I n December 2018, Kosmos and BP completed a 34-month effort to write and obtain approval of the Greater Tortue Ahmeyim (GTA) Environmental and Social Impact Assessment (ESIA) and associated Environmental Management Plan. There were numerous public consultations and inquiries conducted in both Mauritania and Senegal (more than 3,000 people participated) and it is believed to be the first time that both countries, with different regulatory requirements, approved a single study of a private-sector project. Following approval of the ESIA, Kosmos and BP announced a final investment decision (FID) for Phase 1 of the GTA project. The GTA project will produce gas from a deepwater subsea system and mid-water FPSO to a floating liquefied natural gas (FLNG) facility at a nearshore hub located on the Mauritania and Senegal maritime border. The FLNG facility for Phase 1 is designed to provide approximately 2.5 million tons per annum on average. Production is expected to begin in the first half of 2022. Subsequent phases, which are now being planned, are expected to increase output to around 10 MTPA. Kosmos and BP estimate that there is 50-100 trillion cubic feet (Tcf) of gas in place offshore Mauritania and Senegal, enough to eventually support three 10 MTPA LNG hubs – at Tortue on the maritime border, at Bir Allah to the north in Mauritania, and at Yakaar-Teranga to the south in Senegal. MANAGING OUR FOOTPRINT Kosmos has been supporting BP in its role as operator in managing the footprint of all activities in Mauritania. Most notably, this includes preparations for entering the construction phase of the GTA project. As part of the transfer of operatorship, most Kosmos employees transitioned to BP at the end of 2017. Since then, we have hired a new Mauritanian country manager and support staff to maintain our employment of 100% Mauritanian nationals in our Nouakchott office. ENGAGEMENT AND LISTENING Our gas discoveries offshore Mauritania mean that we expect to have a presence in the country for many years to come. We want to be a welcome investor, both to our host governments and local communities. To achieve this goal, we build relationships with stakeholders through engagement and listening on all topics: the environment, transparency, our operations, capacity building and social investment projects, health and safety, and socioeconomic impacts. We are pleased to support the government of Mauritania’s commitments to transparency. The Mauritanian Hydrocarbon Code of 2011 requires companies to publicly disclose the payments they make to government. In 2017, Kosmos served as a private sector member of Mauritania’s EITI National Committee. Since discovering large deposits of natural gas offshore Mauritania in 2015, Kosmos has pursued a development strategy for this resource aimed at bringing benefits to the country as quickly and efficiently as possible. The benefits are expected to include revenue from the export of liquefied natural gas (LNG), the economic impact of reliable power generated from a plentiful and low-cost source of energy, and the significant follow-on benefits of industrial development. 43 The first phase of the Greater Tortue Ahmeyim gas project is expected to take just seven years from discovery to first production, an industry-leading timeline.
