Oil pipeline transmission systems are linear targets that attract attacks from an adversary primarily because of two factors. The first is the low risk to attacking forces. Since they are so spread out, they are difficult to protect. The second is the potential for high payoff. Pipeline broken in a location where it is difficult to repair or where it causes massive collateral damage may meet the goals of the adversary. The ideal way to prevent attacks is to raise the risk of an attack for the adversary while simultaneously lowering the potential payoff. The principles of the Physical Security System (PSS) apply to the protection of any pipeline transmission system. A PSS protects by using layered technology, barriers and human resources to detect the adversary, delay the adversary in or near the target, and allow sufficient time for security forces to respond in sufficient numbers to interrupt and ultimately destroy the adversary. The integration of Intelligent Imaging Incís. electro-optical technology, sophisticated sensors, and local personnel can provide oil pipeline transmission systems with better assessed detection of adversaries and ultimately result in swifter, more effective response by local security forces to defeat the adversary.
