A line (34) is deployed along a landing string (18) or along a marine riser (14) of a subsea well (24). The line has sensors (35), such as temperature sensors (35), distributed along its length. In one embodiment, the line comprises a fiber optic line that includes fiber optic temperature sensors distributed along its length. In another embodiment, the line comprises a fiber optic line used to transmit light, wherein the returned back-scatter light is analyzed to provide a temperature profile along the length of the fiber line. The fibre optic line can be deployed by connecting it to the landing string, pumping it down a pre-existing conduit (40) (such as a hydraulic or chemical injection conduit), or pumping it down a dedicated fib er optic specific conduit.
