... step forward. After producing for 12 years, it became China’s first abandoned offshore field. Recently, the field had its first oil for the second time, when the owner re-developed the same field using a different concept with a 19-km subsea tieback and new subsea boosting technology. In combination...

... Consider the following statistics: Abstract Subsea tiebacks are a principal building block of deepwater developments. Operators seek to continuously enhance operational efficiencies and tieback distances while reducing capital, operating expenditures, and emissions. Rapid advances have been...

..., necessitating innovative solutions. Moreover, the paper will discuss the solutions that have been applied and the results obtained in the Campos Basin's renewal strategy. It includes the development of subsea tiebacks into existing facilities and planned subsea tiebacks into production hubs. These initiatives...

... Abstract Subsea tiebacks of oil discoveries to existing host platforms are currently, and will continue to be, the most sanctioned deepwater projects because they are fast paced and profitable. Deepwater liquid subsea tieback distances today are technically constrained to about 35 km. Globally...

... as e.g. Electrical Heat-Traced (EHT) pipe-in-pipes. The aim of this paper is to present a comparative study that has been made on the cost, delivery schedules, and local content of various heated pipelines technologies for subsea tiebacks, with specific application targets, notably in West Africa...

... or in synergies, depend on the specific projects and can be identified in a timely manner thanks to early engagement of Contractor in the architecture and associated pricing of subsea tiebacks. The paper will present a platform of technologies, their maturity status and how they can be integrated in novel...

... Abstract Offshore developments must evolve if the industry is to unlock subsea reserves and increase recovery. A novel method of achieving these goals is through use of a systematic approach to subsea tiebacks that combines new technologies with minor modifications to the existing topsides...

... Abstract Gas hydrates forming in deep water subsea tiebacks can stop production of offshore wells by blocking the pipeline. This is considered one of the most challenging problems in flow assurance. In this work, we present a transient hydrate simulation tool with the ability of predicting...

... Abstract The paper describes conditions involving the plugged flowline of a >20 mile subsea tieback in the Gulf of Mexico and the innovative techniques and procedures that were utilized in the remediation process. The procedures performed also provided information used for locating...

..., long-distance subsea tiebacks are becoming a preferred field development option. At high pressures and low ambient temperatures, the multiphase fluid is in the hydrate region close to the wellhead requiring continuous injection of thermodynamic inhibitors. Severe operating conditions require high...

... to the top of the list for many will be subsea tieback solutions. Some will be associated with existing host facilities, some with new floating facilities, and some, like Corrib and Ormen Lange, will even be considered for direct subsea tie-back to shore-based facilities. This mix of fast-track subsea...

... Abstract The field under evaluation is situated approximately 50 miles from shore inwater depths ranging from 1,300 ft to 2,300 ft. Since the field is nearer to shore than at least one other long subsea tieback the operator felt that itmight be possible to develop it using only subsea...
