Abstract
Wind and waves present the main causes of environmental loading on seagoing ships and offshore structures. Thus, its detailed understanding can improve the design and maintenance of these structures. Wind and wave statistical models are developed based on the WorldWaves database for the Adriatic Sea: for the entire Adriatic Sea as a whole, divided into three regions and for 39 uniformly spaced locations across the offshore Adriatic. Model parameters are fitted and presented for each case, following the conditional modelling approach, i.e., the marginal distribution of significant wave height and conditional distribution of peak period and wind speed. Extreme significant wave heights were evaluated for 20-, 50- and 100-year return periods. The presented data provide a consistent and comprehensive description of metocean (wind and wave) climate in the Adriatic Sea that can serve as input for almost all kind of analyses of ships and offshore structures.
Highlights
The WorldWaves database was used in this study to derive wind and wave statistics for the Adriatic Sea, which is a semi-enclosed sea basin with specific wind–wave climate
Modelling applied forlocation, modellinga the joint distribution of significant wave height and peak period. This method bility distribution model was derived with the(spectral) aim to optimize parameters that will defines theto probability density function (PDF)for byreturn a marginal distribution and the a set of later be used determine extreme sea states periods longer than database conditional probability densities, each of which is modelled by a parametric function span and to provide a consistent approach for determination of loads for fatigue and whose analyses parameters optimized by mathematical fitting techniques to represent data from strength ofare ships and offshore structures
The conditional distribution of the wind speed as a function of the significant wave height can be described by the two-parameter Weibull distribution as proposed by BitnerGregersen and Haver [24] and included in Det Norske Veritas (DNV) return periods (RP) C-205 [2]:
Summary
The database represents numerical wave model hindcasts with assimilated available satellite altimetry measurements [19,20] It includes 39 locations, evenly distributed across the Adriatic Sea with 0.5◦ × 0.5◦ (lat.-long.) spacing, in the period from September 1992 to January 2016. A total of 39 locations were available within the WW database for the Adriatic Sea. The locations were analyzed: individually, grouped into regions (southern, central and northern Adriatic, according to DHMZ–Croatian Meteorological and Hydrological Service official subdivision) and joint together for the basin as a whole.
