On the river barge of 3000 T preliminary seakeeping approach

Abstract

This study concerns the preliminary seakeeping analysis of a river barge of 3000 T with length of 90 m and two main loading conditions: full cargo and ballast. As environmental conditions the maximum wave heigh is 2 m, with whole range wave-barge heading angle, specific for all the river navigation zone. The maximum speed of the river barge is 15 km/h. The numerical analysis involves a linear seakeeping code by strip-theory method and short-term irregular waves approach, representing a preliminary simplified evalua-tion of the navigation capabilities of the river barge.
