ULC Robotics, Inc., a leading robotics, energy services and research and development company focused on the energy and utility industries, has deployed its advanced Cast Iron Joint Sealing Robot (CISBOT) technology into a live, large diameter cast iron gas main for National Grid in the Bay Ridge area. Unlike other methods of rehabilitating or replacing cast iron gas mains, ULC’s CISBOT technology enables gas utilities to repair leak-prone joints while minimizing excavation and disruption to the public.
ULC’s CISBOT seals gas mains by internally drilling and injecting each joint with a sealant using a method that has been proven by Cornell University studies to last for 50 years. The robot enters the gas main through a small excavation to seal up to 1,500 feet – or three average city blocks – of gas main line from that single excavation.
By using ULC’s CISBOT technology, non-intrusive work performed on live gas mains means local residents and businesses benefit because their gas services remain intact and online during the procedure without costly and disruptive shutdowns. ULC’s advanced robotic system makes quiet work of critical repairs to National Grid’s gas distribution system.
“Gas utilities go to great lengths to make pipeline safety and reliability a top priority,” said Gregory Penza, President of ULC Robotics. “CISBOT technology helps gas utilities such as National Grid maintain the safety and reliability of large diameter cast iron gas mains by renewing the joints, where methane gas is most likely to escape.”
While this deployment of CISBOT at the intersection of 64th Street and 17th Avenue in Brooklyn, New York, marks the first deployment of this robotic technology for National Grid in New York since 2010, the gas utility has been consistently using CISBOT to seal joints in the Boston, Massachusetts operating area since 2011.
