EffShip Efficient Shipping with Low
EmissionsBengt Ramne, ScandiNAOS AB
EffShip –Efficient Shipping with low emissions
• The EffShip project is a research and development project partly funded by Vinnova in their program for “Environment innovations”.
• The projected started in December 2009 and runs for 40 months until March 2013.
• The EffShip project is based on the vision of a sustainable and successful maritime transport industry – one which is energy efficient and has minimal environmental impacts
• One of the main objectives of the project is to identify the best and most effective way for the shipping industry to comply with the upcoming regulations regarding emissions

EffShip – WP2 Present and Future Maritime Fuels
• HFO
• LSHFO
• ULSHFO
• MDO
• MGO
• LNG
• Biofuel
• DME
• Methanol
• Synthetic
diesel
Where can we find alternatives to HFO?
Marine transport fuel consumption;
3 960
EffShip – WP2 Present and Future Maritime Fuels• LNG
– From natural gas– Complicated distribution and storage system
• Methanol– From natural gas, biomass, hydration of H2 and CO2
– Conventional distribution and storage systems– Similar fuel characteristics as LNG
• DME– From natural gas, biomass, hydration of H2 and CO2
– Similar storage and system distribution as LPG– Better diesel fuel characteristics than methanol
• Gas to liquid, GTL– From natural gas– Multiple fraction fuel– More expensive to produce than methanol
EffShip – WP3 Exhaust Gas Cleaning
• SOx– Acidification , acid rain
• NOx– Contribute to smog and increased
levels of ground-level ozone
• GHG– Contributes to global warming

EffShip – WP8Demonstration of Findings
EffShip
• Expected results– Identification and quantification of the best
alternatives to HFO operation– Detailed knowledge of cost and complexity for
the installation and retrofitting of the best alternatives for exhaust gas cleaning
– Detailed mapping of actual energy use and saving potential in short sea and deep sea shipping operation
– Detailed knowledge of cost and complexity for the installation and retrofitting of the and organic rankine cycle, ORC generator

EffShip• EffShip projektet har som sin uttalade målsättning att konkret
bidra till sjöfartens utveckling vad det gäller bästa möjliga energieffektivitet och minsta möjliga miljöpåverkan.
• Deltagarna i Effship: SSPA, ScandiNAOS, Wärtsilä, S-MAN, DEC, Chalmers Tekniska Högskola, StoraEnso, Göteborg Energi, Svenska Orient Linjen, Stena Rederi representerar de flesta sektorer inom sjöfarten.
• Bredden från design, akademi och underleverantörer via rederi till lastägare ger projektet en unik möjlighet att både ha helhetsperspektivet – bredden och detaljkompetensen – djupet, för att ta fram konkreta lösningar som för utvecklingen framåt.
