“…Scaled models of mooring systems can be studied experimentally in wave tanks [90]. Some properties of mooring lines that should be modelled as accurately as possible are vertical and horizontal pretension components, vertical and horizontal stiffness, line mass, and drag characteristics [88].…”

An overview of the most important development stages of floating point absorber wave energy converters is presented. At a given location, the wave energy resource has to be first assessed for varying seasons. The mechanisms used to convert wave energy to usable energy vary for different wave energy conversion systems. The power output of the generator will have variations due to varying incident waves. The wave structure-interaction leads to modifications in the incident waves; thus, the power output is also affected. The device has to be stable enough to prevent itself from capsizing. The point absorber will give optimum performance when the incident wave frequencies correspond to the natural frequency of the device. The methods for calculating natural frequencies for pitching and heaving systems are presented. Mooring systems maintain the point absorber at the desired location. Various mooring configurations as well as the most commonly used materials for mooring lines are discussed. An overview of scaled modelling is also presented.

“…The influence of the pipe diameters to FB reflection is slight. Pena, Ferreras, and Tembleque (2011) breakwater experimentally under regular waves. Wu, Zhong, and Huang (2002) analyzed several factors impact wave attenuation efficacy of pipe-tyre floating breakwater experimentally and improved the buoyant raft structure from the rigidity of the raft body, tilt, wave dissipation area, and the natural frequency, proposed a superior pipe-tyre floating structure.…”

Wang, H.; Xu, H.; Liu, P.; Duan, J.; Chen, H., and Wang, B., 2015. Experimental study on the dissipation characteristics of curtain-type flexible floating breakwater.This paper presents the wave dissipation efficacy of the new curtain-type flexible floating breakwater (CFFB) with the implementation of 3D tank tests. It evaluates the influence of the presence of the upper plate, the incident wave height, wave period and other factors on the wave dissipation property of CFFB. The main structure of CFFB is united body which consists of wave dissipation blocks and flexible cables. It has been found that this new CFFB has superior characteristics of hydrodynamic and wave attenuation. ADDITIONAL INDEX WORDS:Curtain-type, flexible, experimental study, wave dissipation.

“…For example, two-dimensional and three-dimensional (3D) FBW experiments were conducted, in which the great influence that the wave obliquity has on the module connector forces was observed (Peña et al 2011). The model tests were carried out to investigate the effects of inner-tank sloshing on the global motion responses of a floating liquefied natural gas vessel (Zhao et al 2013).…”

KEYWORDSOffshore structure; hydrodynamic analysis; moored pontoon; physical model tests; finite water depthThe hydrodynamic analysis of pontoon-type floating structure interacting with waves is very important in offshore engineering. In this paper, both numerical and physical model tests have been carried out to investigate the hydrodynamic performances of a moored pontoon in finite depth water. The experiments were conducted with many cases with various wave periods under regular wave in a wave tank. Numerical simulations were carried out in the several conditions. The numerical results were compared with the consequences of the model tests. It is showed that the numerical results are in agreement with the model tests in majority cases, particularly, the change tendency of curves is essentially same in two ways. The motion responses of the floating pontoon, as well as the chain forces in different wave heights and wave angles were calculated with a wide range of wave periods by the numerical method to find out the influences of the wave parameters on the hydrodynamic properties of the moored barge. Based on the numerical and experimental results, some useful conclusions have been drawn in this paper.
