Canadian study shows propeller edge deviations increase URN As any marine engineer or hydrodynamicist can tell you, propeller cavitation is a reality of shipping. But as the causes of anthropogenic underwater radiated noise (URN) fall under increasing scrutiny from environmentalists and regulators there is mounting pressure to develop a deeper understanding of this perennial problem. […]
Raising its game in the wide-bore, medium-speed engine stakes, MAN Energy Solutions has introduced its most powerful dual-fuel, four-stroke engine to date. Spanning the 7,800-18,200kW maximum output range, the 49/60DF design exceeds the larger 51/60DF in potency, while consuming less fuel, such that it is claimed to achieve a class-leading standard of efficiency in both […]

Building China’s first methanol-fuelled newbuilding is GSI’s latest step on it journey with new fuels.
Shiprepair & Maintenance: 2nd Quarter 2022
A number of technical innovations are underway which will aid the industry’s sustainability agenda.
The introduction of the 0.5% Global Sulphur Cap for marine fuels on 1 January 2020 represented one of the biggest changes to impact merchant shipping in modern times. Despite concerns – and IMO’s sulphur mandate coming five years earlier than originally expected – the switch went far more smoothly than many had predicted. Today around […]
The US green propulsion sector has taken off on an unprecedented scale in the past five years. Admittedly, it took a while to get into gear, though increasingly stringent emissions legislation (spearheaded by California) and exorbitant fuel costs have helped to push battery-powered solutions forward. Diane Seltzer, co-founder and CMO of Pennsylvania-based start-up Epoch […]
At first glance, ballast tanks might not seem the most obvious fit for RIBs and powerboats, typically being the preserve of larger, ocean-going vessels. However, switch the ballast tank’s key role from guaranteeing hydrostatic stability to preventing slamming at high speeds, and its utilisation aboard smaller craft makes a lot more sense. Excessive slamming […]
