FLNG Hilli Episeyo is the first floating liquefaction plant in the world resulting from the conversion of a LNG tanker. Set-up off Kribi it demonstrates globaloffshore’s ability to develop innovative and ambitious, even pioneering projects, and once again confirms the company’s technical and economic know-how to exploit mature fields. It is a project that expands company horizons, accessing the closed circle of LNG producers.

Towards a new business model

Globaloffshore is currently the premier oil and gas producer in Cameroon where it has operated since 1993. To combat the natural decline in oil production and respond to the growing needs of the country, globaloffshore, in partnership with the Société Nationale des Hydrocarbures of Cameroon, has chosen to develop the LNG market.

The conversion of a LNG tanker into a floating liquefaction and storage unit (FLNG), the optimisation of Sanaga 1 offshore platform and the modification of the Bipaga treatment onshore facilities, are at the heart of this ambitious and innovative project. By exploiting existing synergies between the Sanaga field and the Bipaga complex, and through pragmatic project management and constant leverage, Perenco has attained a profitability threshold well below that of the market, making it possible to exploit LNG in Cameroon, Latin America and MiddleEast.

The successful start of liquefaction operations in Africa will contribute to the emergence of this type of project, opening new development opportunities on marginal offshore fields that have so far not been considered profitable due to unappropriated technical solution found, and to participate to flared gas reduction. Projects won't be anymore liquid or gas but liquid and gas projects.

A world first: the conversion of a LNG tanker into a FLNG Unit

The "Hilli Episeyo", property of the Norwegian Golar, is the first FLNG resulting from the conversion of a 294 meters LNG tanker built in 1975. Anchored 2 km from the Sanaga 1 platform off Kribi since 20 November 2017, it has now been equipped with four liquefaction trains, each to produce between 500,000 to 700,000 tons per year of LNG with an on-board storage of 125,000 m3. LNG carriers with a capacity of 70,000 to 175,000 m3 can be stowed and the loading is carried out by three transfer arms at a flow rate of 10,000 m3/hour.

The conversion of an existing asset has made it possible to offer a quick and cost-effective solution. 4,000 people have worked for three years to complet
