Darwin Pipeline Duplication (DPD) Project at the Darwin Liquefied Natural Gas (DLNG) Facility
2024-2025
Location: NT
Client: Santos / NACAP
Sector: Energy
As a trusted supplier, WPF Duratec were engaged by Santos to deliver on a high risk / critical path project.
The challenge was to fabricate 50T of structural steel concurrently with 250T of pipe spooling in a small-time window. WPF were requested to accelerate the delivery schedule and reacted accordingly, by utilising 2x workshop locations (NT & WA) running around the clock shifts to ensure tight schedules could be met. The request then came through to assist in the installation of the piping tie-ins and WPF Duratec successfully mobilised 80x personnel to Darwin including equipment within a 2x week window. The campaign was successful; schedule was achieved & we are proud of a 0% DNC site rate and being LTI free.
- Concurrent night and day shift fabrication completed in Naval Base & Darwin workshops to ensure faster turnaround.
- Workshop fabrication consisting of welding, PWHT, NDT, hydrostatic testing and surface treatment.
- Successfully completed 15x AS2885 and 11x ASME B31.3 PQRs offsite
