DNV and GL have signed an agreement to join forces. The new entity, called DNV GL Group, will be one of the world’s leading ship classification societies and risk experts in the renewable energy, oil and gas, power sectors, and among the global top three in management system certification. “Clients will benefit from an increased…
Fiberglass company gets GL approval for new reinforcements
3B-the fiberglass company has obtained Germanischer Lloyd (GL) approval for its recently developed SE2020 single-end rovings used mainly for manufacturing noncrimped fabrics in wind turbine blades. “Noncrimped fabrics from SE2020 rovings are suitable for resin infusion or prepreg processes and benefit from 3B’s innovative and proprietory sizing technology focused on specific resin families, in this case epoxy,”…
Consultants release wave-energy-conversion design software
At the International Conference on Ocean Energy (ICOE) in Dublin, GL Garrad Hassan has release WaveDyn, the first independently developed wave-energy converter design tool made commercially available. WaveDyn lets users model a range of wave energy conversion devices. The developer says its flexible, multi-body modelling approach, coupled with a hydrodynamic flow solver, and a range…
Plant controller earns GL certification
GL Renewables Certification (GL RC) has issued a component certificate to SCADA International for its power-plant controller. The GL RC certificate confirms that the power-plant controller meets the requirements of the Federation of German Windpower and other Renewable Energies. The certificate is the first issued to a power plant controller based on an assessment of…
Operating at extremes: tech note on turbine operation in cold climates
It’s no surprise that wind turbines are operating in areas where temperatures tests the machinery to its limits. Turbines are usually designed to operate in a temperature range from –10 to +40°C, but at some installations temperatures can drop to -40°C. To ensure that turbines work well in cold climates, GL Renewables Certification has issued…
Yaw brake earns GL certification
A yaw brake model, FHGE, comes in three models, -77, -90 and -120. Each features a small air gap and few moving parts for a short response times and fast braking. Additional features include a large brake-pad area and low brake-disc temperatures. For the wind-energy market, the company manufactures rotor brakes that generate braking forces…
