A study on the influence of bow thruster for turning ability [PDF]

open access: bronzeBulletin of the Korean society of Fisheries Technology, 2006
It is indispensable to grasp the turning ability of a ship to operate her effectively. For this purpose, the author measured the turning ability of training ship, A-RA by use of bow thruster and stem rudder. The turning ability of this ship, in case of using both of stem rudder and bow thruster at the same time, caused by increase of steering angle ...

CASE STUDY IN SYSTEMATIC DESIGN ENGINEERING – BOW THRUSTER COVERS

open access: diamondProceedings of the Canadian Engineering Education Association (CEEA), 2012
Students learning design engineering at times need a good example of procedure for novel design engineering. The systematic heuristic-strategic use of a theory to guide the design process – Engineering Design Science – and the methodical design process followed in this case study is only necessary in limited situations.

A Development of New Device for Bow Thruster Tunnel Grids [PDF]

open access: bronzeJournal of the Society of Naval Architects of Korea, 2006
For protection of the thruster against mechanical damage and reduction of tunnel resistance at ship forward speed, the tunnel grids are normally installed. Some of ship operators however, have a strong distrust of the protective function of the tunnel grids and so they do not want to install the protective grids for higher thruster efficiency.

MINIMIZING BED SCOUR INDUCED BY SHIP BOW-THRUSTERS BY USING QUAY WALL FLOW DEFLECTOR

open access: diamondMalaysian Journal of Civil Engineering, 2019
Recently, the combination of larger bow-thrusters installed with vessels have created higher levels of bed scour action affecting the berthing structure and its overall stability. Therefore, the bed near a quay wall structure must have sufficient strength by placing a bed protection which may cause the cost of the project to rise.

Combined CFX and Structural Simulation for Bow Thrusters Loading under Operating Conditions

open access: diamondJournal of Physics: Conference Series, 2018
The purpose of this paper is to simulate the bow thrusters loading under operating conditions installed onboard ships. The bow thrusters are specially designed to operate in seawater. In some cases the blades operate in difficult conditions like ice. The software analysis of the bow thrusters events associated to a jammed propeller blade is performed ...
