Challenge
The base below a coker at a refinery in the Oil Sands needed to be repaired in order to stabilize the foundation. In order to perform the base repair maintenance the massive vessel needed to be lifted approximately 100 mm. Lifting a vessel weighing 600 tons, 9m in diameter and 40m tall required a solution with a high degree of safety, capable of maintaining the balance of the load throughout the lift.
Solution
The Integrated Solutions division of Enerpac worked closely with the local distributor, HyPower Systems, and the site contractor to design a system to lift the coker with the highest degree of safety. To ensure operation in cold temperatures a custom synchronous lifting system was developed. The lift system included eight CLRG high tonnage hydraulic cylinders with stroke sensors and custom cold-weather cables, manifolds, load holding valves, artic hydraulic oil and a hydraulic power unit. HyPower Systems on-site training, supervision, and 24 hour technical support, along with close collaboration with Enerpac ensured the custom synch-lift system completed the lift successfully.
