Maritime Engineering Nordic Master in Maritime Engineering Participants: Nordic Five Tech alliance (Chalmers, DTU, KTH, NTNU, VTT) Development of programme supported by Nordic Council of Ministers with 1 000 000 DKr. Shipping and offshore are important to all Nordic countries. Nordic world-leading maritime companies (e.g. Stena, Rolls-Royce, A.P. Møller-Mærsk, Det Norske Veritas, Wärtsila) require the best candidates. Large future technical challenges. The Nordic Five Tech universities are strong in the field. Cornerstones of the programme (2 years, 120 ECTS, BSc entrance): - international and Nordic recruiting, - exchange between universities (one to two semesters at a partner university), - advanced summer courses (Nordic Master students and others), - complementary specialities at the partners, e.g.: CFD, yacht design, ship operations, decision support, emissions, high-speed craft, composites, offshore, fishery and agriculture, ice navigation, cruise liner design, (Chalmers) (DTU) (KTH) (NTNU) (TKK) 6 DTU Mechanical Engineering, Technical University of Denmark

Strategisk satsning - I: Teknisk forskningscenter til nedbringelse af emissioner ved skibstransport Formål: At demonstrere, hvorledes en betydelig reduktion af skibsfartens energiforbrug og tilhørende emissionsudslip kan opnås ved at kombinere nye, avancerede analysemetoder for skibes fremdrivningsmodstand med teknologiske nyudviklinger inden for fremdrivningsudstyr. Ansøgning sendt til Det Strategiske Forskningsråd i dag 9 DTU Mechanical Engineering, Technical University of Denmark
Strategisk satsning - I: Teknisk forskningscenter til nedbringelse af emissioner ved skibstransport Tre hovedområder: Reduktion af skibes modstand (i bølger) ved optimering af skrogformer, som tager hensyn til de lavere forventede fremtidige sejlhastigheder Optimering af fremdrivningssystemet, herunder effektiv udnyttelse af spildvarme samt reduktion af skadelige emissioner Beslutningsstøttesystemer, som skal hjælpe kaptajn og rederi med at optimere rutevalg og fart under hensyntagen til såvel økonomi, energiregnskab, forventet vejrlig, belastninger på skib og last samt maksimal ønsket sejltid. 10 DTU Mechanical Engineering, Technical University of Denmark
