Abstract
A modular floating concept for oil storage is proposed. The concept, which is advantageous for space-constrained locations, is composed of several modular floating tanks and barges. The floating multi-body hydrodynamic interaction of barges are studied in this paper. In the analysis, a single barge and then two-barge system are firstly analyzed to investigate the hydrodynamic interaction effect. More bodies are involved in the subsequent investigation. This study provides physical principles for different basic scenarios, and practical insights into how the hydrodynamic interaction problem affect the multi-body floating system.
