Small and compact, but operating on the open sea, offshore patrol vessels take on a very broad range of missions that include search and rescue, maritime surveillance, environmental monitoring, and fishery protection.

While the engine load profile for a patrol boat has to be very flexible, especially in low-load areas, it also has to deliver a quick, high-power response, endurance, and faultless operation during any mission.

Therefore, our engines are specially designed to enable operation in patrolling mode as well as during sprints with maximum speed. What`s more, we offer you the highest level of flexibility for designing your vessel with solutions for both mechanical and hybrid electric propulsion.

Corvettes, frigates, and destroyers depend on high-powered, efficient engines that won’t let their crews down or risk the success of their missions – whether on far-from-home deployments or fast escort operations.

Silent and swift

Naval combatant applications usually require high speed for fast escort operations, without toleration of any compromise on acoustic, thermal, and visual signatures. They also have to withstand shocks or even cope with the strictest structure and airborne noise requirements. 

Our powerful and compact engines deliver this level of performance while ensuring maximum availability and outstanding specific fuel oil consumption (SFOC). Best-in-class life cycle costs are supported by our effective logistics and services organization across the globe.

Naval amphibious and support ships transport troops and supplies over long distances. Non-military deployment can be just as challenging. In disaster relief operations, the ships can act as hospitals, crisis management units, communications centers or helicopter platforms.

High expectations

Amphibious and support ships face great demands, including a long operational life. Worldwide logistic support missions can be long in range and duration. The propulsion systems must offer ultimate shock resistance, silent operation and low visual or infrared signatures. By offering reliable, high-power operation at low fuel consumption, our engines pass the test in terms of reliability and economy. What is more, our systems include powerful generating sets for integrated electric and hybrid plants, fulfilling all conceivable naval requirements to secure reliable, economical power generation and intelligent power distribution.

Inshore and fast patrol crafts cover a multitude of coastguard duties, including search and rescue, firefighting, environmental surveillance, border control, customs and police duties. In a military context, they can be deployed as littoral combat crafts, protecting infrastructure or in special operations.

Ease of use

Due to frequent operations in in coastal waters, engines for inshore patrol craft usually have very high emission compliance standards (IMO Tier III). Performance, extremely fast load response and permanent availability are a matter of course.

The typically small crews on these boats have their own specialized duties, such as rescue, inspection, and combat. That means that simple engine operation and maintenance are essential design features of our solutions.

More than an engine

MAN Energy Solutions has a strong track record in the engineering, integration and servicing of complete propulsion packages (including main engines, electric motors, variable frequency drives, gearboxes, propellers, and propulsion control systems) for navies and coastguards across the globe. We know what you expect: high propulsion performance and operational availability. In case of a hybrid propulsion solution with batteries, electric motors, a smart power management and an optimized drive control system is required, MAN consults you with a state of the art concept and supplies everything out of one hand.

Highly efficient propellers

Our propellers can be found on many types of ships – from small coastal cutters or supply and inspection vessels to larger, more powerful OPVs, command support vessels and frigates.

We offer propellers with a great variety of optimized design profiles for our four- and five-blade series (CPP / FPP), efficiently handling shaft powers up to 50 MW.

This impressive portfolio of products also includes a variety of shafting solutions including water-lubricated stern tube systems. Always customized propeller solutions, which can cater for shock impact and mission-critical conditions – contribute to forceful and energy-efficient operation with low hydro-acoustics and minimal environmental influence.
