Mammoet sets push-up records

A contract to push-up a newly built offshore deck at a production site in Ulsan, South Korea, set two push-up records, claimed Mammoet. The international heavy lift and transport specialist claimed the record for a total weight of 23,179 tonnes and for a total height of 26.485 metres.

The Mammoet push-up system is designed to withstand winds up to 20 metres per second. The client, however, asked Mammoet to modify it to withstand 30 m per second, as the actual push-up date was close to the end of the typhoon season.

The company mobilised 15 of its 16 push-up towers and produced additional jacking cans and bracing pipes. Some 153 containers of equipment were brought to the site from around the world.

In a combined effort by Mammoet and the client, the deck was picked up from its temporary construction supports, weighed with the push-up system and brought to a new record height of 26.485 m, says the company. "This only took us seven days. In the following two days, the client positioned the load-out frame underneath the deck and Mammoet lowered the deck onto the frame," says a company spokesman.
