The post-storm inspection revealed a structural failure in one of the 12 pens, which had caused a tear in the netting.
“We are very disappointed that this structural failure has occurred,” says David MacGillivray, Mowi’s regional farm manager. “Despite storm Brendan severely battering many parts of Scotland’s coast last week and Colonsay being a remote and particularly exposed location, we expect our modern infrastructure to withstand these challenges.”
The farm’s net pens exceed both the Scottish and Norwegian technical standards for net pen design. The company and equipment supplier are immediately reviewing the net pen’s manufacturing process.
The incident is the third major escape from Mowi's new generation off offshore, high-energy sites in Scotland in the last 14 months. It follows on from two incidents at their Hellisay sites, in October 2019 and November 2018, in which 23,970 and 24,572 salmon respectively escaped.
