What is the recommended testing approach for compartments with double-walled bulkheads?

Testing compartments with double-walled bulkheads at the same time is the recommended approach because this method ensures a comprehensive evaluation of the entire system's integrity and performance. By conducting simultaneous tests, potential leaks or structural weaknesses that may exist between or within the bulkheads can be detected more effectively, ensuring that the interconnected system is functioning as intended.

Simultaneous testing allows for a more holistic understanding of how the compartments interact with each other, particularly in the context of pressure differences or liquid containment. It also streamlines the testing process, reducing the likelihood of introducing variables that can affect the outcomes of sequential or staggered tests.

Testing compartments individually or at different times can create gaps in the assessment, potentially overlooking issues that might arise only when the compartments are under the same operating conditions. Sequential testing can also cause situations where one compartment influences the results of another, leading to inaccurate or incomplete assessments. Therefore, simultaneous testing is the best practice for ensuring the safety and efficiency of storage systems with double-walled bulkheads.
