• V-manifold
• Orbifold
• Orbifold fundamental group
• Culler-Morgan-Shalen theory
• Incompressible

We make an analogy of Culler-Morgan-Shalen theory for 3-orbifolds. Our main goal is to show that there exists a non-empty system of incompressible and not boundary parallel 2-suborbifolds respecting a graph product of the orbifold fundamental group.
