Twin City Shipyard Signs Licensing Agreement With Flohr To Build And Sell Portabarges Twin City Shipyard, Inc., a subsidiary of Twin City Barge & Towing Company, St. Paul, Minn., announced it has concluded an ex- clusive licensing agreement with Flohr & Com- pany Metal Fabricators, Inc., Seattle, Wash., to manufacture and sell the firm's patented "Portabarges" in the states of Alaska, Wash- ington, Oregon, Idaho and California. John Buursema, executive vice president of Twin City Shipyard, explained that Porta- barges are 40 by 10^-foot barges equipped with interlocking devices that enable them to be trucked into remote sites and then joined together to form a huge construction barge of almost any conceivable configuration. Mr. Buursema said that Flohr is a major West Coast steel fabricator serving the marine and fishing industries. "Flohr's acceptance of the Portabarge provides further testimony to the need and desirability of this novel marine construction device," he commented. Mr. Buursema said that Twin City Shipyard has sold or leased some 50 Portabarge units since they were introduced about a year ago. Twin City Barge & Towing Company, the parent company of Twin City Shipyard, is a publicly owrred firm which has served the Twin Cities area since 1937, and Chicago since 1961. The company operates towing and barge-fleet- ing services around these cities, tank-barge service at St. Paul and Chicago, and the only shipyard and large boat store in the St. Paul area. Small Tanker Contract Awarded To Barbour Boat Barbour Boat Works, Inc., New Bern, N.C., announced that it has recently signed a con- tract for construction of a 1,600-dwt tanker for service in South America and Central Amer- ica. The twin-screw vessel will be 230 feet in length overall, with a 39-foot beam and a de- sign speed of 12 knots at 1,700 horsepower. The vessel will be built under American Bu- reau of Shipping Classification and will be de- signed for unmanned engine room operation. Design and engineering will be accomplish- ed by James S. Krogen and Co., Inc. of Miami, Fla., in conjunction with Barbour Boat Works, Inc., in house engineering. This vessel is the second for Coral Petro- leum Co., Ltd., an affiliate of Jersey Standard. The 155-foot Esso Islander was delivered by Barbour Boat Works, Inc. in the spring of 1970. ZIDELL BARGE DELIVERY: Two steel barges, each 124- feet long, were delivered by Zidell Explorations, Inc., Port- land, Ore., to the Puget Sound Naval Shipyard at Bremer- ton, Wash., during the last week of 1970. The delivery brought to eight the number of barges built for the Navy since 1969 by Zidell's Marine Construction Division. Total price of the barges was approximately $2.7 million. During the peak of construction on the Navy barges, Zidell employed about 250 men. In addition to the Navy barges, Zidell delivered nine barges, ranging in length from 135 feet to 222 feet, to Pacific Northwest com- mercial customers. The latest, a 222-foot grain barge, was launched December 30 for Tidewater Barge Lines. J. L. BLUDWORTH NAVAL ARCHITECT!
