The BBC has tried out new safety equipment being brought in to save lives if another helicopter crashes in the North Sea.
There have been fears over the safety of offshore workers after a series of accidents in recent years.
The Civil Aviation Authority, which regulates safety, is bringing in a new life jacket that will give workers more time to escape underwater.
The new life jacket includes features such as compressed air and an improved noseclip.
Transport Correspondent Richard Westcott got to put the jacket through its paces in a water tank.
