| Résumé | (Sommaire disponible en anglais seulement)
Offshore wind development offers an opportunity for a significant source of clean energy and has been explored by many countries around the world. In
Canada, while interest has been expressed in offshore wind, no projects have been deployed to date. The Canadian Energy Regulator Act, which came into force in 2019, enables the Canada Energy Regulator to review and authorize offshore renewable
energy activities, including wind, in Canada's offshore areas. Additional regulatory work and marine spatial planning activities underway support the realistic possibility of future offshore wind in Canadian waters.
The main focus of this report
was an assessment of existing offshore wind technologies and a preliminary discussion on their applicability in Atlantic Canada. The report also identifies knowledge gaps where further scientific investigation is required.
The report is divided
into five sections, each covering some of the major components of offshore wind technologies. Following the introduction, Sections 2 and 3 explore different turbine foundation types and construction methods, respectively. While fixed-bottom
foundations remain dominant, floating wind is increasingly gaining attention across several jurisdictions. Canada's Atlantic offshore has limited areas that are obviously well-suited for fixed-bottom foundations, but further work is required to
thoroughly characterize the geology with respect to offshore wind foundation suitability. Floating technologies could conceivably play a role in increasing the range of suitable areas.
Section 4 examines typical operating practices including the
deployment of an effective maintenance regime that accounts for accessibility challenges to ensure maximum project availability. Methods for optimizing production through effective meteorological forecasting, avenues for the management of excess
power, and meeting increasing load demands are discussed.
Section 5 describes known environmental impacts of offshore wind incurred over all three phases of the project lifecycle: construction, operation and decommissioning. Impacts from the
construction phase are generally viewed as being intense, but short-lived, whereas impacts from the operation phase can often be longer-lasting and more complex. Canada has defined many different types of ecologically significant areas and the
relevant legislation and administration of ecological protection laws and guidance is discussed, recognizing that further research will be required to characterize and mitigate ecological risk of offshore wind deployment in Canadian waters.
Finally, Section 6 presents an overview of specific conditions in Atlantic Canada relevant to offshore wind. Like many jurisdictions, Atlantic Canada's offshore region has a strong wind resource, with many locations that could be economically
viable from a wind resource perspective. The geological conditions are potentially more challenging, as regions with similar geological characteristics to those where offshore wind has been developed in other jurisdictions are limited. Overall, the
cold climate, coupled with complex geological and bathymetric conditions in Atlantic Canada result in a unique setting with various challenges for offshore wind, but learning from the industry developments in other jurisdictions, including recent
development on the US Atlantic coast, can provide meaningful insight into a future Canadian offshore wind industry. |

Bien que le Canada ait manifesté de l'intérêt pour le développement de parcs éoliens en mer, aucun projet n'a été réalisé à ce jour. Ce rapport
fournit des informations et des ressources dans le contexte du développement futur de l'éolien en mer au Canada. Les lacunes en matière de connaissances qui pourraient nécessiter une étude plus approfondie sont également identifiées. À un niveau
élevé, ce rapport passe en revue les méthodes de construction, les technologies de fondation existantes, les considérations opérationnelles, les impacts environnementaux potentiels, les mesures de protection de l'environnement au Canada et le cadre
physique canadien en mer. En général, les conditions météorologiques, la complexité de la géologie sous-marine et les considérations écologiques du Canada créent un environnement unique qui présente divers défis pour l'énergie éolienne en mer, mais
l'apprentissage des développements de l'industrie dans d'autres juridictions fournit un aperçu significatif des développements potentiels dans les eaux canadiennes. |
