Type II. Cargo will be heated with hot oil circulating through four sets of coils in each cargo tank, coiled and arranged that the loss of one set of coils will not detract from the overall heating ability of the system. Hot oil will heat the cargo pumps, fill lines, vents and drip pan drains, while above deck cargo piping and the drip pans will be heated with steam supplied from external sources. A heat exchanger will transfer heat from the shore-supplied steam to hot oil. The cargo heating system, which was designed by Shearer and PCS, provides a quality heating system with due con- sideration for the type of cargo and the

All six barges will be fitted with 40- ton manual winches and will have iden- tical semi-integrated hull configurations from the main deck down — all will have coatings specially designed for operation in salt water. External hull scantlings based on two PCS barges constructed in 1992 will be present on the six vessels as well. All external and internal welding will be double continu- ous to strengthen the structural integrity of the hull scantlings and to provide bet- ter coating surfaces.
