Keppel Offshore & Marine (Keppel O&M) confirmed late Wednesday that it has delivered the mammoth topsides module of the P-61 Tension Leg Wellhead Platform (TLWP) to its subsidiary, BrasFELS shipyard in Angra Dos Reis in Brazil.
"Completed on schedule with a perfect safety record at the Keppel FELS yard in Singapore, the topsides module was transported Oct. 27 on a carrier over 6,835 miles (11,000 kilometers) to BrasFELS for the integration phase," the company said in a statement.
The P-61 project was won in 2010 by FloaTEC, a joint venture (JV) between Keppel FELS and McDermott, from a Papa-Terra JV consisting of Petrobras and Chevron.
The scope of work includes Keppel FELS and BrasFELS constructing the TLWP, FloaTEC supplying the risers, well systems and tendon components and McDermott fabricating the tendons, temporary buoyancy modules and piles and providing topsides engineering and procurement services.
When completed, P-61 will be the first TLWP in Brazil, and it will be deployed to the Papa Terra field in the Southern section of the Campos Basin at Exploratory Block BC20.
The Papa Terra field – discovered in 2003 by five wells – lies in 3,937 feet (1,200 meters) of waters and holds potential recoverable oil volumes ranging between 700 million and one billion barrels of oil equivalent. Papa Terra's crude reserves are estimated to have an APR index between 14 and 17 degrees. The extreme water depth, the high viscosity and the low API were major factors when the operator was considering how to develop the field.
Petrobras is the operator of the giant field with a 62.5 percent interest, while Chevron holds the remaining 37.5 interest.
