MAXIMUM LIKELIHOOD MODELS OF JOINT ENVIRONMENTAL DATA FOR TLP DESIGN

The UK Department of Energy and the American Petroleum Institute (RP 2T) guidance for the design of TLPs differ in their approach. The former uses an extreme event philosophy in which return period wind, wave and current magnitudes are used; whereas RP 2T requires the environmental criteria be associated with the recurrence interval of the responses. This paper discusses how statistical data modelling and time-variant reliability methods can be used to calculate responses with a specific recurrence interval. To illustrate the process, a TLP model is used in a time-variant reliability analysis to compare the Department of Energy and American Petroleum Institute methodologies.
