Mammoet’s SK6000 has passed its test programme after Lloyd’s Register certified the crane’s safe operation to its specification.
Lloyd’s Register initially confirmed that Mammoet’s test programme was suitable to prove out its capacity charts earlier in the model’s development, with testing then carried out at Mammoet’s Westdorpe facility in the Netherlands over the past three months.
A thorough functional test programme verified the crane operated to its specification, and to the most rigorous safety standards.
Structural and stability testing followed, with the SK6000 subjected to a range of lift weights and conditions, to prove that all components withstand 125 percent overload. The maximum extents of all load charts for the crane were tested, for all main mast configurations, from shortest (127 m) to longest (171 m).
The SK6000 was tested to a maximum load moment of 520,000 tonne m, which is more than one-and-a-half times greater than the rated load moment of Mammoet’s SK350.
Particularly beneficial for the energy sector, the SK6000’s jib can be fitted to enable lifts of 3,000 tonnes to 220 m. The model reduces on-site construction time and increases safety by allowing larger mass components to be constructed in controlled conditions and assembly quickly, which lends the crane to the nuclear sector. In oil and gas, its large capacity and outreach allows maintenance and upgrade projects to occur with less disruption.
The SK6000 will now be boomed down and containerised, ready for shipping to its first project in early 2025.
