Subsea 7 Claims That the Pipes Double the Strength Factor
In October, a second order was placed for about 73 km (45 miles) of mechanically coated BuBi pipes (10-inch OD) and 4,200 m (13,779 feet) of metallurgically coated pipes (14-inch OD). The pipes were ordered in a combination of carbon-manganese steel and corrosion-resistant alloy materials.
According to Subsea 7, the use of clad materials in pipe manufacturing combines the strength and toughness properties of carbon-manganese steels with the corrosion resistance of stainless steels. Located about 185 km (115 miles) off the coast of São Paulo, the Bacalhau oil field is in the pre-salt Santos basin at approximately 2,050 m (6,726 feet) of water.

Bernd Harborth and Berni Reimer, project managers for coated pipes at Subsea 7 for the Pre-Salt, said: “The pipes are subjected to high tensile loads due to the water column of 2,050 m. To withstand these conditions, maximum options for wall thicknesses, dimensional tolerances, and material properties will be utilized during production.”
