New Class Rules Favor Seawater Lubricated Props
Classification societies are changing their monitoring rules for seawater-lubricated propeller shafts in line with the rules governing the inspection and withdrawal of oil-lubricated stern tube systems. China Classification Society (CCS), for example, announced in July that if certain condition monitoring criteria are met, shaft withdrawal for inspection may be extended to 15 years. The rule change follows recent revisions by Lloyd’s Register and Bureau Veritas which published amended SCM and MON-SHAFT rules in January 2013 and January 2014, respectively.
Shear Stability: The Key to Proper EAL Gear Oil Selection
Selection of gear oil for marine thrusters or a stern tube lubricant for use with propeller shaft bearings is often based on analyzing price/performance characteristics of the lubricant and its availability. Now with the implementation of the 2013 Vessel General Permit, this analysis must be expanded to include environmentally acceptable lubricants (EALs) that meet the new EPA standards. To meet environmental requirements, EALs are blended from base oils other than mineral oil. They still meet the same lubricant objective – providing long-term equipment protection.
