Abstract
The present invention relates to a method and system of an arrangement of sensors that can be used to detect changes in burial conditions of a pipeline buried under a body of water. The method comprising: obtaining a first temperature of a fluid at a first location; obtaining a second temperature of the fluid at a second location upstream and proximal to the crossing of the body of water; obtaining a third temperature of the fluid at a third location downstream from the crossing of the body of water; generating an estimate of the temperature of the fluid at the third location by establishing the rate of change of temperature of the fluid using the obtained first and second temperature and the distance between the first and second sensors; and identifying pipe exposure when there is a deviation between the estimated temperature and the obtained third temperature.
