POWERPACK

Hydraulic powerpack
A stand-alone diesel engine with a hydraulic pump, dedicated to driving a hydraulic system
Although most hydraulic systems will use the propulsion engines or genset engine as the prime mover, there are some circumstances
where a powerpack is necessary or more economical to operate, including:

• When adequate power for hydraulic applications is not available from propulsion or genset engines
• When running large propulsion engines or genset engines to power relatively small hydraulic power needs consumes excessive
quantities of fuel, is uneconomical and over time, damaging to the propulsion or genset engines through
under-loading
• When station holding can be accomplished by thrusters only without running main propulsion engines
• On some towed workboats and barges which do not have propulsion engines but which can be maneuvered around a worksite
on thrusters only
• When some functions conventionally powered by electricity can be driven hydraulically, substantially reducing genset size
• When propulsion transmission is completely hydraulic, as in some single engine catamarans
• When a hydraulically driven “pony” shaft and feathering propeller is installed in the hull as a “get-you-home” drive to save the
day in the event of main engine failure. (This concept is also particularly useful (and comforting) on single engine trawlers and
similar vessels equipped with PTO fitted gensets.)
Typically a VETUS powerpack will consist of an M or VH series diesel engine with an appropriately sized hydraulic pump (variable
volume, load-sensing or vane type depending upon the application) mounted on an adaptor plate in place of a gearbox.
VETUS diesel engines meet all European emission requirements but at the time of publication of this catalogue are not EPA certified
for use in the USA or Canada. If the powerpack is entirely devoted to propulsion, then its diesel engine will be controlled by a
throttle lever, but in a multiple user-device system with a load sensing pump an electronic control will be fitted to the powerpack
engine.

As with all VETUS hydraulic systems, a customer support engineer will work with you to configure the powerpack and related
systems to suit your vessel and its needs.
There are three VETUS powerpack models available:
PPM435
PPM445
PPH465
