Marine Propulsion System targets planing applications.
Press Release Summary:
Coupled to 13 L marine diesel engine, IPS1050 Inboard Propulsion System generates equivalent of 1050 hp, suitable for workboats, passenger ferries, and patrol boats up to 30 m and 40 knots. System is available as double, triple, or quad engine installation with forward facing and counter-rotating propellers. Acceleration and shifting are done with twin, single lever controls. Joystick provides direction control, while Dynamic Positioning System holds boat's heading.

Volvo Penta IPS Marine Commercial Range
The leading pod for planing workboats
With the IPS system, Volvo Penta has introduced a pod system for planing applications, such as fast workboats, pilot boats and patrol boats. The IPS program is now being expanded still further. With new and larger drive units coupled to the 13 litre marine diesel, Volvo Penta is launching a new power class, IPS1050.
With forward-facing and counter-rotating propellers, the IPS system is the undisputed market leader in pod installations for planing craft. The first stage of the IPS system was based on Volvo Penta's 6-liter diesel engine. Last year, a new power class was launched with larger drive units and powered by Volvo Penta's 11-liter engine.
This year, Volvo Penta is launching a third stage based on its 13-liter marine diesel. The new IPS package generates the equivalent of 1050 hp, compared with conventional inboard installations. This means that Volvo Penta can now offer the IPS system for workboats, passenger ferries and patrol boats up to 30 meters and 40 knots.
More powerful pods
Larger engines with higher power output and higher torque make big demands on the drive units. With this in mind, Volvo Penta has developed a larger and even more powerful IPS unit as well as a completely new series of propellers for the IPS1050.
The larger drive unit has all the advantages and features that made the original IPS system so successful.
The underwater body and propellers have been developed with the help of advanced computerized models together with extensive cavitation tunnel tests and tests in boats. The result is a highly efficient integrated system for propulsion.
Cleaner and quieter
Higher efficiency than inboard shafts gives the IPS1050 better performance combined with lower fuel consumption and - not least - lower total emissions. In addition, noise and vibrations are substantially lower.
Volvo Penta covers the whole speed range for the IPS1050, from about 28 to about 40 knots, with seven highly efficient propeller packages, which are available as standard products. This gives significant advantages for both shipyards and owners.
13-liter engine
The engine for the new power class is Volvo Penta's 13-liter marine diesel D13, equipped with dual-stage turbo-charging technology and developing 800 horsepower. This 13-liter engine has been developed with the help of ultramodern diesel engine technology.
The dual-stage turbo-charging system has a first-stage twin-entry turbine that enables pulse-charging, which results in a very high torque from low rpm. At higher rpm, a second turbo gradually takes over, so the engine retains high power even at high rpm. The charge air is both inter-cooled and after-cooled.
EMS 2, the new engine control system developed by Volvo Penta, regulates fuel injection timing and pressure. The system controls the unit injectors, one per cylinder, which operate at a pressure of as much as 2000 bar and atomize the fuel for optimum combustion.
Total emissions satisfy - by a wide margin - the EU Inland waterways stage 3A, US EPA tier 2 for Marine Commercial and IMO tier 2, in force from January 2011.
Boats from 10 to 30 meters
The IPS system is offered as a double, triple or quad engine installation. This means that the IPS system covers boats from 10 meters all the way up to 30 meters.
There is no difference for the driver whether the boat is powered by two, three or four IPS systems. Acceleration and shifting are done in the same way with twin, single lever, controls. No additional controls are needed.
The IPS units are compact, which enables completely new and bold boat design solutions. Onboard space is much larger, while the time needed by the boat builders for installation is reduced by 50%, in some cases even more.
Functions for easy maneuvering
All Volvo Penta IPS models are available with a joystick. This lets the driver control the boat by simply moving the joystick in the direction he or she wants the boat to move - a great help in docking and other low-speed maneuvering. Also available is the Dynamic Positioning System that holds the boat's heading and keeps it within a very limited area. Twin high-precision GPS receivers determine the boat's position and heading. Special software transforms the data into steering angles, gear shifts and throttle positions to keep the boat still.
