Furthermore, the sudden cessation of flow in the pipeline triggers transient pressure surges, known as water-hammer effects, which propagate as high-velocity shockwaves through the fluid column. These surges occur because the kinetic energy of the moving mass of oil must be instantly dissipated, resulting in extreme pressure spikes that can exceed the structural design limits of the steel.
