Mitsui O.S.K. Lines, Ltd. (MOL) on Wednesday (1 November) announced that an MOL Coastal Shipping-operated 499 GT coastal roll-on/roll-off (RoRo) vessel, Tetsuun Maru No.1, was successfully operated using biofuel made by mixing used cooking oil (UCO) directly with heavy fuel oil.

The biofuel used on the vessel is made by mixing used cooking oil derived from vegetable oils and fats in Japan without chemical treatment with heavy fuel oil. This marks Japan's first initiative to use this kind of biofuel to marine vessels.

Hanwa Co., Ltd. supplied the biofuel to the vessel in the Chukyo region as part of a research programme on marine applications of biofuels by Japan's Ministry of Land, Infrastructure, Transport and Tourism, in cooperation with Tokyo Steel Manufacturing Co., Ltd., the cargo shipper. 

The vessel operated on the biofuel mixture for about a month, plying a route between Mikawa Bay and Tokyo Bay, and reported no flammability problems or other issues.

Until now, the main raw material for biofuels has been Fatty Acid Methyl Ester (FAME), which is produced by chemical processing of waste cooking oil and methanol. In this project, used cooking oil was mixed with heavy oil A (mixing ratio of Bio was 24%) in almost its original form as straight vegetable oil (SVO) and used in a general-purpose ship type, 499 GT coastal vessel. 

Since the SVO undergoes no methyl esterification or hydrogenation process, it is likely to reduce carbon dioxide (CO2) emissions even more than other biofuels and can be supplied at a lower cost.

Integr8 report: Two-thirds of residual bunker fuels still sold with pre-2017 ISO specs

Integr8 Fuels, the bunker trading and brokerage arm of Navig8, on Tuesday (11 June) announced the release of its Bunker Quality Trends Report Q1 2024, which revealed several issues including the impact of the Red Sea closure on VLSFO compliance and emerging bunker quality trends.

In the latest report, bunker quality and claims manager Chris Turner advised shipowners and bunker buyers on how they can improve their buying processes and performance. 

Analysing data from over 130 million metric tonnes of deliveries to assess fuel quality trends and challenges from region-to-region, Turner revealed the most pressing quality issues the industry is up against. 

These include:

  • Red Sea closure affecting VLSFO compliance for vessels rerouting around Africa
  • Global VLSFO compliance suffers as suppliers stretch barges to cash in on rising HSFO
  • demand, driven by increasing scrubber numbers
  • Two-thirds of fuels are still sold with obsolete (pre-2017) specifications. Can the new ISO specs finally shake up old school practices?
  • Profit margin-motivated blenders push more HSFOs over ISO limits
  • VLSFO sulphur off specs worsening in the ARA and partly driven by high- to low sulphur barge switching

Red Sea closure impact on VLSFO compliance

Geopolitical events often have a knock-on effect on fuel quality, sometimes relating to blending economics, and occasionally, also relating to the impact on barge infrastructure because of rapidly changing demand.

Since October 2023, many more vessels have been rerouting around Africa rather than travelling via the Red Sea, resulting in a significant increase in volume of HSFO demand, with a ripple effect stretching as far as Barcelona. During the same period, there has been a 30% increase in VLSFO sulphur off specification incidents in ports along the African coast and nearby Spain, which upon closer inspection, show a root cause of affected barges also carrying HSFO.

Integr8 Fuels’ analysis has identified suppliers running a similar model who are unaffected - this likely due to their infrastructure allowing double valve segregation and separate manifolds onboard the barge preventing any cross-over contamination, and/or proper management of grade changeover.

The increase in HSFO demand is also putting pressure on supply models.

Another factor is the significant increase in the number of vessels equipped with scrubbers, resulting in a far higher demand for HSFO than in recent years with data available to Integr8 suggesting approximately 100 million MT of deadweight tonnage being either delivered or retrofitted with scrubbers in 2023. This combined with the price spread which remains very appealing, and scrubber assets travelling further at higher speeds, continues to support the demand going forwards.

Suppliers of course want to meet this increased demand and in doing so place transitional temporary pressure on existing assets or could be forced into a sea change in strategy, both of which may result in the practice of storing both HSFOs and VLSFOs onboard the asset.

This is made apparent by increased sulphur off specification occurrences with the root cause being the switching of grades by certain suppliers, in ports including but not limited to Barcelona, Callao and Hong Kong.

New ISO specs

The International Organization for Standardization’s (ISO) recently launched ISO 8217:2024 standards present a rare opportunity to do away with the industry’s reliance on obsolete fuel specifications. This is no easy task as research from Integr8 shows that two-thirds of residual bunker fuels and three-quarters of distillate bunker fuels are still sold with pre-2017 specifications.

ISO 8217:2024 introduces several important amendments. Notably, it sets minimum viscosity limits across all residual grades, addressing handling issues with low-viscosity fuels. It also identifies specific chemical species linked to operational problems, such as organic chlorides, and incorporates international testing standards. The new specification prepares the industry for the growing use of biofuel blends by establishing new testing parameters for these fuels, such as FAME content and net heat of combustion.

There are however missed opportunities, namely related to de-minimis levels of organic chlorides and cold flow properties.

Suppliers may again attempt to avoid the small print on organic chlorides as they have previously done with Clause 5, which could possibly have been better addressed by incorporating a maximum limit in tables. Cold flow properties must only be reported, not guaranteed, leaving the potential need for buyers to seek additional guarantees outside ISO 8217:2024. This remains a concern as certificates of quality (where such values are reported) often lack reliability when provided at a distant time from delivery.

Despite these challenges, the ISO 8217:2024 specification represents a substantial step forward, providing the necessary framework to address many current fuel quality issues. The uptake of the 2024 specification will depend significantly on ship owners demanding these new standards be incorporated into charterparty agreements. By doing so, owners can drive the transition from outdated specifications to the latest version, paving the way for a more reliable and efficient future in marine fuel standards.

Global HSFO off specs

Global HSFO quality has worsened in the past six months. The number of off-specification HSFO samples has gone up from 3% to 3.4%, and this is significantly higher than for VLSFO (2.1%) and MGO (2.8%).

Profit-motivated blending can go some way to explain the deteriorating HSFO trend. Almost half of HSFO off specs have been blending-related and come as a result of blending close to HSFOs density and viscosity limits, Turner argues. Water content is the second most likely usual off spec suspect and has made up around a third of HSFO off specs.

But fortunately, neither density, viscosity nor most of the water off specs qualify as so-called “critical” or “high risk” off specs. They are not likely to lead to serious engine trouble or debunkerings, which can cost shipowners dearly. These off specs are typically economically motivated. Density and viscosity off specs are more common for HSFO than for VLSFO and LSMGO because they are the blending targets for HSFO, and blenders have an incentive to blend as close to those limits as possible to save money.

VLSFO sulphur off specs

Sulphur is the biggest off spec concern for VLSFO. Again, this has to do with blending as the 0.50% sulphur limit is the target that blenders have their eyes on. Blending too far from the limit can eat into your profit margins, and we have seen the average sulphur contents in VLSFOs creep up in both the ARA and Singapore in the past six months.

In Singapore, you were 2.5 times more likely get a VLSFO stem with a sulphur content of 0.51-0.53% in the past six months as you were getting one in the preceding six-month period. It is evident that blending is being optimised towards the 0.50%.

But while only 0.3% of VLSFOs test off spec for sulphur in Singapore, the ARA has seen 2% of VLSFOs testing off spec. In the ARA, “we regretfully report that we are almost twice as likely to face a sulphur off specification incident now than in the previous reporting period,” Turner wrote.

Fresh Carriers and Zespri complete first biofuel trial onboard “Kakariki”

New Zealand's largest horticultural exporter Zespri on Tuesday (11 June) said one of its international shipping partners, Fresh Carriers Co Ltd (FCC), has successfully completed a trial using biofuel in a charter vessel operating between Hong Kong and New Zealand, according to Zespri on Tuesday (11 June).

The purpose of the trial was to test the performance of the ship’s engines when burning biofuel.

The cargo ship Kakariki bunkered the biofuel in Hong Kong at the end of last month before starting its voyage south, arriving at the Port of Tauranga at the weekend. 

The vessel was powered by a blend of biofuel which is made from used cooking oil. The Kakariki bunkered the biofuel in Hong Kong because there is none available in New Zealand - if and when biofuel does become available in New Zealand it will present more opportunities for Zespri’s chartered ships to burn this low-emission fuel.

Zespri Chief Operating Officer Jason Te Brake said the biofuel trial by FCC is a collaborative step forward for the industry as it seeks to decarbonise and future proof through innovative solutions such as low emissions shipping.

“With Zespri having limited ability to directly reduce shipping emissions ourselves, we’re working with key shipping and distribution partners like FCC to increase the efficiency of our shipping and logistics, and make the transition to low emissions fuels.

“The biofuel trial with FCC is an important step forward and has given us both important technical insights, with the Kakariki monitored throughout its journey to make sure the biofuel performed well with no unforeseen technical issues. It’s fantastic to see it dock successfully in Tauranga.”

FCC Director Toshiyuki Koga said FCC was proud to see the Kakariki, which is the company’s first vessel to trial biofuel, arrive safely in Tauranga.

“We have been in discussions with Zespri for a number of months about carrying out this trial and are now looking forward to further biofuel trials using other FCC vessels. We are also considering a northbound trial taking Zespri Kiwifruit to market this season.

“Biofuel supply chains are complex and there is still work to be done to ensure stable supply, however this trial is a first step towards decarbonisation with Zespri.”

Jason Te Brake added: “New Zealand’s place at the bottom of the South Pacific Ocean means accessing low emissions fuel options is a challenge, and we are actively seeking partners to shore up access to more sustainable fuels to meet our ambitious targets and the expectations of our customers and consumers.

“It’s been positive working with our long term partner FCC recognising the importance of decarbonising and future proofing the industry. This trial is a step forward and we’re pleased to be on the path to introducing low emissions fuels to carry Zespri Kiwifruit to our markets around the world in the future.”
