This exercise is designed to help users understand the procedures required to introduce dry air into cargo tanks using an inert gas generator, with the goal of achieving tanks with zero moisture. The process involves introducing dry air with a low dew point into the tanks to replace the moist air inside.
Key Objectives:
- The exercise aims to ensure the user understands the steps and parameters necessary to successfully complete the drying operation.
- The user will be guided through various milestones, including starting and operating multi-gas detectors and dew point meters, which are essential for monitoring the atmosphere inside the tanks during the drying process.
Exercise Breakdown:
- System Preparation:
- The user is shown how to correctly install the necessary equipment, including gas detectors and dew point meters.
- The procedure for preparing the inert gas generator in dry air mode is also explained.
- Monitoring the Process:
- Once the inert gas generator is started and dry air is introduced into the system, the user is instructed to continuously monitor the tank atmosphere using portable gas-measuring equipment.
- The user will track the progress of the drying process, ensuring the moisture is being effectively replaced by dry air.
- Completion and Assessment:
- The exercise concludes when the indicators show that the dry air has successfully replaced the moist air inside the tanks.
- The user must stop the supply of dry air once the required dew point has been achieved for all cargo tanks and systems.
This exercise provides hands-on experience in operating the inert gas generator, monitoring the tank atmosphere, and ensuring successful moisture removal to maintain safe conditions within the cargo tanks.
