Remote Control Valve (RCV) / Automatic Shutoff Valve (ASV) Studies
A Remote Control Valve (RCV) is a main line valve that can be operated from the SCADA control room, making it a much faster method of stopping the flow to a break than driving to a manually operated valve. An Automatic Shutoff Valve (ASV) is a main line valve that would automatically close when a line rupture is detected based on certain flow/pressure conditions, reducing the flow of gas to the break. Regulation requires operators to determine, based on a risk analysis, whether an ASV or RCV would be an efficient means of adding protection to a high consequence area in the event of a gas release.
We have helped several of our clients complete analyses that include a detailed model of a failure and the resulting heat flux to estimate the radii at which damage to personal and/or commercial property would likely occur. We have experience estimating costs associated with damage at the hypothetical rupture relative to the savings / costs of installing an ASV/RCV, and the resultant benefit to public safety (if any). The analysis helps our clients make an informed decision regarding the benefit and appropriate location of an RCV or ASV.
