Hybrid Solution

Adding Electrifying power to our Fleet/vessels and taking the step into the future of clean shipping. These groundbreaking tankers will revolutionize the way we run tankers.

The hybrid solution combines the shore power which enables us to run on 100% in the port handling cargo and with the cutting edge Battey Pack that stores the energy and gives us the power to maneuver to and from the port (without extra generators). With the Hybrid Solution upgrade, we have the ability to reduce our land near emissions and reduce the noise generated from the ship.

The Hybrid Solution vessels that are equipped with this new system has the new Hybrid logo on their LNG/LGB tanks.

In early calculations, we are saving 145 000 liters of diesel/year/ship since the project started more and more ports are aiming to electrify their ports and provide the vessels with green energy which makes our savings even larger.

The hybrid system contains:

  • Energy Storage System solution
  • Shaft Generator and Motor solution
  • Main engine fuel optimization
  • Frequency controlled cargo- and ballast pump solution
  • Bow thruster drive
  • On-shore power system for power-supply while at berth
  • We want to innovate the way we see tankers

    Just in time

    We at Terntank have taken the environmentally operation to the next level, just in time. Over the last three years, Terntank has with close collaboration together with customers implementing the Just in time concept and saved between 275-300 mt of bunkers equals to 945 mt of CO2.

    Just in time aims to optimize the voyage and minimize the emissions that are associated with the time that the ship spending at anchorage awaiting berth.

    How it Works
    The Just in time concept is an operational concept that aims to optimize the journey between ports and reduce the time spent at anchor. This is accomplished by adjusting the vessel speed aka slow slows-steaming, to meet their time of arrival. By allowing us to send a “Virtual NOR” and slow slow-steam directly into port instead of dropping anchor and await to birth. “This is a win-win.” To meet the BIMCO Clause and to track the real-time savings we have installed technology that gives you the exact savings of the JIT operation in a report.

    Green bill of laiden
    How do we ensure that we reduce emissions when we are just in time, Terntank – Green bill of laiden. This is a report that we provide that tracks your emissions savings for each JIT trip.

    If you are interested to learn more about this and how it benefits you, then please reach out to us and we will explain how.

    LNG & LBG Propulsion

    When we built to shift fuel from gas oil to the clean LNG on our newbuilding’s we reduce the co2 emissions with 20% Sox 99% NOx 97% and the particles with 99% emissions by 95%. With the Biogas, we are taking it one step closer to a fossil-free operation!

    Liquide Biogas is the fossil-free variation of LNG and we did our first test run on a biofuel back in 2018, the sea trial went perfect! The gas is now ready to take the next step.

    Today our Tern Ocean that is time-charted by Preem is running on a 10% biogas blend. Liquids Bio Gas or as is called LBG can be used 100% or as and blend in fuel. It’s produced in several different ways and. Our vessels are prepared to run on the biogas.

    Our biogas is certified by the ISCC – International Sustainability & Carbon Certification. Back in 2018, we did our first voyage on an LBG blend in the port of Gothenburg. Our journey towards fossil-free operations. It’s a small step for Terntank, a big leap for shipping.

    Sustainability is and has been a key part of our core business

    LNG är första steget. Att gradvis öka mängden biogas är fullt möjligt då teknik och infrastruktur fungerar lika bra för båda gaserna.


    Safety is one of the most central elements in tanker shipping and much has happened during the history of Terntank. By continuously strive to make the ships better and safer we have stayed way ahead of legislators. Tärntank Rederi AB took delivery of its first double hull tanker as early as in 1974 and this was decades before it became mandatory.

    In 2011, Tärntank launched the Tärntank Environmental Shipping project in collaboration with the oil company Preem. The tanker Tarnvag has been equipped with the Catamiser on the main engine and all auxiliary motors.

    Being a family company with its roots on an island, established by and still operated by people with seagoing experience and professional competence from shipboard operations, Tärntank has high ambitions to make the working and living conditions for its seafarers the best achievable. Modern society depends on reliable transportation of oil, oil products, and chemicals but living close to the sea has made the management of Terntank highly aware of the sensitivity of the marine environment.

    We even had double hull decades before it became mandatory.

    Switching to an LNG working environment changed the air quality and even the smell became better in the tankers.

    The sustainable cargo that we carry

    Our tankers are designed to meet the fuels of the future. Today there is a big pallet of different fuels. When we are looking into the future we see a shift in the usage of biofuels.
