The Frenchman made a last-minute stop after running hard tyres for most of the race in an attempt to gain from the handy timing from a safety car that never materialised for him.
When he finally came into the pits at the end of the penultimate lap, he found a group of people in the pit entry as the procedure for setting up parc ferme had started, as the FIA officials involved didn't realise that Ocon had yet to pit.
After the race, the Baku stewards met with the officials concerned and both parties agreed that changes should be made for Miami and beyond.
The stewards noted: "We walked through the relevant procedures and protocol with the FIA representatives in detail and required them to take immediate steps to reconsider these procedures and protocols with the relevant stakeholders (including FOM, the teams and the FIA) to ensure that this situation does not occur again.
"The FIA representatives expressed their regret at what happened and assured us that they would do so in time for the next event."
Some elements of the new procedures that relate directly to the teams were revealed in the post-race procedure document that is issued at every event.
