The development of a consequences database requires a description of the damages that occur in the incidents-accidents that result in fires and/or explosions. In order to determine the consequences of an incident-accident, the records of the National Transportation Safety Board ("NTSB") wer examined for relevant information (such as description of the damage) since that tyep of data does not exist in the PHMSA database. The consequences database was then used in conjunction with a sample Geographic Information System ("GIS") developed by the project team. The damage area found in the consequences database was analyzed using a GIS to determine the damages that would result if an incident were to occur at various locations along the simulated pipeline in the GIS.

The primary objective of Phase IV is to extend the current ALPIS capability to the detection of volatile emissions from liquid transmission pipelines.
The Airborne LIDAR Pipeline Inspection System (ALPIS) is an airborne remote sensing system for detecting leaks associated with natural gas and hazardous liquid pipelines. Data collected with ALPIS can be incorporated into a geographic information system (GIS) to create mapping databases. Project goals are to achieve survey speeds of up to 150 miles per hour and cost equal to or less than much slower survey methods currently available.

ITT is extending its ANGEL (Airborne Natural Gas Emission Lidar) technology to the detection of small hazardous liquid and refined product leaks. The ANGEL system is designed to remotely detect, quantify, and map small plumes of methane and ethane, the principle constituents of natural gas. In addition to the hardware and software systems, ITT has developed expertise in the spectroscopy, modeling, and empirical/physical testing and validation of airborne dispersed hazardous vapors. These tests have yielded preliminary results that indicate the detection of vapors from hazardous liquids is possible with minimal changes to the existing ANGEL system.

The objective of this project is to develop, demonstrate and commercialize a system that utilizes GPS technology to allow one-call centers and utility companies to ensure that excavation activity does not encroach upon underground facilities. The developed systems will be demonstrated in a pilot program with Virginia Utility Protection Services and NiSource to assess the costs, benefits and feasibility of the system. Trimble and Metrotech are commercial partners for this program.
