14m High Jack-up Using the Mega Jack 800

Overview

ALE has used its award-winning Mega Jack 800 for the first time in the UK to jack-up a 954t jacket to 14m high.

Services Required

As part of a major wind farm project, the global heavylift specialists were given the scope of lifting components, performing multiple site moves, upending and jacking-up the jacket, and
loading-out the jacket and topside at the fabrication site in Lowestoft, Suffolk.

The jack-up operation took place one day after the roll-up using ALE’s AK912 and the LR1600-2. As the first of its kind in the UK, the operation involved jacking up the 954t jacket
to 14m high using a Mega Jack 800 jacking system. The suction buckets were positioned under each of the jacket legs using SPMT trailers to manoeuvre them into place. The Mega Jack 800 held it in place whilst the suction buckets were welded to the jacket by the client’s operatives.

Matthew Wooltorton, SLP Project Manager, said: “It has been a particularly complex operation to integrate the suction bucket technology into the jacket whilst also considering the construction constraints of the project. The roll-up event was a culmination of high level engineering and design works carried out by SLP and ALE and close collaborative working
with STDL to get the jacket ready for planned sail away in May.”
