ABS to perform first TLP dry tree application for Petrobras

ABS has been selected to class two of the major components in Petrobras' Papa Terra offshore Brazil field development. ABS will provide support on Petrobras’ tension-leg wellhead platform (TLWP) known as P-61, which will be the first-of- its-kind TLP dry tree application to be installed in deepwater offshore Brazil.

The P-61 and floating production, storage and offloading (FPSO) unit P-63 will both be ABS classed.

Houston-based FloaTEC designed the TLWP which will be built at Keppel's BrasFels yard in Angra dos Reis.

The P-63 will join many other ABS-classed FPSOs operating offshore Brazil. The unit is a conversion of a very large crude carrier (VLCC) and, when completed, will have 16 topside modules weighing over 14,000 metric tons. The facilities on board are designed to process approximately 140,000 barrels per day of oil and 35 million standard cubic feet of gas per day.

ABS will work closely with Brazil's QUIP consortium facility in Rio Grande during the fabrication and integration.

ABS' scope of classification for an FPSO includes: review and approval of the FPSO design for compliance with ABS Rules, survey of fabrication components in the field to facilitate compliance with ABS Rules, verification that the hull structure, mooring systems and foundation, marine, production, utility and safety systems comply with the relevant standards, as well as survey of the offshore hook-up and commissioning.

A third major component for the field's development is a tender-assist rig. The rig will be used to drill and intervene on development wells working from the TLWP.

The Papa Terra heavy oil field is located in the Campos Basin approximately 110 km (68 miles) off Rio de Janeiro in water depths of up to 1,200 meters (3,940 feet). Petrobras and partner Chevron are slated to put the field into production by late 2013.
