Retrofit of the Main propulsion controls on “Mubarak Multicat”


The vessel was experiencing difficulties on their existing main CPP control systems. The Mubarak Multicat has twin screw electric driven main controllable pitch propulsion and the control systems were from Norris Germany. Our team inspected the vessel & studied the existing controls & came up with a solution which required only replacement of the controllers, I/O cards and the valve drivers. The rest of the wheel house control plates and the cabling remained the same. Given the existing location of the controllers in the engine room, more suitable high temperature i/o’s were used.

There were challenges during the installation as the systems were to be built on board the vessel and tested. With excellent team work and support from the vessel staff we completed the retrofit, FAT on board and sea trials were successful.
