Abstract: An acoustic method and apparatus detects or characterizes a medium in a structure which may be a container, such as a pipeline for transportation of oil, gas, or hydrocarbon condensate. A pulse of broadband acoustic energy is emitted towards the structure by a first transducer. A return signal is generating by a second transducer from acoustic energy returned from the structure in response to the emission of acoustic energy. A return signal spectrum representing acoustic spectral components of the acoustic energy returned from the structure is derived from the return signal, and the medium is detected or characterized by applying a return signal processing medium detection or characterization algorithm to the return signal spectrum.

Abstract: An acoustic apparatus adapted to operate in a gas filled space from a first side of an object to be measured for making a non-contact thickness measurement thereof includes an electro acoustic transducer, a transceiver coupled with the electro acoustic transducer and adapted to excite electro acoustic transducer to output an acoustic signal towards the object to be measured and receive an acoustic response signal therefrom, and a signal processor adapted to process the response signal and determine a thickness of the object. The electroacoustic transducer has a transducer-to-gas acoustic interface, and the transceiver is adapted to operate the electroacoustic transducer so as to emit into a gas filled gap an acoustic broad band pulse towards the object and to receive an acoustic resonance response signal in the acoustic response signal at a level that allows acquisition of the resonance response signal above a predetermined signal to noise level.

Abstract: An apparatus and a method for determining a moisture ingress in an insulating layer surrounding a pipe, the insulating layer being surrounded by a tubular jacket. The apparatus includes an acoustic transducer in communication with an exciter adapted to provide a brief and broad banded acoustic signal which includes frequencies which by their propagation in the material of the jacket has a wavelength which corresponds to twice the thickness of the jacket or an odd multiple of twice the thickness of the jacket, and to process a reverberation signal emitted from the jacket in response to sending into the jacket the brief and broad banded output signal from the transducer. The signal processor is adapted to make a frequency analysis of the received reverberation signal for producing a frequency response curve, to establish features of the frequency response curve which are characteristic of a moisture content in the insulation material on the inside of the jacket, and to output an indication being specific for the moisture ingress.
