Abstract: Described is a fiber optic cable useful as a sensor for the detection of water or hydrocarbons. The fiber optic cable has sensor portions in line with fiber optic portions; the refractive index of the sensor portion changes when the sensor portion is placed in contact with water or hydrocarbons.

Abstract: A flexible polymeric pipe for transportation of oil, gas or water, having an unbonded reinforcing intermediate layer between two polymeric layers. The pipe has a vent for the intermediate layer which allows venting of gas from the intermediate layer through to the exterior environment. The vent is generally impervious to water but pervious to air and gas.

Abstract: A pipeline monitoring system, utilizing RFID sensors. The pipeline monitoring system includes a pipeline having at least one RFID sensor for a wireless remote detection of any one or more of pipeline conditions including hydrocarbons presence, moisture presence, temperature and strain, and an RF interrogator or transceiver capable of interrogating said sensor.

Abstract: An apparatus for heating an elongate tubular article, such as a heat shrinkable sleeve applied around a welded pipe joint during pipeline construction. The apparatus is in the form of a frame which can be disposed around the article, the frame having a heater device having both longitudinally disposed heating zones and radially disposed heating sectors, each of which can be independently controlled. Alternatively, or in combination, the apparatus can have an air circulation system. Also, a method for shrinking a heat shrinkable sleeve comprising use of said apparatus.

Abstract: The invention is directed to an apparatus for heating an elongate tubular article, comprising a frame member adapted to be disposed around said article, a heater with multiple heating zones and a controller for operating the heating device. The apparatus may be used to apply a heat shrinkable sleeve around a welded pipe joint. The heater may be infrared and also may use thin stamped sheets. If a heat shrinkable sleeve is used, the controller may activate the heating zones from the centre of the weld outward to eliminate pockets of air. The diameter of the interior of the frame may change along the length of the frame.
