Volvo Penta’s new marine drivetrain, the IPS Professional Platform (Inboard Performance System) is capable of powering vessels up to 55 meters at top speeds of 12-50 knots, with electric & hybrid capabilities.
Highlights of the new platform include:
- Intelligent dual power drive system: Installed as a twin, triple, or quad system, each vessel can have four to eight power sources. It’s prepared for fully electric/hybrid power, renewable diesel, or HVO.
- Future-Proof: Vessels can be designed with today’s ICE technology, and upgraded to electric or hybrid in the future without the need to redesign or scrap a vessel.
- Smart Eco Mode: Automatically starts/stops individual engines based on the power needed for a given situation, optimizing fuel consumption, running hours, and service life.
- Advanced Sensors: Vibration sensors that provide data to help us make better decisions around maintenance and what captains should be reacting to.
Could you walk us through the IPS platform?
The IPS is a three-layer product: the powertrain in the vessel, the electronics umbrella, and integration at the helm.
It’s a forward-facing drive system, inserted through the hull, with counter-rotating dual propellers, and the drive unit is an integrated rudder itself. The system can be installed as double, triple, or quadruple drive, what we call ‘IPS legs’, each individually steerable and the complete system gives up to a 30% reduction compared to a traditional inboard shaft installation.
Inside the boat, you have an electronics layer that integrates both the steering of the parts and the power control, integrated with the helm station. We supply the steering wheel, throttle, joystick, navigation screens, gauges, etc. which we call the ‘glass cockpit’.
We don’t consider ourselves just a marine drive supplier, we’re more of a marine technology company supplying one integrated propulsion package.
Can you talk about the new updates?
We created the IPS platform about 20 years ago, and since then it’s become the market leader for yachts up to 120 feet but with the IPS Professional Platform, Volvo Penta will be able to support yachts up to 180 feet. The Professional Platform has added a few new key features:
Increased Size and Power
We’ve scaled the size up from 22 meters to 55 meters in serviceable length, capable of 12-50 knots thanks to the enhanced propellers, gear ratios, and twin drive input for each IPS drives. Since the vessel can have two, three, or four IPS drives in parallel, each with twin inputs, you have four, six, or eight power sources driving the vessel.
Eco Mode
The IPS Professional Platform has an intelligent ‘Eco Mode’ that automatically switches engines on or off depending on the power needed in that situation. For example, if you are navigating out of a harbor, you don’t need a lot of power, so the system will only use one single engine and switch the others off. It monitors the service life of each engine and adjusts accordingly to keep them in sync. If one engine has 90 hours, and another has 110, the system will start with the 90-hour engine to maintain balance. This feature not only saves fuel/increases range but reduces the wear and tear to extend the service life interval, saving operators time and money.
Advanced Sensors
We’ve embedded vibration sensors which are a good indication of whether you have a problem. Data from the vibration sensors gives us new opportunities in the testing phase of our vessels and we’re beginning to learn what type of input from sensors we want and what we should be reacting to.
Electric and Hybrid Capabilities
The next phase we’re working on is to replace one or both of the twin-engine inputs with electric motors, giving you a lot of powertrain flexibility because they can be fed by gensets (generator sets). Gensets may run on conventional diesel, but ours are certified for Hydrotreated Vegetable Oil (HVO), which could reduce carbon footprint by 90-95% depending on the HVO specification. We’re also working on integrating battery packs and fuel cells as additional power sources.
What are some of the challenges in designing electric marine vessels?
Depending on the vessel and use case, there’s a wide range of marine power requirements. For instance, a ferry vessel is predictable going from point A to point B back and forth, and battery power with fast charging is a potential sustainable solution. However, for a super leisure yacht, the use is unpredictable and you’d likely add flexible backup power sources such as fuel cells or backup generators.
Another challenge for fully electric vessels is that it’s typically around a hundred times more energy to push a boat through water than to roll a vehicle down the road. When you translate that into battery power, today’s battery power density isn’t enough to accommodate a full day on the water… yet. That’s quickly changing, and Volvo Penta is continuously building prototypes to experiment with the boundaries of today’s electric technology.
Despite the challenges, there are early adopters. For instance, offshore wind farms are concerned with their carbon footprint, so they’re eager to use electric powertrains, and tourism operators benefit from an electric powertrain that doesn’t disturb nature as much as a loud and shaky combustion engine.
Anything else to add?
The marine industry is interesting because it’s a low-volume, high-complexity industry that integrates many technologies, tailored for small populations with very specific needs.
When it comes to making the electric switch, it’s often a very rewarding collaboration between us, the design engineers, operators, and owners to find the best renewable solution for their application.
