Excavator digging mud on Port Botany site

Port Botany LPG Terminal Demolition Early Works

Port Botany, NSW
Origin Energy
6 months
Completed 2022


Origin Energy engaged Liberty Industrial to complete the demolition and disposal of their LPG Facility and off-site pipeline and berth areas at Bulk Liquids Berth 1 (BLB1) located in Port Botany, NSW. The scope of works included the complete demolition, removal and disposal of all LPG storage and handling equipment including 18 LPG vessels known as ‘bullets’, along with any above-ground buildings and structures including off-site areas in the Pipeline Corridor and at Bulk Liquid Berth 1; disconnection and termination of utilities and services; removal of all materials, debris, waste and stored items from the site; and execution of all the necessary make good ground works for handover to the new site lessor, NSW Ports.


  • Site complexities included working amongst live infrastructure and consideration of an oil, fuel and gas pipeline corridor - which was owned by various stakeholders – that passed through the demolition zone. The corridor was required to be protected throughout the duration of the project.
  • All demolition works were to be carried out on reclaimed sand, which made for unstable ground conditions.
  • To make the site level, 30,000t of sand was to be removed within a tight 2-month timeframe.

Robust Solutions/Exceptional Outcomes

Robust solutions

  • Our team was tasked to remove Asbestos cathodic protection pipework that was 7 metres below FSL and 4 metres below the water table. To remove them without shoring and sheeting, which would have delayed the program by 4 weeks, the team mobilised a 120t crawler crane to over pile the asbestos pipes with a vibratory clamp and extract them.
  • A detailed traffic management plan was prepared for the movements of all vehicles. The project team worked highly collaboratively with the NSW Ports Authority to coordinate the movement of 20 trucks at any one time during the peak of the project.
  • Our team utilised a crane to dismantle the Marine Loading Arm (MLA) during a shutdown window of 5 days. It was then loaded onto a barge and transported to Origin Energy’s facility in Brisbane, Queensland.
  • An open communication channel was established with all stakeholders, which allowed for efficient and effective project management and stakeholder relations.


Exceptional outcomes

The project was completed to schedule and within budget. Origin Energy commended the project team for their efforts and successful project completion.
