Shell Naturelle S4 - Premium Environmentally Acceptable Marine Lubricants
Shell Naturelle S4 represents the pinnacle of environmentally responsible marine lubrication technology, specifically engineered to meet the stringent requirements of modern environmental regulations while delivering superior performance. Shell Naturelle is a range of Shell Marine environmentally acceptable lubricants to help you meet the latest regulations for biodegradable lubricants.
Advanced Synthetic EAL Technology:
Shell Naturelle S4 variants are manufactured from fully saturated esters, designed to offer superior lubrication performance while also being readily biodegradable and having low ecotoxicity. This cutting-edge synthetic technology ensures excellent resistance to oxidation and hydrolysis while offering high-temperature thermal stability.
Three Specialized Variants:
Shell Naturelle S4 Stern Tube Fluid 100 - A non-emulsifying synthetic fluid specifically developed for use in stern tubes, engineered for the lubrication and corrosion protection of stern tube bearings with exceptional water separation and anti-foaming characteristics.
Shell Naturelle S4 Gear Fluid - An advanced synthetic fluid for use in gearing applications such as thrusters and propulsion drives, designed to offer superior load carrying performance while maintaining complete environmental compliance.
Shell Naturelle S2 Grease A600P 1.5 - A high performance fully biodegradable grease for use on open gears, wire ropes and cables. This product is formulated with renewable base fluids and contains a select blend of additives to offer corrosion resistance and high load carrying performance.
Key Environmental Benefits:
- EPA VGP Compliant - Environmentally Acceptable Lubricant (EAL) according to the definitions of the US EPA 2013 Vessel General Permit (VGP)
- Readily Biodegradable - Shell Naturelle Grease S2 A600P 1.5 is biodegraded by over 60% after 28 days in the OECD 301 F bio degradation test
- Low Ecotoxicity - Classified as 'not harmful' to bacteria, algae, freshwater and marine invertebrates, and fish when tested according to OECD and EPA test guidelines
- High Renewable Content - Made from >60% renewable raw materials. Shell Naturelle Grease S2 A600P 1.5 is also classed as minimally toxic and non-bio accumulative
- Reduced Environmental Impact - Offers reduced harm when used in marine environments compared to conventional mineral oils
- Non-Bioaccumulative - Prevents dangerous chemical buildup in marine ecosystems
Superior Performance Features:
- Extended Service Life - Fully saturated esters ensure excellent resistance to oxidation and hydrolysis while offering high temperature thermal stability
- Wide Temperature Range - Operation over the temperature range -20°C to 100°C with high viscosity index providing shear stable lubrication
- Excellent Water Separation - Excellent water separation properties allow excess water to be easily drained from lubrication systems
- Superior Adhesion - Excellent adhesion properties results in reduced lubricant consumption and reduced labour time for re-application
- Advanced Additive Technology - Advanced ashless (zinc-free) additives provide protection over a wide range of conditions
- Superior Load Carrying - Select solid lubricants and additives protect components from excessive wear, even under heavy loads
- Excellent Corrosion Protection - Specially formulated to provide optimal protection against corrosion, even under seawater influence
Marine Applications:
- Stern Tube Systems - Lubrication and corrosion protection of stern tube bearings
- Marine Propulsion Drives - Thrusters and controllable pitch propellers
- Wire Ropes and Cables - Open gears, wire ropes and cables with high resistance to water wash-off
- Gearboxes and Transmissions - Marine propulsion and auxiliary systems
- Industrial Marine Equipment - Bearings and components in circulated and splash lubricated systems
- Open Gear Systems - Low speed plain bearings (less than 500 rpm)
- Offshore Operations - Environmentally sensitive marine applications
- Port and Harbor Operations - Compliance with strict environmental regulations
Regulatory Compliance:
The VGP applies to any commercial vessel longer than 79 feet operating within three nautical miles of the U.S. coastline and mandates the use of environmentally acceptable lubricants in any application involving an oil-to-water interface. Shell Naturelle S4 ensures full compliance with these stringent environmental requirements.
