A new Joint working group (JWG6) have been created between two technical committees (TC) of ISO.
The two technical committees are:
ISO TC 107: Metallisation and inorganic coatings (project lead)
ISO TC 35—organic coating, but also
ISO TC 156 WG10 (cathodic protection) as a liaison partner to the JWG6
Five projects have been approved, and five draft documents circulated:
25249-1 Corrosion protection of offshore wind structures, design considerations
25249-2 Corrosion protection of offshore wind structures, primary steel components—general requirements for thermal spraying and painting
25249-3 Corrosion protection of offshore wind structures, primary steel components—supplementary requirements for foundations
25249-4 Corrosion protection of offshore wind structures, primary steel components—supplementary requirements for towers
25249-5 Corrosion protection of offshore wind structures, Supplementary requirements for primary structural steel components—structural steel and cast components for nacelles
They are planning for 5 more for secondary steel components, qualification of metallisation and paint systems, repair of surface protection systems, composite structures, and last but not least, environmental impact considerations, including life cycle assessment (LCA).
Offshore wind was born in Denmark in 1992 with the project Vindeby, and therefore it has only been natural that the project initiative comes from Danish Standards and the offshore wind industry here.
ISO support industrial needs and offshore wind is a global industry. The standardisation works will be truly international, with already the following countries supporting the work and the joint working group: Australia, China, Czech Republic, Denmark, Ethiopia, Finland, France, Germany, Ghana, Iran, Italy, Japan, Jordan, Korea, Netherlands, Norway, Poland, Portugal, Russian federation, Spain, Sweden, Switzerland, United Kingdom.
The purpose of the NWIPs is to have overall industry-based ISO standard for the corrosion protection of offshore wind turbine structures to enable these structures to reach their intended service life.
