Transforming Subsea Decommissioning
X-Lay™ cutting rigid pipeline removal costs by S$20B to 2040, with reduced environmental impacts
The Decommissioning
Challenge
Global subsea infrastructure is entering large-scale decommissioning. The total subsea pipeline network is >150,000km long. Removal from the ocean is the only pathway that eliminates biohazards and enables recycling, but traditional removal solutions are very expensive and taxpayers fund up to 70% of these costs.
Traditional pipeline removal solutions involve either the reverse of the original method or subsea cut and lift. These methods are capital-heavy and productivity constrained.
The Centre of Offshore Decommissioning Australia is forecasting that >1,200km of rigid subsea pipelines will require complete removal by circa 2030. Australian taxpayers must currently contribute up to 40% of these future costs.
Offshore Energies UK is forecasting >3,000 km of rigid subsea pipelines will be decommissioned from 2025 to 2034. This is split between the Netherlands (46%), UK (28%) & Norway (26%). UK taxpayers must currently contribute up to 70% of these future costs.
Unlike Australia, it is much less clear if & when the complete removal of these, plus previously decommissioned or suspended pipelines may be required in future.
Removal costs for rigid pipelines in Australia run to billions of dollars and can only increase with traditional solutions. We estimate that X-Lay™ can reduce these costs by >50%.
This makes X-Lay™ a very attractive proposition for Australian & European Governments to co-invest in further R&D efforts and for Energy Operators to co-invest in Feasibility Studies.
Our Commercial Model
We are focused on creating value for our Operator and Subsea Contractor clients in 4 segments: i) engineering services, ii) licensing X-Lay™, iii) developing additional licensable technologies & iv) developing next generation solutions
Subsea Facilities Integrity & Removal Engineering
Expertise in the analysis of subsea facilities integrity and efficient removal engineering. Our consulting services encompass from Concept, FEED, through to Detailed Engineering.
X-Lay™
X-Lay™ is our flagship technology we plan to license to Subsea Contractors, enabling the removal of pipelines with >> 50% cost savings relative to the status quo, while achieving superior environmental outcomes.
Blue-Sky Solutions
Leveraging our unique innovation engine , we are seeking global partners aligned with our vision to jointly develop additional licensable technologies to enable the transformation of subsea and offshore facilities removal.
Faster, Smarter Subsea Decommissioning
Our technologies and operating intelligence combine to create faster, lower-cost and repeatable routes to transform subsea decommissioning, reduce reliance on in-situ disposal, and return offshore materials into circular use.
Innovation Pipeline
Beyond X-Lay™, Restore Subsea is committed to developing a portfolio of proprietary technologies (Blue-Sky Solutions), with the support of our AI-Native Operating system that could significantly contribute to the acceleration of subsea facilities and biohazard removal, enabling increased downstream recycling and responsible subsea restoration.

A brief overview of our proposed X-Lay™ solution applied to the Australian market in circa 2030.
Progressing Toward Commercial Deployment of X-Lay™
We commenced our “Technology Demonstrator Phase” for X-Lay™ technology in 2020, and following a Seed Raise in 2025, we moved into our “Commercial Demonstrator Phase”. This phase currently involves independent technology qualification via DNV-RP-A203, further R&D, engineering, and potential pipeline bend analysis/testing, all crucial for our efforts to pre-qualify X-Lay™. We are also seeking Government Grant funding and consideration from Energy Operators to support our various initiatives.
We plan to be DNV “Technology Qualified” in late Q4 2026 and our Series A Raise in early Q1 2027 will support our Growth Phase as we pre-qualify our proprietary offerings for various use cases, preparing for Invitations to Bid (ITB) to Subsea Contractors for upcoming subsea pipeline removal projects worldwide.
We will strengthen our niche-focused IP with advanced pipeline strain management, alongside further R&D and lab testing of various pipeline types and sizes.
