Description
Product Overview
The Kongsberg Simrad SDP/SJS OT (Operator Terminal) is a marine-grade human-machine interface designed for sophisticated Dynamic Positioning (DP) and Joystick Control Systems (JCS). Acting as the primary control bridge for vessel station-keeping and precision maneuvering, this operator system integrates tactile control joysticks, dedicated status panels, and a high-visibility visualization matrix. Built to withstand harsh maritime environments, it delivers deterministic communication and high fault-tolerance for demanding offshore, drilling, and specialized vessel operations.

Operational Guidelines
Power-Up / Power-Down Sequence
- Startup: Verify all physical thrusters, reference systems (DGPS, Fanbeam, etc.), and environmental sensors are powered and online. Turn on the main circuit breakers supplying the dual-redundant power units of the SDP/SJS OT. Allow the proprietary real-time operating system to fully initialize. Ensure the communication status indicators switch from red to green, proving a secure link to the process segment controllers.
- Shutdown: Transfer vessel control from Dynamic Positioning to standard manual thruster/steering bridge controls. In the system software terminal, initiate the formal “System Exit” routine to archive the active log files. Once the screen prompts that it is safe to do so, switch off the main console power switches and secure the auxiliary breaker inputs.
Step-by-Step Standard Operation
- Pre-Check: Conduct a full lamp, alarm, and console button test using the built-in system diagnostics.
- Sensor Selection: Access the sensor configuration panel on the console to activate and verify primary and secondary position reference strings.
- Mode Activation: Select “Joystick Mode” (SJS) for manual maneuvering, or transition to full “Dynamic Positioning Mode” (SDP) to lock the vessel onto the target coordinate vector.
- Environmental Input: Confirm wind, current, and wave feed-forward models are accurately calculating parameters relative to the vessel hull configuration.
- Monitoring: Actively watch the thruster allocation and power utilization graphs during the operation to maintain proper safety margins.
Frequently Asked Questions
Q: What should I do if the console warns of a “Position Reference Dropout”? A: Evaluate the stability of your secondary tracking systems on the display matrix immediately. If all positioning strings drop out, switch the console to manual joystick mode or manual thruster override to safely maintain control of the vessel.
Q: Can this terminal run on standard commercial office computer hardware? A: No. The SDP/SJS OT utilizes highly specialized, marine-certified industrial computing architectures paired with proprietary operating system baselines to ensure deterministic response times and strict failure immunity.
Q: How are dual-redundant networks handled by the operator system? A: The system communicates simultaneously over two fully independent network rings. If one bus cable suffers a hardware break or signal disruption, the terminal seamlessly utilizes the secondary channel without a drop in communication frames or a bump in operational control.
Q: How often do the mechanical joysticks require physical calibration? A: Joysticks are factory calibrated using contactless sensors; however, a manual software-zeroing procedure should be initiated via the engineer maintenance menu during regular annual vessel surveys.
