The exploration and production of deepwater pre-salt plays offshore Brazil have triggered major technological challenges. Some reservoirs are located under 2,000 meters of water and have to be drilled through another 2,000 or so meters of salt. Although exploration challenges have been daunting, production challenges are no less formidable. With a number of production and injection wells placed over the large reservoirs, the difficulty of reliably and safely bringing the oil and gas to production FPSOs have been compounded by the extreme water depths involved.In 2011 Subsea 7 was awarded a milestone

The vertical range of this collection of measurements - called a profile of ocean current velocities - is greater for lower frequency sound waves.   Introduction Thanks to a spirited cadre of marine scientists and engineers, high-tech ocean observatories are now operational. These sites provide a continuous presence in the ocean for sustained and interactive observing. Many combine innovative infrastructure with multi-discipline marine sensors.   Installed at various depths, these observatorie

GustoMSC Evolves Chela the "Smart" Crane

Nearly two years ago GustoMSC introduced a smart crane for lifting and wireline operations under the drilling cantilever. Two years later, following industry feedback and further development, the equipment has evolved into Chela, named after the Greek word for a crab’s claw. Chela offers an extra hand in operations, and due to its crablike motion characteristics, it can reach below the cantilever as well as elevate towards the main deck, providing crane access to an area traditionally blocked by the cantilever when drilling.   Three key elements to enhance the overall efficiency of the
