New EAL Grease for ATB Couplings

Maritime Activity Reports, Inc.

April 27, 2018

Specialty lubricants manufacturer Klϋber Lubrication recently introduced a new environmentally acceptable lubricant (EAL) grease for articulated tug and barge (ATB) couplings, Klüberbio AM 12-501.

Klüberbio AM 12-501 is an adhesive EAL grease designed specifically for the large plain bearings, rams and connectors used in ATB coupling systems. It is based on fully synthetic ester oils for high performance and biodegradability, aluminum complex thickener for adhesion and resistance to water and select additives to reduce wear.

Klüberbio AM 12-501 meets ATB coupling system OEM specifications for pumpability, resistance to water washout and spray off, corrosion protection and load carrying capabilities. According to the manufacturer, operators may be able to reduce their current lubricant consumption based on the improved performance of the fully synthetic base oil, thickener and additive package.

Klüberbio AM 12-501 complies with the 2013 Vessel General Permit requirements of the U.S. Environmental Protection Agency (EPA) for biodegradability, minimal toxicity and bioaccumulation and therefore qualifies as an EAL.
