PSC Heavy Lift and Van Seumeren are each claiming world records for heavy lifting feats.
In early September PSC lifted an 11,000t load 38m up into the air, using strand jacks. This, it is being claimed, is the heaviest lift that has ever been carried out.
Meanwhile, Van Seumeren of the Netherlands has claimed a world record for the heaviest load lifted by a single body crawler crane. On 23 August it lifted a 1,359t vessel with its 2,000t capacity Mannesmann Dematic CC 12600 at a refinery in Texas.
PSC’s lift took place at the fabrication yard of Hyundai Heavy Industries in Ulsan, South Korea. The load was the RBS-8M semi-submersible deck known as Deepwater Nautilus, owned by R&B Falcon.
Working for Hyundai, the British specialist used 24 of its L600 strand jacks, supported by a set of six temporary lifting towers, to raise the deck 38m. The deck was raised so that the two lower hull sections could be skidded underneath. PSC also supplied an active loadout system to complete the semi-submersible structure.
Next month PSC loads out the complete 25,500t semi-submersible over a distance of 120m using eight of the strand jacks.
