ALE Carries Out Jackup and Skidding Operations for Malikai Topside in Johor

International heavy transportation and lifting contractor ALE disclosed Monday that it has jacked-up the Malikai Topside 131 feet (40 meters) high, before skidding the Topside a distance of 295 feet (90 meters) whilst at this elevation -- making these the world's highest jackup and skidding operations performed on this scale. These operations were carried out whilst executing the Malikai EPC TLP Project at Malaysia Marine and Heavy Engineering (MMHE) West in Johor Darul Takzim, Malaysia.

The global heavylift specialists were awarded the contracts for the Malikai Project on behalf of TMJV. ALE was given the scope of weighing and transporting four unit Hull blocks, Living Quarters and mega beams for the 'Superlift' activities. In addition, ALE was also awarded with the weighing of the Topside, skidding of the Topside, jacking-up of the Topside, skidding at height of the Topside over the Hull and mating of Topside and Hull.

ALE started to mobilize the equipment at the beginning of April and started setting up the equipment needed for the Superlift (including its further-developed computer-controlled skidding system, ALE mast system, Mega Jack system, weighing cells, strand jacks) in May. The Superlift was then executed in July.

The Topside weighed in at 13,800 tons and was skidded 279 feet (85 meters) onto ALE’s Mega Jack system. The Mega Jack jacked-up the Topside to a height of 131 feet (40 meters) - the world’s highest ever jackup on this scale. When jacked-up the Topside weighed a combined total of 17,300 tons. The Topside was then skidded a distance of 295 feet (90 meters) at elevation, until it was above the Hull. ALE then mated the Topside with the Hull.

ALE was also contracted to remove all equipment using ALE’s 900 ton strand jacks (pre-installed onto the main deck of the Topside), skidding equipment and SPMTs (self propelled nodular transporters).

ALE’s Project Manager Edwin Blosser, from ALE’s Netherlands branch who coordinated the Superlift activities, commented: “It is fantastic to be part of a world first. At ALE we are always willing to push the boundaries in order to offer a bespoke solution for the client. In order to achieve such an operation, our engineers and crew have worked hard to carry out the necessary studies and safety checks.

“This Superlift would not have been possible without a great crew and the Mega Jack System. With its capacity to easily lift the Topside to the desired height, the Mega Jack enabled the client to work on both the Topside and the Hull on ground level, therefore optimizing the logistics needed for such a build. As both the Mega Jack and skidding systems are operated remotely via a control room and are equipped with computerized controls, which have numerous safety systems implemented, these provided a safe way of working and protected both workers and the client’s equipment being lifted. Because the equipment is easy to mobilize and handle, ALE was able to install within the deadline set by the client and despite the challenges ALE faced on-site, the Superlift was completed without any delay to the project.”
