Carbon Fiber for Deepwater Umbilicals
The umbilicals in the oil and gas industry are the lifelines of deepwater O&G fields, connecting wells to the offshore platform. The use of carbon fiber rods to replace some of the steel sheathing is an interesting development for use in deepwater umbilicals.Since the 1990s, subsea production systems have become increasingly important, specifically for deepwater plays. Some wells or well systems are located as far as 100 km from the production rig and may be up to 3,000 meters deep. As a result, umbilicals composed of steel tube conduit, thermoplastic hose, or a combination of the both, are critical for power, control, communication, and fluid injection to keep deepwater wells working efficiently and producing continuously.
Aker on Managed Pressure Operations
When Aker Solutions acquired Managed Pressure Operations in 2013, it became a provider of next generation continuous circulation and managed pressure drilling (MPD) systems, which has become a critical component to the drilling process going into the future. MPD systems have proven to be reliable, enabling maximum up time and significant cost savings and has been labeled of strategic importance for pre-salt drilling by Brazilian operator Petrobras, which uses MPD systems developed by Weatherford, which was the company that first introduced large scale use of the system to the industry. The MPD system being introduced by Aker/MPO is fully automated and simple to operate, needing few people to run the equipment.
Deepwater Remote Operations Challenges
Today, much emphasis is given to working with real-time production data, real-time pipeline monitoring, leak detection and equipment condition monitoring. ROV/ AUV operations are used to support all sorts of deepwater seafloor construction processes, allowing operators to continuously monitor their subsea systems and intervene when necessary. Basically all equipment being installed on the seafloor has real-time communication systems, which allow operators on the surface to monitor the equipment’s performance and even control much of the equipment from the surface. Equipment that can be monitored from the surface but which cannot be manipulated remotely…
Pre-salt Seafloor Construction/Remote Operations Challenges Part 3
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.
Aker Solutions Showing High Subsea Product Diversity in Brazil
With major subsea contracts signed with Petrobras in 2009, the future looks bright for Aker Solutions and their range of subsea products and solutions in Brazil.In November 2009, Aker Solutions do Brasil signed two contracts to supply subsea connection systems for the P-55 platform, which will operate at the Roncador field offshore Brazil. The contracts were signed with Petrobras and Subsea 7. For Petrobras the contract involves three Plets (pipeline-end termination systems), two rigid jumpers, tools and accessories. For Subsea 7 the contract involved two sets of 12" Plets, one set of 12" ILT (t-shaped pipeline), tools and accessories. The values for each contract were not disclosed.
Brazilian Subsea Equipment Market Views
With an eye on the lucrative subsea equipment market, suppliers are investing in technology, local workforce and expanding local facilities. New Brazilian companies specialized in subsea equipment and services also strive to compete with foreign suppliers.Today Petrobras is one of the greatest if not the greatest subsea equipment buyer in the world. With the ongoing discoveries of new deepwater and ultra-deepwater O&G plays in Brazil´s offshore, there is a sustained demand for essential subsea systems such as BOPs, Christmas trees, subsea manifolds, risers, rigid and flexible flowlines, umbilicals, subsea control and monitoring systems, ROV´s, AUS´s and all manner of subsea support systems.
