AMOS Centre for Autonomous Marine Operations and Systems Annual Report 2014 Annual Report OUR VISION To establish a world-leading research centre for autonomous marine operations and systems: To nourish a lively scientific heart in which fundamental knowledge is created through multidisciplinary theoretical, numerical, and experimental research within the knowledge fields of hydrodynamics, structural mechanics, guidance, navigation, and control. Cutting-edge inter-disciplinary research will provide the necessary bridge to realise high levels of autonomy for ships and ocean structures, unmanned vehicles, and marine operations and to address the challenges associated with greener and safer maritime transport, monitoring and surveillance of the coast and oceans, offshore renewable energy, and oil and gas exploration and production in deep waters and Arctic waters.

AMOS has completed its second year of operation and has become a lively scientific centre of research on auton- omous marine operations and systems with the licence to create – competence, knowledge and innovations. The organisation efficiently operates with strong support from NTNU, as the host institution, and committed partner- ships with the Research Council of Norway, Statoil, DNV GL, MARINTEK, SINTEF Fisheries and Aquaculture and SINTEF ICT. In addition to the core activity of AMOS, several new associated research projects, which expand the capabilities of AMOS and the centre’s impact, are established with national and international collaborators.
