I came across an article that mentions an innovative solution to replace flange bolts online.
The article mentions that "Stork’s technology hydraulically clamps pressurised 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 de-pressurised and removed. Change out of the bolts is achieved without taking the flanges out of operation, disruption to the standard line pressure or danger of hydrocarbon release".
I am not endorsing the product but you can read more about it in this link.
