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.

Finland’s Oldest Ferry Goes All Electric
From steam to diesel and now electricity: the oldest operating ferry in Finland will tomorrow become the nation’s first all-electric passenger vessel after being fitted with Visedo power. The City of Turku will officially re-launch the historic Föri ferry tomorrow, complete with a new zero-emission electric drivetrain that will deliver greater efficiency, less noise and reduced operating costs. The Föri initially entered service in 1904, after the City of Turku commissioned local shipyards Aktiebolaget Vulcan to build a city commuter ferry to take passengers across the Aura River to Åbo.
Stena Line Says Sustainability Goals Paying Off
“Our belief is that a reduced environmental impact is also essential for long-term profitability,” said Stena Line's CEO, Niclas Mårtensson. Stena Line, a ferry operator serving Denmark, Germany, Ireland, Latvia, the Netherlands, Norway, Poland, Sweden and the U.K., said its increased strategic focus on sustainability and environmental improvements over recent years is paying off. Through the years Stena Line’s experience in investing in energy efficiency transport has been extensive. An example: the launch of the world's first methanol-powered ferry, Stena Germanica, in 2015.
Hybrid Propulsion for NCA’s New Vessel
The Norwegian Coastal Administration’s (NCA) new multipurpose vessel OV Ryvingen will be its second to combine traditional diesel power with battery-driven operation. The battery pack that Rolls-Royce has been commissioned to equip the Ryvingen with will have an available capacity of 2,000 kilowatt hours (kWh), an increase from the 850 kWh capacity that is installed aboard its hybrid sister ship the Bøkfjord. It is also has twice the capacity of Norway’s first fully electric car and passenger ferry, Ampere.
New Marine Battery System from Leclanché
The Leclanché MRS will be used on the E-ferry in Denmark, the world’s largest 100 percent electric ferry by battery capacity, equipped with a 4.3 MWh Leclanché Lithium-ion battery and scheduled for launch later this year. “There is a huge opportunity for marine vessels across the world to reduce their harmful emissions and cut their operating costs by leveraging battery storage technology,” said Anil Srivastava, CEO of Leclanché. “This is why we developed the MRS and we are delighted that it is the world’s first such solution to receive type approval from DNV-GL.

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.
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.
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.
Wärtsilä Supplies Propulsion for Fishing Vessel
