The three principles of mechanical protection are containment, deflection, and exclusion. Containment consists of deploying a barrier to hold the oil in place. Deflection consists of redirecting the moving oil either away from a sensitive area, or toward a containment site where recovery of the oil is more feasible. Exclusion consists of placing either temporary or permanent barriers to prevent oil from reaching an area. Mechanical protection protects the pipe from abrasion and impact loads.
