Pre-salt Seafloor Construction/Remote Operations Challenges Part 3

October 15, 2014

USA FMC Technologies Reaches Record USD bln of Subsea Revenue in
With the experience Petrobras has gained in deepwater field construction, the national operator has learned the best ways to get the job done and who to work with. Much of Petrobras’ deepwater seafloor construction work has been done by DOF, Technip, Subsea 7, FMC and Aker. Large deepwater post-salt fields such as Roncador, Frade and Marlim amongst others have been the main testing grounds of many construction techniques and much of the equipment being installed. Obviously, experience in deepwater seafloor construction has also been gained by Petrobras and service providers in locations such as the GoM and West Africa. Most of the pre-salt subsea trees will be built and installed by FMC, OneSubsea and Aker. FMC has a total order worth $1,5 billion, which was announced in March of 2012.

Ballast control systems are a vital part of semi-submersible oil platforms. The ballast control system is made up of a network of pipes, valves, pumps, and tanks, which work as a liquid control system to keep the vessel at an even keel. Offshore drilling is an extremely risky undertaking, which is susceptible to accidents, which may cause human casualties and environmental disasters. One of the key systems necessary to keep oil rigs afloat, is the effective design of the user interface for the ballast control system, which significantly contributes to overall safety of a rig’s crew and the environment. The threat of disaster is the main reason to provide the operators with the most effective ballast control system possible. One such disaster occurred in 2001 aboard Petrobras’ P36 oil rig.

Saipem is also specialized in providing engineering, procurement, project management and construction services. In 2010 Saipem was awarded by Petrobras the EPIC contract for the P55-SCR project, encompassing the engineering, procurement, transportation and offshore installation of flowlines and risers serving the semi P-55 to be installed in the Roncador field, in the Campos Basin, off the coast of the Rio de Janeiro State, in Brazil. For this contract Saipem will be working with companies specialized in subsea construction, such as Advanced Subsea and others, while utilizing various subsea support equipment, such as AUVs and ROVs.
