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.

Further developments are being assessed, and would consist of additional risers and associated utilities on the FPSO.

Yokogawa is very pleased to have been able to take part in this major project, which requires not only long-term support and integration but also co-ordination and close partnership with the key players. The methodology for keeping track of modifications is of course closely monitored. Topsides General lay out The general layout of the topsides is governed by safety considerations with the most hazardous equipment being arranged away from the accommodation area Figures A-2 and A 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.

Accommodation and life saving The living quarters provide accommodation for persons into eight executive cabins, twelve single bed cabins, sixty double bed cabins. 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: Cathodic protection of the hull is performed by sacrificial anodes in the tanks.

The ability to perform modifications on-line is an essential factor in ensuring uninterrupted production. Cofferdams are installed between methanol and cargo tanks, and between machinery space and cargo tanks. Yokogawa is in charge of the maintenance contract for the Integrated Control and Safety system which includes assistance on site for all components: Proceedings of an International Conference Foso Technology: Co-ordination, team spirit and parallel engineering were the keys to ggirassol completion of the assignment.


The key dates for the project were: Abstract While the history of floating production storage and offloading FPSO is paved with record cost overruns and delays, through the description of the Girassol FPSO project, this paper presents the ways and means used by the Operator- TotalFinaElf – to manage the successful development of the world’s largest deepwater FPSO installed in the Girassol field, offshore Angola.

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. Rock Mechanics Symposium and 5th U.

About us Contact us Help Terms of use. 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!

The hull construction subcontract was performed in 19 months and the construction of the 25,tonnes topsides subcontract was done in 21 girasxol. 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 project had to perform several tasks in parallel during detailed engineering.

Proceedings of an international conference Diverless and Deepwater Techology: Peer reviewed only Published between: The FPSO described here is now the only visible facility of this pioneering project for the offshore industry Figure A Name of the ship. The FPSO is equipped with: All ballast tanks are painted and the hull exterior is protected by impressed current.

Girassoo and life saving. The first phase of the project involved defining the guidelines which would provide the basis for the application configuration while the detailed engineering was in progress.

The control and monitoring include not only the topsides modules but also the subsea equipment and the vessel packages. Since the technology used in the 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 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 new standard for the Industry. Parallel pfso engineering and surface facilities development; Interface data issues due to different schedule in design development between UFL and FPSO; Management of significant design data changes in throughput and treatment giraesol during contract execution; Additional challenges to the FPSO development came from the following adverse events which occured during the course of the project execution: Yokogawa was able to achieve this using its standard tools.

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. Yokogawa is currently 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.

Contact a Yokogawa Expert to learn how we can help you solve your challenges. The completion, just 33 months after the award of a contract based on functional specifications, constituted a new benchmark for future FPSO’s. The living quarters provide accommodation for persons into eight executive cabins, twelve single bed cabins.

Main tanks are equally distributed portside and starboard side. Advanced search Show search help. Very buoyant shipyard market; Reallocation of topsides construction and integration site. Offshore Technology Conference Disciplines 4.

Another key success factor was that Yokogawa shipped equipment to certain package vendors in order to validate the interface up as far as the man-machine operator interface.

The initial “fast-track” approach of the Girassol development required the FPSO execution to face the following challenges:
