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.
Sensorlink is working together with a UK North Sea operator to do a pilot trial this summer on a 12″ coated subsea pipeline. The test is set up to verify UltraMonit® performance when reading through 3-layer Polypropylene (3LPP) with an UItraMonit® retrofit clamp-on solution. The client is looking for a high resolution system to monitor their pipelines for different kind of corrosion and erosion. The pipeline that will be monitored for this test is expected to experience bottom-of-line corrosion.
As our monitoring tools, Sensorlink is now wireless – meaning that we only use cell phones. Direct dialing numbers to Sensorlink employees is no longer in operation. Use the front desk number +47 73 53 80 50 or call us on our cell phones. You will find our #s under the tab Contact Us.
Sensorlink is attending the NACE International Corrosion 2013 Conference & Expo in Orlando FL March 17-21 2013. Visit booth # 657 at the Expo for a talk about Non-Intrusive Corrosion/Erosion Monitoring.
Øystein Baltzersen and Ingar Nerbø will be presenting at the symposia Corrosion Monitoring in Subsea Installation in Orange County Convention Center 330 A on Monday 18th from 9 to 9:25. The subject is Corrosion monitoring of a polymer coated subsea pipe with ultrasound.
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.
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.
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.
Sensorlink acquired by Axess
Autumn 2010 the Axess Group acquired Sensorlink. The acquisition is based on Axess’ strategic intention to strengthen their position within integrity management and including advanced monitoring technology. Sensorlink’s product portfolio fits well with the primary markets of Axess; Total Rig Integrity Management, Inspection and Engineering Services.
For Sensorlink this acquisition represents an opening into the integrity management market. It enhances Sensorlink’s ability to provide more complete services in addition to their current product range.
Corrosion Monitoring Solutions Take Centre Stage
Sensorlink, a leading provider of corrosion management solutions to the oil and gas industry, announced that it has entered into an agent agreement with Kentron Systems Inc. in Calgary, Alberta, Canada. Kentron Systems will sell and distribute Sensorlink’s products for corrosion monitoring of pipelines and processing plants throughout Canada. Kentron is the first agent that Sensorlink has appointed to sell its products overseas.
“We are very happy to enter into this agreement with Kentron Systems in Canada. It is well established, and has a good reputation in Canada, which is a market that we feel offers a large potential for pipeline corrosion and erosion monitoring,” said Kenneth Jekteberg, Managing Director of Sensorlink. “Currently Sensorlink’s products are being used throughout the North Sea. This agency appointment is part of a strategic plan to achieve greater market penetration both onshore and subsea,” he added.
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 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.
