LNG

UK major BP said the floating production storage and offloading (FPSO) vessel, a key component of the floating LNG development on the maritime border of Senegal and Mauritania in West Africa, has arrived at its final location.

Golar LNG Ltd, the shipping company with a small but growing fleet of floating liquefied natural gas production and project vessels including the “Hilli Episeyo” offshore Cameroon and the “FLNG Gimi” for offshore Mauritania and Senegal, swung to a profit from a previous loss.

Seatrium of Singapore, a leader in LNG project and ship conversions as well as platforms for conventional oil and gas ventures, was awarded a contract by Shell Offshore to construct and integrate the hull, topsides and living quarters of the Sparta semi-submersible floating production unit (FPU) to be deployed in the US Gulf of Mexico.

Seatrium’s Shell contract includes the installation of Shell-furnished equipment and follows a letter of intent signed by both parties in August 2023.

The Sparta FPU will be situated in the Garden Banks area of the US Gulf of Mexico, about 275 kilometres (171 miles) off the coast of Louisiana.

Seatrium said the platform would feature a single topside bolstered by a four-column, semi-submersible floating hull and would be designed to produce 90,000 barrels of oil equivalent per day.

LNG record

Seatrium, formerly called Sembcorp Marine Ltd and renamed as Seatrium following its merger with Keppel Offshore & Marine, had previously in November 2023 successfully delivered the Greek “FSRU Alexandroupolis” to be deployed offshore northeast Greece as part of a Balkans LNG supply hub.

The Singaporean company also in November handed over the LNG production unit for the BP-led FLNG project offshore Senegal and Mauritanian in West Africa and also involving Dallas-based Kosmos Energy.

Analysts note that the combined Seatrium group is becoming better known in marketing terms as a single unit and provider of engineering solutions to the marine, offshore and energy sectors, particularly in assembling topsides safely and efficiently at ground level.

Seatrium said that the two-level topside for Sparta would be integrated and lifted to the hull using Seatrium’s Goliath twin cranes capable of lifting up to 30,000 tonnes.

“We are deeply honoured that Shell has awarded Sparta, the third FPU newbuild, to Seatrium, following the successful deliveries of the Vito and Whale FPUs,” said
William Gu, Executive Vice President and Head of Oil & Gas International at Seatrium.

Affirmation

“It is a strong affirmation of our team’s capabilities and the long-standing partnership between both parties. We are fully committed to executing the project well, including the single lift operation and fabrication of the FPU to meet its 20,000-psi design for use in harsh weather conditions, and delivering the unit to Shell safely and efficiently,” Gu explained.

Seatrium added that the Sparta FPU was conceived as a replicable project between Shell and Seatrium to leverage the group’s topsides single lift integration methodology, following the Vito and Whale newbuilds.

“With an extensive experience in complex offshore projects, Seatrium is well-positioned and equipped with cutting-edge technology to deliver high-quality engineering, procurement, installation and commissioning (EPIC) services for fixed and floating production platforms and subsea developments,” the company stated.

The Republic of the Congo and Italian energy major and liquefied natural gas projectdeveloper Eni have witnessed the sail away from Dubai in the United Arab Emirates of two vessels that will comprise the African nation’s first floating LNG production venture.

The two vessels left Dubai at a ceremony attended by Bruno Jean Richard Itoua, Minister of Hydrocarbons of the Republic of the Congo, Maixent Raoul Ominga, Managing Director of state energy company Societe National des Petroles du Congo (SNPC) and Guido Brusco, Chief Operating Officer for Natural Resources for FLNG developer Eni.

Eni said that the “Tango” FLNG vessel that formerly operated in Argentina is now on its way to the West Coast of Africa along with the “Excalibur” floating storage unit (FSU).

“The milestone aligns with the timeline of the Congo LNG project, whose first phase will start-up in December 2023,” said Eni.

FLNG surge

When Congo FLNG starts it will be the third project operating in Africa after Cameroon FLNG, Mozambique FLNG and with other ventures being developed in nations like Nigeria.

Two more FLNG facilities are being developed in joint projects for Senegal and Mauritania in West Africa and involving UK major BP and Dallas, Texas-based Kosmos Energy.

The “Tango” FLNG production hull has a liquefaction capacity of around 1 billion cubic metres per annum of gas.

It will be moored about three kilometres offshore along with the “Excalibur” FSU upon their arrival in Congo territorial waters.

“The Congo LNG project leverages Marine XII natural gas resources and existing production facilities in a new, phased approach that will be allowed to reach approximately 4.5 Bcm a year of gas liquefaction capacity at plateau, as well as zero routine gas flaring,” Eni explained.

The Milan-based company added that a second FLNG vessel with a capacity of about 3.5 Bcm of gas is under construction and will be deployed in 2025.

“The project will help the Republic of the Congo meet its energy needs while seizing the opportunity to exploit surplus gas through LNG production, allowing the country to join the group of global exporters of LNG in record time,” stated Eni.

“According to the agreements recently signed, all LNG produced will be marketed by Eni,” the company added. 

The Republic of the Congo has formally launched two floating liquefied natural gas production projects that may make the West African nation an LNG exporter by as early as this year as African nations assume leadership of the FLNG sector to monetize their resources backed by Western oil majors.

Kosmos Energy, the US shareholder in the floating liquefied natural gas joint venture offshore the West African nations of Mauritania and Senegal, halved its losses in the first quarter and said material progress was made across all the major workstreams of the LNG project centred on the Greater Tortue-Ahmeyim gas fields.
