BISSO MARINE, a premier provider of energy and maritime support services, successfully buried a pipeline 16 feet below the hardened seabed of the Gulf of Mexico.
Working in 54 feet of water, the crew of the DLB BIG CHIEF installed a hot tap and used one of the company’s three 2,700 gpm@1,150 psi Super Jet Pump Systems to bury 13,893 feet of pipeline 10 miles off Galveston Island.
The pipeline burial was especially challenging because of the hard shear strength of the soil on the seafloor. A vane shear test showed the soil strength at 4,500 psf.
“Burying a pipeline in 4,500 psf soil is not an easy operation, especially to a depth of 16 feet,” said President and Chief Executive Officer W.A. “Beau” Bisso IV. “I am very proud of the crew of the DLB BIG CHIEF for their safe and efficient execution of this challenging project.”
The installation and burial of the 6-inch natural gas pipeline was completed on time and under budget for the client.
The FPSO Sevan Piranema has today commenced oil production on the Piranema field, off the coast of Aracaju, in the state of Sergipe, Brasil.
Q is located in Mississippi Canyon block 961. The natural gas field is developed as a subsea tieback to the Anadarko-operated Independence Hub facility in the eastern US Gulf of Mexico. StatoilHydro has a 50% working interest in the Q field.
The Piranema field, 25 km off the coast of Sergipe, started producing oil this Wednesday (10/10), in deep Northeastern Brazil waters. With operations going online in this field, Petrobras is taking another step towards maintaining Brazil’s oil self-sufficiency. The Piranema oil, of excellent quality, at 44º API, is the lightest oil produced in deep waters in Brazil.
