... generator. While magnetofluid wave energy generating device is a new type of wave energy generating device. It is different from the traditional wave energy device which has a three-level energy conversion(You Yage,2003). Magnetic fluid wave energy generating device has only two-level energy conversion, one...

... ABSTRACT In this paper, a performance analysis model of heaving float wave energy converter/conversion (WEC) with liquid metal (LM) magnetohydrodynamics (MHD) generator (LMMHD-WEC) was developed. Performance analysis was carried out and a 5kW LMMHD- WEC prototype device with system efficiency...

This paper provides an overview of the challenges and discusses various aspects of a redeployment project represented risk to the integrity of a facility and the required inspection and repair and verification requirements for assessment and maintaining...

... azimuth thrusters to allow a safe and efficient installation of the platform. This novel upgrade was performed for the sole purpose of achieving overall cost and time efficiencies during the installation phase of this project, and was the first conversion of its type in the oil and gas and marine...

..., this paper proposes an application of adopting a wave energy conversion (WEC) device as their permanent or semi-permanent power source. Numerical simulations of the motions of a buoy are performed by the wave-body analysis software, COUPLE. Based on the predicted motions of a buoy, produced electrical energy...

... moment (TM) using theoretical or FEM (Finite Element Method) relations. However, TM conversion has still technical issues because torsion induced strains are different with loading modes due to warping effect. This study investigates and compares various conversion modes in TM measurement. Test results...

... and inertia, thereby increasing the vessel excitation, particularly, for the roll degree of freedom. Overall, it is concluded that the riser system design for this specialized ship conversion is considered to be feasible, regardless of the variations in the input data. hydrodynamic analysis td...

... ABSTRACT Oscillating water column wave power plants (OWC) are widely used in the ocean wave energy conversion. It is universally accepted that for a good efficiency of the plant, the turbine and the chamber should matched each other according to the wave climate site. The damping applied...

...). Usually, wave energy conversion can be divided into two steps (Falnes, 2007): primary conversion wave energy transferred from sea to oscillating system, and second conversion captured mechanical energy converted into other form, such as electric. Since the sea surface varies in wave frequency domain...
