Europe's largest ecological catamaran, was developed by boat Builder Drassanes Dalmu electrically powered by solar panels, wind turbines, batteries, and diesel-electric thermal generators.
With a capacity of 150 seats, a length of 78 metres and a width of 34 metres, the eco-slim is aimed mainly at tourism and can cruise at eight knots.
The catamaran is 50% lighter and has 20 percent less drag than conventional models, thanks to the boat hydrodynamic design and innovative hull construction. The port and starboard were separate and joined together with a vacuum infusion system. As the eco-slim so easily and hydrodynamic, is to use its location less powerful engines.
A team of engineers from the Barcelona design school of industrial engineering and the Barcelona School of nautical studies at the UPC-Barcelona tech helped the catamaran.
Jordi Llorca from the Institute of energy technology (INTE), and Prof Ricard Bosch and Prof Victor backups of the Faculty of electrical engineering, developed the catamaran drive system with the help of the PhD student of Oriol Gallemis.
The system used two electric motors with multiple energy sources connected: run a diesel generator and a series of 90 batteries. The batteries are charged by connection to the generator or the two wind turbines and 40 solar panels on the deck of the boat either.
Involvement of all elements of the boats of energy supply system centrally controlled by an electronic management system. Along with navigational instruments is the electronic system of a lead battery and a 2 kilowatt hydrogen battery powered.
This drive system to the eco-slim continuously for four hours at six or seven knots sailing. Motor and batteries can be charged and a half again in an hour.
