Ausdecom’s Contracting Strategy

The table below provides an overview of the main differences (and similarities) and where Ausdecom is positioned to manage the onshore disposal phase depending on whether the project is a fixed structure, a subsea installation, or a floating asset:


Contracting strategies and supply chain integration reduces risk, generates predictability, provides HSEQ harmony, and reduces cost. In addition, the knowledge gained from collaboration leads to long term improvements for all stake holders involved.
Ausdecom’s market position compliments our demonstratable in-house project management and operational delivery of complex onshore decommissioning projects. This provides Tier 1 contractors, supply chain partners, and regulators with the confidence that we can self-deliver the onshore disposal services in compliance with all applicable legislation, efficiently and with certainty.

Ausdecom appreciated that proximity to field along with marine access, water depth, quayside and laydown space are key determinants in positioning of an onshore disposal yard for offshore oil and gas asset dismantling and recycling. Ausdecom is promoting a strategic collaborative approach with facility land owners in all the existing Australia wide offshore supply base and servicing locations.
