Mammoet’s PTC 200-DS ring crane ensures time-efficient and cost-effective approach to Petrobas P-76 FPSO-vessel construction
On March 16, 2016, Mammoet Brazil
and the Consortium Techint-Technip
(CTTP76) signed a contract for the integration of 20 modules to be lifted onto the hull of the Petrobras
P-76 FPSO (Floating Production, Storage and Offloading) vessel.
Mammoet said both parties worked closely together over the past months in anticipation of the exact integration schedule which was dependent on delivery of the hull. With the hull delivery date now confirmed, Mammoet Brazil and CTTP76 will proceed with the project execution. Integration of the modules is scheduled to start in June or July 2016.
Mammoet will weigh, transport and lift the modules ranging up to 1,935 metric tons. “For this extreme heavy lifting task Mammoet will mobilize its PTC 200-DS which is currently in the U.S.A.,” said Michel Booden, Sales Director for Mammoet Latin America. “The PTC 200-DS, of which we own three, is our largest ring crane. It has already executed the successful integration of FPSO-modules in the past here in Brazil.”
The unique design of the PTC 200-DS ring crane makes it suitable for the fast and efficient integration of modules onto an FPSO-vessel. The crane’s long reach, small footprint and capability for 360 degree turns enable it to pick up and place all modules from one location on the quayside. Because it can be broken down into parts the size of standard shipping containers the PTC 200-DS can be quickly transported from the U.S. to Brazil – ensuring time-efficient and cost-effective mobilization.
The whole operation will be supported by 78 axle lines of SPMTs (Self-Propelled Modular Transporters) and highly accurate weighing equipment to determine the exact weight and center-of-gravity of each module before lifting. The integration work will be executed at the Techint offshore yard UOT (Unidade Offshore Techint) in the city of Paranaguá in Paraná State, Brazil.
