Abstract: The gas industry has a very successful record of maintaining and operating a safe distribution and transmission system. However, accidental damage to underground gas distribution pipes by excavation equipment does occasionally occur and can be a costly and dangerous problem for the gas industry. Various methods are being used to try to prevent accidental, or third party, damage unfortunately these efforts have not been completely successful. In response to this, the Gas Research Institute is funding the development of several new concepts to help prevent accidental damage by excavation equipment. The projects being sponsored generally can be divided into two categories: (1) Pipe Avoidance Systems to help equipment operators avoid hitting underground gas lines during excavation and (2) Soft Excavation Tools, which have the ability to excavate a gas pipe without causing severe damage if it should come in contact with the pipe while digging. This paper briefly describes projects being sponsored by GRI in the area of Accidental Damage Prevention.
