“Careful

and crews”
Successful push-up performances
Early 2009 was a busy time for the jack, strand jack and ballast equipment and crews in
Asia. We worked at three shipyards, in Singapore and Batam, which required careful
scheduling of the equipment and crews.
Within four months we undertook:
• three weighing and jack-up jobs (9,000 -14,000 tons) using the 2,400 ton heavy jack-up
system
• four load-outs (14,000 - 18,000 tons)
• six pulling and jacking operations using strand jacks and climbing jacks (3,000 - 5,000
tons)
In Singapore we launched the pontoons of a semi-submersible drilling rig and then
skidded the 12,000 ton upper hull onto the pontoons. For the next rig we also jacked the
upper hull up to 16.5 meters.
In Batam we weighed a topside with 32 x 600 ton jacks and loadcells. We then loaded
the 15,400 ton structure out using four 900 ton strand jacks and 36 ballast pumps, each
with a capacity of 1000 m 3 /h.
We finished with the jack-up and load-out of the MDPP topside in Singapore. It was first
weighed and jacked up to 12 meters using 12 x 2,400 ton jacking towers. By the time it
was loaded out the weight had increased to 18,000 tons and we used six 900 ton strand
jacks to move it onto a semi-submersible.
