Scuttled
Scuttled is a term primarily used in maritime contexts and refers to the deliberate sinking of a vessel. This act is typically performed to prevent the ship from falling into enemy hands during wartime, a practice known as "scuttling." It can also be done to prevent an outdated or damaged vessel from becoming a navigational hazard, or to deliberately create an artificial reef for marine life.
The method of scuttling can vary. It often involves opening seacocks or sea valves to allow water
The term can also be used metaphorically to describe the deliberate abandonment or sabotage of a project
