Sensorlink awarded contract with West African operator

Early this year Sensorlink was awarded a contract by a major West African operator for delivery of one UltraMonit retrofit subsea unit. The contract is a collaboration between Sensorlink and our partner EON Engineering Ltd. The UltraMonit Retrofit will be installed on an existing subsea oil export pipeline to monitor corrosion rates and provide feedback on corrosion inhibitor effectiveness.

To minimise the installation cost and time, the UltraMonit is autonomous and battery driven with a wireless communication unit. Data from the UltraMonit unit uploads via acoustic communication to shore for use in the operation and asset integrity management.
The West African waters are challenging with respect to marine growth and deposits and we have therefore tailored the tool to ensure that the ultrasonic sensors work under as optimal conditions as possible, says managing director Harald Sleire. The contract is important, as it will demonstrate the ease of installing an autonomous retrofit tool to get valuable data about existing pipelines.

Sensorlink awarded major contract with BP

Sensorlink, in collaboration with Innovation Norway and NCEI partners, awarded a major subsea instrumentation contract.

BP have awarded Sensorlink a contract worth approximately 50 million NOK to deliver 10 of its UltraMonit® high precision corrosion monitoring systems for BP-operated Shah Deniz Stage 2 development project in Azerbaijan. The UltraMonit® instrument is to be used as part of Shah Deniz 2’s flowline Integrity Management Strategy, monitoring corrosion rates and providing real time feedback on the effectiveness of the injected anti-corrosions inhibitors.

Harald Sleire, Managing Director of Sensorlink, commented “This is a very important milestone not only for Sensorlink, but also as acceptance of the technology as a valuable tool in Oil and Gas production. The uniqueness of our none-intrusive technology is the level of sensitivity which allows detection of micrometre changes in corrosion rate within a matter of days. This capability is what distinguishes Sensorlink from many of our competitors and was a tributary factor in being invited to qualify for this esteemed contract”.

Mr Sleire also commented on the uniqueness of the Trondheim region which he felt was instrumental in the success of Sensorlink from qualification activities through to this delivery.

UltraMonit® corrosion monitoring unit installed on pipe system

The UltraMonit® technology was originally developed in collaboration with Statoil and Gassco and was then commercialised by Sensorlink.  The system was first qualified to work in conjunction with DEH (Direct Electric Heating), where Sensorlink collaborated directly with BP and SINTEF (one of the world’s leading authorities on DEH).

In initiation of the qualification, Mr Sleire emphasised the role Innovation Norway had had as an active funding partner in enabling the start-up of the project. During additional stages of the qualification Sensorlink have, and are still collaborating extremely closely with Inventas on subseas design, NCEI partner’s such as Simpro on manufacturing, vibration and temperature qualification (ISO 13626-8), and Norbit on pressure testing and quality assurance.

Sensorlink  have also worked closely with Axess Orkanger on weld qualification and with Bredero Shaw on thermal coating of the prototype. In the final stages of the qualification we have also had the pleasure of working with Statoil Rotvoll to perform what is known as TRL4 testing, where the complete UltraMonit® subsea unit was pressure tested in seawater over a 48 hour period to establish that the system is fully functional in its natural operational environment to water depths of up to 2000m.

Mr Sleire stated “This project marks a major breakthrough for Sensorlink in the subsea market with the 10 units being delivered to BP-operated Shah Deniz 2 Project over the next 2 years, thus securing a high level of activity and a unique opportunity to develop the company.

UltraMonit® Heidrun










Sensorlink installed a UltraMonit® subsea clamp on a water injection pipeline at the Heidrun platform in the North Sea 3-4 years back. The clamp was equipped with 96 ultrasound transducers for circumpherencial measurement around 50 cm along the pipe.









The system was designed with acoustic communication so that data could be picked up by the platform’s ROV. The data has not been collected the last year, and we were very curious about the data quality when it was picked up from the water in May 2013. The data was of high quality and with high resolution. The picture below showes a sample wall loss kurve for one measurement channel. This curve indicates that the wall lost 0,19 mm of wall thickness during the 315 days plotted. The average wall loss for the measurement area (all 96 transducers) over the same period was approximately 0,10 mm.









New PipeMonit® installation

Sensorlink is planning six new installations for a Canadian Oilsands operator this summer. The installation will then count 20 monitoring stations in total. The installations are wireless, with cell phone communication (GSM) and battery/solar power. The system provides the operator with exact real-time wall thickness measurment in 360 degrees around the circumference of the pipe (24 clock positions), wall loss rates, wear profiles and more. The operator is using this knowledge to optimize pipeline maintenance and replacement, as well as using the information when designing new systems. OPEX is reduced by moving away from manual inspection, and CAPEX is reduced by exstending pipeline lifetime.

Canadian energy company expand usage of PipeMonit®

One of Canada’s major oil producers instrument one of its pipelines with a complete PipeMonit® monitoring solution from Sensorlink. The solution enables the customer to monitor the erosion rates and optimise the service life of their pipelines.

After having tested the technology for more than a year in a limited area of the pipeline they decided on expanding usage of PipeMonit®. The testing included considering the impact of the Canadian harsh climate and operating conditions. Sensorlink are pleased to deliver and install additional fourteen fully autonomous measuring systems along the pipeline.

How it works

Each measuring points contains two sensor belts. The sensors are logging the erosion rate twice a day. The measurement data are sent via cell phone technology to the Sensorlink application server in Trondheim. Sensorlink provides a Managed Data Service to the customer which includes providing loss of wall thickness information via a secure web interface. The customer has easy access to the reliable and accurate data from anywhere in their operation.


Monitoring solution for flexible risers carcass dislocation

This condition monitoring application is one of the world’s first to be fitted inside a producing flexible riser. Sensorlink is capable of monitoring a dislocation of the carcass if it draws near the riser head.

An Ultrasonic (UT) reflector tag is fixed to the carcass. The UT sensor is placed on the outside of the riser end termination. The UT sensor detects the 3 mm reflector inside the 130 mm thick steel wall of the riser end termination. The monitoring results are displayed on a LCD screen in the instrument room.

Technology evolvement

Sensorlink developed this tailored version of the Pipemonit™  technology in close collaboration with Statoil, Mechanica and Oceaneering. The work resulted in an enhancement of the Pipemonit™ technology. The UT sensor relies on enhanced signal processing hence the capabilities of Pipemonit’s signal processing was improved considerably. In addition due to the hazardous environment the solution is delivered with the appropriate Ex classification.

Corrosion Monitoring Plays Vital Role in Verifying Pipeline Integrity

Industry-wide regulations stipulate that operators must comply with the increased demand for transportation of oil and gas in a safe and environmentally sound manner. As a result, pipeline operators are required to verify the integrity of their pipelines at all times. A corrosion monitoring system can play a vital role in a pipeline integrity management program by providing detailed and reliable information on pipeline status.

“Sensorlink’s products will blend nicely with the rest of our portfolio within instrumentation products for the oil and gas industry,” said Joe Schuler, President of Kentron. “This gives us the opportunity to better assist our clients in meeting their requirements for control of asset integrity and for cost- effective pipeline operations,” he added.


Sensorlink delivers measurement system for controlling vibration

Sensorlink was chosen as the supplier of the measurement system for monitoring vibration on the subsea installation of Statoil’s Gjøa field in the North Sea. The Gjøa field is due for start-up during 2010. The flexible riser (rough bore) used in connection with floating production platforms can cause vibration in the pipelines subsea and in the platforms’ piping system. Sensorlink delivered a complete measurement system to Gjøa for verification of the size of such vibrations.

July 2009 Sensorlink delivered the first part of the measurement system. Sensors were installed at several locations on the subsea structure of the Gjøa field and a cable was laid to the connection point. For the second half of the delivery, started in September 2009, the company delivered the data collection and communication solutions.

Among other things the measurement system is used to establish the relation between vibration and the production from the facility in question. This will ensure that the production equipment is not exposed to vibration levels beyond their tolerance specifications.
