Le présent rapport évalue la disponibilité et la pertinence des données stir les vagues soulevées par le vent nécessaires dans l’industrie pétrolière et gazière pour les organismes de conception, les propriétaires ou exploitants, les sociétés de classification, les organismes investis d’un pouvoir de réglementation et les organismes de recherche pour la mise au point, la conception, la construction et l’exploitation des ouvrages qui doivent être utilisés pour les activités d’explorations et les forages de délimitations dans les eaux au large de la cote Est du Canada.
This report assesses the availability and adequacy of the wind generated wave data required by the oil and gas industry, including design organizations, owners or operators, classification societies, regulatory agencies and research organizations for the development, design, construction and operation of structures to be used in the activities of exploratory and delineation drilling in waters off the East Coast of Canada.

Des spectres de déplacement de surface, recueillis en cinq endroits au large de la cote ouest du Canada entre 1984 et 1989, ont été utilisés pour décrire le régime global des vagues, les types spectraux et les caractéristiques des tempêtes de cette région.
Surface displacement spectra, collected at five locations off Canada’s West Coast over a period extending from 1984 to 1989, were used to describe the overall wave climate, spectral types and storm characteristics of this region. Offshore waters experienced the most severe wave climate, as indicated by the joint occurrence of significant wave height (HSIG) and peak period (TP). Conditions of HSIG > 8m and TP > 17s were observed at all locations while the most severe record was represented by an HSIG > 13m and TP of 20s. Examination of the spectral types indicated a large percentage of swell dominant and multiple peak spectra which has implications towards both their numerical and parametric modelling. Fifteen storms, driven by both small and large scale pressure systems, were examined in detail and showed the presence of rapid sea growth (maximum rates on the order of 1 m/hr and 1s/hr for HSIG and TP) and, with the exception of Queen Charlotte Sound, an average 30% decrease in energy between offshore and inshore stations, intensification of sea conditions in Queen Charlotte Sound was observed on occasion (maximum intensification of 60%). The Ochi and Hubble six–parameter model was fit to all spectra. The statistical distribution of the fit parameters was calculated and an attempt was made to predict these parameters with varying success. The probability distribution of the fit parameters was also examined to define design spectra with known confidence limits.
