Eni enlists GTT’s tank maintenance skills for FLNG gig

Italy’s oil and gas giant Eni has handed out a contract to France’s technological containment specialist Gaztransport & Technigaz (GTT) for servicing its floating liquefied natural gas (FLNG) unit offshore Mozambique.

The scope of the agreement entails technical support services to ensure the efficient operation and maintenance of the liquefied natural gas (LNG) storage tanks on board the Eni-operated Coral Sul FLNG. The French player will provide on-site and remote technical assistance, on-site testing, inspection, emergency assistance, engineering services, and specialized training programs.

GTT’s Chief Executive Officer (CEO), Jean-Baptiste Choimet, said: “We are proud to accompany Eni on the Coral Sul FLNG project, which contributes to the development of the LNG industry in Africa. GTT remains committed to providing tailor-made, innovative services that support the transition to cleaner energies.”

GTT’s Mark III membrane containment system was selected for the FLNG’s eight LNG tanks in 2017 when the unit was said to be the second biggest in the world. Boasting a production capacity of 3.4 million tonnes of LNG per year and a storage capacity of 238,700 cubic meters, the barge is situated in the Coral reservoir within the Rovuma supergiant gas basin offshore Mozambique.

Mozambique Rovuma Venture (MRV) – comprising Eni, ExxonMobil, and China National Petroleum Corporation (CNPC) – holds a 70% interest in the Coral Sul FLNG project, with the remaining 30% split equally between Empresa Nacional de Hidrocarbonetos (ENH), Kogas, and as of recently ADNOC, after it inked a deal to purchase Galp’s 10% interest.

The FLNG has been producing and exporting LNG and condensate since October 2022, with the first shipment following suit one month later. Its current production levels of around 24,000 cbm of LNG per day are said to exceed expectations, enabling the delivery of one weekly LNG shipment and one bi-monthly condensate shipment, or 75 LNG shipments and 11 condensate shipments since starting operations.
