State Key Laboratory of Coastal and Offshore Engineering

Research direction 1

Metocean Conditions and Flow-structure Interactions

Researchobjectives of this direction are to (1) improve the current methodologies for predicting metocean conditions (winds, currents, surface waves and internal waves) that can be directly used in engineering designs, (2) explore fundamental physics behind complex flow-structure interaction problems, (3) develop predictive methods for dynamic responses of coastal and offshore structures under various environmental loadings and (4) tackle new technological challenges arising from and provide technical supports to the research activies in other four research directions.

2. Experiment on the performance of a floating wind turbine in metocean conditions



Research direction2

Estuary andCoast Managements

Theresearchobjectives in this direction are to (1) investigate the responses of coastal ecosystems and ocean environments to the fresh water, sediment and pollutant discharges from land and rivers and develop corresponding integrated predictive models for the responses, (2) develop management strategies and tools for eco-friendly estuary and coastal environments, (3) develop management plans and countermeasure technologies for coastline protections against increasing human activities and rising sea levels due to climate changes and (4) explore the impact of climate change on mechanical properties of ice in polar regions.

Research Direction4

Infrastructure Engineering for Marine Resource Extractions

The researchin this directionmainly focuses ondeveloping novel technologies for the design and safe operation of key infrastructure for energy and resource extractions from marine environments such as marine renewable energy, oil and gas, methane hydrates, aquaculture products and minerals from the seabed. The key infrastructures include fixed and floating platforms, renewable energy harvesting devices, subsea structures, pipelines and aquaculture facilities.
