Snorre A, Photo: Rune Johansen, Statoil Upgrading systems on Snorre A The offshore industry is serious about maintenance. The ability to be able to plan ahead is crucial in order to ensure that maintenance and repairs don’t interfere with the production. “Offshore production facilities have a variety of rotating machines including compressors, generators and turbines. These systems play a vital role and must be maintained so that they remain in top condition so as to maintain an optimal production environment” says Tor Børge Salvesen, Senior Project Manager at Semco Maritime in Norway. Upgrades on Snorre A Currently the company is upgrading the vibration monitoring systems on Snorre A for Statoil. These systems provide crucial information about all vital rotating systems on the platform, thus making it much easier for technical staff to decide if and when maintenance is needed. Tor goes on to say “Sensors mounted on rotating machines monitor the vibrations. If changes are detected they might indicate that maintenance is needed. “If the changes in the vibrations are significant this may be an advanced warning of a serious defect which could develop into a fault” He explains that by using a monitoring system it is not necessary to make on-site inspections of the rotating systems, and it makes it much easier to plan maintenance. The Snorre A project includes 15 systems and has been ongoing since 2010, it will be concluded in December 2012. Engineering is provided by Semco Maritime in Esbjerg where 11 engineers are assigned to the project. Semco Maritime Norway has 12 employees assigned to the project in order to provide project management and 3 teams of 3 employees are working in rotation on the installation onboard Snorre A. 1
