New ship handling tug & CNG powered tug
This demo case provides two demonstrators. The first demonstrator is the RSD (Reverse Stern Drive) 2513. This tug is of an entirely new type with improved hydrodynamic characteristics and TwinFin technology. The second demonstrator is the ASD (Azimuth Stern Drive) 3212 CNG-E, which operates with compressed natural gas (CNG) as a fuel and has an additional hybrid (E) propulsion as well.
The potential of methanol as alternative fuel
A major challenge that is faced by the shipping industry is the reduction of harmful emissions like soot, nitrogen oxides (NOx) and sulphur oxides (SOx). A possible solution is the introduction of methanol in the marine fuel pool.
SECA Refit Strategy
As per January 1, 2015, sulphur emissions by ships in Sulphur Emission Control Areas (SECA) has been limited substantially, requiring vessels to either switch over to a more expensive low Sulphur fuel or install abatement technologies in order to clean the exhaust gases before they are emitted into the open.
Expanding the application of ESDs to ships with CPP
In FP7 project GRIP, MARIN and Wärtsilä with partners worked on designing and optimising Energy Saving Devices (ESDs) for ships fitted with a Fixed Pitch Propeller (FPP). This resulted in the full scale demonstration of nearly 7% reduction in required propulsion power on a bulk carrier.
Large Diameter Propeller for General Cargo Vessel
Shipping produced 0.8 billion tonnes of CO2 in 2012, or 2.2% of worldwide carbon emissions, and there is sustained pressure on the industry to reduce both its carbon footprint and its fuel consumption. In addition the burning marine diesel fuel releases SOx (sulphur oxides) and NOx (nitrogen oxides), as well as associated particles (PM) into the air which can have a wide variety of negative health and environmental impacts.
Decision Support System for ship energy efficiency
The Demo Case activities will focus on an holistic approach to energy efficiency and emission reduction on board passenger ships of different sizes. The entire ship energy balance, the ship lay-out, the integration of innovative technologies into various configurations and the improvement of hull appendices and propeller hydrodynamic characteristics will be studied for new buildings and retrofit ships.
Energy efficient systems for leisure/passenger ship
The Demo Case activities will contribute to enhance the energy efficiency of leisure / passenger ships with a consequent reduction of emission into the atmosphere in terms of emission / payload (number of passengers) / mile ratio, in full compliance with the applicable regulatory framework at competitive conditions.
