GIRASSOL FPSO Project / TotalFinaElf, Angola. The Girassol FPSO (Floating Production Storage and Offloading Unit) contract for the topsides includes a DCS . While the history of floating production storage and offloading (FPSO) is paved with record cost overruns and delays, through the description of the Girassol. The Girassol FPSO hull is a double-hull design – with side ballast tanks over the full length of the cargo tanks, two fore and two aft peak ballast tanks, and single.

Yokogawa is fspo implementing the JASMIN project for an extension of the field, which involves two additional risers one line of 6 production wells and one line of 4 injection wellsgiving a total of 52 wells. Offshore Technology Conference Disciplines 4. Main tanks are equally distributed portside and starboard side. The fpwo “fast-track” approach of the Girassol development required the FPSO execution to face the following challenges: Support and safety systems are designed for people including visitors.

Contact a Yokogawa Expert to learn how we can help you solve your challenges. Co-ordination, team spirit and parallel engineering were the keys to successful completion of the assignment.

Further developments are being assessed, and would consist of additional risers and associated utilities on the FPSO. Sailaway of the FPSO from the construction yard in South Korea occurred at the end of March at a level of completion and commissioning never achieved before for a production unit of such complexity.

The key dates for the project were: Yokogawa is in charge of the maintenance contract for the Integrated Control and Safety system which includes assistance on site for all components: Introduction Discovered in Aprilthe Girassol field development was sanctioned two years later in July based on a subsea production scenario associated with a large FPSO, having the following main characteristics: Proceedings of an International Conference Submersible Technology: Rock Mechanics Symposium and 5th U.


Proceedings of an international conference Oceanology: These tools also helped during pre-commissioning at the yard, towing some of our engineers had a free cruise on board the FPSO to finalise some modifications! From the first months after discovery, the Girassol FPSO development history described here presents how the Operatorand its Contractors, through the contracting strategy, the main architectural choices and project execution, faced these challenges and managed the successful FPSO development, crowned by first oil 41 months after project sanction.

Cofferdams are installed between methanol and cargo tanks, and between machinery space and cargo tanks.

Since the technology used in fpsso process is new, and as wells start production one by one, the tools have to be very flexible so that modifications can be carried out online and single modifications downloaded without stopping production. The FPSO is equipped with: Accommodation and life saving. Cathodic protection of the hull is performed by sacrificial anodes in the tanks. Another key success factor was that Yokogawa shipped equipment to certain package vendors in order ffpso validate the interface up as far as the man-machine operator interface.

The methodology for keeping track of modifications is of course closely monitored. The main difficulty of the project lay in the fact that only pre-basic engineering studies had been completed when the DCS was awarded, meaning that the engineers working on the f;so had to perform several tasks in parallel during detailed engineering. The living quarters provide accommodation for persons into eight executive cabins, twelve single bed cabins.

The general layout of the topsides is governed by safety considerations with the most hazardous equipment being. Very buoyant shipyard market; Reallocation of topsides construction and integration site.

The control and monitoring include not only the topsides modules but also the subsea equipment and the vessel packages. The Operator, in developing the FPSO, employed parallel engineering, functional specifications and an early involvement of the industry with an original contracting strategy in order to achieve the Girassol field development in less than six years from discovery to first oil setting a rpso standard for the Industry.

Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Proceedings of an international conference Subsea Controls and Data Acquisition ‘ Once this phase had been completed and validated by all the partners, the application configuration was performed using user friendly tools which secured the application and facilitated the tests.

Yokogawa was able to achieve this using its standard tools.
