2016 IEEE International Conference on Underwater System Technology: Theory and Applications (USYS), 2016
This paper presents the thruster modeling for a Hovering Autonomous Underwater Vehicle developed by Underwater, Control, and Robotics Group. Bollard-pull experiments are done to find the relationship between axial forces generated by thrusters and input signal given to Arduino Uno board in degree, taking into account the effect of thruster-thruster and

Numerical Prediction of Thruster-Thruster Interaction
Volume 4: Ocean Engineering; Ocean Renewable Energy; Ocean Space Utilization, Parts A and B, 2009Many vessels deploying offshore activities nowadays are dynamically positioned by multiple azimuth thrusters instead of anchors. The multiple propulsor set up, gives a considerable flexibility to work fast and accurate. Due to the fact that the thrusters are positioned relative close to one another their performance is influenced.

Offshore Technology Conference, 1975
ABSTRACT The large powers required for dynamic station keeping of offshore drilling platforms have to be transmitted into the highest possible thrust, exerted at the location and in the direction required. This paper gives information on hydrodynamic characteristics of controllable pitch propellers and thrusters for

Vessel Thruster-Thruster Interactions During Azimuthing Operations
24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 1, Parts A and B, 2005Flow interaction between thrusters is important, as many offshore vessels are equipped with rotating (azimuthing) thrusters for ease of manoeuvring and dynamic positioning. Accurate prediction of available thrust to resist horizontal environmental forces is essential allowing the realistic station-keeping capability of these vessels to be established ...

Stationary plasma thruster simulation
Computer Physics Communications, 2004Abstract A two-dimensional in space and three-dimensional in velocity, fully kinetic particle-in-cell (PIC) model of the atom (Xe), ion (Xe+) and electron dynamics of a stationary plasma thruster is developed. Electron-neutral elastic scattering, excitation and ionization processes are modelled by Monte Carlo collision methodology. The interaction of
