Final voyage for Pluto-bound Jumbo vessel

02 December 2009

Jumbo Shipping's heavy lift vessel Daniella has completed its eleventh and final voyage for the Pluto LNG project in Dampier, Australia.

Between October 2008 and October 2009 Daniella transported 256 pieces of equipment for the project, including pre-assembled structures and pipe racks weighing up to 240 tonnes. Jumbo heavy lift vessel Fairlift has completed 12 voyages and will start the final phase of another five shipments.

The Pluto LNG project in Dampier is developed by EPC-contractor Foster Wheeler WorleyParsons (FWW) for Australian energy major Woodside. The project comprises the installation of five subsea production wells connected to an onshore LNG processing train (plant) to be constructed on the Burrup Peninsula LNG Park near the port of Dampier.

Jumbo was contracted for the shipment of the pre-assembled modules for the onshore LNG train. These modules, with typical weights between 25 and 240 tonnes, consist of pre-assembled pipe racks and other LNG processing equipment. Loading from Laem Chabang Port and Port Sattahip (Thailand), Port Klang (Malaysia) and the port of Melbourne (Australia), HLV's Daniella and Fairlift have been working continuously for this extensive project.

Challenges

The Puto LNG project is challenging in many ways: logistically, from the engineering perspective and from an operational point of view. The project will be developed in a record time of five years, with discovery of the gas field in 2005 and planned production of first gas in 2010. In this tight schedule on-time delivery of the modules is important.

Since the construction site offers little storage space, the pre-assembled units have to be shipped in the correct sequence at the right time. Dampier's draught restrictions bring another challenge. To be able to discharge always, a crucial condition for this project, the ships are allowed a maximum draught of 5.30 m.

That is why Jumbo selected its E-class vessels. With their high level of stability and shallow draught they can be fully loaded in these limitations, said Jumbo. Flexibility is key and sometimes the designed stowage and lifting plans are adjusted at short notice to cope with last minute changes.

These conditions require much co-operation and trust between Jumbo's engineers, the client and the ships' crews. Having met the challenges, the first phase, numbering 23 voyages, has been completed without a flaw. Completion of the second and final phase is expected in april 2010.
