Improvement of the heave motion of a semi-submersible platform with damping sheets subjected to sea waves
In this study, the damping sheets were attached to a semi-submersible platform to mitigate the heave motions. We first examined a typical GVA4000 semi-sub under a monochromatic linear wave train in deep water. an analytical method based on diffraction theory was used to determine the heave motion response. The results revealed that the analytical results show good agreement with available exper...
متن کاملStudy on a Mechanical Semi-Active Heave Compensation System of Drill String for Use on Floating Drilling Platform
There are some disadvantages for existing heave compensation systems of drill string used for the Floating Drilling Platform (FDP), including high energy consumption, large and complex structure, and expensive manufacturing and maintenance costs. In view of the above, we present a streamlined mechanical semi-active heave compensation system (MSAHC) in this study. This system consists of active ...
متن کاملIntegrated System Design for a Large Wind Turbine Supported on a Moored Semi-Submersible Platform
Over the past few decades, wind energy has emerged as an alternative to conventional power generation that is economical, environmentally friendly and, importantly, renewable. Specifically, offshore wind energy is being considered by a number of countries to harness the stronger and more consistent wind resource compared to that over land. To meet the projected “20% energy from wind by 2030” sc...
متن کاملPredictive Control and Implementation of Mooring Automatic Positioning System for Deepwater Semi-Submersible Platform
The automatic positioning control of mooring system for deepwater semi-submersible platform has become a key issue in the research and development field of deep-sea resources. The DualStage Actuator (DSA) proposed in this paper can replace the single actuator to achieve the high speed and high precision positioning by cooperative control. The relative model and control algorithm of motion traje...
