چکیده
Abstract The vibration and noise performance of the offshore platforms are significant factors affecting comfort physical mental health staff, also important indicators for evaluating status platforms. Based on principle structural dynamics, taking semi-submersible platform as research object, this article systematically comprehensively studies characteristics transfer laws some partial-frame structures to overall structure by combing theoretical derivation numerical simulation. Firstly, coupling dynamic model device-plate-platform is established, transmission from excitation source through system analyzed theoretically. Secondly, multimodal mechanism plate frame cabin discussed considering one. Finally, based structure, study complex multi-modal law carried out, which contributes coupled protection structure.

Effect of earthquake directional uncertainty on the seismic response of jacket-type offshore platform
In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...
متن کاملNonlinear statics analysis of on offshore jaket platform in the case of explosion
Explosion and fire on an offshore rig can lead to its minor or complete damage and sinking which means the loss of life or environmental pollution. Hence the use of techniques such as blast wall is crucial to reduce the detrimental effects. These blast walls are designed for explosion wave of length between 0.1 to 1 of load mainly to protect the personnel and critical sections. In this research...
متن کاملEffect of Platform Surge Motion on the Performance of 5MW NREL Offshore Floating Wind Turbine
In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...
متن کاملSLOT : A research platform for investigating multimodal communication JAN
When two humans communicate with each other in a face-to-face situation, they do not only exchange speech. Other so-called channels or modalities, such as gaze (e.g., eye contact), facial expression, intonation, voice quality, and gestures (e.g., pointing) also play an important role in both the semantic and the socio-emotional aspects of communication (see, e.g., Ellsworth & Ludwig, 1972). Som...
