“…The catamaran type platform that floats right on the surface of the sea water is moored at the bottom of the sea water, different from the figure 12-13 platform that goes into the water. The t urbine studied in the paper [16] is a type of vertical axis turbine. On the corner side of the floating building, it is connected by a rope attached to the anchor.…”

Scope for of research publications on ocean current energy has increased, resulting in high innovation from ocean energy technology and available models for numerical equations in article publications. Reviews for mapping studies on the development of technology and numerical equations are still rarely carried out. This review refers to articles that use equipment used at sea and are based only on ocean currents for research. From a variety of results of the investigation, it can be expected to be used as material for further studies to find research materials that can be discussed collectively or need to be handled further. The objective of present review study is scanning condition of technology used for analysis and find out the types of numerical equations that are often used in papers in recent years. The result is that various areas of innovation have been investigated in current energy conversion technologies that increase performance and durability and reduce the impact on the environment and have summarised alternative numerical analysis commonly used for current energy conversion technologies.

“…As a result of their renowned transverse stability, there is a significant chance that converting a catamaran into a FOWT support platform is worthwhile. A standard catamaran can be transformed into a platform for tidal energy according to various studies [60][61][62]. There is not much literature that emphasizes converting a catamaran into a useful support platform for operating wind turbines.…”

Offshore wind energy is a sustainable renewable energy source that is acquired by harnessing the force of the wind offshore, where the absence of obstructions allows the wind to travel at higher and more steady speeds. Offshore wind has recently grown in popularity because wind energy is more powerful offshore than on land. Prior to the development of floating structures, wind turbines could not be deployed in particularly deep or complicated seabed locations since they were dependent on fixed structures. With the advent of floating structures, which are moored to the seabed using flexible anchors, chains, or steel cables, wind turbines can now be placed far offshore. The deployment of floating wind turbines in deep waters is encouraged by several benefits, including steadier winds, less visual impact, and flexible acoustic noise requirements. A thorough understanding of the physics underlying the dynamic response of the floating offshore wind turbines, as well as various design principles and analysis methods, is necessary to fully compete with traditional energy sources such as fossil fuels. The present work offers a comprehensive review of the most recent state-of-the-art developments in the offshore wind turbine technology, including aerodynamics, hydromechanics, mooring, ice, and inertial loads. The existing design concepts and numerical models used to simulate the complex wind turbine dynamics are also presented, and their capabilities and limitations are discussed in detail.

“…This wave heading provide a greater excitation force and moment heave and roll motion of the ship than in other headings. The experimental results based on time domain are converted to the frequency domain using the Fast Fourier transform method which is presented in the response spectra as performed by [13], [14]. Furthermore, the hydrodynamic response results of model tests in irregular waves are analysed using the statistical value.…”

Installation and decommissioning activities of offshore structures often applied a floating crane barge for a lifting operation. The excessive movement response of lifted module affected by the motion of floating crane barge in waves can increase a large amplitude. However, the coupled motions of a floating crane barge and lifted module are not easy to predict accurately due to the dynamic movement of a lifted module and the complex coupling system. The coupled motion responses of a floating crane barge and a lifted module during lifting operation were investigated based on time domain by experimental method in this study. The model tests are carried out at Manoeuvring and Ocean Basin of Indonesian Hydrodynamic Laboratory, BRIN. The experimental conditions include the load cases of without and with a load of lifted module in crane tip, and the lifting operation was evaluated under irregular wave conditions. The experimental results show in that the phenomena of shift resonant frequency for the dynamic responses are clearly observed on the coupled motion of multibody system. The dynamic oscillations of the lifted module have a significant effect on the motion response of the floating crane barge. And the hoisting of lifted module has an obstructed effect on the rolling motion of crane barge.
