Stork's Hot Bolt Clamp prevents $8 million deferment cost
The Client identified two flanges with severely corroded bolts at its facility in the Southern North Sea. Stork was contracted to remove and replace the four-bolt flanges on the vent system without disruption to the plant.
The plant was sea-facing and the saltwater atmosphere had caused severe corrosion of unprotected steel structures and components, resulting in corroded bolts on both upstream and downstream flanges.
Stork’s Hot Bolt Clamp (HBC) system was mobilised from the local SNS base in Lowestoft. The innovative technique allowed the corroded bolts to be removed and replaced without depressurising or isolating the plant, which is time-consuming and costly.
“I would like to take this opportunity to express my sincere thanks to the team for the excellent service provided. The service and skills was first class and a credit to themselves and Stork.”
