COPENHAGEN, April 11 (Reuters) - A 72-metre (236 ft) long blade fell off a wind turbine in Norway late on Wednesday, the Odal Vind wind farm said, adding that no one had been hurt in the incident.

The blade, weighing some 22 tonnes, fell off a Siemens Gamesa 5.0-145 turbine, part of the turbine maker's 4.X platform, a spokesperson for the wind farm told Reuters on Thursday.

Siemens Gamesa, owned by Siemens Energy, in 2023 warned of quality problems at its onshore unit with most of the issues linked to certain rotor blades and main bearings at its two most recent wind turbine platforms, the 4.X and 5.X.

"It is still too early to say anything on the cause of the incident," the Odal Vind spokesperson said, declining to comment on whether the incident was linked to the previously reported quality issues.

The entire wind farm was shut pending further investigation, it said in a statement.

Odal Vind last month said it had already stopped 15 of the wind farm's 34 turbines due to damage discovered on the blades, which it said was linked to a production error.

Siemens Gamesa did not immediately respond to a request for comment. (Reporting by Stine Jacobsen, editing by Terje Solsvik)
