...Philip Jonathan; Kevin Ewans Statistics of storm peaks over threshold depend typically on a number of covariates including location, season, and storm direction. Here, a nonhomogeneous Poisson model is adopted to characterize storm peak events with respect to season for two Gulf of Mexico locations...

...Philip Jonathan; Kevin Ewans The characteristics of extreme waves in hurricane dominated regions vary systematically with a number of covariates, including location and storm direction. Reliable estimation of design criteria requires incorporation of covariate effects within extreme value models...

...Kevin Ewans; Philip Jonathan The characteristics of hindcast data for extreme storms at a Northern North Sea location are shown to depend on storm direction, reflecting storm strength and fetch variability. Storm peak H S over threshold is modeled using a generalized Pareto distribution...

...Paolo Boccotti The quasideterminism (QD) theory introduces a deterministic wave function (of both space and time) that shows what, most probably, will happen if an exceptionally large wave will occur at some point in a sea storm. This deterministic wave function holds for every configuration...

...Nuno Fonseca; Ricardo Pascoal; C. Guedes Soares The structural loads on a floating production, storage, and offloading platform induced by a large set of realistic (measured) abnormal waves are compared with the loads induced by “design storms” and also with the minimum values required...

... such as the Gulf of Mexico and off the North West Shelf of Australia, extreme sea states are associated with hurricanes, but these occur relatively infrequently (by comparison to extra-tropical storms in the North Sea, for example). Moreover, hurricanes are relatively small scale by comparison to extra-tropical...

... phase, to improve the modelling of the higher significant wave height. The ability of the MNN to reconstruct sea storms is tested by applying the equivalent triangular storm model. Finally an application to the NOAA buoys moored off California shows a good performance of the MNN algorithm, both during...

...B. F. Ronalds; N. R. Anthony; S. Tuty; E. Fakas The structural reliability of a generic caisson under storm overload is investigated using typical Australian North West Shelf (NWS) environmental data. The bending moment due to the hydrodynamic loading is shown to increase in proportion...

...Rodney Pinna; Beverley F. Ronalds; Mark A. Andrich Assessments of structural reliability under storm overload have been performed on various monopod configurations located on Australia’s North West Shelf (NWS). The results have shown that these monopods have lower reliabilities than typical...

... a database of applications to date. The relationship between jack-up configuration and structural reliability under storm overload is then explored. Critical values of the wave height exponent α are presented for a wide range of water depths and jack-up geometries, along with selected pushover analysis...

...R. G. Bea; R. Iversen; T. Xu The extreme condition storm wave crest heights for many older platforms indicate that there would be “green water” in the lower decks. The API guidelines to determine wave forces acting on the decks of these platforms indicate that most platforms cannot survive...
