System Principles and Functionality
1.1 Introduction
This document describes the
NAVIS NavDP 4000
system.
NAVIS NavDP 4000
is a DP control system providing an
all-weather vessel motion control in different ways.
NAVIS NavDP 4000
is the family of systems.
More usual types are listed below.
Stand-alone single DP control system (DP-0)
NAVIS NavDP 4011 DP Control Station
Single DP system with integrated joystick system (DP-1)
NAVIS NavDP 4011 DP Control Station
NAVIS NavDP 4001 IJ Control Station
Dual-redundant DP system with integrated joystick system (DP-2)
NAVIS NavDP 4022 DP Control Station
NAVIS NavDP 4002 IJ Control Station
More detailed information see in Chapter 2, page 15.
With the system the Operator controls the vessel:
– moving;
– heading;
– position.
The calculations are done with allowance for the forces applied to a vessel like wind, current and waves.
NAVIS NavDP 4000 gets data both sensor and manual inputs. The manual input (position and heading settings) is
available in any mode.
To provide the specified moving the set of control signals (rpm, pitch or azimuth angles, etc.) for every thruster is
generated. The calculation is based on the received data.
NAVIS NavDP 4000 controls the vessel in three coordinate axes — surge, sway and yaw.
The coordinate values can be set in the following ways:
– manually — the operator set all coordinate values;
– automatically — all coordinate values are controlled automatically;
– automanually — some of coordinates are set manually while the others are controlled automatically.
Manual control is provided with joystick and rotary knob.
Information is displayed on the LCD with a touchscreen.
The touchscreen is used to set the information to display, to select a control mode and to enter data (setpoints, root
data, limitations, etc).
NAVIS NavDP 4000 applications are run under Windows 7 PRO.
