• What is Ecoship and sustainability? • Challenges for Ecoship• Research groups and projects• Maritime environment reserach in the world • Future research areas in Ecoship?• Current initiatives and reserach networks (Björn Södahl)

”Sustainability means meeting the needs of today without reducing the quality of life for future generations” http://www.un.org/esa/sustdev/index.html
sustainability?According to Agenda 21 – Resource use and environmental impact But also – Social and economic dimensions – The role of major groups

And to support the studies• Data base on ship emissions, energy/fuel use, operation etc• Close contact with problem owers – Identification of research issues – Make measurements under operation possible – Collect data – Case studies
Challenges in focus in Ecoship: • Resource use – Energy efficiency potential – Energy management – Energy sources – Energy efficient design• Environmental impact – Identify and quantify sources in technical system and effects of emission abatement technology • Related to emissions to air – CO2, NOx, SO2, particles, VOC… • Related to emissions to water – Ballast water, Sanitary water, Scrubbing, antifouling paint……• Organisational aspects – Policy, legislation, organisation and management tools – Logistics
Computational hydrodynamics Main objective: Energy efficiency and optimisation• New methods (SHIPFLOW) – Overlapping moving grids forseakeeping and manoeuvring – Basic LES theory• Applications – Influence of fouling on resistance – Far‐field wash waves – Propellers at extreme off‐design conditions – Cavitation physics – Basic cavitation prediction: foils – Cavitation prediction: propellers – Propeller‐induced noise and vibrations (fluid/structure interaction)• Automatic optimisation – Optimisation of aftbodies and flow control devices – Optimisation of hull‐propellerrudder interaction
