Asset Monitoring – Corrosion Prevention

Proserv specialises in the delivery of standard products and the design and manufacture of bespoke corrosion solutions to enhance field safety and increase production levels both topside & subsea and onshore and offshore.

Subsea Corrosion Monitoring & Anode Retrofit

A growing proportion of our global subsea infrastructure and platforms are reaching the end of their intended design life – some have already exceeded design life. Combine this with the challenges we currently face as an industry and you realise there is a need to look and behave differently from what we are used to. We need to collaborate to deliver more for less. We need to work together earlier.

Asset integrity can only be achieved effectively if we have the right data and information to make informed decisions. Too often we take action based on poor data because we’re scared of what might happen; this is the harsh reality that faces every asset manager. In parallel, there is a drive to delay action and reduce costs.

Solutions that can improve knowledge on the true integrity of assets are enablers for getting the timing right for the right action. This is critical if, as an industry, we are to remain competitive and meet the challenge of reducing costs.

Proserv’s leading approach is to develop the installation methodology first and cathodic protection design second.

A New Approach

Proserv has developed an innovative suite of technologies to improve data quality on subsea corrosion monitoring, simplifying the decision making process and reducing risk. Proserv’s data can prove that, despite visual and ROV probe inspection, the asset is protected and will reach the required design life. Should action in the form of anode retrofit be required, Proserv’s leading approach is to develop the installation methodology first and cathodic protection design second. Adopting this approach with unique technologies, such as friction welding with ROVs, is creating a step-change in the industry as Proserv continues to partner with clients to develop the right solution.


With Proserv’s acoustic subsea monitoring and control technology (NASCoM), data relating to the corrosion and protection status of assets can be recovered without having ROVs or divers in the water. Not only does this enable data to be recovered at a much greater frequency than before but the cost of doing so is significantly reduced.

Through Proserv’s NASCoM technology, the data is also better quality as the monitors are at fixed permanent locations meaning that errors are less prevalent and trending over time is significantly more accurate.

Friction Welding

Proserv’s Friction Welding (FW) technology provides the ability to retrofit galvanic anodes with ROVs to platforms, FPSOs, pipelines and subsea structures. This innovative technical solution offers asset owners a new alternative to impressed current cathodic protection (ICCP) systems and clamps fitted by divers. The same solution is also used to attach acoustic corrosion monitors that not only enable the condition of the asset to be known, they also provide data on the performance ofthe retrofitted anode system.

Friction Welding has a strong proven track record and has become an essential part of many asset owners’ corrosion and integrity management programmes.
