Jamaica's refining company Petrojam has launched tenders to buy two 140,000-205,000 barrel cargoes combining gasoline, jet fuel and high-sulfur diesel and a 150,000 barrel cargo of fuel oil, all of them to be received on August 20-29 at Kingston, according to documents seen by Reuters on Monday. Petrojam produces most of fuels demanded by Jamaica's domestic market at its 35,000 barrel per day Kingston refinery shared with Venezuela's state-run PDVSA, but it also buys finished products and feedstock on the open market. The first cargo should arrive on August 20-22 containing 50,000 barrels of 84-octane gasoline, 50,000 barrels of 88-octane gasoline and 40,000 barrels of jet fuel.
