How do snubber supports work in dynamic conditions?

Snubbers are activated when either a threshold acceleration (hydraulic snubbers) or threshold velocity (mechanical snubbers) is reached. At that point, the snubber is activated either via a valve system (hydraulic snubbers) or spring loaded mechanical stop (mechanical snubbers) to lock in position and act as a restraint device to prevent further movement of the pipeline.
