New stern tube fuel liquid meets US EPA rules

Nov 28 2014

Shell has launched a new range of Environmentally Acceptable Lubricants (EALs), including Shell Naturelle S4 Stern Tube Fluid 100.

The Shell Naturelle range of products enables ships entering US waters to comply with the revised 2013 Vessel General Permit (VGP). 

Shell Naturelle S4 Stern Tube Fluid 100 is made with fully saturated ester base oil, which offers the best resistance to hydrolysis (breakdown by water) and oxidation (oil ageing). It is also a non-emulsifying fluid, which allows ship operators to easily drain any water from the stern tube system, preventing hydrolysis and bio-degradation of the oil within the equipment.

Shell has received a wide range of approvals from stern tube OEMs, including Aegir-Marine, Blohm & Voss (SKF), Kemel and Wärtsilä Propulsion.

In addition, Shell has also launched its VGP-compliant range of gear oils, hydraulic oils, wire rope lubricant and greases, almost all of which has received EU Eco Label certification and a host of approvals from OEMs.
