Höegh Autoliners upgrades propulsion, orders bridge tech for newbuilds

Höegh Autoliners has ordered propulsion systems from Kongsberg Maritime for 10 pure car and truck carriers (PCTCs) to reduce fuel consumption and emissions.

Kongsberg Maritime is also contracted to deliver electronic and propulsion components for Höegh’s new Aurora-class vessels, including K-Bridge navigation systems, K-IMS units for emissions monitoring and reporting, K-chief engine controls and Promas propulsion modules.

For the existing PCTCs, the Norwegian group will supply Promas Lite propulsion systems, which were developed specifically for retrofitting and improving propulsion efficiency. Promas Lite integrates the fixed pitch propeller, hub cap, bulb and rudder into one propulsive unit, increasing efficiency and generating fuel savings.

Kongsberg expects the propulsion upgrades for Höegh Autoliners’ DSME-class PCTCs to achieve fuel savings of at least 6.5%, according to detailed hydrodynamic studies conducted at its Hydrodynamic Research Centre. This prediction has been validated by full-scale measurements taken from two vessels already refitted with the Promas Lite system, confirming the anticipated efficiency gains.

“Höegh Autoliners is dedicated to reducing its environmental footprint," said Höegh Autoliners chief operating officer Sebjørn Dahl.

"An important factor of this is to consistently strive to improve our vessel performance by adopting the most energy-efficient solutions from highly qualified and dedicated suppliers. Our partners at Kongsberg Maritime are helping us drive this vision forward with the Promas Lite propulsion system."
