Turkish shipowner Susesea, which has a fleet of six bulk carriers, has successfully upgraded its cylinder lubrication strategy by adopting Chevron’s Taro Ultra Advanced 40 (TUA 40). Working closely with Chevron Marine Lubricants and its regional distributor, Petrol Ofisi, Susesea has streamlined vessel operations and reduced cylinder oil feed rates by approximately 33%, resulting in both technical and commercial benefits.
The six Japanese- and Chinese-built vessels, each with an average deadweight of 64,000 tons, are all equipped with MAN Mark 9 engines. These two-stroke engines demand high detergency lubrication to help maintain piston and ring land cleanliness, particularly when operating on very low sulfur fuels. Previously, Susesea’s engineers alternated between MAN Category I and Category II lubricants to manage this requirement, following a set schedule of three days on Taro Ultra 40 (Cat I) and one day on Taro Ultra 100 (Cat II). The system was effective, but complex.
By transitioning to a single Category II 40BN product, Susesea not only simplified
