P&O Ferries install MPM Hibernation system upgrade. UK ferry operator P&O Ferries has recently taken delivery of Marine Software's MPM Hibernation upgrade for vessels "European Seaway" and "Pride of Dover" after deciding to put these vessels into lay-by. The MPM - Marine Planned Maintenance product was originally installed during a fleet wide software purchase in 2005 for 18 vessels, along with Marine Software's centralised Spare Parts, Procurement package and CODA finance system integration.
