Marine fuel testing and marine surveying business Maritec Pte Ltd (CTI-Maritec) on Tuesday (5 July) issued an alert regarding presence of chemical contaminants in ARA region bunkers and its effects on fuel pumps and exhaust system. 

Maritec has tested several VLSFOs delivered in the ARA region to be observed with the presence of chemical contaminants in the recent months. These VLSFOs also indicated elevated potassium content and acid number.

From these samples, CTI-Maritec has obtained feedback from vessels encountering rapid and excessive wear on fuel pumps on main propulsion engines and a tendency for increased deposit formation in the exhaust system.

Forensic analysis by Gas Chromatography and Mass Spectrometry techniques, specifically ASTM D7845 GC/MS and Solid Phase Extraction (SPE) GC/MS, on some of the samples revealed the presence of the following compound groups at abnormally high concentrations

  • Fatty Acids and Monoglycerides (>1000ppm)
  • Alkylresorcinols (>2000ppm)
  • Phenolic compounds (>1000ppm)

Fatty acids and Monoglycerides are acidic compounds commonly found in fuels where the FAME content has broken down in the presence of water and have known to cause costly accelerated wear in fuel oil injection pumps. The presence of these compounds can also suggest an inclusion of substandard Bio-fuels into the blend. This also explains the high potassium content in the fuel as Potassium Hydroxide (KOH) is one of the possible catalysts used in the production of bio-diesel. The separation of the spent catalyst out from the final product is a complicated and expensive process. The increased potassium can also contribute towards the total ash forming tendency of the fuel leading to abnormal deposit formation in post combustion exhaust system components.

The presence of Alkylresorcinols and phenolic compounds suggests the inclusion of shale oil which is allowed as per the definition of ‘petroleum fuel’ in ISO 8217 standards. CTI-Maritec’s experience however has shown that the presence of these compounds tends to cause fuel instability leading to issues like filter blockages and purifier bowl overloading. This is despite the Total Sediment potential tests being within specification. Any sludge not capable of being removed by the fuel treatment system can cause combustion issues in the main engine.

If your vessel is expected to bunker in the ARA region; CTI Maritec advises to check the pre-bunkering certificate of quality or Manifold sample test results for signs of abnormally high potassium content (>110ppm) and/or high total acid number (>1.5mgkoh/g) and pre-emptively analyze the bunker fuels by Gas Chromatography and Mass Spectrometry (GC-MS) that can reveal the presence of undesirable compounds in the fuel thus safeguarding vessel operations.

In every case, CTI Maritec urges bunker fuel receivers to ensure thorough attention is given to the witnessing of correct sampling procedures during bunkering, counter-sealing and recording of seals in the bunker delivery note and any other documentation required to ensure correct representative samples are obtained during the bunkering process.

Collecting objective evidence on the storage, treatment and usage of the fuel is to be always given a high priority in the event an operational problem occurs to determine if the fuel used was one of the root causes for a machinery failure.  

This document however does not reflect on the overall quality of fuel being supplied at ARA region.

The presence of off-spec marine fuels at the ARA region has been detected since late June:

Methanex to acquire OCI Global international methanol business

Methanex Corporation (Methanex) on Sunday (8 September) announced that it has entered into a definitive agreement to acquire OCI Global’s (OCI) international methanol business for USD 2.05 billion. 

The transaction includes OCI’s interest in two world-scale methanol facilities in Beaumont, Texas, one of which also produces ammonia. The transaction also includes a low-carbon methanol production and marketing business and a currently idled methanol facility in the Netherlands.

“This is a unique opportunity to create value by acquiring two highly attractive North American methanol assets that will further strengthen our global production base and we expect it will be immediately accretive to free cash flow per share,” said Rich Sumner, President and Chief Executive Officer of Methanex. 

“The Beaumont plants benefit from access to North America’s abundant and favourably-priced supply of natural gas feedstock, and are expected to increase our global methanol production by over 20 percent.”

“We believe the transaction will provide significant long-term value to Methanex shareholders while aligning with our strategic objectives of industry leadership, operational excellence, and financial resiliency,” said Mr. Sumner. 

“From an operating perspective, we have a shared culture of safety and operational excellence, and we expect the OCI team will help us build new skills in ammonia while enhancing our capabilities in the evolving business of low carbon methanol production and marketing.”

Nassef Sawiris, Executive Chairman of OCI, added, “We are pleased with the opportunity to achieve a significant ownership position and are highly confident in Methanex’s ability to create enduring value for shareholders. As the global leader committed to safety and operational excellence, we identified Methanex as the natural owner of OCI Methanol at the outset of our strategic process, which we initiated in the spring of 2023.”

As part of the transaction, Methanex will acquire the following:

  • A methanol facility in Beaumont, Texas with an annual production capacity of 910,000 tonnes of methanol and 340,000 tonnes of ammonia. This plant was restarted in 2011 and since that time the plant has been upgraded with USD 800 million of capital for full site refurbishment and debottlenecking.
  • A 50 percent interest in a second methanol facility also in Beaumont, Texas, operated by the joint venture Natgasoline LLC (Natgasoline). The Natgasoline plant was commissioned in 2018 and has an annual capacity of 1.7 million tonnes of methanol, of which Methanex’s share will be 850,000 tonnes.
  • OCI HyFuels, which produces low-carbon methanol and sells industry-leading volumes with trading and distribution capabilities for renewable natural gas (RNG). With nine years of experience in the low-carbon methanol business and with an array of blue-chip customers, this will enhance Methanex’s existing Low Carbon Solutions function with additional expertise in this developing segment.
  • A methanol facility in Delfzijl, Netherlands with an annual capacity to produce 1 million tonnes of methanol. This facility is not currently in production due to unfavourable pricing for natural gas feedstock.

Closing of the transaction is expected in the first half of 2025. The transaction has been approved by the boards of directors of both companies and is subject to receipt of certain regulatory approvals and other closing conditions including TSX approval for the issuance of Methanex shares to OCI.

The transaction is also subject to approval by a simple majority of the shareholders of OCI. The largest shareholder of OCI, has signed an agreement to vote for the transaction.

Corvus Energy gas-safe marine fuel cell system receives type approval by DNV

Corvus Energy, supplier of energy storage systems (ESS) for maritime applications, on Wednesday (4 September) announced that the Corvus Pelican Fuel Cell System has received Type Approval from classification society DNV.

The system, which was developed through the three-year-long H2NOR project, is the first Fuel Cell System (FCS) designed to be inherently gas-safe, making it the safest fuel cell system in the market.

Corvus Energy said receiving type approval from DNV confirmed that the Corvus Pelican Fuel Cell System meets the most stringent performance and safety standards required by the maritime industry.

Olaf Drews, Head of Engines & Pressurized Equipment Maritime, said: “It is a special fuel cell system, because the Pelican uses nitrogen for inerting of the fuel cell space.”

“It is the first fuel cell system that uses this technology and this brings it to a very preferred safety level. This is a milestone, and we look forward to the first ship project.”

Despite technology improvements and advancements in battery electric vessels, most vessels cannot achieve zero-emission operations for extended periods of time using batteries alone. For vessels on longer routes and vessels that are unable to charge often enough, we need to add clean fuel and fuel cells to enable extended zero-emission capabilities.

CEO of Corvus Energy, Fredrik Witte, said: “Toyota’s unsurpassed knowledge in developing high-quality and efficient fuel cells, in addition to the strong collaboration and high level of maritime experience among the partners in this development project, has been key.”

“This is a milestone for net zero shipping. We now have a high-quality range extender to add to our existing ESS portfolio with the scalability and the safety needed to be a real driver in the future of marine decarbonization.”

The first Corvus Pelican Fuel Cell System is produced and ready to be installed onboard MS Skulebas, a 35-meter fishing and training vessel owned by Vestland County and operated by Måløy Upper Secondary School in Norway. 

The vessel already has a 1 MWh battery system onboard. By adding the Corvus Pelican Fuel Cell System and hydrogen storage, the vessel will be able to operate for four days on zero emission.
