**should** any wreckage **be** found

.................

Australia, which is coordinating the search in the southern Indian Ocean, said it had established a new body to oversee the investigation and issued countries involved in the search a set of protocols to abide by should any wreckage be found.

I am wondering if my perception is correct?

My perception: **a set of protocols to abide by should any wreckage be found** really means " a set of rules to be obeyed if any wreckage would be found.
