3.4 Ship lubricant types
When the question arises as to how to lubricate a ship correctly, the answer is that specific lubricants appropriate for the operating conditions and components on each ship need to be applied. The following are types of lubricants commonly used in different parts of ships.
Engines: These must meet the engine manufacturer’s specifications and provide adequate protection against wear, corrosion and excess heat.
Bearings: They have to provide adequate lubrication for bearings to minimise wear.
Transmissions: These oils should promote adequate lubrication for transmissions and reduce corrosion.
Lubricating greases: These are applied to lubricate components that cannot be greased with oil, such as shaft bearings.
Compressor lubricants: Oil must provide adequate protection for compressors, preventing excessive and premature wear.
