routing, isometric and support inputs, tie-in coordination, constructability review, and vendor/interface issue resolution for FPSO, FLNG, fixed platform, offshore renewable, onshore power, petrochemical, LNG, hydrogen/ammonia, CCS, and other complex plant projects. This role contributes to safe, constructible, compliant, and cost-effective project delivery by defining technical requirements, verifying calculations/specifications, resolving technical queries, and safeguarding design integrity.
The position works in a multidisciplinary FEED/EPCI environment with engineering, procurement, vendors, fabrication yards, construction, commissioning, and project management teams. The role makes or endorses discipline-level technical decisions for complex or high-risk issues, strengthens engineering standards, and mentors project teams across multiple work scopes.
The position supports model-based delivery, piping integrity, constructability, and field readiness by coordinating layout, materials, site interfaces, 3D model quality, drawing extraction, and issue resolution across engineering, procurement, fabrication, construction, and commissioning phases. It is expected to maintain strong interface control with process, mechanical, structure, E&I, vendor, and site teams to secure timely and practical outcomes.
Key Responsibility
- Establish and endorse piping layout engineering, pipe routing, isometric and support inputs, tie-in coordination, constructability review, and vendor/interface issue resolution in accordance with project specifications, client requirements, class/regulatory expectations, international codes, and company standards.
- Prepare, update, check, or coordinate piping layouts, pipe routing studies, isometrics, support inputs, tie-in lists, technical query responses, vendor document comments, and design review close-out records, ensuring accuracy, revision traceability, constructability, and timely issue for project milestones.
- Define or verify technical requirements, calculations, design basis assumptions, specifications, technical requisitions, vendor document comments, and technical query responses within the assigned discipline.
- Coordinate interfaces with process, mechanical, piping, electrical, instrumentation, structural, safety, procurement, construction, commissioning, vendors, subcontractors, and fabrication yards to close interdisciplinary issues.
- Support 30% / 60% / 90% design reviews, model reviews, layout reviews, constructability reviews, HAZOP/HAZID inputs where relevant, and client/vendor comment close-out.
- Identify constructability concerns, interface gaps, material or vendor data risks, schedule impacts, and management-of-change items; communicate mitigation actions clearly.
- Maintain engineering records, drawing/model data, review comments, calculations or registers, and as-built information in accordance with document control and quality procedures.
- Act as discipline technical/design authority for complex issues, approve or endorse critical solutions, strengthen work processes, and mentor engineers/designers across project teams.
Qualification
- Minimum 20 years’ experience in the offshore or onshore oil and gas industry
