MAN B&W 70MC-C engine overhaul
Earlier this year, our Tuzla, Turkey team performed a major overhaul and repair project on a Suezmax tanker vessel fitted with a type MAN B&W S70MC-C main engine. We performed a complete overhaul of all cylinders, including liners, fuel pumps, and roller guides. All parts were transported to our local workshop, and various reconditioning works were performed within 18 days. This project is a perfect example of how having competent riding teams and local mechanical workshop capabilities can save owners time and money, as all issues can be dealt with locally without dealing with logistics or complicated procurement actions.
