When a ship is out in the deep ocean, how do they stay stationary without an anchor?

Question

RE: Titanic dives, there’s no way there’s an anchor that long, so how does the ship stay in place over the wreckage without drifting with the current?

Answer 1

They mostly don’t. There is no reason to stay stationary in the ocean. If ships want to stop for whatever reason, they might just shut down and drift, or steam at minimum speed against the current/wind.

There is also something called dynamic positioning. It is a system that helps ships maneuver and hold position. Ships that do underwater operations, cable laying, etc, might use dynamic position to ensure they remain in their exact positions.
