ABB Turbocharging, at the Marintec 2017 conference and exhibition in China, unveiled the new Flexible integrated Turbocharging System for Two-Stroke Engines (FiTS2), intended to offer greater flexibility and lower fuel consumption to vessels with two-stroke main propulsion.
The company explains that the system offers significant long-term economic benefits for vessel operators and charterers with potential for fuel savings of up to three percent, depending on load profile.
ABB Turbocharging notes that NOx emissions from engines fitted with FiTS2 will also remain within IMO Tier II limits, and additional abatement technologies, such as SCR or EGR, can be used without greatly affecting the system or its fuel-saving benefits.
"From an operator's or charterer's perspective, FiTS2 efficiency benefits will enable major cost reductions," said Joachim Bremer, Head of Product Line Low-Speed at ABB Turbocharging.

"Considering for example a typical current fuel bill of 3 to 4 MUSD per year for very large crude oil carriers, FiTS2 has potential to provide fuel cost savings of up to 100,000 USD per year, compared with levels typically achievable using conventional turbocharging systems. Big savings are also possible for other vessel types, e.g. for container vessels and can amount to 1 MUSD or more over 10 years. The payback of initial costs can be less than two years, making the FiTS2 solution very attractive."
The new system was developed in collaboration with Winterthur Gas & Diesel Ltd. (WinGD), which has developed a special tuning for FiTS2.
