MAN compression technology for Senegal’s first offshore development project

MAN Energy Solutions has received an order for a total of six compressor trains to be used on the Sangomar FPSO off the coast of Senegal.
Back to previous page

MODEC has placed an order for six compressor trains for an FPSO (floating production storage and offloading) unit, which will be deployed on the Sangomar field approximately 100 km south of Dakar, Senegal. Together with the nearby Rufisque and Sangomar Offshore blocks, it is one of the world’s largest oil & gas discoveries of the last decade.

"We are delighted and proud to have been selected to provide the memorable first FPSO for Senegalese waters," commented Yuji Kozai, President and CEO of MODEC. "We consider West Africa where numerous offshore oil and gas fields have been discovered in recent years, as one of our most important core regions, and this contract award should geographically reinforce our business portfolio. We are equally pleased to be a part of the team that will provide a needed energy resource for the people of the Republic of Senegal. We look forward to cooperating closely with our clients and partners to make this project a success."

“Senegal has a bright energy future ahead and we are proud that MAN Energy Solutions will take an active part by providing high-end technology solutions for the Sangomar field,” states Patrik Meli, Senior Vice President, Managing Director of MAN Energy Solutions Switzerland Ltd. “Gas is becoming economically and environmentally the world’s most significant energy source for the next couple of decades. This important order is a further testimonial of the trust put in our well-founded technology knowhow in the energy sector.”

The total order comprises six centrifugal compressor trains: one low pressure (LP), three medium pressure (MP) and two high pressure (HP), which are all driven by fixed speed electric motors. All compression systems will be designed, manufactured and tested by MAN Energy Solutions in Zurich (Switzerland). The machines will be ready for installation in the fourth quarter of 2021.

Once they are in operation, the compression systems will help maintaining the pressure of the Sangomar field, thus maximizing the quantity and efficiency of hydrocarbon production. The FPSO will be capable of processing 100,000 barrels of oil and 130 million standard cubic feet of gas per day. First production is planned for 2023.

Basil Zweifel, Vice President Sales and Execution Upstream and Midstream at MAN Energy Solutions, adds as follows: "We are honoured to have the opportunity to work with MODEC on this project within the emerging energy market of Senegal. MAN Energy Solutions provides energy-efficient, highly reliable and cost-effective compression solutions. These are crucial requirements for new generation projects like Sangomar.”

Woodside completes landmark FPSO for Senegal
Sangomar floater heads to Singapore for topsides integration and commissioning work

Image

[UpstreamOnline] Woodside Energy has completed construction of the floating production, storage and offloading vessel destined for its Sangomar oilfield development offshore Senegal and has acknowledged its Chinese sub-contractors for their fabrication and conversion works.

The Leopold Sedar Senghor FPSO, named after Senegal’s first president, is now en route from China to Keppel Offshore & Marine’s Tuas yard in Singapore for completion of topsides integration and where pre-commissioning and commissioning activities will be performed.

First oil is on track for late 2023.

The FPSO, a converted very large crude oil carrier, will have the capacity to produce 100,000 barrels per day of crude.

The Sangomar Phase 1 project is currently around 70% complete and will be Senegal’s first offshore oil project. The development includes the FPSO, 23 wells and supporting subsea infrastructure, designed to allow the tie-in of subsequent phases.

Australian operator Woodside in 2020 awarded Modec of Japan the contract for the floater for its Sangomar Phase 1 development.

Hull and marine works, external turret and topsides module installation and conversion work on the FPSO were completed by China’s Cosco Shipping Heavy Industries (Cosco). The topsides modules were built by Cosco and compatriot Bomesc Engineering Company (Bomesc) while China’s Penglai Jutal Offshore Engineering (PJOE) built the external turret mooring system.

Woodside chief Meg O’Neill acknowledged the achievements of Modec, Cosco, Bomesc and PJOE in completing the fabrication and conversion works.

“The Chinese yards achieved excellent safety performance throughout this phase of construction, logging more than 16 million hours of complex construction work without a lost-time injury event.

“The construction teams also successfully navigated the challenges posed by pandemic-related travel and logistical restrictions throughout 2021 and 2022, ensuring the FPSO remained on schedule for start-up at the Sangomar field in late 2023,” she said on Tuesday.

However, Upstream reported on 11 November that the floater was being moved from China to Singapore for the topsides integration work, apparently due to concerns over China’s coronavirus lockdown measures and how they might have an impact on the completion of the project.

The Leopold Sedar Senghor FPSO is now expected to be delivered from Keppel O&M in the first quarter of next year.

Woodside has an 82% operated participating interest in the Sangomar project with Petrosen holding the remaining 18%.
