Barring a mechanical error—in these systems or, say, one ship's steering capacity—the collision likely resulted from a mistake, or a series of mistakes. "It's usually human error," Dyer says. Ships follow international "rules of the road" when they're in the same area, which specify how what actions to take in myriad situations, but there's no air traffic controller-equivalent giving instructions to keep everyone separated.
Most likely, the crews on one or both ships just did the wrong thing or miscalculated.
