Wind, wave and current data for the design of ships and offshore structures

Abstract

An important activity of the ISSC ever since its formation has been an ongoing review of ‘Environmental Conditions’. The mandate of Committee I.1 is presently: Concern for the description of the ocean environment, especially wave, current, wind and temperature statistics, in deep and shallow water, as a basis for the determination of environmental forces for structural design including some consideration on marine growth. Consideration also to be given to statistical descriptions of ice and earthquake phenomena relevant to design of ships and offshore structures. Of prime importance to the design of ships and offshore structures are the descriptions of ocean winds, waves and currents. Past reports of Committee I.1 have included important references and recommendations on these subjects. The chapters in this article have been edited from contributions to ISSC 1988 by the following authors: Wave and wind data sources (R. G. Quayle). Statistical analysis of random seas (M. K. Ochi). Ocean currents (S. P. Kjeldsen). Wave hindcasting and forecasting (J. A. Ewing). Directional wave spectra (Y. Takaishi).
