Siemens has added the SWT-8.0-154 unit to its offshore direct drive platform of wind turbines.
The German company said the addition of the 8MW turbine – first reported in subscriber-only newsletter reNEWS – will allow for up to 10% higher annual energy production under offshore wind conditions compared with the 7MW model.
It said the first SWT-8.0-154 will be installed in early 2017, with type certification expected to be obtained at the start of 2018.
The upgraded model includes new magnet technology with an even higher grade than that introduced in the SWT-7.0-154, Siemens said.
“This enables a rated power increase of more than 14% from 7.0 to 8.0 MW,” the company added.
The new unit has only had a few component upgrades, which means “customers will again benefit from fast time-to-market and low risk as the key value drivers”, Siemens said.
Meanwhile, Siemens’ SWT-3.3-130 machine has obtained type certification from DNV GL.
The company provided DNV GL with full access to the engineering design details, assembly facilities and the SWT-3.3-130 prototype installed at the test site in Høvsøre, Denmark.
Evaluation included assessment of the maturity of the turbine design, its manufacturing, installation and commissioning processes and the related documentation.
