The AVRIO LNG Cargo Handling Simulator is an advanced training platform replicating the operational, technical, and safety aspects of managing Liquefied Natural Gas (LNG) cargo. It provides a realistic and controlled environment for training maritime professionals in the specialized field of LNG handling, which is crucial given the hazardous nature of LNG and the complex systems involved in its transport and storage.

The LNG LCHS training program is structured to provide a comprehensive, hands-on learning experience for officers operating on LNG carriers. Spanning five days, the program is divided into daily exercises that simulate real-life LNG operations, covering the entire lifecycle of an LNG carrier—from delivery to drydock.

Key Features of the Program:

1. Structured Learning: Each day focuses on different operational aspects of the LNG carrier. Learners are introduced to procedures through the LNG LCHS Exercise Instruction Manual, which outlines the steps for each task in the simulator app.
2. Milestones: The exercises are broken down into milestones, ensuring that the learner understands and completes each step before progressing. Early milestones focus on preparing the simulator for the assessment.
3. Operational Knowledge: Learners gain a deep understanding of on-board LNG carrier operations, including machinery operation, valve management, and the limitations and troubleshooting procedures for various systems.
4. Simulator Assessment: Once the assessment phase begins, learners must respond to various alarms, remarks, and caution prompts from the online instructor. Alarms are categorized based on urgency—low and high priority. These are displayed on the right-side navigation bar of the simulator interface, where the learner can review them to understand the required actions. A complete list of Alarms and Remarks is provided for each exercise in the LNG LCHS Exercise Instruction Manual.
5. Alarm Handling: The learner must manage the Remarks and Cautions by resolving the issues directly. High-priority alarms require immediate action, while low-priority alarms may be deferred but still need attention.
6. Interactive Feedback: As learners interact with the simulator, they receive real-time feedback on their decisions. Alarms and instructor comments guide them through troubleshooting and operational processes, allowing them to understand the criticality of different situations.
7. Assessment Summary Report: Users can track their progress by selecting the Assessment Report option. The report provides details of each exercise attempt, including explanations for passing or failing specific attempts. Trend graphs are also displayed, offering insights into the actions performed throughout the assessment.

This training program is designed to simulate the full scope of responsibilities an officer might face on an LNG carrier, ensuring they are well-prepared for all aspects of ship operation and emergency response.

Important Note 1:

Please note on completion of every Exercise Assessment, The user has to close the simulator tab and return to the website Tab for the next exercise.

If the user fails to do so and has multiple simulator tabs opened, The user might fail the exercise due to conflicts caused by multiple tabs being opened.

Important Note 2:

The Simulator Familiarisation Exercise is designed to help the learner navigate and operate across various user interface screens within the simulator. Through a series of milestones, the learner interacts with different screens and completes tasks to gain a deeper understanding of the system’s operations. The exercise covers key aspects such as the requirements and procedures for operating different machinery, including the custody transfer system, generators in the power management system, and ballast pumps.

The learner will become familiar with crucial operational procedures, including the interlocks and parameters for starting various equipment. For example, they will learn the process for starting and operating cargo pumps, managing the connection and disconnection of manifold arms, and ensuring proper alignment between different system screens (e.g., verifying that valve positions on one screen correspond to others).

Other important tasks covered in the simulator include operating the water curtain system, positioning sampling points, and managing gas instruments. The learner will also gain a detailed understanding of the interlocks involved in safely starting and operating machinery such as ballast pumps, cargo pumps, and other essential components.

By the end of the exercise, the user will have a comprehensive understanding of how to navigate through the different simulator screens, access various areas, and operate the systems safely and effectively.
