DNV GL aims to further enhance wind turbine reliability

Sep 30, 2014 - Norwegian testing and advisory firm DNV GL on Monday unveiled a new Joint Industry Project (JIP) that will seek to boost wind turbine reliability and lower equipment operating and maintenance (O&M) costs.

Via the initiative, which will be launched at the start of 2015, the company will aim to develop a “safe and reliable calculation concept” that will increase the reliability of wind turbines in extreme weather conditions, during heavy load periods and operation at remote locations. For that purpose, DNV GL will collaborate with stakeholders from various industries to jointly reduce damages in the field, as well as lower operation and turbine maintenance costs in the future.

The JIP is expected to be completed at the end of 2016. Subsequently, the gathered information will be incorporated in a DNV GL recommended practice or standard.

“By developing a reliable calculation concept for slewing bearings, energy stakeholders will be able to work towards realistic operational lifetime estimations, “ DNV GL said.

Last week, DNV GL said it had identified 14 cost reduction efforts that will allow the offshore wind sector to cut its cost of energy by as many as 25%. These include attempts to reduce subsea cable installation risks; ensure safe and effective application of high-voltage, direct current (HVDC) technology; optimise monopile design standards; help move jacket fabrication towards serial production; and help speed up the commercialisation of floating offshore wind technology, among others.
