Stork Technical Services has launched a hot-bolt clamp system that enables the safe removal and replacement of corroded bolts on live flanged connections that have eight bolts or fewer. The company said the system has been field-tested and was successfully used on a Chevron North Sea-operated asset in the North Sea. The system hydraulically clamps pressurized bolted pipeline flanges together so that corroded stud bolts can be safely removed without exerting additional force to the gaskets. Once all of the bolts have been replaced, the hot-bolt clamps are depressurized and removed. Changing of the bolts does not require taking the flanges out of operation, avoids disruption to the standard line pressure, and minimizes the danger of hydrocarbon release.
