For safe production with no leakage on the offshore oil platform, the leakage test must be done after the hydrostatic test according to the correlative standard of the high pressure or flammable fluid system. The He-N2 test can measure the leaking amount accurately with helium leakage detector. This method has potential applications in the leakage detection of high pressure oil and gas pipelines.

Key words: marine oil and gas pipeline, leakage detection, He-N2 mixed gas, quantitative detection
