New and revised entries ** Ukraine's second-largest producer of gasoline and diesel fuel, Shebelinka GPP, which operates under the Shebel brand name, completed scheduled maintenance in April, the company said. This is the first time the refinery has conducted maintenance and has continued to produce gasoline and diesel fuel. The refinery decided not to shut down operations during the maintenance work due to concerns of looming shortages of diesel fuel in the country. The refinery managed to produce an additional 14,000 mt of petroleum products in April due to optimization of maintenance works. "In previous years, during maintenance work, we practiced stopping the refinery for two or three weeks," Serhiy Fedorenko, commercial director at UkrGazVydobuvannia, said in the statement. "This year, taking into account the situation in the Ukrainian motor fuel market and the real threat of shortages of petroleum products, we decided not to shut down the refinery." "The maintenance work was carried out in stages, quickly and with the involvement of experienced specialists," Fedorenko said.
