CeSOS - A World Leading Centre |
 |
 |
 |
Research at the Centre for Ships and Ocean Structures (CeSOS) aims at developing fundamental knowledge about how ships and other structures behave in the ocean environment, using analytical, numerical and experimental studies. This knowledge is vital, both now and in the future, for the design of safe, cost effective and environmentally friendly structures as well as in the planning and execution of marine operations.  The importance of such work cannot be over-emphasised: in tonnage terms 95 percent of all international transport is by sea; and 20 percent of the world’s oil and gas is produced from subsea reservoirs via offshore structures and pipelines. In the future, food production in aquacultural plants and exploitation of renewable energy from the oceans is expected to play a growing role.
The scientific and engineering research carried out in the Centre takes account of such future needs, and extends current knowledge in relevant disciplines. The emphasis is on hydrodynamics, structural mechanics and automatic control, and in the synergy between them. In each of the past years, our research projects have proved valuable basis for the innovative design of structures, risers and automatic control systems. Our focus is the development of fundamental knowledge concerning the design and operation of future ships and ocean structures. We accomplish this by integrating theoretical and experimental research in marine hydrodynamics, structural mechanics and automatic control. |

Nine new PhD's at CeSOS in 2011 |
|
|
|
|
In 2011, nine PhD candidates obtained their doctoral degrees at CeSOS. Among them were Biao Su and Jie Wu, both candidates within the field of structural mechanics, who gave their disputations on the same day.
CeSOS aims at being a "doctoral school", with the goal of improving research quality, methodology and process. In 2011, nine excellent candidates obtained their doctoral degrees. Dr Biao Su gave a trial lecture entitled “Moored Offshore Structures in the Arctic- Ice Management and Design Philosophy” and defended his thesis entitled “Numerical Predictions of Global and Local Ice Loads on Ships”. Dr Jie Wu’s trial lecture was entitled “Design Considerations Related to Vortex-Induced-Motion (VIM) of Deep Draught Waters”, and his doctoral thesis that he publicly defended was entitled “Hydrodynamic Force Identification from Stochastic Vortex Induced Vibration Experiments with Slender Beams”. Both candidates were applauded for their scientific achievements and for their presentations.

The Fridtjof Nansen award for outstanding research in science and medicine in 2011 goes to professor Odd Magnus Faltinsen for his work in marine hydrodynamics.
Rewards can be awarded to Norwegian researchers, or researchers resident in Norway, which has provided scientific contributions of international significance on very high level.
The prize of NOK 150 000, a medal and diploma was awarded to him by the Nansen Fund at the Norwegian Academy of Science and Letters' annual meeting on May 3rd.

We congratulate Professor Arvid Næss (CeSOS and Department of Mathematical Sciences, NTNU) with the Alfred M. Freudenthal Medal he was recently awarded at EMI2010 (Aug 8-11). Arvid Næss is the first Norwegian who has won this award. The highly prestigious medal is awarded biennially (every two years) by The American Society of Civil Engineers (ASCE). |

Automatic control workshop in arctic surroundings |
|
|
|
|
Professor Thor Inge Fossen is the co-editor of Parametric Resonance in Dynamical Systems together with Professor Henk Nijmeijer (Eindhoven University of Technology). The book is a compilation of articles on parametric roll and active roll damping, involving 23 contributors. In June they met in Svalbard for a workshop to further discuss the phenomenon of parametric resonance and present the book chapters of the new book that will be available in December 2011. A highlight of the workshop was when Professor Henk Nijmeijer who has contributed significantly to this field of science was knighted as the 6th Honorary Knight of the Order of the Golden Feedback Loop. Everyone who receives a doctoral degree from the Department of Engineering Cybernetic are elected to Knights of the Order of the Golden Feedback Loop (the order has about 200 knights). 
Professor Nijmeijer kneels down for Professor Fossen to swear the solemn oath of Cybernetics: I, Knight of the Golden Feedback Loop promise to promote the control science in all my conduct by always behaving optimally and never entering the right half plane. Must all controllers help me in this my solemn vow. |
