Demonstration of anti-corrosion solutions in offshore renewable energy

In a previous blog post we discussed how corrosion of offshore renewable energy (ORE) devices comes at a high cost. The European project NeSSIE, in which Sirris is a partner, wants to tackle the problem of corrosion in the ORE sector by creating an opportunity to demonstrate anti-corrosion solutions.

In the first stage of the NeSSIE Competition three project developers were selected: Simec Atlantis Energy, Scottish and Southern Energy (SSE) and the European Marine Energy Centre (EMEC). In a second stage of the competition, NeSSIE is now looking for anti-corrosion solutions in a wide range of fields, including coating systems and application techniques, prevention of fouling, repair solutions, inspection and monitoring techniques, cathodic protection and design optimisation.

Commercial solution for projects

The second stage of the NeSSIE Competition invites offshore renewable supply chain companies to put forward commercial solutions for the projects and companies outlined in stage one.

In summary, the project developers are looking for the following specific solutions:

EMEC focusses on floating technologies (wave and tidal) which are highly exposed to oxygenated environments and have limited access for O&M operations. Specific challenges include bio-fouling, anti-corrosion coatings for aggressive splash zone and coatings for connectors.
SSE focuses on innovations in corrosion management and remediation for offshore wind farms. Specific (repair) challenges include the boat landing fenders, general TP corrosion remediation and hook-on points for personnel which require frequent repairs (problems with high salinity).
Atlantis focuses on the development of tidal turbines. Particular challenges include problems with recoating flanged joints which need to be opened for maintenance, flow effects on cathodic protection and cathodic disbondment on carbon fibre tidal blades.


In order to join the project and have a chance to be selected by the project developers to work with them, all interested solution providers are invited to sign in on an Expression of Interest (EoI), available on the NeSSIE webpage. There is no deadline for admission, but EoIs received after 30 November will not be considered for one-on-one meetings with the project developers during the NeSSIE conference in Glasgow on 24 January.

Once stage two is complete, the NeSSIE project partners will work with the project developers to develop business cases for each demonstration project and will help to identify potential funding packages to deliver them.

A webinar was held on 13 November, to give more information on the identified corrosion challenges and how solution providers can join the demonstration phase of the NeSSIE project. A recording of the webinar will soon be available on the NeSSIE webpage.
