ABSTRACT

Operability of a floating pier is investigated by analyzing inclination of the floating pier due to movement of cargos and cranes, motion response of a ship due to the neighboring floating pier. Assurance of survivability under harsh environmental conditions is a more important design concern to show usefulness of a floating pier, a simplified frequency-domain analysis and a time domain transient analysis are applied to evaluate mooring performance of the floating pier. A HOBEM (Higher-Order Boundary Element Method) is applied to frequency-domain analysis considering multi-body hydrodynamic interactions. FEM (Finite Element Method) is employed to investigate transient response due to very steep incident wave caused typhoon or tsunami.

INTRODUCTION

Recently, the size of container ships is rapidly increasing and the capacity of container ships is expected to be 15,000 TEU in a few years. For such a huge capacity container ship, an efficient cargo handling system is a very important consideration as a hub port. Consequently, dual port loading and unloading system is considered as one of important requirements for the hub-pier which can attract such a huge container ship. In this paper, a floating pier is considered as an efficient way to easily modify and upgrade existing ports and harbors so as to have a dual port cargo handling function.

In this paper, operability is investigated by analyzing inclination of the floating pier due to movement of cargos and cranes, motion response of a ship due to the neighboring floating pier under wave conditions. Assurance of survivability under harsh environmental conditions is a more important design concern to show usefulness of a floating pier, a simplified frequency-domain analysis and a time domain transient analysis are applied to evaluate mooring performance of the floating pier.
