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.
