Lead Testing & Commissioning Engineer - Offshore Platform

Job Description

1. Position Purpose

The Lead Testing & Commissioning Engineer shall lead the complete pre-commissioning, commissioning, start-up, performance testing and handover of the Project. The primary process package is the instrument air and plant air compressor system; however, successful commissioning depends on extensive integration with electrical power systems, instrumentation, package PLC, DCS/ESD/F&G, mechanical and piping systems, utilities, brownfield tie-ins and offshore operations. The role is therefore multidisciplinary and shall coordinate all relevant disciplines, OEMs, subcontractors and Company representatives to achieve safe and timely system start-up.
