A method of pinpointing pipeline chemical leaks from an aircraft is disclosed. The method works best when wind speeds are under 10 knots and for liquid chemical leaks when temperatures are above freezing. The method comprises flying the aircraft over the pipeline; continuously collecting an air sample from the exterior of the aircraft; feeding the collected air sample into an air analyzer which tests for high concentrations of the chemical potentially leaking from the pipeline; inputting the output signal from the analyzer to a computer; concurrently inputting a global positioning system receiver output to the computer; programming the computer to correlate the outputs from the air analyzer and the receiver; and checking the correlated output from the computer to locate high concentrations of the chemical and thereby identify pipeline chemical leaks. An apparatus for aircraft surveillance of pipelines is disclosed comprising: an air analyzer to measure concentrations of the potentially leaking chemical connected to an air sample probe outside the aircraft; a computer electrically connected to the output of the air analyzer; and, a GPS receiver electrically connected to the computer. In a preferred embodiment the apparatus further comprises a video camera mounted in the nose of the aircraft, and a VCR in the instrument platform inside the aircraft to monitor the pipeline and surrounding terrain beneath the aircraft to facilitate location of the leaks in the pipeline.
Une méthode pour localiser des fuites chimiques dans un pipeline depuis un avion est divulguée. La méthode fonctionne mieux lorsque les vents sont de moins de 10 nuds et, pour des fuites de produit chimique liquide, lorsque la température est au-dessus de zéro. La méthode consiste à survoler le pipeline par avion; à collecter en continu un échantillon d'air de l'extérieur de l'aéronef; à introduire l'échantillon d'air collecté dans un analyseur d'air qui teste la présence de fortes concentrations du produit chimique susceptible de s'échapper du pipeline; à introduire le signal de sortie de l'analyseur dans l'ordinateur; à introduire au même moment une sortie du récepteur du système de positionnement global dans l'ordinateur; à programmer l'ordinateur pour mettre en corrélation les sorties de l'analyseur d'air et du récepteur; et à vérifier la sortie corrélée de l'ordinateur pour localiser les fortes concentrations du produit chimique et ainsi identifier des fuites chimiques dans un pipeline. Un dispositif pour la surveillance aérienne des pipelines est divulgué, qui comprend : un analyseur d'air pour mesurer les concentrations du produit chimique susceptible de s'échapper connecté à une sonde pour échantillon d'air située à l'extérieur de l'avion; un ordinateur connecté électriquement à la sortie de l'analyseur d'air; et un récepteur GPS connecté électriquement à l'ordinateur. Dans un mode de réalisation préféré, le dispositif comprend en outre une caméra vidéo montée dans le nez de l'avion et un magnétoscope dans la plate-forme de l'instrument à l'intérieur de l'avion pour surveiller le pipeline et le terrain environnant situé sous l'avion afin de faciliter la localisation des fuites dans le pipeline.
