Service and Operational Manuals — Navigation Equipment & DP


We hereby introduce this C-Nav GPS System Operations Manual, originally released by C&C Technologies to describe the installation and subsequent configuration of the subject GPS and providing users with the detailed installation instructions for C-Nav GPS Receiver plus guidance on the use of the C-Nav Control (CnC) display Unit with its keypad and LCD screen display to control the operating parameters.

The document includes the tips on interfacing this System to a computer and other user equipment via the RS232 interfaces of the CnC Display Unit, information relating to the selection of NMEA messages supported by the C-Nav GPS Receiver, and connector pin-out diagrams for different cable connections. We would recommend you to get familiar with this publication in order to learn about the special features of the present product.

In the Auto Track mode, the vessel accurately follows a predefined track, described by a set of waypoints. The system controls the vessel to minimize the deviation from the track (cross-track error). The Auto Track mode covers low speed, high speed and move-up operations using different strategies for speed and heading control. In the Auto Track (low speed) mode, all the available thrusters are used to provide full position and heading control.

This strategy gives high-accuracy position control and allows full freedom in selecting the vessel heading, but its use is limited to speeds up to approximately three knots. This limit depends on the shape of the vessel's hull and the configuration of the propulsion system. The speed along the track is controlled very accurately with the possibility of running as slowly as a few centimetres per second. In the Auto Track (high speed) mode, the vessel heading is controlled (by default using rudder or thruster azimuth control, but may also apply bow thruster assistance depending on speed) to minimize the cross-track error while maintaining the required speed.

This strategy is suitable at normal cruising speeds, above 3 to 4 knots. When moving slowly in high speed tracking mode, additional thrusters may be used to assist in controlling the vessel heading. hi the Auro Track (move-up) mode, you can move the vessel a specified distance along the track. All the thrusters may be used to provide full position and heading control. The vessel stays on the track in a fixed position until you initiate a move-up.

The Autopilot mode enables the vessel to steer along a selected course by accurately and automatically controlling the vessel's heading. This mode is using the vessel's propellers and rudders or azimuth thrusters. The Autopilot (Heading control system) has a mark of conformity (wheelmark) as per MED requirements.

The vessel speed is controlled from the joystick on the operator's panel or from manual levers (requires the K-Thrust thruster control system). Reference made also to these sections of the relevant K-Pos (OS) Operator Manual' - Sensors; Joystick settings; Changing the heading setpoint; Alarm limits dialog box - Position page (heading limits); Heading dialog box - Rate Of Turn page; Thruster Allocation dialog box.

A K-Pos system with Follow Target mode has one of two available configurations: - Follow Single Mobile Target; - Follow Multiple Mobile Targets. Follow Single Mobile Target enables the ships to automatically follow the moving targets and keeps the vessel within a "position window" relative to the targets.

The moving target must be equipped with a mobile reference transponder or laser reflector in order for the K-Pos system to monitor its relative position. If, for example, the moving target is ROV, then the ship shall be equipped with the HPR, standing for the Hydroacoustic Position Reference system. In addition to a mobile reference transponder on the target, an additional fixed position-reference system is required, such as DGPS or a fixed transponder deployed on the seabed.

You can define a circle of operation within which the target can move without causing the ship to move. The vessel only moves when the target reaches the boundary of this circle. The radius of this circle (the "reaction radius") can be up to 1000 m.

The operator manual for the K-POS RAM - subject system allows to optimize the position of the ship during the drilling operations. The manual has been arranged in five sections. The first section provides the introduction to the system and description of its components and functions.

The second section contains the established operating procedures including settings, drilling configuration and display options etc., while the third sections is dedicated to the displayed Riser Angle info. The two remaining sections of the manual are dealing with the system messages and special features of the simulator/trainer.

This is the officially published user manual for the FanBeam system which has been specifically designed to provide the repetitive and accurate positioning and also tracking of the marine ships together with the static/semi-static anchored facilities. The documents starts with the short technical description of the system and its major applications.

The technical specifications of this system have also been provided; the installation tips cover all mechanical/electrical matters, mounting etc. The operation and maintenance are deal with in the next chapters of the doc covering both routine system maintenance and instructions on the fault finding. The remainder of the title addresses the data output formats.

The document starts with the information on the software versions and serial numbers, followed with the description of the components and instructions on mechanical installation of the system. The chapter dedicated to the cable installation gives their technical specifications and tips on connection.

The remaining chapters are dealing with the system console and DP feed connections, computer options, VFD screen, installation of the user console, data logging, set-up of the system console, creating the initial log file, and technical notes covering the message types, ethernet configuration, server upgrade, installation of the DSP image, FPGA firmware and antenna image, troubleshooting and also containing the reference checklist for the RPS.
