CeSOS - A World Leading Centre PDF Print E-mail

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.

Jørgen Hals successfully defended his PhD thesis entitled Modelling and Phase Control of Wave-Energy Converters.

I started my PhD project at CeSOS in January 2006 with focus on motion control of wave energy devices. Waves that travel on the ocean is energy that can best be absorbed if we continuously tune our converter such that it oscillates with the same rhythm as the waves. If ocean waves were regular, this would be a trivial task, but they are not.

Arvid Næss won the Freudenthal Medal PDF Print E-mail

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).
