WEG are suppling two drive motors for the world’s most power ful test rig This test rig is being developed by Danish wind turbine test specialist, R&D Test Systems, a co m p a ny t h a t d eve l o p s p ro j e ct s a n d validates new technology with turnkey test systems With two 30 MW motors from WEG, the test rig will be the world’s most power ful power train and gearbox test bench and, at 60 metres long, will also be the largest

ZF Wind Power, an international technology group a n d m a r k e t l e a d e r i n d r i v e l i n e a n d c h a s s i s technology, is the final user of this test rig This 30 MW powertrain and gearbox test bench will be housed in ZF Wind Powers’s Test and Prototype Center in Lommel, Belgium The test rig is capable of simulating the multiplicity of wind loads that a nacelle powertrain might experience in its lifetime, helping to improve product reliability and shorten time to market

The test rig sees two nacelle components, for example two power trains or two gearboxes, tested simultaneously The two 30 MW motors are positioned on each end of the nacelle components under test, with an additional load unit located between the two components that simulates wind l o a d s c o m p a r a b l e t o r e a l - w o r l d c o n d i t i o n s Together, the motors and load unit can stimulate not only harsh wind loads, but also the effect of wind coming from different directions Marek Lukaszczyk, Europe and Middle East marketing manager for WEG, commented on the announcement: “WEG has extensive experience in supplying motors for renewable projects, so we are confident that our motors will help to ensure that this test rig operates at peak performance "Rigorously testing new technologies for renewable energy generation is essential for our planet's future The two motors from WEG will be delivered in October 2023, and the system will ultimately be delivered to ZF Wind Power in 2024 ”

Explaining the need for such a powerful system, Ralf Nieschler, Key Account Manager, R&D Test Systems said in the press release from R&D Test Systems, “The wind loads and directions can var y greatly, and each change creates loading on the nacelle powertrain This new test rig must be much m o r e p o w e r f u l t h a n t h e p o w e r t r a i n i t t e s t s , providing proof that the next generation of offshore turbines are capable of operating reliably in extreme offshore conditions over the defined lifetime

“The force of gusts of wind can push the blade a r o u n d T h i s t w i s t i n g a n d b e n d i n g o f t h e powertrain in all possible directions in the test rig will simulate the effect of 20 years of wind conditions, in just a few m o n t h s , ” c o n c l u d e d

Nor way -based Hagland Shipping has launched the second in a series of three new batt er y -hybrid bulker carriers being built by Dutch shipbuilding company Royal Bodewes.

Hagland initially signed a contract with the Dutch shipbuilder for two batter y-hybrid vessels however, the firm decided to purchase one additional 5,000 dwt bulk carrier in 2022

The company picked EST-Floattech’s batter y system which will enable the 5,000 dwt self-discharging bulker to make zero-emission por t calls

This batter y system enables the 5,000 dwt self-discharging bulker to action zeroemission por t calls

The vessel will also sail in full-electric mode thus being ready for environmentally sensitive environments such as in fjords or near-coastal communities When there is no shore connection available the batter y system also allows for zero-emission discharging of the transpor ted bulk cargo

The newbuild will not only sail in zero-emission mode in por t, but it will also reduce noise and emissions during sailing

These new coasters will reduce CO2 emissions by 40% and NOx emissions by about 90%, compared to older vessels in their fleet, which will be replaced and, with ESTFloattech’s batter y-hybrid system, the ship complies with IMO TIER III requirements Hagland’s new vessel programme is suppor ted by ENOVA SF (the Nor wegian Ministr y of Climate and Environment’s organisation aiming to reduce emissions and develop energy and climate technology) and the Green Shipping Programme for fleet renewal

The company claims that the new vessels will make the company ’ s fleet the most environmentally friendly in the sector www hagland com
