SUPRAMECA has developed an innovative underwater pyrotechnic fixing technology for the offshore wind industry.
Suprameca’s innovative technology safely solves the problem of grounding sacrificial anode cages used to protect the submerged portion of steel piles in offshore wind turbines from corrosion.
These earthing operations are traditionally carried out by professional divers using underwater welding techniques, often in challenging conditions such as deep water and harsh weather. However, these methods can pose significant safety risks and have resulted in numerous diving accidents at various wind projects.
To avoid these risks, offshore wind developers are increasingly turning to alternative techniques that do not require human intervention.
Suprameca’s technology addresses this need by providing remotely operated and ROV friendly fastening tools. This positioning allows the company to capitalise on the rapidly growing market for safer and more efficient methods of grounding sacrificial anode cages in offshore wind projects.
Key features and benefits
- No diver required solution
- Significant time savings compared to hyperbaric welding
- Immediately operational
- Reliable and repeatable performance, regardless of operator skill level
- Optimal for cathodic protection (electrical connection resistance lower than 250 micro-ohms)
- Mechanical strength of assemblies up to 40 kN tensile force
Suprameca has extensive experience in the design, development and manufacture of bespoke equipment that meets high safety and reliability requirements.
