SCHOTTEL's Mechanical Hybrid Propulsion Solution
In a close collaboration with Svitzer of Denmark, SCHOTTEL has developed a new hybrid propulsion concept. The new concept is based on the recent SCHOTTEL Y-Hybrid thruster technology and connects a port and starboard mounted azimuth thruster in a vessel with each other. This makes it possible to drive two thrusters with either one of the main engines. The companies are now discussing a pilot project to retrofit an existing tug with the new mechanical hybrid technology. This will transform the direct driven vessel into a greener and more cost-efficient vessel.
Rolls-Royce Wins Propulsion Contract for Nine RoRo Vessels
Rolls-Royce Commercial Marine has won a significant contract to deliver the propulsion system to nine vessels to be built by Nanjing Jinling Shipyard Co in China for the Italian Grimaldi Group.The nine 238 meter long vessels are so called Ro-Ro vessels (Roll-on-Roll-off) designed to transport over 7,800 linear meters of rolling units, equivalent to about 500 trailers. They are named the Grimaldi Green 5th Generation, and will be hybrid powered by combining use of traditional fossil fuels during operation and battery power when in port. The vessels are being designed by Knud E.

Hydrogen on the High Seas
George Skinner, a safety expert with Ballard Power Systems, based in Vancouver, Canada, discusses why hydrogen makes sense as a marine fuel.As a global provider of innovative clean energy solutions, Ballard Power Systems has years of experience in the deployment of hydrogen fuel cell systems for land-based use, with the first developments dating back to 1983. Ballard’s work with marine hydrogen as a fuel goes back to their role as advisors to the Canadian military.“The Canadian Navy has had fuel cells in their submarines since 1993,” George Skinner says.
World First: Navigator Aurora Converted to Run on Ethane Fuel
The recent conversion of a slow-speed marine diesel engine to operate on Ethane as a fuel marks a world first.Navigator Gas, in partnership with Charterer Borealis, engine manufacturer MAN Energy Solutions, cargo system and fuel gas supply system supplier TGE and ABS, has completed the successful conversion of the Navigator Aurora’s main engine from LNG fueling to Ethane fueling, while berthed alongside at Frederikshavn in Denmark.“This is the latest example of how ABS is collaborating…
The Modern Approach to NOx Reduction
ADNOX A/S, the R&D start-up in which Hans Jensen Lubricators A/S recently acquired the majority stake, has released details of their Advanced Diesel NOx reduction method, “ADNOX”. The ADNOX System is a SCR system using diesel oil as reductant offering more than 80% NOx reduction. The oil injected is converted to heat, leaving 50% more heat for recovery. No need for storage tanks for the reductant. No extra overall costs of reductant. The waste heat can be recovered for production or electricity. Significant reduction of weight and space saving, leaving more cargo space.

Wärtsilä Supplies Propulsion for Fishing Vessel
Lunar Fishing Company Ltd, based in Scotland, is replacing its existing Lunar Bow purse seiner trawler with a new ship having the same name. The primary considerations were to achieve both economic and environmental benefits through selecting the market’s most efficient propulsion machinery. The vessel is being built at the Karstensens Skibsvaerft shipyard in Denmark and will feature a fully integrated propulsion solution from Wärtsilä. The main engine chosen is the Wärtsilä 31, listed by Guinness World Records as being the world’s most efficient four-stroke diesel engine.
Supporting Silent Ships
Have you ever had problems talking to someone in a noisy environment such as a busy restaurant? The same happens to marine animals, which use sound to sense and interact with their environment: for communication, navigation, finding prey and even for self-defence. High ambient noise levels, which include a contribution from shipping, have an adverse impact on marine life. The world’s oceans are becoming increasingly noisy. While the size of the global commercial fleet more than doubled since the 1960s, anthropogenic noise in the oceans has actually increased eightfold.
Interferry Mission: Strength from Unity
Interferry CEO Mike Corrigan explains the Stronger Together vision behind the trade association’s drive to extend its networking and lobbying influence. Over the past four decades, Interferry’s reach and purpose has evolved with increasing effect from its U.S. origins in 1976. Back then, it was formed as the International Marine Transit Association with a focus on networking among its members. Now it is highly respected and influential as the only body representing the ferry industry worldwide.
Moving Ahead Powerfully
The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.
