What does "as built/as certified" confirm about a system?

The phrase "as built/as certified" specifically refers to the condition of a system at the time it was completed and verified. This confirms that the system is certified in a specified configuration, meaning that it has been built and documented in accordance with the design specifications and standards set forth during the engineering and construction phases. This certification process ensures that all components meet the required criteria, including design, materials, and installation practices.

The importance of this verification lies in its role in ensuring reliability and safety in operation. By confirming the system is in a specific configuration, it also facilitates future maintenance, inspections, or modifications, providing a baseline for what is accepted as 'correct' in terms of performance and safety standards. This is crucial for both operational integrity and compliance in regulated industries, such as those involving diving operations and life support systems.
