Decommissioning

Decommissioning and abandonment

Tetra Tech Coffey is committed to the responsible decommissioning of oil and gas infrastructure.

Our teams of specialists understand the complex aspects of decommissioning of oil and gas infrastructures, and our
experience in this highly specialised field enables us to consistently deliver against objectives in often complicated and
highly regulated environments.

As operations move towards their end-of-field-life, regulators and industry must work together to address the removal of
pipelines, platforms and other structures at sea. Tetra Tech Coffey’s team of specialists help our clients address the requirements of Australian and International regulators, with experience across subsea, topside, marine and maritime decommissioning and abandonment programs.

Our services cover all phases of the project lifecycle; from project management, planning and inspection, design and
engineering, to regulatory compliance, and approvals.

Our services include:

  • Safety case updates
  • Environment plans
  • Marine impact studies
  • Biosecurity assessments
  • Slops, bilge and flush water sampling, including realtime analysis
  • Solid and liquid waste management
  • NORM survey and management
  • Inventory of hazardous materials approved by
