Smart Pipeline to Debut in Norway

Oct 24, 2017

A team of engineers in Norway have previously announced the completion of a large collaborative effort to outfit offshore oil pipeline with thousands of sensors.  This new "smart pipeline" will be able to provide real-time data to operators both on ship and back at shore.  New technology like this will greatly assist in increased efficiency, the eliminating of downtime, and adherence to stronger safety standards.

As more "smart solutions" appear across numerous industries, data collection will become essential.  Canary is working hard to provide affordable industrial software that specializes in the storing of sensor data.  Read more about the smart pipeline below.

Greenlight For The World's First Intelligent Oil Pipelines

Electronics installed in Norwegian oil pipelines have been tested both at sea and in transport vessel reeling simulations. All that now remains is to install them offshore.  In recent years, researchers at SINTEF have been developing oil pipelines that can provide real-time condition monitoring reports by means of transmitting data to shore. This has been achieved in collaboration with industrial partners Bredero Shaw, Force Technology, Siemens Subsea and ebm-papst.

Last autumn, 200 meters of pipeline were laid in Orkanger harbor to find out if the electronics would survive being submerged and the sensors succeed in transmitting data onshore.  "The tests were successful", says SINTEF Project Manager Ole Øystein Knudsen.  Since then the researchers have carried out so-called "reeling tests" to investigate whether the electronics remain intact when the pipeline is reeled onto drums prior to transport offshore.  "Pipes are stretched and deformed during such tests, and because the electronics are vulnerable to bending, some of the sensors were destroyed", says Knudsen. "But now that we know what happened we can make some small modifications to better protect the electronics", he says.

Need for real-time information

The SmartPipe project has been active since 2006 when the Research Council of Norway and a number of oil companies joined forces to find the approx. 25 million needed to fund the research program.  As oil production moves into even deeper and more environmentally sensitive waters, the pipelines carrying the hot well stream to a production platform have to be in good condition.
Instead of basing condition monitoring on safety measures and inspections made every five years or so, the aim of this project has been to obtain continuous real-time information which will enable an entirely new approach checking pipeline status.

Belts packed with electronics

SmartPipe pipelines carry out condition monitoring in real time. This is achieved by installing belts around the pipelines packed with a multitude of sensors which measure pipe wall thickness, tension, temperature and vibration.  The sensor belts are located at 24-meter intervals along the length of the pipeline. A thick insulating layer of polypropylene covers the outside of the steel pipe construction, and this is where the electronics are concealed. It is also through this layer that wireless data transmissions can be sent either onshore or to the production platform.

US interest

After a year of tests, the project is now moving into its pilot phase.  Knudsen says that the project has been visited by an American oil company with whom he is having negotiations.  "The company contacted us following the Gulf of Mexico accident", he says. "Initially, they started their own project because they anticipated the future introduction of stricter pipeline monitoring regulations. But when they discovered that SmartPipe had come further down the road, they contacted us. We think this could be a commercial winner", says Knudsen.

From regulatory to real-time monitoring

The researchers see a number of benefits of the new pipelines. Since many pipelines also carry produced water from the reservoir, they are vulnerable to corrosion. This can be counteracted by adding small concentrations of inhibitor substances. However, errors in concentrations may occur and it may be some time before they are discovered. This may mean that a pipeline has to be decommissioned earlier than planned. Current pipeline condition monitoring by means of inspections and checks is also expensive.

The new system will make it possible to identify errors at an early stage and make adjustments.  Another important consideration is the monitoring of free-span sections of pipeline. In areas of undulating seabed, free-span sections may start to swing in response to marine currents.  "The new pipes mean that we can measure fatigue development and thus get accurate estimates of pipeline lifetimes", says Knudsen.
