Propeller makers innovate with methods and materials

Marine Propulsion: February 20 2019| READ ONLINE ...The design was verified by Applied Universal Engineering. Founding partner John Dannecker says that Sharrow Engineering took a “clean-sheet approach” to propeller design. “Using the latest generation of commercially available engineering software and state-of-the-art computing architecture, Sharrow Engineering has developed a proprietary design capability and process for their propellers,” he says. “This process pointed to a new propeller geometry that reduces fuel consumption and demonstrates superior vibration and noise characteristics.” Sharrow’s propeller provides a wider peak efficiency curve for greater utility over a wide scope of operational ranges and registers a 17% reduction in

Sulphur Cap 2020: Global Impact & Market Trends

SEA NEWS: Jan 4th 2019 | Global Impact & Market Trends  | READ ONLINE The global 0.50% sulphur cap will enter into force in 2020, and more than 70,000 ships will be affected by the regulation. Stricter limits on sulphur (SOx) emissions are already in place in Emission Control Areas (ECAs) in Europe and the Americas, and new control areas are being established in ports and coastal areas in China. As a result, ship owners are weighing their options to ensure compliance. What will the new global limit mean for ships? Under the new global cap, ships will have to use fuel oil
