The Subsea Anode Repair Solution is developed to repair cathodic protection for submerged structures
Our advanced Anode Repair concept delivers highly cost-efficient and low-risk solutions for life extension purposes and repairs cathodic protection for submerged structures. This solution can save up to 75% in costs compared to the expensive alternative technical solutions and diving operations.
Our advanced concept can be adapted for any size and shape of anodes, whether the surface is mounted or welded, and offers a very fast anode exchange procedure, which avoids diver intervention and can be undertaken in extreme weather conditions. All is done according to certification from DNV GL.
We can provide the full offshore installation, or if preferred the basic setup for the installations.
We have developed a better solution for repairing degraded anodes on offshore structures, pipelines and foundations. Learn much more in the video.
The video shows a standard ROV equipped with a bespoken tool that picks up a new anode from a rack in the vicinity of the target. The ROV flies to the target, the tool adjusts to fit the actual orientation of the degraded anode, the ROV moves towards the target, the new anode is clamped on the supporting steel of the degraded anode, and then turns to retrieve the next anode to be installed. The process runs very efficiently and safely, and the actual clamping process takes around 5 minutes. This makes it a highly cost-efficient and low-risk solution.
Anodes including clamps can be fitted on all types of passive anodes
Specifically designed installation clamping tools for any ROV and anode type
Bespoken seabed installation clamping tools for the actual anodes
Can be adapted for any size and shape of the anode
This solution substitutes expensive alternative technical solutions and diving operations.
The anodes and clamps are designed for the most extreme conditions according to DNV GL for the North Sea area, in compliance with the codes: DNV-OS-C101, DNV-RP-C205, and DNV-RP-B401. Each type of clamp is tested for 10 years full-scale load cycles; corresponding to more than 36 million loads cycles.
The actual loads and electrical resistance are recorded and verified for each load. The electrical resistance is verified to be below 100 mΩ to confirm the mechanical and electrical functionality over a lifetime.
