Is re-registration is required if the design pressure is temporarily de-rated?

[Yousef]

Clause 6.7 of AS 3788 states that de-rating is considered a form of re-rating, which may require re-registration. However, the standard does not explicitly address whether re-registration is necessary if the de-rating is only temporary, provided that all requirements outlined in clauses 6.7.2 and 6.7.3 are met until the next major shutdown.

Clarification is needed on whether temporary de-rating, with compliance to these clauses, necessitates re-registration.
