Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Tuesday (29 April) released a bulletin regarding testing of fuel samples from different vessels, which bunkered in Istanbul, that have reported problems with fuel injection equipment seemingly caused by a substance sticking and seizing the jerk type fuel pumps:

In recent days, FOBAS has tested fuel samples from different vessels that have reported problems with fuel injection equipment seemingly caused by a substance sticking and seizing the jerk type fuel pumps. These vessels bunkered fuel in March and April this year from Istanbul.

These fuels have been further investigated with extended chemical analysis showing a number of chemical species present with some at very high levels.

Various chemicals were found including 4-Cumyl Phenol and Cyclohexane Diol at high levels. Resin acids and Acrylates were also identified along with unusually high levels of DCPD (Dicyclopentadiene), Indene and trace levels of Tetrachloroethylene.

Not all these chemicals may be contributing to the problems, but they are in a pattern seen in some problem fuels from Antwerp and Rotterdam in 2024 and a number of problem fuels from Houston in 2023 and 2018. Some of these chemicals can polymerise and are used in the manufacture of resins and plastics and may be reacting together under the heat and pressure of the fuel injection system.

These fuels were found to be on-spec based on standard routine analysis. However, there are some particular parameters of note. Viscosity was low at around 40cSt, acid numbers were high (1.50 – 2.50mgKOH/g) and all fuels were VLSFO with sulphur content <0.50%. This low viscosity and high acid number pattern aligns with other contaminated fuels seen in Houston in 2023).

We would suggest that if you have bunkered in the last 2-3 months in Istanbul to be particularly cautious with the use of the fuel. In particular if the fuel has a low viscosity, around 50cSt or lower, high acid number >1.00mgKOH/g or high sediments, we would suggest to discuss further testing options as this problematic fuel may not be isolated to only two vessels.

It should also be noted and suppliers reminded that any fuel purchased against the ISO8217 standard must meet the general requirements of clause 5 as well as limits in the characteristics tables. Clause 5 includes the statement that the fuel should be a “homogeneous blend of hydrocarbons derived from petroleum refining” and be free from any substance or chemical waste that “jeopardizes the safety of the ship or adversely affects the performance of the machinery”.

Global marine fuel supply and procurement firm TFG Marine on Tuesday (29 April) announced the company’s successful trial and imminent roll-out of ZeroNorth’s electronic bunker delivery note (e-BDN) solution for its customers in the Port of Sohar, in Oman.

A first for the Middle East region following the successful deployment of the same technology earlier this year by TFG Marine at the Port of Singapore. The eBDN trial in Oman was completed in collaboration with ZeroNorth and SGTraDex, using the Singapore standards as a benchmark.

Kenneth Dam, Global Head of Bunkering, said: "We’re excited to partner with ZeroNorth, Fratelli Cosulich Group Bunkers, SGTraDex and SOHAR Port and Freezone to shortly introduce e-BDNs to our customers here in Oman.”

“This technology, that we have already successfully introduced in Singapore is yet another step in modernising our industry. It will streamline the bunker delivery process, cut administrative burdens, enhance digital documentation and help build a smarter, more connected bunkering sector.”

“We remain committed to establishing e-BDNs as a global standard for bunker fuel delivery and will continue to work closely with port authorities to advocate for and deploy this technology across our operations.”

Dam made the announcement at the Oman Maritime, Ports and Energy Forum, during the panel discussion on The Transformative Power of Data: The Evolving Role of Digitalisation in Shipping and Bunkering.

Dam added the fully digital solution — accessible through TFG Marine’s mobile app and integrated with SGTraDex’s digital infrastructure, — will enable the inclusion of additional data, such as mass flow meter readings during fuel deliveries.

“By integrating this technology, we will drive significant improvements in efficiency, accuracy, compliance, and sustainability across our operations, complementing the global mass flow meter rollout across our fleet and reinforcing TFG Marine’s position at the forefront of the modern bunkering industry,” he said. 

Manifold Times previously reported TFG Marine announcing the introduction of ZeroNorth’s e-BDNs for its customers in Singapore during 23rd Singapore International Bunkering Conference (SIBCON) by the end of 2024.

In November last year, TFG Marine announced its first digitalised marine fuel delivery in Singapore using electronic bunker delivery notes (e-BDNs).

Its team supplied VLSFO bunker fuel to Pacific Basin Shipping Limited’s Illovo River bulk carrier, marking the first of four bunkering deliveries that month where this new technology was successfully deployed.

Hercules Tanker Management (HTM) on Tuesday (29 April) announced that its tanker Mount Kibo has been successfully supplied with B30 bunkers by tanker Hercules Sky, another HTM-owned vessel which is operated by Peninsula.

The operation marked the first biofuel supply to the HTM fleet.

HTM is the shipping venture launched last September by John A. Bassadone, founder and CEO of independent marine fuel supplier Peninsula. 

HTM said the operation carried out in the Strait of Gibraltar aligns with the recent discussions at MEPC 83, where key decisions were made to advance maritime decarbonisation, including new fuel standards and a global pricing mechanism for emissions. 

“Additionally, this initiative supports the objectives of the FuelEU Maritime Regulation, which promotes the use of renewable, low-carbon fuels and clean energy technologies for ships,” it said.   

“By utilising biofuels, we are contributing to the reduction of greenhouse gas emissions and supporting the industry's transition towards cleaner energy solutions.”
