Dynamic Positioning System
What is Dynamic Positioning System?
A Dynamic Positioning System (DPS) is an advanced computer-controlled system that automatically maintains the vessel’s position and heading using its own propellers and thrusters. This system is crucial for operations where precise positioning is required, such as offshore drilling, cable laying, diving support, and other marine activities where anchoring is not feasible or practical.
Function and Operation
Control System: The DPS relies on a central computer system that processes data from various sensors and references to control the ship’s thrusters and propellers.
Position Reference Systems: These systems include GPS, laser-based sensors, and acoustic beacons that provide real-time data about the ship’s position relative to a fixed point.
Sensors: Various sensors, including wind sensors, motion sensors, and gyrocompasses, feed data into the control system to account for environmental factors like wind, waves, and currents.
Thrusters and Propellers: The system uses the ship’s thrusters and propellers to make real-time adjustments, counteracting any external forces that might cause the ship to drift.
Importance
- Safety: It prevents the ship from drifting, especially during critical operations where stability is essential.
- Efficiency: Reduces the need for anchoring, saving time and allowing operations in deeper waters.
- Precision: Ensures that the vessel remains in the exact position needed for operations, even in challenging environmental conditions.
Installation and Commissioning
Before installing a Dynamic Positioning System (DPS) on a ship, our specialists carefully plan the sensor placement, ensuring they are accessible, visible, and strategically positioned near key components like thrusters and propellers. We then establish the electrical connections and integrate the DPS with the ship’s control system. Following installation, we thoroughly test each sensor’s accuracy, configure the system settings, and validate its performance through detailed scenario testing to ensure precise and reliable positioning during critical marine operations.
Calibration and Certification
Calibration involves aligning the Dynamic Positioning System’s sensors with established standards to ensure accuracy. We recommend annual calibration to prevent system malfunctions. Our certification process ensures that the DPS meets industry standards and regulatory requirements. Our technicians conduct thorough assessments, review documentation, perform on-site inspections, and issue the necessary compliance certificates.
Repair, Service, and Maintenance
We offer comprehensive repair, service, and maintenance for Dynamic Positioning Systems (DPS) on ships to ensure their optimal performance and longevity. Regular inspections help us detect signs of wear, damage, or malfunctions, while functional tests verify the system’s proper operation. In case of unexpected issues, we quickly repair or replace faulty components. We also keep the DPS software updated to improve functionality. Our specialists are experienced in setting up and maintaining DPS equipment from reputable manufacturers, ensuring the system effectively maintains the ship’s position and heading during critical operations.
