Kongsberg clinches Tärntank hybrid equipment contract

The series of 15,000 dwt chemical tankers are currently under construction at China Merchant Jinling Shipyard in Yangzhou.

The last five ships in the series will have Ventofoil suction sails from Netherlands-based Econowind, projected to cut emissions by up to 19%.

As hybrids, the tankers will be capable of running on diesel, biofuel or methanol, and will have the Danish company’s proprietary battery-powered Hybrid Solution.  

The vessels will also have Kongsberg’s Promas system, an integrated propulsion and manoeuvring setup. It comprises a propeller, Costa bulb, hub cap, and twisted rudder which, in combination, improves water flow, increasing energy efficiency, propulsive efficiency, and manoeuvrability.  

Kongsberg Maritime’s Rune Ekornesvåg, Sales Director, Ship Design, commented: “This latest contract for our fuel-efficient and low-emission tanker design reaffirms the commitment of forward-thinking shipowners to integrating sustainable technologies into their fleets. The vessels will feature our Promas propulsion system, which delivers fuel savings of over 6% compared to other systems. Additionally, the ships will utilise battery-powered hybrid propulsion, enhancing operational flexibility and minimising environmental impact.”

The design for the latest tankers in the series, including suction sail wind propulsion, won the Nor-Shipping Next Generation Ship Award last year. The first vessel is due for delivery in 2025.
