Bond Aviation Group said it was grounding "until further notice" its flights involving Eurocopter Super Puma helicopters for "safety reasons".
A Super Puma carrying 14 men came down 25 miles off the coast of Aberdeen shortly after midday yesterday. All arrived safely on land after air and sea rescues.
The 12 passengers and two crew were put in life rafts. Nine were flown to hospital, while the remaining five were taken to Aberdeen by lifeboat. One man was kept in hospital for observation.
The helicopter, operated by Bond Offshore, had been on its way from Aberdeen to the Maersk Resilient rig and the Ensco 102 rig when it encountered trouble.
Bond confirmed that the decision to make the "controlled descent" was taken by the pilot during the routine flight "in response to an oil pressure warning light".
Ashley Roy, director of commercial services, said: "The pilot and co-pilot should be commended for their skill in this procedure."
Jim McAuslan, general secretary of pilots' union Balpa, praised the crew, saying it "looks like a terrific piece of airmanship from very skilled pilots".
The Coastguard, RAF helicopters, and lifeboats were all involved in the rescue effort.
The ditching was the latest in a series of incidents involving helicopters in the North Sea.
A total of 16 people died when a Super Puma crashed when its gearbox failed while carrying rig men to Aberdeen on April 1, 2009.
And in February 2009, 18 people survived after a Bond Super Puma ditched in the sea 125 miles off Aberdeen.
Speaking last night, Mr Roy said: "It is the third incident in three years; however, thousands of hours are flown offshore in helicopters every year - safety is our priority."
