Like other modes of transport, the shipping sector is reaching a point of no return. Changes must come, and we are already in the forefront of this process. Through our innovations, we will take on the challenge of combining efficiency and reliability with corporate and environmental responsibility. We have been pioneers in safety and sustainability in tanker shipping for many decades and we intend to keep our pole position.

Terntank Hybrid Solution®

By adding electrical power to the vessel, Terntank is taking a huge step towards clean shipping. These revolutionary tankers will completely change the way we operate.

The HYBRID SOLUTION® combines an onshore power supply with the conventional engines, enabling us to run on 100% electricity when handling cargo in ports. The cutting-edge Battery Pack stores electrical energy and provides clean power to manoeuvre to and from port without any extra generators. The hybrid solution gives the twin advantages of reducing emissions near land as well as radically decreasing the noise generated by the ship’s engines.

Estimated environmental savings per year and per ship are in the magnitude of 456 metric tons of CO2. An increasing number of ports are ready to invest in onshore power supplies that can provide vessels with the necessary charging from the quayside. By only using energy that comes from renewable resources, the environmental benefits become even greater.

The hybrid system includes

  • Energy storage system
  • Shore power connection
  • DC Link system
  • Frequency-controlled cargo and ballast pump
  • 100% Biofuel compatible

Hybrid vessels equipped with the new system displaying the Hybrid logo on their LNG/LGB tanks.


Our environmental awareness has taken Terntank operations into another league with the application of the Just-In-Time management. Over the last four years, Terntank has implemented the Just-In-Time concept in close collaboration with its customers and in doing so has optimized the voyages and reduced emissions.

How it works

Just-In-Time is an operational method that aims to minimize emissions – in our case, to optimize voyages between ports and to reduce the time spent at anchor. This is achieved by constantly adjusting the vessel’s speed to meet its agreed time of arrival and utilising slow steaming to allow us to send a Virtual NOR, moving directly into port instead of dropping anchor and waiting to berth. This is a win-win situation for all parties involved. To ensure that we comply with the BIMCO clause on slow steaming and to track real-time savings, we have installed technology that gives the exact savings of the JIT operation in an emissions report.


We are continuously developing sustainable shipping. One major step was our decision to replace traditional fuel oil by LNG (Liquid Natural Gas). This changeover to the far cleaner fuel of LNG on our Avic series brought about huge improvements for the environment: CO2 emissions reduced by 20%, SOx by 99%, NOx by 97% and particles by 99%. However, LNG is still a fossil fuel and we had even higher ambitions. Our LNG/Avic vessels are now able to operate on 100% biofuels. 

LBG (Liquid Biogas) is essentially a fossil-free version of LNG made from renewable resources. We carried out our first trials with a biofuel blend in 2018 and they were entirely successful, preparing us for the next step towards fossil-free operations.

We believe that working in close cooperation between environmentally responsible companies is the start of a new green era in shipping.

The LBG that we use is made from organic waste and residues and is certified by the ISCC (International Sustainability & Carbon Certification).

LNG is just the first step. We aim to gradually increase the proportion of LBG since the combustion technology and infrastructure works equally well for both gases.


Safety is one of the most important aspects of tanker shipping and many improvements have been made during the history of Terntank. We have remained far ahead of legislation in this area by continuously striving to make our ships better and safer right from the start, meaning at the design stage.

Terntank is committed to the UN sustainable development goals and our CSR practice is well-rooted in the company’s values. We aim to operate and manage ships with zero spills, zero incidents, and minimize pollution to the air. Terntank considers economic, social, and environmental impact in every operation. Acting sustainably, and creating added value for our customers and shareholders, as well as for the surrounding society, are the core of Terntank’s business

Terntank takes pride in being a pioneer in shipping and to enable this, strict guidelines are needed. Terntank’s different guidelines and policies guide all the operations from company level to individual vessels and personnel. Terntank has established HSEQ (health, safety, environment, and quality) policies. Soon you will be able to read our commitment that lay as the foundation of the company’s social responsibility here on this page.
