Volvo Penta sea trials of new IMO Tier III at Seawork


Visitors to the 2018 Seawork (Southampton, July 3rd to 5th) had the chance to test Volvo Penta’s 13-litre IMO Tier III solution complemented by its latest state-of-the-art Inboard Performance System (IPS) propulsion package.

A test boat fitted with a Volvo Penta D13-IPS900 (700 hp) package and selective catalytic reduction (SCR) exhaust after-treatment system was available for sea trials by customers at Seawork commercial marine and workboat exhibition and conference, in Southampton, UK. The engine and latest IPS propulsion model – which runs at 700 hp but gives an enhanced performance to the equivalent of a 900 hp inboard shaft installation– were complemented by a compact and flexible SCR.

According to Gerard Törneman, sales project manager for Volvo Penta’s Marine Commercial segment, this was a unique opportunity for customers to appreciate the achievements made by Volvo Penta in advancing propulsion technology and reducing emissions.

While International Maritime Organization (IMO) Tier III standards are due to come into force in 2021 for the Baltic and the North Sea, Volvo Penta gave customers the chance to fulfil their obligations more than two years early, as the company’s engine solutions become available in 2018. The solutions are optimized for marine applications and will be available for inboard engines, IPS, auxiliary engines and complete marine gensets.

“A lot of customers are requesting our IMO Tier III products now as they want to achieve lower emissions before the legislation comes into force,” said Törneman. “Some of them are also fulfilling local initiatives and are able to access special grants by adopting the standards now. Customers that are already using one of our IMO Tier III solutions say that they appreciate it as it’s simple to install while also meeting the required levels of performance. This is the hallmark of Volvo Penta.”

Volvo Penta IPS is a unique, type-approved system that improves productivity and performance with exceptional manoeuvrability, thanks to the individually steerable pods that feature forward-facing, twin counter-rotating propellers that lie under the hull. The design also results in a reduction of fuel consumption and carbon dioxide emissions by 30 per cent – compared to inboard shaft engines – and an increase in onboard comfort due to reduced noise and vibration.

“Volvo Penta is the first company in the market to deliver a complete and integrated propulsion system, from prop to helm, now including an SCR exhaust after-treatment system – all from one supplier, for IMO Tier III,” said Thomas Lantz, product planning manager for Volvo Penta’s Marine Commercial segment.

Volvo Penta’s D13-IPS900 is fitted with selective catalytic reduction (SCR) for IMO Tier III regulations.

“Our IMO Tier III solution has minimized piping and includes a silencer, and with the unique properties of IPS, we have produced a system that is efficient and robust, that can withstand the toughest of marine conditions. Our technology means that we are reducing both NOx and CO² in one compact package”

Volvo Penta’s D13 units for IMO Tier III are available to order now for delivery during the last quarter of 2018.
