Yantai Raffles completes 12,000 ton deckbox lift
China's largest offshore rig builder, Yantai Raffles Shipyard has completed the second commercial lift by its 20,000 metric ton crane, Taisun.
On Friday, over 450 international and domestic dignatories and guests watched the completion of the mating of the semisubmersible SS Pantanal as the giant crane gently lowered the massive 12,000 ton (13,227 short ton) deck box onto the hull.
With Taisun's highly sophisticated control system and the hull afloat within the dry dock, the final approach and mating was completed safely and efficiently.
The Pantanal is the first of two Semi Submersible Drilling Rigs which will be delivered to Brazil's Schahin Group.
By using Taisun during the construction of the Pantanal deckbox and hull, Yantai Raffles managed to increase efficiency dramatically saving up to 2 million man hours during the project's construction, providing large project cost savings and by bringing the construction down to ground level, greatly enhancing safety levels.
The next mating is scheduled to be the mating of the deckbox and hull of the SAIPEM SCARABEO 9 semsubmersible. With the deckbox weighing an astonishing 17,000 t, this will be the heaviest commercial lift ever recorded.
