CISBOT Travels Under Iconic George Street in Scotland Repairing Gas Infrastructure

US-Based ULC Robotics’ CISBOT Robot is Deployed Underground for UK Gas Utility SGN

ULC Robotics, a leading robotics, energy services and research and development company focused on the energy and utility industries, has deployed its Cast Iron Joint Sealing Robot (CISBOT) for the first time in Scotland on iconic George Street in Edinburgh. Similar to Fifth Avenue in New York City, the visitors and high-end shop owners along George Street are not likely to notice CISBOT because the robot is virtually invisible.

In conjunction with UK gas distribution network SGN, CISBOT will carry out advanced maintenance in more than 1,965 feet of gas pipe that delivers gas to businesses and residents in one of the city’s most high profile and central locations. Unlike traditional methods of rehabilitating or replacing cast iron gas mains, ULC’s CISBOT robot enters the live, large diameter cast iron gas mains through small excavation and the robot’s advanced technology enables it to repair joints while minimizing disruption to the public.

“In George Street, we’ll be carrying out maintenance on around 1,965 feet of gas pipe. The work will take around six weeks, however the use of this technology will make a difference in minimizing disruption, as we will only need to make two excavations in the road,” said Matt Ferguson, Team Manager for SGN. “In fact, 96% of our work will be unseen as it will take place under the ground.”

By using ULC’s CISBOT robotic technology on George Street, the non-intrusive work performed on live gas mains means that many businesses along the busy section of the street benefit because their gas services remain intact and online during the procedure. Furthermore, the work done with CISBOT reduces the risk for gas leaks and because there are no large-scale excavations, greenhouse gas emissions are greatly reduced.

“Gas utilities in the United States and in the UK are dedicated to making pipeline safety and reliability a paramount priority,” said Gregory Penza, President of ULC Robotics. “CISBOT technology helps gas utilities, such as SGN, maintain the safety and reliability of large diameter cast iron gas mains by renewing the joints, where gas is most likely to escape.”

In addition to the George Street project, ULC Robotics performs year-round operations for SGN and now has two CISBOT systems dedicated to the gas utility’s field operations.

CISBOT is currently operated on two continents in highly populated areas including London, Edinburgh, New York City, Boston to seal joints in live gas mains.
