Elevated pipelines in cold regions will lose heat to the environment and raise the ground temperature below the pipe. The maximum temperature in the ground is the (steady) solution of Laplace’s equation with boundary condtions appropriate for summer months which are complicated by the insulating effects of mossy vegetation that grows in cold regions. A linear decomposition of the problem was accomplished to permit isolation of the thermal effects for the pipeline. That is, increases in ground and vegetation temperature due to the presence of the pipeline were obtained so that the environmental impact of a pipeline can be assessed.
