Hydrolock occurs when a cylinder is completely or partially filled with an incompressible fluid. In the worst case, hydrolock can damage the connecting rod and crankshaft. Slow turning reduces these risks significantly. In order to further reduce the risks of hydrolock during start up, we developed the Wärtsilä SafeStart slow turning system.

Implementing Wärtsilä SafeStart requires:
SafeStart also includes a start improvement function for Wärtsilä 32 engines where cranking revolutions are increased during the start sequence, significantly improving start reliability
Wärtsilä SafeStart is a standard feature in our newly built engines. It is also available as an upgrade for Wärtsilä 16V34SG, 20V34SG, and Wärtsilä 32 engines and requires a UNIC control system.
