ALE’s SK350 crane is performing lifts on a major oil and gas expansion project in Canada. The design of the crane has enabled it to continue operating in the area’s high wind speeds and across a live construction site.
The West White Rose Project involves the installation of an offshore platform, consisting of a concrete gravity structure (CGS) and integrated topsides. The construction of the CGS, measuring 145m high and weighing over 200,000t in total, is taking place in Argentia, Newfoundland.
The exceptional capabilities of the SK350 heavylift crane led to ALE and the client working together to design a solution that would maximise efficiency and minimise disruption on site, ultimately saving time and costs for the project.
ALE is lifting a variety of components that weigh up to 221t and measure as large as 36m x 36m. The lifts themselves are complex as they cross a live construction site and must negotiate numerous obstructions, including other cranes.
The SK350 has been assembled in its largest ever configuration, enabling it to perform lifts with over 200m of outreach. This outreach, combined with the crane’s heavylifting capabilities, ensures it can lift the components as modularised assemblies from fabrication areas around the site.
Operating from a single location, this enables ALE to lift the modules, rotate 180°, and set them down up to half a kilometre away from their original position. The modules can be lifted directly into their final position, expediting the construction schedule.
