The resonance of a floating tension leg platform (TLP) excited by the third-harmonic force of a regular wave is investigated based on fully nonlinear theory with a higher order boundary element method (BEM). The total wave elevation and the total velocity potential are separated into two parts, based on the incoming wave from infinity and the disturbed potential by the body. A numerical radiati...

In 15 patients with spastic hemiparesis the development of tension of calf muscles in relation to their electrical activation and their stretching period was studied on both sides during locomotion. Only in the spastic leg did isolated small biphasic potentials appear in the gastrocnemius E.M.G. with monosynaptic latency at the beginning of the stance phase, while the remaining gastrocnemius ac...

The open-source code DualSPHysics, based on the Smoothed Particle Hydrodynamics method for solving fluid mechanics problems, defines a complete numerical environment simulating interaction of floating structures with ocean waves, and includes external libraries to simulate kinematic- dynamic-type restrictions. In this work, full validation SPH framework using experimental data available an test...

Tension Leg Platform (TLP) adalah anjungan lepas pantai yang biasanya digunakan untuk kegiatan eksplorasi migas di laut dalam. Salah satu permasalahan sering terjadi goncangan TLP sebagai respon terhadap gelombang laut. Pada kondisi tertentu, terutama dalam samudra, ini dapat mengakibatkan berbagai gangguan, bahkan berpotensi merusak struktur. artikel diusulkan penggunaan ponton bertelapak sili...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

In this paper, the behavior of a typical jack-up platform under accidental loading of ship collision was investigated. The studied platform was modeled using ANSYS software and analyzed dynamically under ship impact. The platform was also analyzed dynamically under secondary ship impact. The initial collision results showed that the main energy absorption mechanism in impact to jack-up platform...

Abstract. The global floating offshore wind energy industry is rapidly maturing, with several technologies having been installed at pilot and demonstration scales. As the progresses to full array-scale deployments, optimization of marine activities related installation, operation maintenance, decommissioning presents a significant opportunity for cost reduction. This paper reviews various opera...
