Shaft Vibration Eliminated With Vesconite Hilube

After replacing the all-rubber cutlass bearing of his new Jeanneau Sun Fast 35 Tide The Knot two times in seven years, Robert Metzen sought an alternative. A fellow sailor told him about his positive experience with Hilube as a rudder bearing. Shortly after contacting Leandro Panzini from Vesconite distributor VesArg, Metzen had a state-of-the-art polymer bearing installed.At 2,300 rpm, a sailboat engine will spin its propeller shaft a million times in less than eight hours. Cutlass bearing materials such as rubber and bronze wear prematurely.

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.

Supporting Silent Ships

Have you ever had problems talking to someone in a noisy environment such as a busy restaurant? The same happens to marine animals, which use sound to sense and interact with their environment: for communication, navigation, finding prey and even for self-defence. High ambient noise levels, which include a contribution from shipping, have an adverse impact on marine life. The world’s oceans are becoming increasingly noisy. While the size of the global commercial fleet more than doubled since the 1960s, anthropogenic noise in the oceans has actually increased eightfold.

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.

A Case for Propeller Guards & Cutters

As I was preparing for Thanksgiving dinner I put on Indiana Jones and the Last Crusade. While Indiana Jones and Doctor Elsa Schneider were being chased by the Brotherhood of the Cruciform sword through Venice and their boat was neatly shredded by the propellers of a larger vessel, it had me thinking of how much propeller technology has changed over the years. And how hopefully Indiana’s boat did not actually damage that vessel’s propeller. Recently an article passed though my news feed about the first 3D printed propeller. This is indicative of the direction the industry is taking.

Inland Workboats Have Much to Gain from Diesel Electric Propulsion

Diesel electric technology, as part of a comprehensive engineering design process, should be considered by the inland towboat sector. Diesel electric propulsion is not a new concept. Like azimuthing drives, its application to the inland marine market has lagged behind other areas of the marine industry. Diesel electric has gained traction in industries where fuel economy and redundancy of propulsion systems for safety is paramount. In particular, vessels like passenger ferries and offshore supply vessels have enjoyed the benefits of the diesel electric systems.

Fishing Vessel Repowered after Big Hours

After 60,000 hours of service, crab fisherman Robert Ross decided that his 19-liter Cummins 1150M had earned a rest. The 500 HP engine had been a perfect match for his 72- by 26-foot aluminum boat so he ordered up a new Cummins KTA19-M3 at 500 HP, continuous duty, from his local supplier Cummins Sales and Service in Fredericton, New Brunswick, in eastern Canada. Ross had his well-maintained 39-year-old boat, the Kara-Matt, hauled out at a shipyard and Dugas Equipment Ltd. of Caraquet, New Brunswick took on the repower.

Lessons Learned from the El Faro Casualty

The U.S. Coast Guard has issued an alert informing operators of the role that the main propulsion lube oil system was found to have played in the 2015 sinking of U.S. cargo ship El Faro. All 33 crew on board died when the 790-foot El Faro sank close to the eye of Hurricane Joaquin near the Bahamas on October 1, 2015, while en route from Jacksonville, Fla. to Puerto Rico. Loss of propulsion during extremely heavy weather was revealed as a major contributing factor to the vessel’s sinking, according to The Coast Guard Marine Board Report on the incident.
