GMIS-Propulsion was called to solve a problem with the feedback ring of a CPP system. The crew had reported several bolts to be broken off and a cracked ring. This caused the system to malfunction. The Service Specialist boarded the vessel in Hamilton, ON and solved the problem using OEM spare parts well in time before the vessel's ETD.

The owner saved time and money by not having to have a Service Engineer come from Europe.

The Service Specialist also provided consultancy regarding a leaking stern tube seal, saving the owner even more by not having the call an Service Engineer specialising in seals alone!
