The modern offshore patrol vessel is designed to carry out various Fall entertaining missions in the management of economic exclusion zones, thus having some speed of service.For example, the speed for slow patrol is 10 knots, regular patrols 18 knots and chasing 22 knots.This condition requires a flexible propulsion system, which is combination of mechanical and electrical propulsion system.The application of this propulsion system to the OPV can increase the load factor of the propulsion system, resulting in lower fuel consumption than when using a mechanical propulsion system.

Based on Rocker Panel feasibility analysis results, the choice of combination of mechanical and electrical propulsion system is more advantageous than mechanical propulsion system, although investment and maintenance cost is higher.Therefore, patrol boats should use combination of mechanical and electrical propulsion system.
