No-Dig Point Repair Technology for Steel O&G Pipelines

PHMSA reports a total of 5,745 pipeline incidents with 282 deaths and 1,193 injuries in the 20-year period from 2000 through 2019. Moreover, these incidents cost $10,419,311,449 in damages. Most oil and gas (O&G) transmission pipes are repaired externally by excavating around a damaged or leak site, preparing the pipe surface, and mechanically installing a repair product such as a clamp or wrap on the outside of the pipe. The available repair methods are disruptive, require access by destructive means and are costly in terms of time and resources.The SuperLaminate® technology offers a high-strength, no-dig steel transmission pipe repair technology to prevent such failures proactively. The technique can also be used to repair leaking pipes with burst holes, cracks, etc. SuperLaminate® has the potential to be installed without the need for any excavation and accessing the pipe bynon-destructive means utilizing launch stations used for cleaning and inspection of O&G pipes. Our main objective in Phase I is achieving proof of concept with respect to using the technique for steel transmission pipes. To achieve this objective, we will be testing the system for high pressure and chemical resistance, thereby developing a design methodology for such applications.
