Logistics company Toll Shipping has ordered hybrid scrubbers from Yara Marine Technologies for two ro-ro vessels to be built at Jinling Shipyard in Nanjing.

The vessels, the first of which will be delivered next year, will be equipped with two 10.2MW MAN B&W engines that will each be connected to one exhaust gas cleaning system (EGCS).

Both vessels will operate on the environmentally sensitive Australian coast and the scrubbers are designed to minimise impact, including membrane technology to reduce sludge transportation and frequency converters on pumps to lower energy consumption. The scrubbers use magnesium oxide as a cleaning agent, which is both cheaper and safer for crew to handle than caustic soda.

“For Toll it is important that our two new vessels not only provide us with 40% more capacity, but also allows us to improve safety outcomes for our people and deliver a better outcome for the environment,” said Tony Stewart, group general manager, Toll Shipping.
