HMAS Stirling DFI Remediation

Package 2

Design Engineering(as “WILKIE) were commissioned by Decmil Australia Pty Ltd to provide their design and detailing expertise for the upgrade at HMAS Stirling DFI Remediation Naval Base.

There were multiple upgrades required for the facility, a few include, replacing the Navel Fuel installation pipelines and Oil Fuel Installation above group pipeworks to wharves and dump tanks.

HMAS Stirling DFI Remediation Service


As part of the Defence Fuel Installation (DFI) Remediation project at the HMAS Stirling Naval Base, an audit was performed and a number of Track Record items were raised for rectification. HMAS Stirling Naval Base DFI storage tanks and pipework were found to have non compliances to Defence Bulk Fuel Installation Maintenance Instruction (BFIMI) and AS1940 – 2004. Several upgrades to the naval base were required to bring it up to current standards. Design was contacted by Decmil to provide engineering design and detailing services for the project.

Project Objectives

The upgrades to the facility included replacing the Naval Fuel Installation pipelines and Oil Fuel Installation above ground pipework to wharves and dump tanks.


Design had to provide value engineering and cost engineering in the design to achieve the most cost effective solution for the works. Design also had to work within the hazardous areas which made the project very challenging.

Our Approach

Based on the scope of works and client specifications, Design developed preliminary design and general arrangement layout drawings of the terminal which included a proposal for the hardstand. Upon approval of the drawings,
Design began finalising the engineering design and produced engineering design drawings.

Design engineers were regularly involved in technical meetings with the client and provided weekly project status reports updating the client on budgets, timeframe and deliverables. Designs were required to comply with all the relevant regulatory and Australian Standards.
