analysis of all available information. If the software approach for asset integrity management is open and configurable for all existing and any new technologies, it then provides an excellent platform for solving complex issues in pipeline safety.

In recent years, highly effective technologies for pipeline surveillance against third party interference have become increasingly available. One typical example is fibre optic monitoring technology, which is designed for detecting various parameters, including temperature, mechanical deformation and acoustic emission within or near the pipeline. However, the market acceptance for new technology depends on economic considerations and for many existing pipelines fibre optics may not be the first choice for monitoring a pipeline environment. Tis fact has motivated the development of more conventional monitoring approaches. With advances in miniaturised sensor technology, pipeline monitoring can now be performed with a group of sensor-nodes, which are arranged to form a tightly correlated network. Wireless communication through RF and satellite systems makes a sensor network more flexible and cheaper to install. Satellite remote sensing technology with radar and infrared sensors provides another possible technological combination for proof of an event, including visual confirmation.
