ALE connects Malikai TLP modules for transport

Offshore staff

KUALA LUMPUR, Malaysia -- ALE has jacked-up and skidded the topsides for Shell’s new Malikai tension leg platform, due to be installed 100 km (62 mi) offshore Sabah.

The contractor performed the work on behalf of the Technip/Malaysia Marine and Heavy Engineering (MMHE) joint venture at the latter’s West yard in Johor Darul Takzim, Malaysia.

ALE’s scope comprised weighing and transporting four unit hull blocks, living quarters and mega beams for the lifting program; weighing of the topsides and subsequent skidding and jacking up; and finally skidding at height of the topsides over the hull and mating of the two structures.

In April ALE began setting up equipment for the lift campaign including its computer-controlled skidding system, ALE mast system, Mega Jack system, weighing cells, and strand jacks.

The 13,800-ton topsides was skidded 85 m (279 ft) onto the Mega Jack system, which jacked the topsides up to a height of 40 m (131 ft) – claimed to be the highest ever jack-up operation on this scale.

ALE then skidded the topsides 90 m (295 ft) at elevation until it was above the hull, followed by mating.
