Overseas Shipholding Group, Inc. announced that it has exercised an option to construct a second 204,000 barrel Oil and Chemical ATB Barge at Gunderson Marine LLC’s Portland, Oregon facility. The barge, scheduled for delivery in the second half of 2020, will be designed and built to be paired with one of the company’s existing modern tugs, replacing a rebuilt barge unit which is expected to be phased out of service prior to delivery of the new barge. Each of the two barges contracted with GM will be of identical design, meeting all of the latest safety and environmental requirements. The company intends to finance the construction of the two barges at GM with a combination of existing cash and future debt financing.
