Significant reduction of weight and space saving, leaving more cargo space.
VescoPlastics Celebrates 60
This year is the 60th anniversary of VescoPlastics and Vesconite, its first engineering plastic. The company's line of thermopolymers is used extensively in the marine, agriculture, heavy off-road equipment, pump, and hydroelectric and renewable energy industries.Founded by Alain Leger, an entrepreneurial engineer, Vesconite started in response to a need for an alternative to nylon bushings, which swelled and seized in humid underground mines. Years of testing resulted in a thermopolymer that had exceptionally low friction properties and could be machined to close tolerances.
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.

Hamburg Süd and Electrolux already carried out a fuel upgrade in the past, thereby making a contribution to environmental and health protection.
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.
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.
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.

The classification rules covering shaft alignment are formulated to achieve an acceptable distribution of loading on the shaft bearings and lubrication of the aft bearing…
Triple-screw Tug for the Hudson
“The Daisy Mae is the closest you can get to Z-drive maneuverability, without the cost of Z-drive,” maintains her builder Joseph Rodriguez of Rodriguez Ship Building Inc. in Bayou LaBatre, Ala. Rodriguez has designed and built a lot of tugs over the years and doesn’t make this claim lightly. Further more he backs it up with his description of the beamy 82 by 32-foot tug that his yard delivered to Coeymans Marine Towing. This is one of the Carver group companies based at the Port of Coeymans 110 miles up the Columbia River from New York.
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.
Rolls-Royce to Equip Baydelta’s New Hybrid Tug
Rolls-Royce said it will supply a hybrid propulsion arrangement for installation to a multipurpose tractor tug being built for Baydelta Maritime LLC at the Nichols Brothers Boat Builders shipyard in Washington State, U.S. The 100-foot long tug is due for delivery in the first quarter of 2019, and will feature the same ship assist and tanker escort capabilities of existing Delta Class harbor tugs but with improved towing performance.
