In the construction of Northwest Refining’s Redwater Refinery, the heaviest vessel to be set was the 1,450 tonne Cracking Reactor. Installing this vessel was a key milestone in the project, and posed the crux of early construction activities.
Setting this vessel with a crane was not possible, so another solution was necessary. Craig, with a former employer, was part of the team that designed and engineered a lift system structure to lift the vessel into place.
The slender structure was unguyed – a unique cost-savings that allowed construction activity to take place around the structure during its assembly and operation. Where guy lines would have restricted overhead activity, this structure posed no such limitations. The lift system solution reflected a cost savings through reduced ground work, equipment costs, and a minimal footprint.
