EFFECT OF COAL LOADING CONDITIONS ON ELASTIC RESPONSE OF LARGE-SCALE FLOATING COAL STOCKYARD

Abstract

 This paper describes a large scale floating coal stockyard (LFCS) proposed in the paper and hydroelastic characteristics of it in regular waves. The LFCS with 590 m long and 160 m wide is capable of storage of half a million t maximum and off-loading of coals. It is expected to improve transport efficiency of coal sources in Kalimantan regions because of installing such as the LFCS offshore. At first, structural sections of the LFCS which must store huge weight of coals were designed and stabilities to deformation due to loading of coals with several cases of arrangements on the LFCS were discussed. In addition, stress distributions according to the arrangements were statistically analyzed with FEM. Applying a hydroelasticity analysis method with the Green function method combined with FEM for structural deformation, we investigated hydroelastic motions with various conditions of the arrangement. From the results, although the hydroelastic motions are different due to the loading arrangements and weight, its effect and the difference are not always large.
