Oil major Shell has taken 60 people off the Brent Bravo platform in the North Sea.
The firm said that “poor weather” was impacting delivery of diesel.
This resulted in a partial downmanning as a “precautionary measure”, the operator said.
A spokesperson for Shell UK said: “Shell UK can confirm that 60 personnel from the Brent Bravo platform have returned to shore as a precautionary measure.
“Poor weather has impacted the delivery of diesel and we are working to reinstate supplies as soon as possible, weather permitting.”
Brent Bravo is 115 miles (185km) north east of Lerwick in Shetland.
