Service and Operational Manuals — Navigation Equipment & DP

This volume will describe the technical features of the DPT 3500 system with DP2 Class certification. The system is a member of the SMC family configured for use as autopilot, trackpilot, speedpilot and DPT system. The DPT 3500 system is a product of the Imtech Marine & Offshore UniMacs 3000s Integrated Bridge System series.

The system functionality can be addressed by interfaces like Conning 3500 and DPT 3500 panel. Any DPT 3500 system is forming a part of the propulsion/steering control architecture of a ship. Such architecture generally differs from ship to ship, depending on the number of control positions, available actuators, and the manual control components.

The training manual for the SBC500 which is a SBC, standing for the single-board computer running the application software of a process control system. It is providing numerous functions and user interfaces.

These are the main function blocks are central processor and serial lines, dual ethernet, PBUS and piggy-back card interfaces, digital input/output, redundancy control signals, alarm monitoring and watchdog, front indicators/controls.

The SBC500 is technically based on the MPC755 RISC processor with a built-in floating point unit (FPU) and running the real-time operating system VxWorks...

The DP Capability and Motion Prediction Analysis functions are used to analyse and predict operational margins for your vessel and the effects of single-point failures. The basis for the analyses is the PRESENT environmental conditions (relative to the vessel heading) specified by the operator.

Due to the cyclic nature of the analysis program, i.e. that the analysis is run automatically at preset intervals, you should evaluate the PRESENT environmental conditions regularly, and input new values if they have changed significantly. Be aware that: - All directions are to be specified relative to compass north (TRUE NORTH); - The sea current amplitude is "real" current and not "DP" current. Both the DP Capability Analysis and the Motion Prediction Analysis functions can be run in On-line or Off-line mode.

When On-line Running mode is selected, online DP variables are used to adjust the calculations. Analyses are performed cyclically (usually every five minutes), provided the system has first settled for at least 2.5 minutes in Auto Position mode and with statuses PRESENT HEADING and PRESENT POSITION. These statuses are indicated on the status bar at the bottom of the screen. When the above stated conditions are met. the operator can also start a new analysis at any time.

Here is the seventh release of the official operator's manual for the K-POS stand-alone simulator developed by the Kongsberg specialists, intended to provide all necessary info. The publication starts with the history of the document, followed with the general overview providing required introductory information about this system, its configuration and main functions.

Then the separate chapter comes containing the operating procedures. The last section of the paper is dealing with the simulator settings including the important technical restrictions, dialog box and noise settings of the simulator.

The content has been worked out intending as a reference for the K-POS operators. This manual commences with a concise Glossary of terms/abbreviations used throughout the paper plus in all relevant documents. This volume will provide system users with required theoretical background and the user interface.

It covers technical aspects of the K-POS, e.g. settings and calibration of the joystick, different messages including diagnostics, alarms and operational checks, sensors including VRS, speed, draught and rate-of-turn sensors, gyrocompasses, instructions on changing the setpoints of the ship's position and heading, controllers, thrusters, power systems etc.

This technical doc relates to the Kongsberg K-Thrust RCS system offering manual remote controlling of the electric propulsion and steering gears and thrusters. Combined with all capabilities of K-Pos DP, K-thrust system turns into a maneuvering system providing full range of the vessel handling functions, e.g. manual and auto piloting, and joystick control with the option of the auto heading, automatic station keeping.

The K-Thrust RCS concept covers a broad range of panes and controllers that could be arranged in literally any combination on the bridge, in the ECR and other locations, for the control of the propulsion, steering gear and thrusters. The hardware/software platform of K-Thrust RCS has been particularly adapted to be integrated with K-Pos. Navigation (K-Bridge) and vessel control (K-Chief) systems.

The Kongsberg Simrad GreenDP® (SDP) system is a computerized DP control system enabling automatic heading/position controls of a vessel. The system operator specifies the setpoints for position/heading; then, they shall be processed by the SDP system to provide thrust control signals to the ship's thruster plus main propeller systems.

The propulsion units which are currently in use are allocated optimum thrust by the system. The SDP system uses the information obtained from the gyrocompasses in order to control the ship's heading, and minimum one PRS, i.e. position reference system, lets the system control the position.

The cJoy wing terminal - cJoy WT (cWing) - has been designed and developed to serve as a remote joystick terminal in stand-alone joystick systems (cJoy) and DPS, i.e. dynamic positioning systems (cPos and K-Pos). The wing terminal provides all necessary facilities for manual joystick and automatic heading operations, and is designed for installation in an outside environment.

The layout of the wing terminal panel is divided into three main areas where controls and indicators are arranged according to their function. A must-have document for all personnel directly involved in the operation and maintenance of the subject systems.
