Offshore unions have praised the down-valuing of Super Puma helicopters as a success for common sense.
Last week engineering giant Babcock said it had taken charges relating to down-valuing its fleet of 13 Super Pumas as part of a wider £120m restructuring of its oil and gas business.
It followed a series of fatal crashes involving the EC225 model, most recently a crash off Norway in 2016 which killed 13 people.
The model has not returned to operations in the North Sea.
