Abstract

A method for use in inspecting a pipeline 14 comprises inserting a pipeline inspection apparatus 10 comprising a transducer array 32 into the pipeline and transmitting an acoustic signal 44 from transducers 34 towards an internal wall surface 22 of the pipeline at an angle of incidence obliquely aligned relative to said internal wall surface. A signal 48 reflected from the internal surface is received by the transducer arrangement and used to determine or estimate a condition of the wall. A further acoustic transducer array 36 may be included and reflected signals combined with the obliquely reflected signals. Properties such as wall thickness, roughness, corrosion, defects, cracks, deposition of hydrates and surface hardness may be determined. The apparatus is typically mounted on a pipeline pig.
