⁠⁠⁠Scope of Work

Diesel Tanks Refurbishments – 2026 - 2031 - Blast and Paint ONLY

This EOI only covers the Blast and Paint part of the scope, itemised in the second paragraph.

This work encompasses a program of remediation, inspection, and upgrade activities across multiple diesel storage tanks at Paraburdoo (PBO), Parker Point (PPT), 7 Mile Dampier (7M), and Hope Downs 1 (HD1). Key requirements include the replacement of tank floors (typically 8mm thick, including sump and annular sections), application of protective floor coatings, and execution of API 653 inspections at scheduled outages. Many tanks also require the replacement of dewatering and product drain lines (40mm and 100mm), installation of new access platforms to valves, and repairs to shell and external coatings. At PPT, additional specialised works are needed, such as jacking tanks for annular/base repairs, addressing settlement and tilt issues, and managing hazardous external coatings. Several tanks have leak detection liners or risk-based exemptions that allow for deferred inspections, but these will require ongoing monitoring and reassessment. The program also calls for the replacement of critical valves, installation of tank davit arms, and rectification of external staircase corrosion. Outage windows are primarily concentrated between 2026 and 2028. Hot work restrictions are required at some sites and, in some cases, temporary repairs are required until full remediation can be executed.
