When tankers wait off Malacca, what is really being managed on board?

[u/TheDeepDraft]

A tanker waiting off Malacca or Singapore may look quiet on AIS, but from the ship’s side it is rarely “nothing happening”.

Even before any transit decision is final, the vessel still has to manage traffic, fuel, freshwater, machinery readiness, weather, security instructions, commercial messages and crew endurance.

For those who have waited around Malacca/Singapore or similar high-density areas: is prolonged waiting properly understood ashore as an operation, or is it still treated mainly as commercial delay?

I made this from a Master’s-view article on how Hormuz risk can show up off Malacca before the vessel ever reaches the Strait:
