Kingfish Offshore Project Delivery Team

Overview

Preparing offshore infrastructure for decommissioning demands precise planning, flawless execution, and an uncompromising focus on safety. Supporting UGL Pty Ltd on behalf of Esso Australia, EnerMech delivered a critical pipeline flushing campaign across four offshore assets in the Gippsland Basin. Through integrated project management, engineering expertise, and coordinated offshore execution, the team completed all activities safely, on schedule, and without equipment downtime—helping to advance one of Australia's largest offshore decommissioning programs and securing follow-on work for the next phase of the campaign.

Key Highlights:

  • Successfully delivered pipeline flushing and cleaning operations across four offshore platforms: MLA, WKF, KFA, and KFB.

  • Completed a critical-path scope in line with the overall decommissioning schedule.

  • Achieved zero injuries, environmental incidents, or unplanned releases throughout execution.

  • Maintained continuous offshore operations with no equipment downtime impacting delivery.

  • Coordinated engineering, logistics, mobilization, and execution activities under accelerated delivery timelines.

  • Supported the wider decommissioning program through integrated working.
