The objective of this thesis is to examine the efficiency, durability, and ecological consequences of lubricating methods employed in marine engines. The maritime industry has played a role, in promoting unity through international trade. Considering the role of trade in the world’s economies it is important to prioritize the upkeep of ships.

Numerous studies have extensively examined the lubrication system of engines as a factor influencing the shipping sector. Failing to prioritize lubrication practices, like inspections and maintenance has resulted in engine failures, within marine systems ultimately reducing their efficiency and causing breakdowns of ships.

This research investigates lubricants that could be used for ships, at sea and has also found the lubricant for marine engine systems. Sampling and analysis methods to ensure the accuracy of our results. It's important to develop protocols, for producing lubricants to protect marine ecosystems and enhance the performance of ships.
