Upon the return of P&O European Ferries' RoPax vessel 'Bison,' a comprehensive equipment refurbishment was initiated, focusing on the Soren T Lyngso UMS213 Machinery Monitoring & Alarm System and replacing the Exhaust Gas Temperature Monitoring System. MJR Power & Automation provided faultfinding, repairs, calibration, and installations.
MJR replaced the failed and irreparable NUNOTANI KEIKI PITCH LOGGER on P&O's European Diplomat with a telegraph order printer/pitch logger. The retrofit design ensures easy installation, flexibility, and compatibility with existing equipment, providing cost-effective solutions.
MJR Power & Automation replaced safety systems on P&O European Ferries' 'European Seafarer' after a Main Engine crankshaft failure. The project involved a wire-for-wire replacement with enhanced features and robust operation, leading to similar upgrades on two sister vessels.
MJR Power & Automation Controls secured a contract to retrofit Main Engine Bearing Monitoring & Protection Equipment for Andrew Weir Shipping's "River" class fleet. Services encompassed design, equipment supply, electrical and mechanical installation, and successful commissioning within the vessels' operational schedule.
The 17-year-old Torsion Meter on Tor Baltica had a failed and economically irreparable microcomputer, rendering the system unusable. MJR suggested a cost-effective solution, retaining serviceable components, resulting in a 60% overall cost saving for the owner.
MJR designed, built, and commissioned Allen Bradley PLC-based subsea cable burial plough handling control systems for The Engineering Business Ltd. Installed on three advanced Cable Laying and Repair vessels owned by Alda Marine.
