The Dutch Shipyard Ferus Smit will deliver the 89 by 13.35 m, 1B ice class, 206k ft3 capacity freighters starting September 2024.

The energy from the battery packs will be used for peak shaving and power smoothening, reducing the reliance on auxiliary engines for electricity generation - or even turning them off at anchor.

The Lake Vanern Maxes will also be equipped with connectors for drawing electricity from the shore, thus shutting off all engines to lower in-port emissions, likewise cancelling noise pollution.

"At the heart of the Lake Vanern Max lies a propulsion system designed for superior performance with a large diameter propeller operating within a nozzle. This configuration delivers increased thrust, particularly at lower speeds, resulting in reduced power demand during challenging seaways like Göta Älv [the Göta River] and icebreaking operations. As a result, the installed main engine power can be minimised while maintaining optimal performance and meeting the stringent requirements of Ice Class 1B. With the combinator mode and variable propeller, the fully automatic system constantly selects the optimal load point, maximising propeller efficiency and reducing fuel consumption," the shipping company shared in a press release.

Other measures to reduce electrical consumption aboard the Lake Vanern Maxes will be implemented, too, such as harnessing excess energy with cooling water heat exchangers in the main and auxiliary engines.

"We are proud to lead the way in maritime innovation by introducing the Lake Vanern Max, a vessel that sets a new standard in efficiency, performance, and sustainability. These vessels exemplify our unwavering commitment to sustainable shipping and pave the way for a greener and more prosperous future," Henrik Källsson, Deputy Managing Director at Erik Thun Group, commented.
