Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency
It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”. This article offers a few comments from the perspective of a propeller designer…

Tech File: Propelling Hybrid Electric Solutions
Growing interest in hybrid-electric power systems is expanding the search for new propulsion and energy-storage systems in the workboat sector, where compliance with emerging environmental regulations and a relentless pursuit of operational efficiency are driving change. To meet demands for cleaner more efficient power, owners are examining the potential for less conventional methods of energy generation and storage – such as fuel cells, lithium-ion batteries, super-capacitors, flywheels, wind and solar – to propel their vessels.
ABS Advises on Hybrid Electric Power Systems
ABS has published the ABS Advisory on Hybrid Electric Power Systems to help marine and offshore owners and operators make decisions about energy generation and storage. “ABS continues to lead industry safety with the first comprehensive Advisory to address the latest hybrid electric power technologies,” said ABS Chairman, President and CEO Christopher J. Wiernicki. With the increased industry focus on environmental compliance and operational performance, many owners and operators…
Rolls-Royce Celebrates 20th Anniversary of MTU Series 4000
Packed with technical innovations, the MTU Series 4000 engine received accolades when it was presented to international experts for the first time at the SMM trade fair in October 1996. Series 4000 engines were the first of their kind to be fitted with common rail injection as standard and were 10 years ahead of their time. The Series 4000 has gone on to become MTU’s biggest selling engine in production. To date, over 37,000 Series 4000 engines have been sold to customers across the world for a wide variety of applications from marine propulsion and energy generation to off-highway vehicles…

Wind Energy Generation Beats Gas Turbines
Ernst & Young conducted a study that presents an integrated analysis of the value creation potential of wind energy. The study was commissioned by Acciona and EDP Renováveis and compares two energy technologies, Combined Cycle Gas Turbines (CCGT) and wind, to analyze the impacts of microeconomic factors such as direct costs as well as macroeconomic factors including job creation, Gross Domestic Product contribution, energy security, grid integration costs, CO2 and the impact of wind power on electricity pool prices. Wind energy has a higher impact on tax revenues than other technologies.
