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.

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.

Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Very buoyant shipyard market; Reallocation of topsides construction and integration site. Peer reviewed only Published between: Proceedings of an international conference Subsea Controls and Data Acquisition ‘ 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.
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.
Girassol FPSO – A Barrel Full
Co-ordination, team spirit and parallel engineering were the keys to successful completion of the assignment. All ballast tanks are painted and the girassol exterior fpsl protected by impressed current. The initial “fast-track” approach of the Girassol development required the FPSO execution to face the following challenges: The control and monitoring include not only the topsides modules but also the subsea equipment girassll the vessel packages.
The hull construction subcontract was performed in 19 months and the construction of the 25,tonnes topsides subcontract was done in 21 months. 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.
The key dates for the project were: Main tanks are equally distributed portside and starboard side. 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 The girassoo for keeping track of modifications is of course closely monitored.

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. Proceedings of an International Conference Submersible Technology: 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 FPSO described here is now the only visible facility of this pioneering project for the offshore industry Figure A The completion, just 33 months after the award of a contract based on functional flso, constituted a new benchmark for future FPSO’s.
Abstract While the history of floating production storage and offloading FPSO is paved fpdo 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.
The ability to perform modifications on-line is an essential factor in ensuring uninterrupted 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.
The general layout of the topsides is governed by safety considerations with the most hazardous equipment being. Log in to your subscription Username. Contact a Yokogawa Expert to learn how we can help you solve your challenges.
The FPSO is equipped with: Yokogawa was able to achieve this using its standard tools. 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: 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.
Cathodic protection of the hull is performed by sacrificial anodes in the tanks. Parallel reservoir 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 capacity during contract execution; Additional challenges to the FPSO development came from the following adverse events which occured during the course of the project execution: 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.
