MME Group recently completed the replacement of an outdated Shaft Grounding System on the clients’s cruise ship. In addition, we installed our latest innovation: The Digital Monitoring Box. This smart solution provides advanced real-time performance monitoring of critical ship components and ensures long-term protection of critical propulsion components.
Rotating propeller shafts can generate harmful electrical currents, caused by ICCP systems and sacrificial anodes. These currents lead to premature wear or severe damage to bearings and drive systems. If these stray currents are not properly managed, they can cause corrosion in the propeller shaft, bearings, and gearboxes.
Our Shaft Grounding System prevents this by safely discharging the electrical load, significantly extending the lifespan of your drive and propulsion system and reduces the risk of costly repairs.
MME’s shaft grounding systems can be used in combination with both Sacrificial Anodes (SA) and Impressed Current Cathodic Protection Systems (ICCP-systems). This way, your vessel receives double protection against harmful currents and corrosion.
In addition to the mechanical protection provided by our Shaft Grounding System, MME Group has developed the Digital Monitoring Box, an advanced system for real-time measurement and analysis of critical vessel components.
This system continuously monitors the grounding of propeller and thruster shafts, recording electrical load and wear while detecting environmental conditions that can lead to corrosion.
This proactive approach will extend the lifespan of your assets, improve safety, and reduce costly downtime and unexpected maintenance.
The project required close cooperation with the Superintendent and Chief Officer on board. MME Group was responsible for coordinating and executing the project, including steel works, during a port call in Rotterdam.
Removing the old system posed challenges such as corrosion and limited space. Corrosion and constrained space made removal of the old system difficult, but precise planning ensured a seamless installation.
After disassembly of the old Shaft Grounding System and cleaning the propeller shaft, the new system was installed, followed by the Digital Monitoring Box for real-time monitoring.
It was crucial to complete the work on time to avoid any delays in the vessel’s sailing schedule.
Thanks to the teamwork of MME with the crew onboard and flexibility of our colleagues Age Leiseboer (System Engineer) and James de Rochemont (Corrosion Consultant), the project was completed within one day.
The SETO’s response highlights the success of the project:
“Good afternoon MME Group, we are quite impressed on how your team managed to complete the installation of the new shaft earthing yesterday in the port of Rotterdam.”
By partnering with MME Group, the client now benefits from a reliable, efficient Shaft Grounding System that provides optimal protection against harmful currents and extends the vessel’s operational lifespan.
