Ever since the global financial meltdown of 2008 briefly crippled the world leisure boat market, Volvo Penta adopted a strategy to increase its commercial market share with its family of innovative propulsion systems and controls. Last week off the west coast of Sweden, Maritime Reporter & Engineering News got up close and personal with the new D8 diesel and IPS15 pod, as well as the full range of command and control products courtesy of a day of test drives at Krossholmen, Volvo Penta’s Global Marine Testing Center.

In the middle of a financial storm such as the one that swept the globe in 2008/2009 it is not easy to see a ‘silver lining.’ However Stefan Carlsson, Volvo Penta’s Marine Diesel segment head said that the dramatic drop in marine leisure business in 2009 set the company in a new strategic direction, determined to maximize efficiencies while diversifying its business into the commercial sector. Cracking into the rigorous commercial market is easier said than done, but with perseverance and a steady expansion of its product and service, Volvo Penta now offers a compelling argument as a one-stop-shop for a variety of workboat sectors.


New Product: The D8 Diesel Engine

Well-engineered products with a solid support infrastructure is mandatory in the workboat sector, and last week Volvo Penta effectively broadened it product range to compete more efficiently. The company introduced the D8 engine – which will replace the D9 – built to U.S. Tier III and IMO II specification and available in 450, 510 and 550 hp models.

The 8-liter engine expands the offering between the D6 and D11 models, for applications that require low weight with high power suited for propeller, waterjet and Volvo Penta IPS applications. The new engine has been designed for use in planing craft, and commercial uses include fast patrols, coast guard and rescue launches, police and ambulance boats, water-taxis and high-speed passenger ferries, fishing boats, and offshore support vessels.

While the D8 is new to the marine market, it is a well-proven platform which has been manufactured since 2013 serving the truck, buss and off-road industrial market. Krossholmen proves an ample testing ground for anything on the water, as Volvo Penta runs a diverse test boat fleet of more than three dozen boats, ranging in size to 70 feet in length.

The D8 is an in-line six-cylinder engine with a cylinder capacity of 7.7 liters, twin-entry turbo and sea-water cooled heat exchanger, a heat exchanger manufactured of composite material to eliminate corrosion. The engine has a common rail system (Denso) working up to 2000 bars. The injection is electronically controlled, and pre-, main, and post-injection are essential aspects for the engine’s power, torque, fuel efficiency, low noise and emission levels. 

“The high power-to-weight ratio together with the new common rail injection system where the nozzle has been optimized, together with a piston bowl of re-entry type, will provide excellent fuel efficiency,” said Anna Pettersson, chief project manager for Volvo Penta’s marine engines. 

Volvo Penta has developed three power outputs for the D8 inboard range – of 450, 510 and 550hp. They are designed to conform to the US EPA Tier 3 emissions standards, as well as IMO II and EU IWW. EPA certificates are expected in January 2017.  Power ratings will be set at R3 (for 450hp), and R4 for both 510 and 550hp. The IPS system, engine, drive and propellers are expected to be approved by DNV-GL. The inboard engine will also require certificates, which will be applied for from the classification societies: DNV-GL, RINA, LR, China CSS, RS and the Indian Register of Shipping (IRS). The engine will be ready for delivery in June 2017.


Meet the IPS15

Volvo Penta’s Inboard Performance System (IPS) is the showcase of the company’s innovations in marine engineering, and last week the IPS family added a fourth member, the IPS15, which has been developed and optimized to fit the D8 engines for the commercial market. Since its inception in 2005, Volvo Penta has continuously worked to develop its IPS pods to offer an integrated propulsion package with greater performance, fuel efficiency, maneuverability and comfort.

“It is all about propulsion efficiency and productivity for the yards, designers and operators. This is a fantastic move for us and our customers,” says Jakob Ursby, strategy manager for Volvo Penta’s Marine Commercial sector. 

The IPS design features forward-facing twin counter-rotating propellers which are mounted beneath the hull. As the propellers operate in undisturbed water, they cause less drag, which Volvo Penta claims improves performance and fuel consumption by up to 30% compared to traditional inboard engines. Features of the type approved IPS15 package include:

•Improved materials for heavy-duty commercial use.

•Reduced ratio of weight and hydrodynamic resistance.

•Reduced ratio of hull insert size.

•Optimized backpressure with 6-inch exhaust system.

•A new propeller series (N) custom fit for the system.

•Improved maneuverability with increased steering angle at low speed.


Integrated Solutions

Central to Volvo Penta’s commercial marine market push is the offer of a comprehensive, integrated solution. While the engines and IPS are central components, the entire package includes a family of intuitive and integrated controls, encompassing a joystick option, docking mode and dynamic positioning; it includes Humphree trim and stabilization products, as Volvo Penta recently took a majority stake (80%) in the iconic company; and it include the ‘glass cockpit’ solution, which ties together critical operational information in one neat, customizable package.

Installation of the IPS with 8-liter engines can be made for twin and triple configurations. For triple installations, one pod can also be disengaged and the engine can be used in PTO mode – for example, in powering a water canon on fire rescue boats - while still keeping maneuverability on the other two. The new package has three power settings:

D8 IPS600

D8 IPS650

D8 IPS700

The package has been designed to conform to US EPA Tier 3 emissions. The D8 IPS models will be available for delivery in May 2017.

Scania Sees Strong ’15 in North America

Mikael Lindner, President, Scania North America, sat with to reflect on the current and future direction of the power company’s marine business in North America.

As the marine market follows in step with other transport and industrial sectors to literally clean up its collective act, marine power providers are at the tip of the spear in the quest to make commercial marine operations more environmentally benign and in line with new regulations on emissions.
Broad-based global corporate power companies such as Scania boast an advantage in this regard, able to apply lessons learned from other industries and leverage a well-funded R&D budget to ensure its lines are modern, capable and ready.

“There is a buzz regarding Tier 4, even though it is still two to three years away,” said Lindner.  “I think we have a really good plan, and it is not rocket science by any means; you will likely need to have after-treatment in some form. As Scania is a global manufacturer of power for trucks, buses and many different markets, we have all of these technologies within our own company (to meet the strictest new emission regulations).”

Scania has been a face in the North American workboat market for several years now, entering a large and mature market with a history of providing power solutions across multiple industries globally. With a long-term plan to penetrate one of the world’s largest workboat markets, Scania’s patience is starting to pay dividends with steady growth in new installations and re-powers.

“Looking at North America, 2014 should be similar to 2013 in that we are on a constant growth pattern; 2013 was a record year for us, 2014 should be close and things look promising for 2015,” said Lindner. “Five or six year ago we started with our plan, and we’re starting to see this bear fruit now.”

According to Lindner, the success of the company in North America starts and ends with the quality of its engine family.

“We have a very solid line-up of products, a very solid platform, that we continuously work on developing further in terms of power and performance,” said Lindner.  We concluded the introduction of the current platform two to three years ago with the addition of the new 16 and we introduced our Tier III engine line-up last year. Many customers have installed this platform now, and they are proving themselves: that’s a big driver, the product is installed and proven.

“With our 16 you get power, performance and durability in a comparatively smaller and lighter package,” said Lindner. “The challenge is convincing the customer that they don’t need that much iron to power their vessel.”

This year was significant for Scania in North America as it continued to strengthen its dealership network and entered some new markets in Canada. “Canada, thanks to our distribution, is working well for us,” said Lindner.

Looking forward Lindner said a main focus now is the emission standards coming for ECA areas and IMO III. “After that, Tier 4 is the next big challenge,” said Lindner. “Without saying too much, the IMO III solution most likely will be a solution for Tier 4.”
