Rig demolishing a section of the Clyde Oil Refinery

Clyde Oil Refinery Demolition and Removal

Location
Clyde, NSW
Client
Shell/Viva Energy
Duration
20 months
Status
Completed 2016

Overview

Shell Australia and Viva Energy Australia commissioned Liberty Industrial for the demolition and removal of all redundant refinery infrastructure at the former Clyde Refinery including refinery processing units, plant and pipework, chimney stacks, storage tanks and buildings, as well as the removal of significant amount of friable and bonded asbestos.

Challenges

  • The Refinery was identified as State Significant Infrastructure.
  • Works were conducted in an operational oil terminal facility.
  • The scale and size of the chimneys required personnel to work up to 14 storeys high to set up scaffolding and fix polythene sheeting.

Robust Solutions/Exceptional Outcomes

Robust solutions

  • Extensive consultations with WorkCover NSW, Department of  Planning and Environment, the Environmental Protection Agency and Parramatta Local Council and assistance with preparation of documentation to obtain development consent from NSW Department of Planning and Environment.
  • Meticulous planning and use of 3D modelling simulation software.
  • Comprehensive inspection to identify hydrocarbon associated hazards in order to develop risk mitigation strategies and implement adequate control measures.
  • Construction of a framework on which Liberty Industrial’s Asbestos Removal crew would follow up encapsulating the various columns and structures to create a negative pressure tent.
  • Application of innovative controlled wetting injection technology to remove friable asbestos safely and efficiently.
  • Use of a combination of techniques from traditional mechanical demolition, to oxy cutting, mechanically induced collapses and controlled explosives implosions.
  • Provision of state-of-the-art equipment.

 

Exceptional outcomes

The project was completed on budget, to schedule and without incident.

  • 500-tonne of hard set limpet asbestos was removed.
  • 1,640,000 litres of transformer oil including approximately 100,000 litres of Polychlorinated Biphenyl contaminated mineral oil was removed and recycled.
  • The 60m tall Platformer Reactor and 65m tall 1,500-tonne Reactor and Stripper structures were demolished.
  • Five 80-100m reinforced concrete chimney stacks were demolished through controlled use of explosives.
  • 93% of waste material was recycled with only 7% going to landfill.
