The picture shows calculated and measured tip vortex from a propeller. By numerical estimation the propeller can be optimized together with the hull. Fuel consumption can then be minimized and noise and vibrations on-board can be substantially reduced.

The group Maritime Environment has grown from two persons, one associate professor and one doctorate student, in 2007, to 12 persons in summer 2009. Several of these are part time and shares their time with other groups outside and inside Chalmers, eg. the Swedish Environmental Institute, IVL, the Swedish Maritime Administration and the department of Energy and Environment at Chalmers. The research profile is connected to competences in hydraulics, maritime issues, and the interactions of shipping with the water and atmospheric environment. Environmental systems analysis using tools like Life Cycle Assessment (LCA) or Environmental Risk Assessment (ERA) is also important in the reserach. Studies of incentives for environmental investments within the shipping industry and energy management systems are also performed.The group is also accountable for an environmental database developed in collaboration with the Swedish Shipowners Association.
The group Computational Hydromechanics develops advanced numerical methods for estimating the hydrodynamic properties of ships, so far with the focus on propeller-hull-optimization, especially with regard to cavitation. Cavitation is today the limiting factor when it comes to propeller optimization. The methods are today too computationally heavy to be used in practical design work, but will be used by designers within the next 5-10 years. Of practical value today is the increased physical understanding extracted from the very detailed computational results.
The group Applied Hydrodynamics also works with methods for hydrodynamic optimization of ships and propellers. The focus here is on methods that can be directly applied by ship designers. The research has resulted in the software SHIP-FLOW, today used worldwide by shipbuilders, shipping companies, consultants and universities working in ship design. Together the two hydrodynamic groups are accountable for about 50% of the Naval Architect education at Chalmers University of Technology.
The group Engine Systems accounts for all of the education in Marine Engineering at Chalmers University of Technology and hols a high competence in the applications in the area. The group intends to also develop research within the engine area.
Researchers at the School of Business, Economics and Law at Gothenburg University, make contributions to Lighthouse foremost in the field of World trade and International Shipping, Logistics and Cargo handling, Financial Reports and Analyses and Maritime Law. Within Eco Ship the main applications are related to effect of policies, within legislation and in logistics.
Eco Ship
Eco Ship is led by Associate Professor Karin Andersson. This theme area is responsible for education and research related to the resource use and environmental impact caused by shipping and maritime activities.
