More than 90% of global freight is transported by over 33,000 merchant marine vessels powered by two stroke crosshead engines as their main source of propulsion; the two-stroke diesel engine has been the backbone of global trade and globalization for well over half a century. Among one of the key factors supporting the reliability and uptime of these engines, keeping trade moving, is the effective performance of cylinder oil. Often referred to as the lifeblood of the engine, these oils provide critical protection to avoid abrasive…

The maritime sector’s longstanding reliance on Specific Fuel Oil Consumption (SFOC) and manufacturer power curves to measure fuel efficiency masks real performance as well as real inefficiencies at sea, according to Rob Mortimer, CEO of Fuelre4m:These legacy metrics, rooted in idealized factory conditions and theoretical assumptions, fail to capture the complexities of actual vessel operation. This results in an industry managing appearances rather than actual fuel-to-thrust efficiency…

Is Port of Amsterdam in sight? Then it's time to turn the diesel engine off and the electric motor on. That's the agreement that has been made with Sendo Shipping.By 2020, two of their Sendo Liners will be entering the port of Amsterdam emission-free. Port of Amsterdam has a stake in these new ships in the form of a loan.The Sendo Liners are inventive hybrid container ships. Much lower emissions, much lower fuel consumption and more cargo space. No less than 8% extra loading capacity! That's exactly one extra container length.With the Sendo Liners, Port of Amsterdam aims to make an active contribution to a more environmentally friendly future for shipping.

Washington State Ferries will begin the process of converting three Jumbo Mark II vessels from diesel to hybrid-electric power.The government agency that operates automobile and passenger ferry service in the U.S. state of Washington as part of the Washington State Department of Transportation (WSDOT) announced Tuesday the state will receive $35 million from the federal Volkswagen settlement to retrofit the Tacoma, Wenatchee and Puyallup.The ferry system is the largest consumer of diesel fuel in the state with over 18 million gallons of diesel burned each year, and the three Jumbo Mark II ferries account for 26 percent of total fuel consumption. This step brings the state ferry system closer to meeting the goals outlined in Gov.

Germany's Kaufbeurer Mikrosysteme Wiedemann (KMW) has introduced a higher performance version of its Z01 sensor for measuring cylinder pressure in large diesel, gas and dual-fuel engines.“The further developments center on the measuring capability, accuracy and robustness of our Z01 sensors,” KMW project manager Daniel Maaß explains.“To facilitate the measurement of higher combustion pressures and to contribute to overall robustness, we have increased the temperature resistance of the sensing elements we use in the Z01 sensors. At the same time, new connection technology aims to improve overall resistance to both temperature and vibration.
