7. Environmentally Acceptable Lubricants
Environmentally Acceptable Lubricants (EAL) are necessary for ships that operate in
USA waters, and this area could be extended.
These lubricants are necessary for all oil-to-sea interfaces, which include stern tubes,
thrusters, rudders, stabilizers, variable pitch propellers, underwater ropes and
machinery and underwater transmissions are made with base oils and additives which
are significantly different to those used for system and cylinder oil.
EAL must not be mixed into system or cylinder oils where they are to be used in
engine applications. Even small contamination of EAL (related to the base oil quality)
into system and cylinder oil can cause elastomer compatibility, water emulsification
and high temperature deposit formation issues.
