Protecting North Sea crude oil production Seal type: John Crane Flexibox DRSP-1000 Eliminating unplanned outages on North Sea main oil line (MOL) pumps caused by poor John Crane seal performance, extending MTBF, stopping output losses and cutting maintenance costs Client challenge Main oil line (MOL) pumps and their mechanical seals are critical to offshore oil production. When one platform operator reported an epidemic of MOL pump seal failures, NASH helped to quickly pinpoint the causes, provide solutions and improve future seal performance associated with John Crane Flexibox DRSP-1000 units. Our response The NASH team reviewed the service history and assessed the condition of failed seal units. We also visited the platform to inspect both the pumps and seal support system at first hand.
