It is understood all 14 passenger, including two crew on board made it into a life raft after the chopper ditched in the water 30 miles east of Aberdeen shortly after midday today.
The EC225 Super Puma helicopter operated by Bond Offshore, was heading from the Scottish city to the Maersk Resilient and Ensco 102 drilling rigs – in the Jasmine field.
Rig operator Conoco Phillips said the passngers were on their way to support the drilling rigs.
The chopper made a ‘controlled descent’ after a low pressure warning light came on during its flight.
A spokesman for the Bond said: “A low pressure oil warning light came on and the helicopter made a controlled descent and landed in the North Sea. It didn’t crash.
“The 14 passengers and two crew are safe and are in the life raft.”
Aberdeen Coastguard responded to the alert. It is understood passengers of the stricken helicopter are uninjured.
Jim McAuslan, general secretary of British Airline Pilots Association, considered the ditching as a “terrific piece of airmanship from very skilled pilots”.
Helicopter flights out of Aberdeen have been suspended for the time being.
First Minister Alex Salmond said: “Thankfully it has been confirmed that all on board have been rescued.
“Incidents such as these remain very rare but do serve as a stark reminder of the dangers faced by those offshore workers who are required to use helicopters on a regular basis.
“Once all of those involved have been transferred ashore the priority will be for the appropriate authorities to investigate the causes of this accident and ensure the future safety of flying operations in the North Sea.”
