ABSTRACT: Geotechnical investigations for wind farms in remote areas present unique challenges requiring careful planning and execution. Increased demand for wind energy has led to the development of projects in remote locations, where access, seasonal conditions, and communication limitations must be addressed. Key logistical considerations include securing permits, engaging with First Nations and local communities, and preparing for extreme weather conditions such as heavy snow, wildfires, and wildlife hazards. Sparse investigation points in these areas make it difficult to develop comprehensive geological and geotechnical models, requiring engineers to adopt conservative approaches. Effective safety measures, including emergency preparedness and equipment maintenance, are crucial for successful field operations. This paper presents lessons learned from past projects and offers recommendations for improving geotechnical investigations, such as utilizing advanced remote sensing and geophysical techniques. By addressing these challenges proactively, wind farm developers can enhance project efficiency, safety, and sustainability in remote environments.
RÉSUMÉ: Les études géotechniques pour les parcs éoliens situés dans des zones isolées présentent des défis uniques nécessitant une planification et une exécution méticuleuses. La demande croissante en énergie éolienne a conduit au développement de projets dans des régions éloignées, où l’accès, les conditions saisonnières et les contraintes de communication doivent être anticipés. Parmi les considérations logistiques essentielles figurent l’obtention de permis, la consultation des Premières Nations et les communautés locales, et la préparation aux conditions météorologiques extrêmes, notamment les fortes tempêtes de neige, les feux de forêt et les risques liés à la faune. Le faible nombre de forages dispersés complique l’élaboration de modèles géologiques et géotechniques précis, nécessitant des approches prudentes. L’adoption de mesures de sécurité efficaces, telles que la préparation aux urgences et l’entretien des équipements, est cruciale. Ce document propose des recommandations visant à améliorer l’efficacité des études géotechniques et à favoriser la réussite des projets de parcs éoliens dans des régions isolées.
