A pipeline design method has been developed that can result in thinner walls for pipelines operating in certain conditions and thus reduce capital, construction, and operating costs. The method employs non-linear solutions, compared to the more conventional linear approach found in the world's major design codes. It is nonetheless believed to be acceptable to most of those codes, including the widely used US ASME B31.4 and B31.8. Pipelines transporting hot or temperate products in the Arctic and hot products in other regions can operate with thinner walls, according to this method. If the product is gas, the temperature to which gas must be chilled can be increased, thereby reducing gas-chilling loads and costs. When the pipeline design method described here is used in conjunction with commercially available software, the proposed engineering methods can be used to predict the internal forces and moments more accurately than those predicted by commercially available software alone.
