Volvo Penta helps power the World’s first fleet of commercial autonomous exploration vessels




The maritime and scientific community have set themselves the ambitious target to map the entire ocean floor by 2030. Volvo Penta is doing its part to meet this goal – by helping to power a novel fleet of unmanned surface robots for subsea exploration.

Volvo Penta and Danfoss Editron have been selected to be part of a truly unique venture. The companies have been commissioned – above numerous other manufacturers – by Grovfjord Mek. Verksted (GMV) shipyard, to power the world’s first fleet of autonomous robot exploration vessels for commercial use. The seafloor analysis and oceanography company – Ocean Infinity – has invested in the ‘Armanda’ fleet of super-advanced unmanned vessels. The fleet will be made up of two sizes of vessels both of which will be 100% diesel-electric.

“Volvo Penta is delighted to be part of this groundbreaking project in cooperation with Danfoss Editron,” says Johan Inden, Head of the Marine Segment at Volvo Penta. “Together, we will deliver an optimized power solution – to the autonomous Armada fleet – designed for ultimate performance while reducing the environmental footprint. ”

“This is the first time that a commercial autonomous fleet is being developed, rather than just being a prototype,” explains Erno Tenhunen, Marine Director at Danfoss Editron. “We are very proud to have been chosen for powering it.”

Fully hybrid-electric power

These fully hybrid-electric vessels will be powered by Volvo Penta DC gensets and Danfoss DC grid controls. Danfoss will provide the energy management system and propulsion control for each vessel while the engines behind the power management will be variable speed gensets delivered by Volvo Penta.

The Volvo Penta D8 MH variable-speed engine will power the marine generator sets on board. This all-new D8 engine is a perfect match for the autonomous vessels due to its compact size and high power to weight ratio. Additionally, the engine’s low fuel consumption plays a big role in the significant CO2 reduction.

Perfectly in sync

One of the key objectives for a project like this is to deliver a reliable and efficient product. These vessels will be in the open ocean far away from land and maintenance providers. Ocean Infinity needs to know that its vessels are meeting peak performance.

Danfoss Editron, Volvo Penta, and Grovfjord are working in close collaboration to enable the Danfoss control system to optimize the use of the Volvo Penta D8 engine for the most efficient power/consumption performance and consequently an optimal environmental footprint. The engine, the generator, and the control system work in perfect harmony.

The generator set is also designed around maximum weight savings and the corporation with The Volvo Penta genset outlet Powerhouse has added an additional element of flexibility to ensure the delivery of the power package suitable for the vessel.


This fleet of autonomous vessels will provide new opportunities for deep-sea exploration. Each vessel will be able to launch separate remotely operated underwater vehicles (ROVs). These unmanned submarine-like ROVs will reach depths of up to 6000m and carry out surveys on pipeline routes as well as collect vital seismic data. Currently, ROVs need to be tethered to manned research vessels – with some operation costs in the millions! This new fleet of autonomous surface vessels will mean that ROVs can be operated – without a nearby host vessel – via satellites from onshore facilities in the U.S. state of Texas and the U.K. city of Southampton.

This streamlined approach to commercial deep-sea exploration will help deliver efficient operations, cut costs significantly, and reduce the harmful environmental impact sometimes associated with traditional operations.

“This contract is a fantastic opportunity for us,” says GMV’s CEO Bård Meek-Hansen. “The fact that a world-leading company – like Ocean Infinity– would choose to partner with us is a great honor, and it highlights that our focus, on design and technology development, in recent years has been right. We look forward to cooperating with Ocean Infinity, Danfoss Editron, and Volvo Penta for the development and construction of these vessels.”

The first four vessels in the Armada fleet are due to be delivered to Ocean Infinity in 2021, with the remaining robots completed in the next months.

Proportional valves with linear motors in the medical industry




The Precision Fluidics Division of Parker Hannifin, the global leader in motion and control technologies, announced the release of their new Parker LM-Pro linear motor proportional valve targeted at the respiratory and anaesthesia markets.

“The Parker LM-Pro miniature proportional valve utilizes a patent pending linear motor actuation technology to enable flow up to 540 slpm in a very compact and energy efficient package, while providing an unparalleled, controllable range to allow for use across multiple respiratory applications,” says Beth Young, division marketing manager at Parker Precision Fluidics.

A critical feature of the LM-Pro valve is the valve’s linear motor actuation technology that provides exceptional resolution over a longer stroke and lower power consumption than traditional solenoid or voice coil actuation designs. With a linear controllable flow range from 0.5 to 540 slpm, pressure capability up to 100 psi (6.9 bar), and typical power consumption of less than 2 Watts, the LM-Pro valve enables very precise flow control throughout the full performance range of the valve. The LM-Pro valve allows for simple, closed loop feedback, giving the customer precise pressure or flow control. This ensures accurate and safe delivery of precise gases to patients, from neonates to adults. Typical applications will have power usage of less than 2 Watts, giving the customer longer battery life or ability to use a smaller battery to save size and weight. Typical hysteresis of <10% (full scale), coupled with a fast response time of <20 msec (full cycle), give the customer the ultimate in low and high flow rate and precision control proportional valve performance.

The Parker LM-Pro is a true, one-size-fits-all, proportional valve. Its unrivalled performance capability combined with the simplicity of a face mounted/ported design make the LM-Pro valve an ideal solution for varied applications with dynamic flow control needs. “It is ideal for customers who are trying to increase performance while continuing to decrease the footprint of their products,” says Paul Nierman, division engineering manager at Parker Precision Fluidics.

As systems become smaller and more portable, power concerns and accurate flow control at both the high and low ends of the spectrum are vital. The Parker LM-Pro linear motor proportional valve is a great example of the portfolio of products at the Precision Fluidics Division of Parker Hannifin that lead the market in miniature, low power, light weight, high performance fluidic products.

Ziehl-Abegg’s elevator division reaches an all-time high




South-East Asia and Europe deliver a 12 percent increase for the Hohenlohe motor manufacturer

The elevator drives division at Ziehl-Abegg has been running at an all-time high for the past two months. “We have never had such a high order intake in the elevator sector,” says CEO Peter Fenkl. The orders are coming mainly from Europe and Southeast Asia.

2019 had already been a record-breaking year for the elevator specialists at the electric motor manufacturer Ziehl-Abegg: in the final count, it posted sales of more than 72 million euros. In the current year, business in the elevator division has continued at the same record level as in the previous year. “However, the development in order intake since March is far exceeding our expectations,” says CEO Fenkl. “We are currently 12 percent up on the previous year!”

Ziehl-Abegg is benefitting from being located in Germany. In contrast to Southern Europe, where in Italy and Spain many companies are closed, production in Southern Germany is in full swing. Even in the current corona crisis, the supply chain is working and supplies to production are secured, with even kit manufacturers in Spain ordering elevator motors and control units from Ziehl-Abegg in Hohenlohe. “Many of our customers’ finished products end up all over Europe, including England,” explains Sales Manager Dieter Rieger. It’s a similar picture in South-East Asia: the closure of regional companies has created a vacuum for elevator manufacturers, the result is that they are now buying components on the global market – for example, from the German manufacturer Ziehl-Abegg. “A large proportion of the volume is coming from new construction projects,” says Rieger.

The motor division at Ziehl-Abegg is the second largest area of business in the Group. Worldwide, Ziehl-Abegg employs 4,300 people, spread over the areas of ventilation, control and drive technology plus automotive. “It’s during times of crisis in particular that the strength of our broadly-based portfolio becomes evident”, underlines CEO Fenkl.
