Two firms team up to help turn aging rigs into reefs

Oil and gas engineering and consulting company Xodus has teamed up with stabilisation and artificial reef specialist Subcon International to help operators who decide to turn their retiring offshore assets to reefs.

The partnership has come up with what it calls the Integrated Rigs to ReefsTM (IR2RTM).

“Whilst the reefing of retiring offshore structures makes sense to many, such projects often struggle to address the regulatory hurdles, public perception and who takes the enduring liability for the asset. The Integrated Rigs to ReefsTM (IR2RTM) solution resolves the many challenges owners face by augmenting and integrating the retiring assets into purpose built reefs,” Xodus said on Thursday.

According to Xodus, the alliance combines Xodus’ decommissioning capabilities with Subcon’s extensive track record in the design and construction of purpose-built marine habitats.

Enrico Salardi, Xodus Group’s Director of Decommissioning said: “IR2RTM is a decommissioning solution which provides many benefits to oil and gas operators, governments, local industries, communities and ultimately to the environment. The IR2RTM solution delivers material cost savings to operators whilst enabling them to turn a legacy asset into a positive legacy for the environment.

“Importantly, this industry-first offering provides a clear pathway for the transfer of ownership to state agencies.”

Who’s responsible for the “reef”?

 

While the rigs to reef solution has a proven track record for generating decommissioning cost savings and for creating effective habitat, Xodus says, the question of who has enduring liability for the structure remains open.

The company explains that the IR2R model employs methods of relocation, augmentation and integration to completely reinvent the retired structures as productive, purpose built artificial reefs. Ownership and liability for the new asset is then able to be transferred to appropriate government agencies.

Subcon International CEO, Matthew Allen added: “Our collaboration with Xodus enables more operators to benefit from our innovative IR2RTM model. The creation of new, purpose built habitat through the integration and augmentation of retiring marine structures, means degraded habitats can be restored and new habitats established. It reduces costs for the operator, reduces waste onshore, and establishes a more vibrant and productive marine environment for future users. It is a true win-win for all stakeholders”.

According to the statement on Thursday, there is already one project underway utilizing the new solution. Offshore Energy Today has reached out to Xodus, seeking more info. We will update the article if we get a response.
