2. • 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)
6. Complex systems But also
knowledge of
Many criteria
the parts
Need for systems
approach for
decision making
7. ”Sustainability means meeting the needs of today without reducing
the quality of life for future generations”

8. sustainability?
According to Agenda 21
– Resource use and environmental impact
But also
– Social and economic dimensions
– The role of major groups

10. Ecoship main research groups
today
Chalmers – shipping and marine technology
• Applied hydrodynamics
• Maritime environment
• and in contact with other groups….
GU – school of business, economics and law
11. Related competences at
Chalmers and GU
At Shipping and marine technology

12. 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
13. 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
15. 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
16. Maritime environment
• Environmental impact from sea transport from a life cycle
perspective
– Energy supply chain – fuel selection, KA, SB
– Emission abatement, HW, MM, EF
– Energy efficiency , HL, KA
– Energy management, HJ, BS
• Environmental Risk Assessment
– Risks from “environmental time bombs” in the old ship wrecks,
IMH, FL
17. Relation technology ‐ nature
– Measurements and evaluation of emissions to air from
ship engines as a function of (abatement) technology
and operating modes.
• NOx , SO2, particles… EF, HW,
– Mapping of particulate emissions regionally, MA
– Studies of technical potential and environmental
impact from environmental technology
• biofouling abatement by ozone, SL
• sea water SO2 scrubbing, IMH
• Effect of NOx reduction technology, KA
18. Maritime environment
and school of business,
economics and law
• Impact of regulatory tools, scenario studies HW, KA, SL
• at School of business, economics and law, ZN, FL, ...
19. Reserach within maritime
environment internationally
• Many groups within marine science
• Few at technical universities
– Univ of Delaware – Corbett et al
– Gauss mbH – Univ of Bremen
– ...
• Consultants
– IVL
– DNV
– Lloyds
– ...
