Studies of the performance of concrete barges of Worlds War II vintage indicated that they showed no signs of hull deterioration after almost two decades of service. Howver, in spite of the manifold adavantages these barges have, their weight which effects operating and carrying conditions, created severe disadvantages over steel barges. Prestressed concrete barges, on the other hand, have been developed with all of the salient advantages of both concrete and steel barges. This paper describes the design and construction of nineteen 2000 ton (1.8 x 10^6 kg) DWT and 85 ton (7.7 x 10^5 kg) DWT prestressed concrete barges for interisland and ocena-going service. Of special interest are finding on the performance of these barges after 8 years service in the Pacific and Southeast Asia areas.
