Hot Bolt Clamp

Safe replacement of corroded bolts

Safe replacement of corroded bolts on live flanged connections with no disruption to ongoing production

In direct response to industry safety concerns regarding uncontrolled pressure releases due to stud bolt failures and potential releases due to severe stud bolt corrosion, Stork embarked on a rigorous research, design and testing program to develop the industry-first Hot Bolt Clamp (HBC) technology.

We identified a significant cost, time and safety issue for all offshore clients whereby restrictions on the live hot bolting of 4 bolt flanges forced clients to tackle such systems only during specific shutdowns, a costly and time consuming activity.

Starting from a blank sheet, a bespoke clamping system was conceived and developed over a number of years. Extensive in house testing was followed by diskussion with prospective clients for an opportunity to field trial the system.

Since its launch in 2012, our patented and award winning Hot Bolt Clamp technology has revolutionized integrity management of bolted connections, this innovative technology enables the safe removal and replacement of corroded bolts on live flanged connections that have eight bolts or less, with no disruption to production.

Stork continue to deliver bottom line benefits to our clients with our innovations and an impressive track record and industry recognition has clearly been established. Please read some of our HBC innovation testimonials.

How we add value

Uninterrupted production

Corroded bolts replaced on live flanged connections with no disruption to production, removing the requirement for a costly shutdown.

Cost reduction

The technology can be used on live assets removing the requirement for shutdowns and associated downtime, reducing manpower and bed space requirements.

Reduce releases

Reduces the likelihood of hydrocarbon releases, therefore improving the safety of offshore operatives

Improve efficiency

A four bolt flange can be reworked in only 40 minutes using HBC, delivering a significant time saving compared with traditional techniques.

Track record

Excellent track record with thousands of flanges reworked and a 100% success rate.
