Pre-DP Checklist: Ensuring Safe Transition to Dynamic Positioning Control
A Pre-DP Checklist is a critical operational tool used to ensure all systems and conditions are ready for the safe transfer of a vessel from conventional navigation to Dynamic Positioning (DP) control. This checklist is completed immediately before engaging the DP system and may include separate sections for the Bridge and the Machinery Control Room to address the unique responsibilities of each area.
Purpose of a Pre-DP Checklist
- Operational Readiness: Verifies that all DP-related systems are functioning correctly.
- Safety Assurance: Confirms that the vessel and its environment are safe for DP engagement.
- System Redundancy: Ensures that backups and redundancy measures are in place.
- Compliance: Meets industry standards and best practices for safe DP operations.
Typical Items in a Pre-DP Checklist
Bridge Section
- Position Reference Systems: Ensure sufficient PRS are active, calibrated, and providing reliable data.
- Gyro and Heading Sensors: Verify operational status and alignment.
- Environmental Sensors: Confirm wind, motion, and current sensors are functioning.
- DP Console: Test DP displays, alarms, and manual controls.
- Communication Systems: Check internal and external communication links, including links to the Machinery Control Room.
Machinery Control Room Section
- Power Management System (PMS): Confirm generators are online and synchronized, and blackout prevention is active.
- Thrusters: Verify readiness and test response to DP commands.
- Cooling and Lubrication Systems: Ensure all systems supporting thruster and engine operation are functioning.
- Fuel Supply: Confirm adequate fuel levels for planned operations.
- Alarm Systems: Test alarms for critical systems to ensure functionality.
Benefits of Using a Pre-DP Checklist
- Operational Safety: Reduces the likelihood of system failures during DP engagement.
- Consistency: Standardizes procedures for all crew members, minimizing human error.
- Proactive Issue Resolution: Identifies and resolves potential problems before DP operations begin.
- Compliance: Ensures adherence to industry regulations and classification society requirements.
