Marine applications of 3D laser scanning include offshore installations & platforms and vessels/ships. Through 3D laser scanning, survey tasks required for retrofit, conversion, and maintenance of offshore installation & vessels/ships can be performed efficiently and accurately. Based on these surveys, designers can develop a model of a structure including its piping, machinery, and equipment. As no structure of a offshore installation or platform is the same, 3D laser scanning is an efficient solution to determine the feasibility and impact of installing or retrofitting machinery including piping and other systems. With 3D laser scanning, we are able to create accurate as-built 2D and 3D CAD models for any project no matter the size or complexity.
