Ship division【Running repair section】

Turbocharger gross weight amounts to 14,200 kg when it becomes the greatest turbocharger MET90 made by Mitsubishi Heavy Industries, Ltd. It is by no means easy to remove such huge turbo from the engine room of the ship. Our engineer goes into the engine room and carries out repair it when it is impossible to move the turbocharger.
Our running repair varies such as, “periodic overhauling,” “repair maintenance to solve the problem by foreign substance entering,” “troubleshooting the exhaust temperature rise.”
All of our running repairs are carried out by licensed engineers of the manufacturer.
