Jumbo offshore lifting record

Jumbo Shipping has claimed a tandem heavy lift record during the testing of its new crane transport vessel, Jumbo Jubilee.

During the August crane tests of Jumbo's latest J-class vessel at the Huisman yard in Schiedam, the Netherlands, a ballasted pontoon was lifted out of the water in tandem by the ship's two 900 tonne capacity mast cranes. A lift of 1,980 tonnes, 10% above the combined safe working load (SWL) of the cranes, was required to obtain a Lloyds Certificate of Compliance.

In this case the weight totalled 1,992 tonnes, the heaviest load ever lifted by a heavy lift transport ship, according to the company. Earlier that week, both cranes performed a full 360-degree swing with a load of 990 tonnes. Meanwhile, the ship was ballasted to a 4 degree heel angle.

Jumbo Jubilee is the fourth J-class vessel in the Jumbo fleet of 14 in-house designed heavy lift vessels and was delivered almost without a hitch, thanks to the experience gained form its predecessors, added the company.

Following final commissioning, the vessel will set sail for Brazil.
