PZM Comandante Toro

The Patrulleros de Zona Marítima (PZM) are a series of offshore patrol vessels being built for the Navies of Chile, Argentina and Colombia.

The patrol vessels operated by the Chilean Navy’s Coast Guard Service since 2008 are each equipped with two 12-cylinder Wärtsilä 26 main engines. Each engine drives a controllable-pitch propeller through a single-input Wärtsilä reduction gearbox. Wärtsilä also supplies the sterntube seals and the control systems for the engines and propellers.

A key factor in Wärtsilä winning the contract for the Chilean OPVs was the company’s ability to supply complete, integrated propulsion systems. Such complete solutions offer real benefits in terms of manufacturer support throughout the lifecycle of the vessel.

These ships will conduct defence missions in Chile’s Exclusive Economic Zone (EEZ), including the control and protection of maritime traffic, and logistical support for isolated locations.
