Description

TECHNICAL FIELD

[0001] The present application relates to a rudder control method for a dynamically positioned vessel. BACKGROUND

[0002] At present, ocean engineering vessels with dynamic positioning function, according to different customer use requirements, the selection form of the propeller and the rudder will be slightly different, some vessels use full rotation propeller (a kind of screw or ducted propeller which can rotate 360° around the vertical axis), the rudder force is generated by the rotation of the propeller itself; many vessels still use the form of combined propulsion of propeller and rudder, the rudder control system of ordinary merchant ship is usually controlled by automatic rudder system, which mainly includes automatic rudder, follow-up rudder and non-follow-up rudder three operation modes, for ocean engineering vessels with dynamic positioning function, if the traditional propeller and rudder form is used, the rudder needs to install an independent control system to meet the above use requirements, so the system is relatively complicated and the crew operation is prone to errors. SUMMARY

[0003] The purpose of the present application is to provide a rudder control method for a dynamically positioned vessel.

[0004] The technical scheme adopted by the present application to achieve the above purpose is as follows: a rudder control method for a dynamically positioned vessel, comprising the following steps:

[0005] Step 1, when the rudder control function is switched from follow-up rudder mode to dynamic positioning system control mode, the control position is switched from the front console to the rear console, the follow-up rudder / dynamic positioning mode button (1) of the rudder control function mode switching controller is pressed, at the same time the follow-up rudder / dynamic positioning mode button (1) indicator light is on, the automatic rudder control system rudder control function mode has been set to follow-up rudder / dynamic positioning mode, at this time the steering position is in follow-up steering mode state, the follow-up rudder mode in use indicator light (11) of the steering position conversion control panel is on, if the mode switching is unsuccessful, the switching fault alarm (5) will issue an alarm, when the dynamic positioning system control station issues an instruction to apply for the steering right, the front console to rear console position switching alarm (9) of the steering position conversion control panel issues an alarm, at this time the front console to rear console confirmation button (7) is pressed, at the same time the front console to rear console confirmation button (7) indicator light is on, the follow-up rudder mode in use indicator light (11) of the steering position conversion control panel is off, at this time the rudder control is switched from follow-up rudder mode to dynamic positioning system control mode, and the steering position is switched from the front console to the rear console;

[0006] Step 2, when the rudder control function is switched from the dynamic positioning system control mode to the automatic rudder control system mode, the control position is switched from the bridge background to the foreground, the bridge background to the foreground position switching alarm (10) on the steering position conversion control panel sends an alarm after the dynamic positioning system control station issues an application for returning the steering right instruction, at this time, the bridge background to the foreground confirmation button (8) is pressed, at the same time, the bridge background to the foreground confirmation button (8) indication light is on, the rudder position conversion control panel on the follow-up rudder mode in use indication light (11) is on, at this time, the rudder control is switched from the dynamic positioning system control mode to the follow-up rudder mode, and the steering position is switched from the bridge background to the foreground.

[0007] In the step 1, the automatic mode button (2), the non-follow-up rudder independent mode button (3), the non-follow-up rudder synchronous mode button (4) and the control panel indication light brightness adjuster (6) are further arranged on the rudder control function mode switching controller.

[0008] In the step 1 and the step 2, the steering position conversion control panel indication light brightness adjuster (12) is further arranged on the steering position conversion control panel.

[0009] The rudder control method for the dynamic positioning function ship is used for controlling the rudder by the automatic rudder system, without the need of additionally installing an independent rudder control system, the system configuration has a higher integration degree, and the crew operation is relatively simple.
