Operations. In an emergency and at oversea commands Air Force personnel may be required to take over operate and maintain a cross-country pipeline system. The command fuels engineer will provide technical oversight to the BCE responsible for all maintenance of pipelines acquired by the Air Force. Before operating a pipeline the command fuels engineer or his delegated representative should consider the following 2.4.3.1. Secure all plans system diagrams and information possible to find the location and function of all components especially valves in the system. Some installations may require a complete engineering study to secure sufficient information for O M. 2.4.3.2. Reports should be made to decide the necessary manpower for each installation. Personnel selected should have experience in the type of equipment they will operate. Skilled engineers electricians mechanics and pump operators are usually required at each pumping station. 2.4.3.3. Inspect all equipment in the pipeline system to ensure proper working condition. Failure at one pumping station can cause a complete shutdown of the entire pipeline. 2.4.4. Off-Base Piping System Inspections 2.4.4.1. Leak Detection. Pressure checks volume checks line patrols and leak detection apparatuses may be used to detect leaks. 2.4.4.2. Pressure Checks. Pressure-check off-base piping systems annually in the same way prescribed for on-base piping systems see paragraph 2.3.3.1 . Hydrostatically test new piping systems in accordance with API RP 1110 Pressure Testing of Liquid Petroleum Pipelines. Hydrostatically test systems to the lesser of 1.5 times the operating pressure or 1.896 megapascals 275 pounds per square inch gauge maximum. During testing disconnect system components such as .
