ABOUT
Founded in Q4 2022, Sirona Subsea was formed with a clear vision to support the energy markets. We are currently operating out of 2-facilities in Darlington, UK. Darlington is situated in the North-East of England, which, is considered a UK Hub for the Oil, Gas and Renewable markets with excellent global transport links. Summer '25 marked the opening of our 17,000 sq ft facility - a major milestone that significantly enhances our operational capacity and positioned us for continued growth. This expansion allowed us to streamline workflows, scale production, and better serve our clients with increased efficiency.
We pride ourselves on being agile and responsive, with sensitivity to schedule requirements throughout the life cycle of our projects.
SUSTAINABILITY GOALS
The Sirona Subsea ESG strategy objectives are to align with UN Sustainable Development Goals. We can work with our clients to manage the carbon footprint of every project and reduce the environmental impact.
We conduct business with integrity and good governance, striving to improve year on year.

OUR MISSION
Building a
Sustainable Future
We are wholly committed to a sustainable future and reducing the impact that ocean plastic pollution is having on our environment, which is why we have committed to donating to the cause for every product we put in the water.
Ocean plastic accumulates in five ocean garbage patches, the largest one being the Great Pacific Garbage Patch. To solve it, we need to stop more plastic from flowing into the ocean, but also clean up what is already out there. If left to circulate, the plastic will impact our ecosystems, health, and economies for decades or even centuries.
With a long history in environmental protection products (leak-repair, environmental protection seals & decommissioning recovery tools), the team at Sirona Subsea, in conjunction with The Ocean Clean-up, are committed to minimising the environmental impact both us and our suppliers’ may have. We strive to optimise every design, minimising waste and pollution potential, whilst always looking to utilise recyclable materials. We are 100% committed to the removal of man-made products from the worlds seas.
