Sulzer and FMC Technologies have received a subsea multiphase boosting pump contract to upgrade one of the pumping modules in Shell’s Parque das Conchas, a deepwater oil field off the coast of Brazil. The pump modifications suit the specifics of the oil field with a high shut-in pressure of 517bar (7,500psi). They meet Shell’s maintenance and service needs with high reliability and short turnaround intervention.
The Parque das Conchas, also known as the Shell BC-10 field, is situated in deep water, approximately 120km (75 miles) south-east of the Brazilian coastal city of Vitória. The BC-10 asset has water depths ranging from 1,500m to 2,000m. It is operated by Shell, with a 50% working interest. ONGC Videsh and Qatar Petroleum International are joint venture partners with 27% and 23%, respectively.
A key part of the success of the project has been the collaboration between Shell, FMC Technologies, and Sulzer. The subsea pump will be manufactured from a global supply chain with a large amount of assembly and testing conducted at Sulzer’s facilities in the UK.
The advantage of the mudline pump is that it fits into an existing infrastructure with minor and cost-efficient modifications, yet is smaller and lighter than the pump it replaces. Smaller does not mean less performance: The pump achieves the necessary oil volume and boosting outputs.
This first subsea pump for Shell from FMC Technologies and Sulzer will be launched in the field in 2017. It will demonstrate the pump’s capability to maintain yield levels and achieve excellent reliability targets in the harsh deep-sea environments.
