摘要

AbstractA 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.Highlights•This paper deals with a floating storage device including several modular tanks with barges. The barges provide space for workers quarters and so on. Modular tanks are used for oil storage. In this paper,hydrodynamic responses of single tank is investigated with full and empty tank conditions. Fenders are installed on barges. The barge is assumed to be fixed to study the dynamic responses of the single tank.•Fender stiffness, different fender types, different water depths, as well as fender-tank gaps are investigated in detail.•Time Domain analysis is performed with environmental conditions such as wind, wave and current. Misalignment effect, viscosity effect and extreme wave response are studied. The time domain model can include nonlinear features involved in the response analysis.
