Préparation à la mise à l'eau de navires équipés d'airbags

Launching a ship with airbags de lancement de navires is an efficient and safe method, but only if you prepare properly. Good planning, proper equipment, and clear procedures are essential for a smooth and safe operation. This guide explains everything you need to know before using launching airbags, from preparation to final execution.

1. Preparation Before Launching

Before using airbags de lancement de navires, you need a solid preparation plan. Start by calculating the ship’s weight, dimensions, and center of gravity to select the right number and size of airbags. Evaluate the slipway conditions, including slope, soil strength, tides, and water depth. Make sure all equipment is ready, including airbags marins, compressors, pressure gauges, winches, towing lines, wedges, and safety gear. Assign clear roles to your team members, such as a launch director, safety officer, winch operators, and airbag technicians. Conduct a briefing before the operation to ensure everyone understands their tasks and communication signals. Proper planning, equipment checks, and teamwork greatly reduce the risk of accidents.

2. On-Site Preparation and Launching Process

This is the most critical part of the operation. Follow these steps carefully to ensure safety and success.

2.1 Clean and Prepare the Slipway

• Remove stones, screws, wood chips, and other sharp objects from the slipway.
• Uneven or dirty surfaces can damage airbags de lancement de navires and shorten their service life.
• Ensure the ground is level, dry, and free of oil or debris.

2.2 Position and Align the Airbags

• Place airbags based on the ship’s weight and hull structure.
• Keep airbags parallel to the ship’s centerline to prevent rolling or shifting.
• Use markers and wedges to secure airbags in place.

2.3 Inspect Airbags and Equipment

• Check each airbag for cracks, cuts, or excessive wear.
• Perform an air tightness test before use.
• Inspect valves, hoses, and compressors to avoid leaks or failures during the launch.

2.4 Inflate Airbags Properly

• Inflate gradually, starting at 30-40% of working pressure.
• Verify the position and adjust airbags before reaching full pressure.
• Ensure all airbags are inflated evenly to avoid unbalanced forces.

2.5 Launch the Ship

• Start towing slowly using winches or pulling devices.
• Maintain stable speed and keep constant communication between operators.
• Assign staff to monitor airbags and hull movement in real time.
• Stop immediately if airbags shift, deform, or show abnormal pressure.

2.6 Recover and Inspect Airbags

• After the launch, carefully collect airbags and clean them with fresh water.
• Remove sand, salt, and sharp debris from the surface.
• Inspect for damage and record any maintenance needs before storing.

3. Safety Management and Risk Control

Safety is always the top priority when working with airbags de lancement de navires. Follow these rules:

• Set up a safety zone and keep unauthorized personnel away.
• Prepare an emergency plan for possible incidents such as airbag failure, winch malfunction, or sudden weather changes.
• Stop the operation immediately if conditions become unsafe due to strong winds, heavy rain, or unexpected tides.
• Conduct a pre-launch safety briefing before every operation.

4. Troubleshooting Common Issues

5. Maintenance and Storage

Proper maintenance extends the lifespan of your airbags de lancement de navires:

• Clean airbags after every use and remove salt, mud, and debris.
• Store airbags in a dry, shaded area away from sunlight and chemicals.
• Perform regular pressure tests and inspections according to manufacturer guidelines.
• Keep detailed maintenance logs for future reference.

6. FAQ

Q: Why must I clean the slipway before using airbags?
A: Sharp debris like stones or screws can puncture airbags and shorten their service life.

Q: How many times can I reuse ship launching airbags?
A: With proper care, airbags can last for 5 to 8 years or hundreds of launches.

Q: What should I do if an airbag leaks during the launch?
A: Stop the operation, replace the faulty airbag, and check the system before resuming.
