Modern bathymetric survey techniques have significantly enhanced the exploration and monitoring of offshore energy resources, playing a crucial role in offshore energy development. This review discusses the evolution of bathymetric surveying methods, from traditional techniques like single-beam and multi-beam echo sounders to modern technologies such as airborne lidar, satellite-derived bathymetry, and unmanned surface vehicles (USVs). These advancements have improved the accuracy, efficiency, and cost-effectiveness of seafloor mapping, enabling better site selection, infrastructure planning, and environmental monitoring for offshore energy projects. Traditional methods, while foundational, have limitations in terms of coverage, resolution, and accessibility. Modern techniques offer higher resolution, broader coverage, and greater efficiency, making them ideal for offshore energy exploration and development. Airborne lidar provides high-resolution data over large areas, satellite-derived bathymetry offers cost-effective and scalable solutions for mapping, and USVs enable autonomous data collection in challenging environments. The impact of these advancements on offshore energy development is profound. Improved bathymetric data allows for more precise identification of suitable locations for infrastructure such as oil and gas platforms, wind farms, and wave energy converters. These technologies also facilitate the monitoring of underwater structures and environmental changes, ensuring the safe and sustainable operation of offshore energy facilities. The historical development of bathymetric surveying has evolved from simple lead lines to sophisticated technologies, reflecting the growing need for accurate and detailed seafloor mapping. Modern techniques have revolutionized the ability to explore and monitor offshore energy resources, contributing to more efficient and sustainable development. As these technologies continue to evolve, they will play an increasingly important role in the responsible and environmentally sustainable development of offshore energy resources.Modern bathymetric survey techniques have significantly enhanced the exploration and monitoring of offshore energy resources, playing a crucial role in offshore energy development.
