    • An instrument (17) for determining one or more stress characteristics within a surface layer of magnetisable material. Instrument (17) includes probe (7) having a carrier (8) rotatable about a rotation axis (Y) extending perpendicularly outwardly from a magnetisable material surface (M). An electromagnet (1) is mounted on t he carrier (8) and provides a pair of poles (3) spaced apart, one on either side of the rotation axis, on a pole axis (X) so that on carrier rotation the poles (3) circulate about the rotation axis (Y). The electromagnet (1) is energisable to produce a magnetic field (H) between the poles (3). A search coil (5) is fixed relative to the electromagnet (1) between the poles (3), on an axis (x) so as to lie in the magnetic field (H). Drive means (12) is operable to rotate the carrier (8) to selected angular positions. The probe (7) is positioned with the poles (3) adjacent the material surface (M) so that the magnetic field (H) extends into the surface, shifts in the magnetic field (H) caused by stress in the material surface (M) inducing representative voltages in the search coil (5) at the angular positions. Instrument (17) also includes control apparatus (18) for controlling operation of the drive means (12) and, at each selected angular position of the carrier (8) for receiving parameters from the probe (7) for determining the stress characteristics.

    • A method is described for measuring a change in the mechanical state aiming at detecting the disturbance the change in state has on a magnetic flux (o). This flux is brought to flow through at least a part of the body (1) under the influence of a driving magnetizing force (H0). In order to achieve an unambiguous measuring result the average length ((Alpha)) of the magnetic circuit is kept constant and independent of the change in the mechanical state. The flux (o) consists partly of a main flux (o0) having a definite direction and being of such a magnitude that the magnetic properties of the body depart from the region of irreversibility and partly of an alternating, gradually vanishing flux (oy) superimposed upon the main flux. The alternating flux must have such an initial magnitude that saturation is obtained in both directions of the alternating flux (ov). After the vanishing of the alternating flux (ov the disturbance generated through the change in the mechanical state is indicated or registered as a voltage which is induced by the change in flux corresponding to the disturbance. A device which works as explained above comprises means for generating the flux (o) through the body (1) which is arranged to form a magnetic circuit with at least a part of the body (1). This circuit should be essentially free from air gaps and have an average length ((Alpha)) for the driving magnetic force (H0) which is independent of the change in the mechanical state. The device is arranged to force partly the main flux (o0) and partly the superimposed alternating flux (ov) through the magnetic circuit. By means of a coil system (5) connected to a measuring or indicating device (8) the change in flux corresponding to the disturbance caused by the change in state is detected.

    • A flexible elongate generally cylindrical structure comprising at least one layer of steel ligaments near the outer longitudinally-extending surface, the steel ligaments extending at least partly along the length of the structure, such as a riser (10), may be inspected using an electromagnetic probe (40) incorporating an electromagnet core with pole faces (44) and an electromagnetic coil (46) to induce an alternating magnetic field, and at least two sensors (50) on each pole face (44) for sensing an alternating magnetic flux density. The inspection involves arranging the probe (40) adjacent to the outer longitudinally-extending surface of the structure (10), and inducing an alternating magnetic field less than saturation in the steel ligaments using the probe (40), and sensing the alternating magnetic flux density near the outer longitudinally extending surface of the structure (10). Measurements may be taken at a wide range of different frequencies. The probe (40) is scanned (62) over the surface, and the measurements are repeated at locations adjacent to different ligaments; from the flux density sensed by the sensing means (50) a parameter sensitive to stress in the ligaments can be determined, and from any variation of the said parameter between different ligaments any broken or over-stressed ligaments can be detected.
