INTEGRATED TUG-BARGE UNITS FOR OCEAN TRANSPORTATION OF LNG

A summary of the history of ocean tug-barge units is presented and includes the development stages of tug-barge linkage concepts which evolved as a result of towing and maneuvering problems. A brief discussion of LNG tug-barge design and economics considers such aspects as vessel production, model tests, stern dock, LNG tank requirements, and repair and maintenance requirements. Based on this survey, the author concludes that integrated tug-barge units are expected to be the least-cost method of transporting LNG under the U.S. flag.
