Offshore Underwater Fixing Tools
SUPRAMECA has developed an innovative underwater pyrotechnic fixing technology for the offshore wind industry.
Description
Suprameca has developed innovative underwater fastening technology that provides a safe and efficient solution for grounding sacrificial anode cages used to protect the submerged sections of steel piles in offshore wind turbines against corrosion.
Traditionally, these earthing operations have been performed by professional divers using underwater welding techniques, often in difficult conditions such as deep water and adverse weather. These methods not only involve high costs but also pose significant safety risks, with numerous diving accidents reported on offshore wind projects worldwide.
To eliminate these risks, offshore wind developers are increasingly adopting alternative techniques that minimise or eliminate the need for diver intervention.
Suprameca’s technology directly addresses this challenge by offering remotely operated, ROV-compatible fastening tools. This approach enhances safety, reliability and efficiency, while positioning Suprameca at the forefront of the rapidly expanding market for safer, cost-effective and high-performance anode grounding solutions in offshore wind projects.
