Bunker fuel testing and marine surveying business Maritec Pte Ltd (CTI-Maritec) on Monday (1 April) published its latest whitepaper related to the Maritime and Port Authority of Singapore’s (MPA) move to introduce enhanced testing parameters for marine fuel batches intended to be delivered as bunkers in the port of Singapore from 1 June. 

In accordance with the MPA’s Port Marine Circular No 3 of 2024, from 1 June 2024 onwards, bunker suppliers in the Port of Singapore must ensure that:

  • Residual & bio-residual bunker fuel do not contain Chlorinated Organic Compounds (COC) above 50mg/kg and are free from inorganic acids.
  • COC must be tested using the EN 14077 accredited test method and shall be reported in the “Certificate of Quality” (COQ) provided to receiving vessels.
  • Inorganic acids must use the ASTM D664 accredited test method as prescribed in ISO 8217 and the Strong Acid Number (SAN) (in addition to the Total Acid Number (TAN) shall be reported in the COQ (i.e. SAN = 0) provided to receiving vessels. For distillate / bio-distillate bunker marine fuel batches, SAN must be tested as per ASTM D664 test method and reported in the COQ.
  • Residual marine fuels are free from polystyrene, polypropylene & polymethacrylate. These can be tested by filtration, microscopic examination, & Fourier-Transform Infrared spectroscopy analysis. 

In view of the above, CTI-Maritec shared its insights and recommendations in the paper, titled Insights & Recommendations on Singapore MPA’s Enhanced Testing Parameters for Marine Fuel Batches, related to the testing of COCs, TAN and SAN for all bunker supply in Singapore, and its recommendations for testing Polymers for reported problem cases.

In the conclusion of the whitepaper, CTI-Maritec said the issue of chemical contamination has plagued the bunker industry for years, and the risk of receiving contaminated bunker fuels is likely to persist.

“This is mostly due to complex bunker supply chains, which consists of a network of different stakeholders including refineries, traders, and physical suppliers operating their own barges, with some performing their own fuel blending operation,” it said.

“However, with the imminent enforcement of MPA’s Port Marine Circular No 3 of 2024, the stage is set to raise the bar of the bunkering fuel quality in the Port of Singapore and further support stronger vessel health.”

CTI-Maritec added the new requirements in Singapore could also pave the way for other international Port Authorities to implement the same requirements for their bunker suppliers.

“Furthermore, a key learning from the 2022 incidents is the critical need for bunkering buyers / ship owners / vessels to adopt, as a standard practice, an enhanced fuel testing approach as a pre-emptive measure in securing their vessel’s health,” it added, referring to the bunker contamination incident in Singapore in February 2022, where about 200 ships were supplied with High Sulfur Fuel Oil (HSFO) containing high levels of Chlorinated Organic Compounds (COC) in the Port of Singapore. 

The firm encouraged bunker buyers to consult the bunker suppliers in advance and have proper contractual agreement for the quality of fuel bunkered.

Manifold Times previously reported the move by MPA for enhanced checks for marine fuel delivered at Singapore port receiving largely positive feedback from several local bunker fuel testing agencies including VPS and Intertek.

With mandatory enhanced checks for marine fuel delivered at Singapore port coming into effect on 1 June, bunker fuel testing and marine surveying business Maritec Pte Ltd (CTI-Maritec) has published a newsletter providing recommendations on vital pre-emptive fuel testing measures vessels should be taking as part of their routine fuel testing and also recommendations on optimal testing options available when deep-dive analysis is required to determine a root cause: 

Introduction

On 8 February 2024 the Maritime and Port Authority of Singapore (MPA) issued a Port Marine Circular No 3 of 2024 regarding the implementation of enhanced testing parameters for marine fuel batches intended to be delivered as bunkers in the Port of Singapore in addition to the existing quality assurance measures.

In accordance with the MPA’s Port Marine Circular No 3 of 2024, from 1 June 2024 onwards, bunker suppliers in the Port of Singapore must ensure that:

  • Residual & Bio-residual bunker fuel do not contain Chlorinated Organic Compounds (COC) above 50mg/kg and are free from inorganic acids.
  • COC must be tested using the EN 14077 accredited test method and shall be reported in the “Certificate of Quality” (COQ) provided to receiving vessels.
  • Inorganic acids must use the ASTM D664 accredited test method as prescribed in ISO 8217 and the Strong Acid Number (SAN) (in addition to the Total Acid Number (TAN) shall be reported in the COQ (i.e. SAN = 0) provided to receiving vessels. For distillate / bio-distillate bunker marine fuel batches, SAN must be tested as per ASTM D664 test method and reported in the COQ.
  • Residual marine fuels are free from polystyrene, polypropylene & polymethacrylate. These can be tested by filtration, microscopic examination, & Fourier-Transform Infrared spectroscopy analysis.

Testing Recommendations in line with MPA Enhanced Parameters to Protect Your Vessels:

In view of the above, CTI-Maritec recommends fuel testing protocols as depicted in the chart below (as routine pre-emptive measures and/or for deep dive requirements to detect the root cause) to help safeguard vessel health.

Our recommendations are primarily focused at COCs and SAN detection for bunker supply in Singapore, while recommendations for testing Polymers are advised for requirements of reported problem cases or when highly abnormal GCMS findings of chemical compounds like Styrene, DCPD and Indene are detected.

VPS conducts assessment on first SIMOPS methanol bunkering op in Singapore

Marine fuels testing company VPS on Tuesday (28 May) said it was appointed by OCI Methanol Europe, part of the OCI Global Group, to conduct a quantity and quality assessment of a methanol fuel delivery to Eco Maestro in Singapore.

Captain Rahul Choudhuri, President Strategic Partnerships, VPS, said VPS survey experts Rafael Theseira and Muhd Nazmi Abdul Rahim were at hand during the methanol bunkering to ensure the 300 metric tonnes of methanol transfer was carried out smoothly, having been involved in the first methanol bunkering a year ago. 

Manifold Times recently reported X-Press Feeders, Global Energy Trading Pte Ltd (GET), and PSA Singapore (PSA) successfully completing the first simultaneous methanol bunkering and cargo operation (SIMOPS) in Singapore.

A X-Press Feeder container vessel, Eco Maestro, on its maiden voyage from Asia to Europe was successfully refuelled with close to 300 mt of bio-methanol by GET, a MPA licensed bunker supplier, using MT KARA

The ISCC-certified bio-methanol used for the SIMOPS was produced by green methanol producer OCI Global and supplied via GET, a ISCC-certified supplier.

Captain Choudhuri said the role of the marine, petroleum or bunker surveyor has evolved over the years in shipping and maritime affairs, but the principles have not - and that is to provide independent assessment of the quality and quantity of the product transfer. 

“This may seem obvious but this quality and quantity control is crucial to avoid commercial discrepancies, shortages or fraud,” he said.

“Safety training is critical and we have been on top of this having completed the required MPA fire-fighting course and the IBIA Methanol training course. We will work more with the Singapore Maritime Academy for trainings in future,” he added.

In August last year, Singapore-headquartered independent common carrier X-Press Feeders launched its first ever dual-fuel vessel Eco Maestro in China.

Manifold Times previously reported VPS stating it was the first company to complete a methanol bunker quantity survey (BQS) operation in Singapore on 27 July last year.

VPS was appointed by Maersk and Hong Lam Marine Pte Ltd, to undertake the very first bunker quantity survey (BQS) of a methanol fuel delivery, supplied by Hong Lam to the Maersk vessel on its maiden voyage to Europe.

Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Thursday (16 May) released a bulletin to highlight significant changes to the ISO 8217:2024 as compared to the 6th (2017) edition.

This bulletin is to bring all clients' attention to the imminent publication of the new version of ISO 8217 and we will be updating again as soon as ISO secretariate uploads the final version of ISO 8217:2024 on its website.

The increasing demand of environmental legislation is leading a marine fuel transition towards oil products derived from synthetic and renewable, recycled or alternative sources. There are a number of significant changes as compared to the 6th (2017) edition both in terms of extent and content.

  • The most noticeable change is to the residual grades in that these will now be divided into three separate tables
    • 4 RM grades not exceeding 0.50% or 0.10% sulphur,
    • 5 RF (biofuel) grades covering unrestricted % FAME content
    • 5 RM grades above 0.50% sulphur.
  • Similarly for the distillates each of the grades, apart from DMX, has a corresponding FAME blend version of unrestricted %
  • In the case of the FAME blends, residual or distillate, the percentage of FAME component is to be advised to the receiver at delivery
  • The FAME used is generally to have met either the EN 14214 or ASTM D6751
  • The net specific energy is to be reported by the supplier
  • Suppliers to ensure all fuel grades are free of organic chlorides
  • Each of the category tables now includes specific reference to the normative paragraphs of the standard
  • The principal change to the residual grades is that these all now also include a minimum, in addition to the existing maximum, viscosity
  • To enhance control of asphaltene stability in the case of sulphur limited RM grades and the RF grades, this is now limited in terms of total sediment by thermal ageing to the same limit as before but additionally the accelerated and existent values are also to be reported by the supplier

It is also worth noting that generally the limit values, for both the distillates and residuals, have not fundamentally altered although for residuals there has been a redistribution across the reduced number of grades.

Lloyd’s Register FOBAS has been heavily involved in guiding and contributing as a member of the ISO and CIMAC fuels working groups and for our position we would highly recommend adopting this new standard in all fuel purchasing/sourcing processes whenever possible. We will have a number of additional testing options available which we will further explain on request.

As mentioned, a far more detailed bulletin will be issued shortly supported by a list of FAQ to further support your operations.
