Claim 14:
15. A method of preparing a multi-phase submarine power cable for operation, the method comprising:
a) providing a multi-phase submarine power cable including a plurality of power cores arranged in a stranded configuration, the multi-phase submarine power cable having an open end,
b) providing a curvature sensor including an elastic elongated member and a plurality of Fibre Bragg Grating, FBG, fibres extending axially along the elongated member at a radial distance from a centre of the elongated member, and
c) pushing the curvature sensor from the open end of the multi-phase submarine power cable in between the stranded power cores and along a central axis of the multi-phase submarine power cable;
wherein the elongated member is in direct contact with one or more of the power cores in a plurality of axial locations along an axial length of the elongated member as the elongated member extends inside an interslice or cavity between the power cores.
