Job description

Position Overview

The Senior Mechanical Engineer is responsible for leading and executing mechanical engineering activities for FPSO topsides and marine systems. This role covers design, specification, selection, integration, and assurance of mechanical packages and rotating/static equipment throughout FEED, EPC, and commissioning phases. The engineer ensures all mechanical deliverables meet project requirements, industry standards, and safety regulations.

Key Responsibilities

1. Engineering Design & Technical Assurance

• Develop and review mechanical engineering deliverables including specifications, datasheets, calculations, drawings, and technical reports.

• Lead mechanical design for rotating and static equipment such as compressors, pumps, turbines, heat exchangers, pressure vessels, separators, and utility packages.

• Ensure designs comply with project specifications, Class requirements, API/ASME/ISO standards, and regulatory codes.

• Perform equipment sizing, hydraulic calculations, thermal calculations, and mechanical integrity assessments.

2. Package Engineering & Vendor Management

• Prepare technical requisitions, evaluate vendor bids, and perform Technical Bid Evaluations (TBE).

• Review vendor documents, participate in design reviews (PDR, IDR, MDR, FAT, SAT).

• Provide technical support during package integration and interface resolution between disciplines and vendors.

• Ensure vendor data aligns with project documents, 3D model, and engineering schedule.

3. Project Execution & Coordination

• Coordinate mechanical engineering activities across disciplines (Process, Piping, Structural, Electrical, Instrumentation, HVAC, Marine).

• Support engineering managers in planning, scheduling, and progress reporting.

• Participate in HAZOP, HAZID, SIL, model reviews, constructability reviews, and risk assessments.

• Ensure mechanical designs consider operability, maintainability, reliability, and constructability.

4. FPSO Topsides & Marine Systems

• Provide engineering expertise for FPSO systems including:

  • Crude oil separation and treatment

  • Gas compression and treatment

  • Produced water treatment

  • Seawater lift & cooling medium systems

  • Utility systems (air, nitrogen, chemical injection, fuel gas, firewater, etc.)

  • Mechanical handling, lifting equipment, HVAC (as required)

• Ensure integration of mechanical packages with hull, turret, and marine systems.

5. Site Support & Commissioning

• Support yard engineering, construction, mechanical completion, pre-commissioning, and commissioning activities.

• Review method statements, installation procedures, punch lists, and resolve site technical queries.

• Participate in factory/site acceptance tests when required.

6. Quality, Safety & Compliance

• Ensure engineering deliverables meet quality standards and project KPIs.

• Promote safe engineering design that meets Class and regulatory requirements.

• Manage management-of-change (MOC) activities and ensure traceability.

Qualifications & Experience

Education

• Bachelor’s Degree in Mechanical Engineering or related discipline.
