The time for biofuels is now

Uni-Tankers has the access and knowledge to take advantage of the measurable decarbonization benefits of biofuels

Following a successful biofuel trial in 2023, Uni-Tankers can now offer customers the option of powering their cargo’s voyage with biofuels that emit less greenhouse gases (GHG) on a life-cycle basis compared to traditional fossil fuels.

The test on M/T Alsia Swan showed that using a 30% biofuel blend (B30) resulted in up to 30% less CO2 emissions compared to a standard fossil fuel-based LSMGO (Low Sulphur Marine Gas Oil).

Known in the industry as a ‘drop-in’ fuel, biofuels can be mixed with similar versions of fossil fuels for use in existing engines. This means they are an ideal transitional fuel for short-term gains and, combined with energy efficiency measures, they will be vital for keeping vessels compliant with International Maritime Organization (IMO) and European Union (EU) decarbonization regulations.

“As environmental legislation and regulations become increasingly tight, we expect the demand for alternative fuels will increase. Thanks to our sister company Bunker Holding, our customers can choose biofuel blends to power their voyages with UniTankers,”

Kristian Larsen

Technical Director, Uni-Tankers

Testing leads to understanding

In 2023, Uni-Tankers and KPI OceanConnect — a subsidiary of Bunker Holding — successfully completed a two-day trial of the latter’s B30 biofuel blend, providing a thorough picture of this particular fuel’s performance throughout a voyage. A thirdparty team from FORCE Technology compared the results of the B30 blend with a standard LSMGO under the same engine loads (25%, 50%, 75%, and 100% power). In addition to reduced CO2 emissions of 30%, their results also showed a 42% reduction in particulate matter and an 18% reduction in carbon monoxide emissions.
Due to the central role biofuels will play in our decarbonization journey, we will continue testing to better understand alternative fuels and their impact (e.g. how they should be handled, how they affect engines, how much they reduce lifecycle GHG emissions).

EU legislation will boost alternative fuel transition

Due to the immediate useability of biofuels, they will play a vital short-term role in decarbonizing Uni-Tankers’ fleet. And soon,they won’t be an optional extra.

With the European Union’s FuelEU Maritime regulation set to come into effect from January 1, 2025, all vessels over 5,000 GT (gross tonnage) that call into European ports will be required to reduce the GHG intensity of the maritime fuels they have on board by 2%, which will rise to 6% by 2030 and intensify further towards 80% in 2050.

With global biofuel production not expected to match growing demand from various industries over the coming decades, Uni Tankers will continue to investigate and adopt other alternative fuel options to achieve its decarbonization targets.

Energy saving tech vital to 2030 decarbonization goals

Uni-Tankers’ ongoing roll-out of fuel efficiency technologies across our owned fleet has reduced our fuel consumption per vessel

Uni-Tankers’ commitment to decarbonization is having a clear and measurable impact, with fuel-saving technologies contributing to a more efficient fleet. In 2022/23, Uni-Tankers’ emissions from fuel consumption increased by 6%, but this is mainly due to a 9% increase in the number of vessels in operation compared to 2021/22. With fuel-saving technologies now installed on 11 of 16 owned vessels (up from 7 in 2021-22), we achieved fuel savings of 8-15% per vessel for those that have the technology installed. (See page 3 of Uni-Tankers’ 2022/23 ESG Report)

Initiatives duing the previous period

As of the conclusion of the 2022/23 fiscal year, Uni-Tankers has made significant strides in enhancing the sustainability of its fleet. Notably, fuel-saving technologies have been successfully implemented on 11 out of 16 owned vessels, a notable increase from the 7 vessels in the preceding fiscal year (2021/22). This proactive effort has resulted in substantial fuel savings ranging from 8% to 15%.

In a bid to explore innovative approaches, a noteworthy initiative in 2023 involved the application of a high-performance nano-modified epoxy coating to the M/T Fenno Swan. Although this application is still undergoing testing, preliminary results are promising, indicating potential fuel savings through friction reduction.

Furthermore, Uni-Tankers, in collaboration with the Bunker Holding Group, conducted B30 biofuel testing on its vessels during 2023. This initiative aligns with a broader commitment to environmental responsibility. Concurrently, plans have been set in motion for the Group’s headquarters in Denmark to transition from on-site gas heating to district heating by 2025, contributing to a reduction in emissions from onshore activities.

The results from the B30 biofuel testing revealed a substantial reduction of particle emissions by up to 42% compared to traditional LSMGO fuel. While no significant changes in NOx emissions were observed, there was a noteworthy 18% decrease in carbon monoxide emissions. These initiatives collectively underscore Uni-Tankers’ dedication to advancing sustainable practices within the maritime industry as we acknowledge that decarbonization is a key element in our formula for a better future.

Overall, this positively contributed to Uni-Tankers reducing its Energy Efficiency Operational Indicator (EEOI) rating, which is the International Maritime Organization’s (IMO) method for measuring the efficiency of vessels. The EEOI measures how efficiently vessels carry cargo in CO2 emitted per quantity carried and distance sailed. From 2021/22 to 2022/23, as an average across Uni-Tankers’ operated fleet (both owned and ‘time charter’ – or leased – vessels), EEOI improved by 5%, decreasing from 40.7 to 38.6.

The increased roll-out of fuel-saving technologies is a good example of Uni-Tankers’ approach to ESG. To identify the best solutions, Uni-Tankers tests different technologies and initiatives. When a solution is identified that has a significant impact – such as the previously mentioned fuel-saving technologies – they are systematically adopted across all suitable vessels in our owned fleet. For the five remaining owned vessels where fuel-saving technologies haven’t been installed, it has been concluded such technology would not have a meaningful impact due to the vessels’ restricted operating profiles.

“Decarbonization is the most urgent matter in the shipping industry and at the top of our strategic agenda. Our constant focus on new technologies will play an important part in our efforts to meet industry targets,”

Lisa Clement Jensen

Head of Strategy, Uni-Tankers

Decarbonization is a key element in our formula for a better future

Decarbonization is a top priority in the shipping industry, with the IMO having revised its greenhouse gas (GHG) strategy in July 2o23 to target net-zero GHG emissions by or around 2050.

At Uni-Tankers, we fully acknowledge our responsibility to contribute to this global transition. Our fleet’s overall fuel consumption (on both owned and time-chartered vessels) accounts for 96% of Uni-Tankers’ GHG emissions (approx. 362,000 MT CO2E). That is why our immediate decarbonization efforts are focused on our fleet.

Middelfart, Denmark – 19 September 2023:

KPI OceanConnect supplies bespoke B30 biofuel blend to Uni-Tankers M/T Alsia Swan for successful trials on board the 5,700 DWT chemical tanker

Uni-Tankers, a leading tanker shipping company, and KPI OceanConnect, a leading global marine energy solutions provider, today announced they have completed the successful supply and trial of a bespoke blend of B30 biofuel on Uni-Tankers’ M/T Alsia Swan. The trials are an important step for understanding the emissions performance of biofuel and validating its potential to help cut carbon emissions.

The trial took place in Amsterdam on board Uni-Tankers’ 5,700 DWT chemical tanker M/T Alsia Swan. KPI OceanConnect arranged for the supply of 34,000 litres of bio grade fuel containing a 30% blend of FAME (fatty acid methyl esters). The fuel supply was part of a two-day trial, which saw emissions for the biofuel measured and compared with emissions for LSMGO under the same conditions.

KPI OceanConnect’s local team of traders worked with their Uni-Tankers partners to identify a biofuel to meet their bespoke needs. The team oversaw the blending process to ensure the fuel met precise specifications and was on hand for the delivery to ensure the specially blended product supplied for the M/T Alsia Swan trials was good quality.

Throughout the trial, tests were carried out at four different loads to assess the reliability and performance of the bio-fuel blend. Alongside trials of the B30 biofuel, Uni-Tankers ran identical operations for an LSMGO fuel of equal quality, allowing accurate comparisons of the B30 biofuel performance. Sampling and analysis for the trial was performed by a team from FORCE Technology

In results from the trial, Uni-Tankers saw particulate matter (PM) emissions reduced by as much as 42% when fuel supply was switched from LSMGO fuel to B30. Carbon monoxide (CO) emissions were also reduced by 18%. By using a blend of 30% biofuel and 70% fossil MGO, M/T Alsia Swan can cut emissions of CO2 by an equivalent amount. In a future of tightening regulation of greenhouse gas emissions, this will be an important interim step ship owners can take to maintain compliance and support decarbonization.

Lisa Clement Jensen, Head of Strategy at Uni-Tankers, commented: “The need to cut emissions is one of the most urgent matters in the shipping industry and we are very pleased to be working with KPI OceanConnect for the biofuel trials on the M/T Alsia Swan. Decarbonization is at the top our strategic agenda and we aim to contribute to a climate-resilient development of the shipping industry. These trials enable us to assess the potential and viability of biofuels as part of our ongoing decarbonization efforts.“

Jesper Sørensen, Global Head of New Fuels and Carbon Markets, KPI OceanConnect, commented on the project: “We are very pleased to be partnering with the Uni-Tankers team on this project to deliver high-grade biofuel for their vessel in Amsterdam. By sharing our knowledge and providing expert guidance on fuel strategies, including finding the right biofuel blend ratio to meet the specific needs of vessel operators, we aim to build partnerships with our clients that support their long-term success through the energy transition in shipping. For KPI OceanConnect our close partnership with Uni-Tankers is a model for delivering excellence to our clients.”

We are happy to announce a major expansion of our fleet, adding four new T/C vessels and the purchase of M/T Sedat Basak.

The expansion includes the acquisition of the modern ECO vessel M/T Sedat Basak, which will be added to Uni-Tankers’ owned fleet.

Additionally, we have signed a long-term deal for two new-building sister vessels to M/T Sedat Basak with stainless steel tanks which will be delivered in 2024 and 2025.

All 3 vessels are of modern ECO design and are approx. 30 pct more fuel efficient than conventional vessels of the same size

In addition, Uni-Tankers has also signed a contract with a Japanese partner for a long-term deal for two 12,500 dwt stainless-steel newbuildings with delivery in 2025 and 2026.

All four above-mentioned newbuildings are being built according to the highest safety and environmental standards and will comply with IMO Tier 3 NOx and Sox emission requirements.



“We are excited to announce this further significant expansion of our stainless-steel fleet and the renewal of our owned fleet,” says CEO Per Ekmann. “With these new vessels, we will be able to provide even greater service to our clients around the world.”

Massive turnaround with record result of EAT USD 61m

An effective turnaround strategy, favourable market conditions, and a streamlined organisation ready to seize each opportunity land record results for the Uni-Tankers Group.

Uni-Tankers, a Danish family-owned tanker shipping company in the intermediate and small tanker segment presents record earnings in its annual report for financial year 2022/23.

The report shows earning after tax of USD 61.0 million, an increase of USD 66.1 million from last year’s result despite constrained availability, higher cost of charter tonnage, and higher interest rates.

An impressive result which would not have been possible without the support and confidence of the owner family, Board of Directors, and not least an outstanding effort on the part of all on- and offshore staff.

“The impressive result of this year is a tribute to our entire organisation and their outstanding performance. I am very proud to have such dedicated staff – both onshore and off – who all in their own way have shown their loyalty and commitment to Uni-Tankers,” says Per Ekmann, CEO of Uni-Tankers, elaborating:

“Uni-Tankers has been on a tremendous journey these past years, growing our strategy, executing on strategic initiatives, and strengthening our organisation. This year, all the foundational work and preparation has aligned perfectly with an upturn market, and we are proud to be on a steady course for the future.”

The owners and Board of Directors of Uni-Tankers have backed the executive management both in executing on the turnaround strategy launched in 2018, which effectively streamlined operational processes and allowed the Group the flexibility to scale according to market conditions, as well as the Group’s new strategy, Stronger Together, launched at the beginning of this financial year.

“I have always had full confidence in Uni-Tankers and Per Ekmann’s ability to turn the company around. Building strategically on the strong core of Uni-Tankers, getting the right people in their right positions, and leveraging the determination and courage to make the necessary decisions in hard times have paid off. I am very proud of this year’s result as a clear example of the business acumen embodied by Uni-Tankers,” says Torben Østergaard-Nielsen, board member and co-owner of Uni-Tankers.

The combination of favourable market conditions, a clear business model with a perfect mix of owned and time-chartered vessels, along with an organisation that has been ready and able to seize each opportunity have allowed the Group to be agile and strengthen its position in the market with divestments of two non-strategic vessels and the addition of one new stainless-steel vessel with delivery in May 2023.

“This year’s impressive result comes from a strong foundation, a clear strategy, and the ability to execute – as well as the courage to take calculated risks. Our business model and strategy have allowed us to do just that, and we are thrilled to see the return this year,” says Klaus Nyborg, chairman of the board of Uni-Tankers.

During the year, Uni-Tankers remained focused on maintaining a cost-competitive operational setup and streamlining processes to improve efficiency.

“We are very proud that we have been able to land a record result of USD 61.0 million after tax – and at the same time reduce our total debt by 70 percent,” says CFO Thomas Thomsen, adding:

“It is a validation of our turnaround strategy and our continuous efforts to streamline our business and seize emerging opportunities.”

ESG is focal to Uni-Tankers

During the financial year, environmental, social, and governance (ESG) has been an area of focus for Uni-Tankers, and the shipping company has invested heavily in preparing for upcoming IMO and EU regulations.

Fuel-saving technologies have been installed on 11 of 16 vessels resulting in fuel savings of 8-15 percent and B30 biofuel blend tests are being conducted in collaboration with sister company Bunker Holding.

Along with carbon reducing initiatives, Uni-Tankers has strengthened its commitment to ensure diversity, equality, and inclusion and fostering strong relations within the company, as well as worked intensely to prepare for upcoming regulations such as the EU emissions trading system (ETS) which comes into effect from 2024.

“For us, shipping is a matter of chemistry – the chemistry between people and the world we live in. As a result, remaining at the forefront of the ESG agenda and staying compliant with all legislations and guidelines are pivotal to us, as we firmly believe in a healthy and sustainable future for the shipping industry,” says Per Ekmann.

A total of 13 owned vessels are now fully compliant with IMO’s Energy Efficiency Existing Ship Index (EEXI), and the remaining three vessels will be compliant later this year. At the end of financial year 2022/23, Uni-Tankers completed a decarbonization deep-dive to prepare for the increasingly stringent demands to reduce greenhouse gas emissions and carbon intensity – and in the coming financial year the Group will set targets and finalize a decarbonization roadmap following the MEPC 80 session later this year. To further track progress, the Group has established a clear ESG governance structure with defined ownership across all initiatives.
