Regulations and Environmentally Acceptable Lubricants (EALs): Marine Applications that Use EALs
EALs should replace traditional petroleum lubricants in all marine applications where there is any oil-to-water interface. Marine vessels contain a variety of equipment that require lubricants, oils or greases. The oil-to-water interfacing equipment includes stern tubes, stabilizers, thrusters, rudders, propellers, bow thrusters, etc.
While legislation has not yet mandated the use of EAL in deck equipment, it is recommended by the EPA in the 2013 VGP to use biodegradable lubricants.Applicable deck equipment includes deck cranes, winches, mooring drums, windlasses, capstans, emergency towing arrangements, hatch covers, etc.
