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.
How we add value
Corroded bolts replaced on live flanged connections with no disruption to production, removing the requirement for a costly shutdown.
The technology can be used on live assets removing the requirement for shutdowns and associated downtime, reducing manpower and bed space requirements.
Reduces the likelihood of hydrocarbon releases, therefore improving the safety of offshore operatives
A four bolt flange can be reworked in only 40 minutes using HBC, delivering a significant time saving compared with traditional techniques.
Excellent track record with thousands of flanges reworked and a 100% success rate.
The Hot Bolt Clamp has been utilized successfully on the following systems:
- Aviation Fire Fighting Foam
- Air Receiver & Dryer Package
- Aviation Fuel
- Chemical Injection (biocide and inhibitor)
- Completion Fluids
- Coolant (glycol)
- Drill Water
- Fire Water System
- Hydraulic Oil
- Instrument Air
- Potable Water
- Produced Water
- Seawater Filtration
- Service Water
- Utility Air Distribution
