Pre Commissioning Engineer

We are seeking an experienced Pre-Commissioning Engineer to join our team for an upcoming marine pipeline project in Qatar. The ideal candidate will possess deep practical and technical engineering knowledge of pipeline integrity and pre-commissioning services, managing operations from initial flooding and cleaning through to final nitrogen purging before the asset goes live.

Key Responsibilities

• Pre-Commissioning Operations: Plan, engineering-supervise, and execute full-sequence pipeline pre-commissioning activities, including cleaning, gauging, hydrotesting, dewatering, drying, and nitrogen purging.
• Procedure Development: Prepare and review detailed engineering method statements, calculation sheets, risk assessments (HIRA), and operational procedures for subsea/onshore pipeline integrity services.
• Hydrotesting & Pressurization: Oversee hydrostatic strength and leak testing, ensuring accurate pressure monitoring, hold periods, and compliance with international standards (e.g., ASME, API).
• Drying & Purging: Supervise advanced pipeline drying techniques (such as air vacuum drying, chemical swabbing, or desiccant drying) and manage high-pressure nitrogen purging/blanketing operations.
• Equipment Management: Coordinate the mobilization, setup, and operation of specialized pre-commissioning equipment, including high-flow filling pumps, high-pressure test pumps, air compressors, vacuum spreads, and nitrogen generation units.
• Data & Instrumentation: Monitor and verify data from engineering instrumentation (deadweight testers, temperature charts, flow meters) to ensure precise execution and reporting.
• QA/QC & Documentation: Compile comprehensive final pre-commissioning data books, engineering reports, and certification packages for client approval.
• HSE Compliance: Enforce strict safety protocols specific to high-pressure testing, hazardous gas handling, and marine/offshore operations.

Qualifications & Experience

• Education: Bachelor’s degree in Mechanical, Chemical, Petroleum, or Civil Engineering.
• Experience: Minimum 5+ years of direct experience as a Pre-Commissioning Engineer in pipeline or marine infrastructure projects.
• Project Location: Previous experience working on oil & gas or marine projects in the GCC region (Qatar experience is highly advantageous).

Technical Expertise: Proven, hands-on engineering experience running the following operations:

• Pigging operations (Bi-di pigs, foam pigs, gauging plates).
• Hydrotesting and pipeline dewatering.
• Deep pipeline drying and dew-point verification.
• Nitrogen handling and purging protocols.
• Certifications: Valid offshore survival certificates (BOSIET/HUET) and a valid passport are preferred due to project mobilization requirements.
