MJR Power & Automation improved an LPG Carrier's efficiency by retrofitting an active power factor correction system, reducing the need for continuous operation of all diesel generators. This enhancement realized significant operational benefits, including improved redundancy and cost savings, with the capital investment repaid within months.
MJR Power & Automation replaced three main diesel generators on a trading vessel, completing the re-engining program without vessel downtime. The challenging project involved meticulous planning, class-approved engineering, and successful integration, achieving cost-effective success.
MJR Power & Automation successfully replaced a defective PC-based valve control system on an LPG vessel, proposing a PLC-based solution utilizing existing cabling. The modular 'plug-in' retrofit was seamlessly completed during the vessel's service, achieving significant cost savings and ensuring reliable, redundant functionality without service calls since commissioning.
MJR Power & Automation successfully replaced the Portuguese Navy vessel's outdated Power Management System, ensuring optimal performance. The project involved custom installation, interfacing with the electrical propulsion system, and delivering key features for enhanced functionality.
MJR Power & Automation oversees the design, construction, and initial mobilization of two offshore construction vessels, offering expertise in ship specifications, electrical systems, DP performance, and integration of construction equipment.
In 2000, Maersk Responder became a Multipurpose Offshore Construction Vessel after a Cable Installation role. In 2008, MJR Power & Automation converted her back, overhauling, testing, and modifying systems within a tight schedule.
