study on effective arrangement of mooring lines of floating type combined renewable energy platform
Journal of Ocean Engineering and Technology, 2013Co-Authors: Joonmo Choung, Giyoung Jeon, Yooil KimAbstract:This paper presents the conceptual design procedure for the taut-leg mooring lines of a floating-type combined renewable energy platform. The basic configuration of the platform is determined based on an understanding of floating offshore plants. The main dimensions and mass distribution are determined based on a Hydrostatic Calculation. To identify the motion history of the floating platform and the tension history of the mooring lines, a hydrodynamic analysis is executed using Ansys.Aqwa. This helps in the selection of the best configuration for the mooring system such as the number of mooring lines, wire types, anchored positions, etc. In addition, the fatigue life of the mooring lines can be predicted from the tension history using the rain -flow cycle counting method.

fatigue design of mooring lines of floating type combined renewable energy platforms
International Journal of Ocean System Engineering, 2011Co-Authors: Joonmo Choung, Sangik Jeon, Minseong LeeAbstract:This paper presents the concept design procedure of a floating-type combined renewable energy platform based on hydrodynamic analyses and is focused on the fatigue design of taut-type mooring lines of the platform. Two types of combined renewable energy platforms are considered: a combination of wind turbine, wave turbine and photovoltaic energy plant and a combination of wind turbine, current turbine and photovoltaic energy plant. The basic configurations are conceptually determined from the understanding of floating offshore plants, while the main dimensions have been determined based on a Hydrostatic Calculation. Fully coupled hydrodynamic analyses have been carried out to identify the motion characteristics of the floating body and the tension histories of the mooring lines. The tension history is used for the fatigue life prediction based on the rain-flow cycle counting method. For the fatigue life prediction, tension life curves from API and the Palmgren-Miner rule are employed.

A case of unconventional use of finite element method in ship Hydrostatic Calculation
International shipbuilding progress, 2006Co-Authors: M. D. Motok, T. RodicAbstract:The pontoon bridge, or so called The Bridge on the Barges, consisting of longitudinally connected standard inland barges, was to be built on the river Danube. The first step of the structural design was to evaluate vertical displacements and forces at the points of hinge connection of the barges, for various cases of traffic load distribution along the bridge. Instead of performing standard Hydrostatic Calculations of immersion and trim of the vessels, whole structure was modeled as a chain of rigid beams elastically supported by buoyancy - and analyzed using the finite element method.
