abstract

The objective of this study is to develop a methodology for use in geothermal pipeline route selection. Special emphasis is placed on finding the shortest route and minimizing the visual affects of the pipeline. Two different approaches are taken to solving the problem. In the first method a distance transform algorithm is used both for visual effects ranking and to obtain the optimal path. Subsequently a genetic algorithm is used to modify the route with regards to necessary expansion units. Included in the tool is site selection for separators and pipeline gathering points based on visual effects, incline, inaccessible areas and total distance to boreholes. The second method uses the Non-dominated sorting genetic algorithm II (NSGA II) to obtain the optimal path with regards visual effects, route length and pipeline gradient. This method uses the distance transform ranking method along with constraints on route length to generate the initial population for the genetic algorithm. The methods are implemented for the Hverahlið geothermal area.
