Summary on Grant Application Form |

This proposal seeks to extend what is currently the most comprehensive offshore environmental data collection programme at a platform on the UKGS involving continuous collection of wave height and direction, wind speed and direction, current and wave particle kinematics. Data has been collected with this system since 1994 and the proposal is to extend this until 1999 thus providing an extensive set of storm data collected at 5Hz which will allow examination of the joint behaviour of wave, wind and current. The project will study the statistical relationships between these variables in the 3-hour interval (for which statistics have traditionally been collected); developing suitable joint probability models with measures of parameter uncertainty. The work of the existing project looking at max-stable models, peaks over threshold approaches and other joint probability models will be extended. These models will then be examined in the light of existing models based on 3-hourly average data. The NESS hindcast model for example, provides the joint probability of significant wave height average windspeed and residual current for 3-hour intervals for the last 25 years. A combination of these data and the models developed in the project should provide reliable joint probability models for use in design.
