at that time, was appointed as CEO, and also as chairman of Total in 2015. In 2015, Total unveiled plans to cut 180 jobs in the United Kingdom, reduce refinery capacity and slow spending on North Sea fields after it fell to a $5.7bn final-quarter loss. The company said it would also sell off $5bn worth of assets worldwide and cut exploration costs by 30%. In 2016, Total signed a $224M deal to buy Lampiris, the third-largest Belgian supplier of gas and renewable energy to expand its gas and power distribution activities. In 2016, Total agreed to buy French battery maker Saft Groupe S.A. in a $1.1bn deal, to boost its development in renewable energy and electricity businesses. In 2016, Total agreed to acquire $2.2-billion in upstream and downstream assets from Petrobras as part of the firms' strategic alliance announced earlier that year. For Total, these new partnerships with Petrobras reinforce Total's position in Brazil through access to new fields in the Santos Basin while entering the gas value chain. Between 2013 and 2017, Total organized the ARGOS Challenge, a robotic competition with the aim to develop robots for their oil and gas production sites. It was won by an Austrian-German team using a variant of the taurob tracker robot. In 2017, Total signed a deal for a total amount of $4.8b with Iran for the development and production of South Pars, the world's largest gas field. The deal was the first foreign investment in Iran since in the 2015 sanctions over Iran's nuclear weaponisation were lifted by the JCPOA. In 2017, Total announced the acquisition of Maersk Oil for $7.45 billion in a share and debt transaction. This deal positioned Total as the second operator in the North Sea. In 2017, Total signed an agreement with EREN Renewable energy to acquire an interest of 23% in EREN RE for an amount of €237.5 million. In November 2017, Total announced the launch on the French residential market of Total Spring, a natural gas and green power offering that is 10% cheaper than regulated tariffs. Total is thus pursuing its strategy of downstream integration in the gas and power value chain in Europe. In 2018, Total officially withdrew from the Iranian South Pars gas field because of sanctions pressure from the US. In 2019, Total announced sale of 30% stake in the Trapil pipeline network to crude oil storage operator Pisto
