Tampa, Fla. - 17 July 2018

Overseas Shipholding Group, Inc. (NYSE: OSG) (the “Company” or “OSG”) a provider of energy transportation services for crude oil and petroleum products in the U.S. Flag markets, announced today that it has signed binding contracts with Hyundai Mipo Dockyard Company Ltd. (“HMD”) for the construction of two 50,000 deadweight tons class product chemical tankers for anticipated delivery to the Company during the second half of 2019. These tankers will be constructed at HMD’s Ulsan, Korea ship building facilities and will be built to comply with MARPOL Annex VI Regulation 13 Tier III standards regarding nitrogen oxide emissions within Emission Control Areas.
