This paper provides a comprehensive review of modern bathymetric survey techniques and their impact on offshore energy development. Bathymetric surveys are crucial for mapping the seafloor and supporting various offshore activities, including oil and gas exploration, renewable energy development, and submarine cable installation. The review highlights recent advancements in bathymetric surveying technologies, such as airborne lidar, satellite-derived bathymetry, and unmanned surface vehicles (USVs), which offer significant improvements in coverage, resolution, and efficiency compared to traditional methods like single-beam and multi-beam echo sounders. The paper discusses the historical evolution of bathymetric surveying, from early methods using weighted lines to modern techniques employing sophisticated instruments. Traditional methods have limitations in terms of coverage and resolution, necessitating the development of more advanced techniques. The impact of these advancements on offshore energy development is significant, enabling more accurate mapping of the seafloor, better site selection for infrastructure, and more effective environmental impact assessments. Modern bathymetric survey techniques have revolutionized offshore energy development by providing more accurate, efficient, and cost-effective methods for mapping the seafloor. These advancements are essential for meeting the growing demand for offshore energy resources while minimizing environmental impact and ensuring operational safety. The paper concludes by emphasizing the ongoing importance of continued research and development to improve the cost-effectiveness and scalability of advanced bathymetric survey techniques, as well as the integration of artificial intelligence and machine learning algorithms to automate data processing and analysis.This paper provides a comprehensive review of modern bathymetric survey techniques and their impact on offshore energy development.
