Abstract
A device (10) for monitoring strain of an elongate member (12) is deployed underwater. The device (10) comprises a first clamp (14) configured to embrace and couple to the elongate member (12) at a first axial location, a second clamp (16) configured to embrace and couple to the elongate member at a second axial location separated from the first axial location, and a sensor which is responsive to an angle between the first clamp and the second clamp.

A device for monitoring strain of an elongate member deployed underwater, the device comprising a first clamp configured to embrace and couple to the elongate member at a first axial location, a second clamp configured to embrace and couple to the elongate member at a second axial location separated from the first axial location, and a sensor which is responsive to an angle between the first clamp and the second clamp.
A device for monitoring strain of an elongate member deployed underwater, the device comprising an angular sensor arrangement comprising (a) a first part comprising a magnet and (b) a second part comprising a magnetometer housed in a sealed pressure vessel, the first and second parts being connected in a manner that enables one to turn relative to the other, and the magnetometer being arranged to detect the magnetic field of the magnet, so that the magnetometer's output is representative of angle between the first and second parts.
