NABRICO Delivers 260-Foot RO/RO Barges For Boston Harbor Project

Nashville Bridge Company (NABRICO), a subsidiary of the American Ship Building Company, recently delivered two 260-foot specially configured Roll-On/Roll-Off (RO/ RO) barges to Allied Maritime Management organization, a subsidiary of Seaworthy Systems, Inc., at its Nashville, Tenn., yard, for use in the Boston Harbor Clean-Up Proj- 6 C t .

NABRICO president Allen Zang said that despite unfavorable weather conditions during the final stages of construction, the barges were delivered on time and within budget. Allied's chairman, David O'Neil and its president, Ralph A.

Corvino, accepted the barges and extended their thanks to NABRICO for its near-record delivery.

The barges, each with a beam of 64 feet and draft of 12 feet, were christened the Seaworthy I and Seaworthy II. Mrs. Joanne O'Neil, wife of Mr. O'Neil, sponsored the Seaworthy I, while Mrs. Patricia McCarthy, wife of Seaworthy vice president, William McCarthy, sponsored the Seaworthy II. Jon Wales, vice president of Boston Towing & Transportation, which will operate the RO/RO system, was on hand to take delivery of the barges from Allied.

The two 25 tractor-trailer-capacity barges will be utilized to transport construction-related vehicles across Boston Harbor. The vessels will be loaded at the project's staging area at the former Fore River Shipyard in Quincy, Mass., on a reg ular "ferry-like" schedule. The unloading point will be at the major construction site in the extreme northeastern corner of the harbor at Deer Island. At the site, new primary and secondary sewage treatment facilities will be constructed along with an effluent outfall tunnel extending nine miles under the ocean floor in Massachusetts Bay.

The vessels are designed to permit the rapid securing of trailers to mate with purpose-built shoreside transfer bridges and incorporate many other safety and environmen- tal features.

The 10-year project is under control of the Massachusetts Water Resources Authority and is being directed by the contract's program/ construction managers, Kaiser Engineers, Inc. Seaworthy Systems, Inc., Essex, Conn., provided consulting engineering to RO/RO system operator Boston Towing & Transportation.
