Abstract
A modular floating concept for oil storage is proposed. The concept is composed of several modular floating tanks and barges. The floating tanks are self-stable and designed for storage of oil and hydrocarbon material. The barges provide platforms for equipment and workers quarters, and enclose the floating tanks through mooring fender systems. The whole concept is then moored by mooring dolphins. This concept is designed for finite water depth application, however, potential application for deep water condition is also investigated. In this study, only single floating tank is investigated with both empty and full tank conditions considered. Different mooring fender configuration designs are the focus. It is assumed that the barges are fixed in the study of single tank dynamic properties, and multi-body hydrodynamic is neglected. Different regular wave conditions are used for the study of the dynamic performance of the tank under various fender mooring system parameters. Irregular wave together with wind and current for 100 year return period are also applied for the study of the tank dynamic performance. At last, sensitivity study of the viscous effects is performed.
