Dozens of workers have been removed from the TotalEnergies (PAR:TTE) Culzean platform in the UK North Sea after a loss of power.
The operator said 46 non-essential personnel were down-manned following the incident, which took place around 8pm Saturday.
A total of 70 people remain on board the installation, 142 miles east of Aberdeen.
The incident took place during a planned platform shutdown.
TotalEnergies said there are no concerns for the safety of the platform or those remaining on board.
A spokesperson said: “The incident occurred around 2000hrs Saturday, April 22 while the platform was undergoing a planned production shutdown, and there are no concerns for the safety of the asset or those remaining on-board.
“The company is in the process of reinstating power to the Culzean installations. As part of those efforts, two specialists, along with equipment, have been flown to the platform as work to resolve the situation continues.”
TotalEnergies started production from the asset in June 2019, which is responsible for around 5% of UK gas demand.
Discovered in 2008, it was the largest gas project to be started up in the UK for 25 years.
BP (32%) and NEO Energy (18.01%) are partners on the asset.
TotalEnergies is one of the largest operators in the UK sector.
Recently it has been hit by a string of HSE issues, including warnings from the regulator over delayed maintenance backlog on some older assets.
Eslewhere, in February, the firm’s Elgin platform was at the centre of an incident when a helicopter had the blades ripped off of it – while workers were still on the helideck – during Storm Otto.
Last month the operator spoke openly about the incident, including reasons for sharing footage, in a bid to share lessons on safety in the sector.
