DNV GL and ZephIR Lidar have signed a framework agreement which allows customers to request a ‘DNV GL Independent Quality Report’ in addition to the standard Performance Verification provided with all new systems.
Ian Locker, MD at ZephIR Lidar, said: “This framework agreement gives the industry further confidence, if required, that ZephIR 300 can be trusted to deliver accurate, IEC CD 61400-12-1 Ed.2, Annex L compliant and traceable results.”
DNV GL considers ZephIR 300 to be at Stage 3 under “benign” conditions – accepted for use in bankable / finance-grade wind speed and energy assessments with either no or limited on-site met mast comparisons. ZephIR was the first commercial wind lidar system to achieve accreditation at this level, the company pointed out.
ZephIR 300 measures wind characteristics onshore and on fixed or floating platforms offshore from 10 metres (33 feet) up to 200 metres (656 feet) above the installed position to inform wind regime and quality studies during the development and operation of wind farms onshore and offshore.
