After-sales service & Engine Maintenance

Providing Information on After-Sales Service and Maintenance

We suggest and provide planned maintenance by using the maintenance records chart that’s been made into a database from the time that the ship went into service as well as constantly providing parts, so that our customers can use the UE engine safely and with peace of mind. In the unlikely event of a problem, we can take advantage of our strength as an engine developer, and respond promptly in cooperation with the development design department.
