New Reports Address Offshore Corrosion

Thursday, February 8, 2018

Two reports commissioned by the NeSSIE project, an endeavor geared toward developing offshore renewables demonstration projects related to corrosion issues, investigated the economic potential of anticorrosion solutions and the development of new materials, with results indicating money could both be saved and earned by addressing these issues.

According to NeSSIE, developers could save up to 84 billion euros ($103 billion) and create up to 82 billion euros ($100 billion) in supply chain opportunities.

Report Findings

For developers working on tidal and energy products in the EU, 16 billion euros could be saved by 2050, with over 68 billion euros potentially being saved for those working on offshore wind projects.

In terms of the anti-corrosion supply chain, the wave and tidal energy markets could lead to 25 billion euros in projects in EU by 2050, with over 57 billion euros going toward offshore wind projects.

Two reports commissioned by the NeSSIE project, an endeavor geared toward developing offshore renewables demonstration projects related to corrosion issues, investigated the economic potential of anticorrosion solutions and the development of new materials, with results indicating money could both be saved and earned by addressing these issues.

"This type of information is critical to get the wider value chain engaged and this report presents a significant opportunity for the EU’s world-class subsea value chain to develop products and services leading to high value job creation,” said economic report leader Henry Jeffery, of the University of Pittsburgh.

Basic Findings

While the assessment of economic opportunity is only meant to serve as a synopsis, and not an in-depth study, the study on materials and solutions found that:

  • Renewables-based electricity generation is expected to triple from 2013 to 2040, overtaking coal to become the largest source of electricity;
  • Cleaning of substrates before coating application is still a fundamental step, as it strongly influences the adhesion of protective coatings to the substrate; and
  • More and more offshore structures are being made of special alloys including high-strength steel, among others, but lower-strength and unalloyed steel must always be protected because of inherent low corrosion resistance.

“It’s clear from this early work that there are a wide range of technical solutions that can be deployed to great effect in the offshore renewables sector," said Stefano Valentini, NeSSIE ASTER Project Manager. "The EU supply chain is at the forefront of subsea excellence and we are confident this will bring forth excellent solutions that will see the cost of energy coming down in offshore renewables.”

The surveys were part of NeSSIE’s endeavors to develop three offshore demonstration projects relating to corrosion issues, while also accelerating the deployment and cost reduction of wave, tidal and offshore wind structures. NeSSIE also strives to impact the North Sea Basin economy significantly.

It would seem that this need for cathodic protection in this environment would lend itself perfectly to Metalizing with zinc during the manufacturing process. With bond strength easily reaching 1500 to 1800 psi, less expensive substrates could be used yet still maintain structural integrity for many years.
