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.
A Possible Rival to the Panama Canal
Nicaragua recently granted a 50-year concession to Hong Kong based HKND Group, led by Chinese telecom executive Wang Jing, to cut a channel between the Caribbean Sea and the waters of the Pacific. This channel would rival the Panama Canal with the added benefit that the proposed passage through Nicaragua would be wider, and leave the country well placed to capitalize on a predicted rise in global shipping over the next twenty to thirty years. The argument for the canal is that even with its current expansion, the Panama Canal will still be too small to accommodate the world's largest container ships. In addition to the canal, the HKND Group has won rights to build a railroad, two ports, an international airport and an oil pipeline.
Pre-salt Seafloor Construction/Remote Operations Challenges Part 2
According to Petrobras production engineers, secondary recovery is increasingly being implemented to improve oil recovery in the pre-salt carbonates, where reservoir rocks are usually oil wet, and this characteristic affects the performance of water injection. Another problem concerning water injection is related to rock-fluid interaction, which is more important and complex in carbonates. In order to assess the risks involved, as well as to define mitigation actions, rock-fluid interaction tests are being carried out in the reservoir rock and the salt cap rock. Alternative recovery methods are being implemented in the pre-salt reservoirs.
OSX looking at building drill rigs for Petrobras
With the work on its new shipyard underway, OSX, the shipbuilding and ship rental company belonging to the EBX Group, is planning on entering tenders in order to try and get a piece of the contracts for 21 drillers for Petrobras. The OSX shipyard is being built within the Açu Port area (the Açu Port is also in construction and is also owned by the same EBX Group). Sete Brasil is administering the construction of the 21 drillers, which will then be leased to Petrobras. Petrobras itself will oversee the tender process. Sete Brasil is one of the local companies participating in the tender and they have already been awarded the contract for construction of the seven first drillers, which are being built at the Atlantico Sul shipyard in the Brazilian northeast state of Pernambuco.
Rig Module Hub in Bahia
The Brazilian northeast state of Bahia will house various construction yards and shipyards dedicated to rig module construction, such as jackets and floats.Accompanying the growth in ship construction in the Brazilian northeast states, the tropical state of Bahia is showing a marked increase in shipbuilding investments. Along the “Baía de Todos os Santos” or Bay of All Saints, various yards are being built to compete for rig module orders. The major client will undoubtedly be Petrobras, but there are expectations that as the yards increase their efficiency, other national and foreign O&G players operating in the Brazilian offshore will also become interested in placing orders to these new yards.
New Rig Module Construction Yards for Maritime Complex in Bahia
Four new construction yard foundations are being built in the Aratu Bay inside the Bay of All Saints (Baía de Todos os Santos), in the state of Bahia.The four new yards will build offshore rigs modules and the complex is expected to open a total of 4,000 work positions for the local workforce. The state maritime and port industry secretary commented that there is a need to invest in workforce training or there will be an invasion of workers from other states. Steps are being taken by the State and Federal Government to qualify workers, such as welders, painters and technicians to man the yards. The new yards will be run by four different companies, Belov Engenharia and GDK from Bahia, Multitek from Minas Gerais and Niplan from São Paulo.
