Lloyd’s Register is a recognised world leader in the provision of Independent Certification and Verification services to the offshore wind power and oil & gas industries and it can draw on decades of experience to increase the safety and reliability of offshore wind projects. We help our clients minimise risk at every point of their projects, from design all the way to installation and commissioning.

Project certification provides the required confidence and assurance that your offshore wind projects are in compliance with project requirements, applicable industry codes and standards and national requirements.

What we offer

We offer Project Certification services in accordance with IECRE OD-502 or IEC/EN 61400-22, which are internationally recognised as the certification standard for windfarms, supported by the applicable codes and standards.
These set out the key requirements for design, manufacture, transport and installation, commissioning, operations and maintenance of windfarm assets.

The services can be expanded to also ensure that your windfarm assets meet relevant country-specific requirements and incorporate any additional requested requirements for certification.

Our personnel cast an impartial and expert eye during the execution of these services to ensure compliance with the applicable requirements and to provide the required assurance and risk mitigation for a successful project
