More than 71% of the earth surface is covered by water. There is limitless energy covered or held by water, such as oil and gas under the sea floor, ocean thermal energy, tidal energy, wave energy, offshore wind energy, as well as solar energy. However, to harness these energies is far beyond simple and straightforward, due to challenges of the complicated geology and harsh environment. The Offshore Energy Systems programme (OES) aims to explore, research and develop innovative and breakthrough engineering methodology/methods and technology/techniques for harnessing different types of offshore energy in a reliable, sustainable, cost-effective and environmentally friendly manner. The OES programme especially focuses on the modeling, optimization, control and fault/failure diagnosis of offshore oil and gas production processes, offshore wind turbine/wind farm, marine communication and underwater robotics.
