Performance and risk reduction are two criteria with continued importance in the marine industry, especially when it comes to selecting equipment lubricants. Performance is a must-have for a wide range of components to function properly, while on the environmental front, risk and liability, regulatory oversight and changing corporate mindsets are providing an opportunity for enhanced sustainability. Marine applications contain a variety of equipment and machinery that require lubricants, oils or greases. The list includes deck hydraulics (winches, cranes, ring line and pipe handling), stabilizers, bow thrusters, stern tube and continuous pitch prop, stern and elevator ramps, water-tight doors and even anchor equipment. Each of these equipment types tests the performance and sustainability of lubricants. Determining which fluids deliver that performance and sustainability was the mission for three companies in the marine drilling industry.
