摘要： An apparatus for generating electricity. The apparatus comprises a collar arranged to couple to a pipe and a support having a first planar face, the support being attached to the collar such that it projects away from the collar. The apparatus also has at least one thermoelectric generator attached to the first planar face of the support and a cover attached to the at least one thermoelectric generator.

摘要： A method of assessing fluid flow in a conduit, the fluid comprising hydrocarbons, the method comprising the steps of: (a) measuring optical variances resulting from at least one circumferential mode of vibration of the conduit by directing a monochromatic light source, such as from a vibrometer, onto an external surface of the conduit thereby providing a measured vibration of the conduit as a result of fluid flow in the conduit. The data normally accurately measures velocity of the conduit usually considered to be wideband noise. Accordingly, sample rates are high, such as at least 5,000 times per second. The data is then assessed, for example by using a Fourier Transform, and a pre-trained algorithm to predict fluid flow at that point in the conduit, or upstream or downstream thereof. An associated apparatus is also disclosed. Embodiments of the invention can thus provide a non-invasive method and apparatus for providing information on the nature of flow regimes in pipelines, such as subsea pipelines which can be useful to optimise production and reduce well testing and/or downtime.
