Jack-up and skidding operations for the Malikai Project, Malaysia

Overview

ALE has jacked-up the Malikai Topside 40m high, before skidding the Topside a distance of 90m whilst at this elevation – making these the world’s highest jack-up 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.

ALE first weighed the Topside using weighing cells. The Topside weighed in at 13,800t and was skidded 90m onto ALE’s Mega Jack using ALE’s skidding system.

The Mega Jack jacked-up the Topside to a height of 40m – the world’s highest ever jack-up on this scale. When jacked-up, the Topside weighed a combined total of 17,300t.

The Topside was then skidded a distance of 90m at elevation, until it was above the Hull. ALE then mated the Topside with the Hull.  As both the Mega Jack and skidding systems are operated remotely via a control room and are equipped with computerised 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. ALE was also contracted to remove all equipment using ALE’s 900t strand jacks (preinstalled onto the main deck of the Topside), skidding equipment and SPMTs.

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 optimising the logistics needed for such a build.

Because the equipment is easy to mobilise 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.

The final stage of the project involved the load-out of the Tension Leg Platform (TLP).
