Ilivileq ready to trawl the Arctic

0

The Kongsberg Maritime-designed freezer trawler known as ‘Ilivileq’ has entered service in Arctic waters.

Ilivileq uses a hybrid-propulsion system which Kongsberg says allows the captain to select operational modes from the bridge panel and monitor the fuel consumption in each mode.

The hybrid system runs the engine and propeller at variable rpm (combinator mode) following what is claimed to be the optimal propeller curve. The unit reduces fuel consumption by reducing the pitch loss that fixed rpm propulsion systems have, especially when operating in modes requiring low load on the propeller. In combinator mode, the hybrid shaft generator works with an AFE drive that secures constant fixed frequency to main switchboard and suppliers.

Bard Bjorlow, executive vice president global sales and marketing, Kongsberg Maritime, explained that Ilivileq’s emissions are reduced with nitrogen-oxide reduction technology from selective catalytic reduction.
