Abstract Acoustic leak detectors (ALDs) are being used increasingly on offshore platforms as a means of detecting leaks of flammable gases. They detect a leak through the ultrasonic sound produced by the escaping gas jet during leaks of liquids under high pressure. These sensors have been shown to perform well under the conditions experienced on offshore platforms. HSE recognizes the benefits of using such devices possibly in conjunction with line-of-sight sensors to detect gaseous releases. The objectives of this study were to develop spectra of the sound produced from pressurized releases of liquids under a variety of realistic release scenarios, to analyse the responses of selected ALD sensors positioned at different locations relative to the point of release and to collect information for producing guidance on using ALD sensors for protection against leaks of liquids under pressure.
