Corrosion protection of offshore wind structures — Part 2: Primary steel components — general requirements for thermal spraying and painting

Scope

This standard specifies the general requirements to surface corrosion protection of structural members for offshore wind structurers for execution of the preparation-, and coating process on steel tower structures for off-shore wind in order to ensure adequate levels of durability of the following types of coating protective systems:
— metal material (e.g., Zn99,99, ZnAl15) based applied using thermal spraying and supplied in the state: as-sprayed, sealed, or with organic coating of e.g. type epoxy-, and polyurethane;
— based on paint products of e.g. type: zinc-rich-, epoxy-, and polyurethane.
related to be following topics:
— Execution specification of coating systems;
— Manufacturer’s documentation (Quality assurance system, quality plan etc.);
— Manufacturing process;
— Inspection, testing correction;
— As-built documentation
This standard may be required to be used in conjunction with one or more of the following Parts:
— Part 1: Design considerations;
— Part 3: Primary steel components - Supplementary requirements for Foundations;
— Part 4: Primary steel components - Supplementary requirements for Towers;
— Part 5: Supplementary requirements for primary structural steel- and cast components for rotor nacelle assembly;
NOTE
Typical the following components should be considered as offshore wind and related structures.
— Offshore steel foundation for wind turbine, substation and topsides
— Steel Tower sections
— Structural steel, cast iron or cast steel, and welded/bolted main components in the rotor-nacelle assembly.
