New Grease Extends Life, Lowers Temp of Tugboat Shaft Bearings

How does a tugboat operator with over 26 vessels used in docking, escort, ocean towing and articulated barge service get control of maintenance issues? In this case, by switching to Klüberplex BEM 41-132 grease to lower operating temperatures between 2 and 10 degrees Fahrenheit (3.6 and 18 Celsius), which significantly extends grease and bearing life. The tugboat business’ success depends on the reliability of their assets and the ability to provide superior customer service.

ABB Shaft Generators, Turbochargers for DFDS Vessels

ABB shaft generators will raise the energy efficiency on two DFDS vessels which have been designed to meet the latest environmental regulations. Two shaft generators will be installed in each of the cargo Ro-Ro ships allowing the main engines to operate at a wider, more optimal speed range. The shaft generator system takes its power from main engines, thereby increasing safety if there is a failure on the auxiliary engine. The ships’ main engines will also be turbocharged by ABB’s latest generation technology.
