Abstract
For use in the monitoring of a tubular member (1) having at least a helically wound reinforcement layer (10), the invention provides a method of mounting a sensor arrangement (17, 18), wherein the reinforcement layer is formed with a groove (16) which is filled with a liquid material (19), such as an epoxy type, and wherein the sensor arrangement is passed into the liquid material by means of a pressure applied by a roller prior to the solidification of the liquid material. In a preferred embodiment, the groove is formed in the reinforcement layer before this is helically wound on the tubular member.
Hereby, the sensor arrangement is arranged well-protected without any risk of damage, which may e.g. occur if the tubular member is of the unbonded type, where the reinforcement layer may consist of two layers that may move relative to each other. Furthermore, the sensor arrangement is protected against the external mechanical impacts that may occur if the groove is provided in a reinforcement layer which is freely exposed to the surroundings. The invention is particular suitable for tubular members, including umbilicals that are used for the recovery, refining and transport of oil and gasses.
