Cases of off-spec bunker fuels decreased at Singapore port between the period of 1st to 14th July 2018, according to fuel quality data provided by Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS).

There were zero cases of off-specs regarding cat fines recorded during the period, compared to a single case noted within the earlier fortnight.

The report was prepared to fuel tested in accordance to ISO 8217 6th edition.

The U.S. Coast Guard notes standard ISO 8217 tests will not able to detect issues specifically concerning phenolic compounds found in marine fuel.

The top three off-spec bunker ports for the period between 1st to 14th July 2018 are as follows:

SG bunker performance May 2025

Bunker fuel sales at Singapore port inched forward by 1.1% on year in May 2025, the highest volume seen in 2025, according to Maritime and Port Authority of Singapore (MPA) data.

In total, 4.88 million metric tonnes (mt) (exact 4,878,100 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in April, up from 4.83 million mt (4,826,800 mt) recorded during the similar month in 2024.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in May (against on year) recorded respectively 1.89 million mt (+8.6% from 1.74 million mt), 2.45 million mt (-7.2% from 2.64 million mt), 1,200 mt (from zero), 1,700 mt (-88% from 14,300 mt) and zero (from zero).

Bio-blended variants of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in May (against on year) recorded respectively 40,900 mt (+671.7% from 5,300 mt), 95,800 mt (+97.9% from 48,400 mt), 700 mt (from zero), zero (from zero) and zero (from 300 mt). B100 biofuel bunkers, introduced in February this year, recorded 1,900 mt of deliveries in May.

LNG and methanol sales were respectively 45,000 mt (-7.8% from 48,800) and zero (from 1,600 mt). There were no recorded sales of ammonia for the month and so far in 2025.

RESIZED Panama

Bunker fuel sales at Panama increased by 13.9% in May 2025, according to the latest data from La Autoridad Maritima de Panama, also known as the Panama Maritime Authority (PMA).

Total bunker sales at Panama was 453,397 metric tonnes (mt) in May 2025, compared to sales of 398,964 mt during the similar period in 2024.

In May 2025, the Pacific side of Panama posted bunker sales of 368,419 mt; 213,589 mt of VLSFO, 117,297 mt of RMG 380, 1,538 of marine gas oil (MGO), and 35,995 mt of low sulphur marine gas oil (LSMGO) were delivered.

The similar region saw total marine sales of 323,084 mt a year before in May; with VLSFO sales at 184,761 mt, RMG 380 sales at 112,011 mt, MGO sales at 2,199 mt, and 24,113 mt of LSMGO being sold.

Panama’s Atlantic side, meanwhile, recorded total bunker fuel sales of 84,978 during May 2025; the figure comprised 63,318 mt of VLSFO, 8,575 mt of RMG 380, 1,987 mt of MGO, and 11,098 mt of LSMGO.

It saw total sales of 74,980 mt in May a year before; with VLSFO sales of 59,855 mt, RMG 380 sales of 6,508 mt, 1,545 mt of MGO, and LSMGO sales of 7,072 mt.

GCMD path to zero carbon shipping

The Global Centre for Maritime Decarbonisation (GCMD) on Friday (13 June) launched its Path to Zero-Carbon Shipping – Insights from ammonia transfer trial in the Pilbara report.

The document captures key learnings from a pilot involving the ship-to-ship transfer of liquid ammonia between two gas carriers — the Green Pioneer and the Navigator Global — at anchorage off Port Dampier in the Pilbara, Western Australia.

The trial demonstrated that ship-to-ship ammonia transfer at anchorage can be both safe and practicable, provided that recommended safeguards and operational controls are implemented.

To share these crucial learnings with the industry, the report offers quantitative insights from executing the trial, forming a reference for future pilots and eventual commercial-scale operations.

The report offers:

Project background and objectives: An overview of the trial’s goals and operational context

Detailed safety studies covering four key areas:

  • Feasibility: Response motions and mooring analysis
  • Risks: HAZID and HAZOP findings and mitigations
  • Consequences: Computational Fluid Dynamics (CFD) plume dispersion modelling
  • Response: Emergency Response measures and protocols

Operation execution overview: A detailed account of the actual transfer operation, including the Joint Plan of Operations (JPO), assets deployed and a timeline of key events.

Optimising ammonia bunkering: Operational recommendations for both bunker tankers and receiving vessels, covering aspects such as transfer system setup, manifold arrangement, sample collection and more. A checklist of ERP resources required onboard is also included.

“In the past, bunkering guidelines took years to develop and were typically derived from experience with actual operations,” said Professor Lynn Loo, CEO of GCMD.

“In this case, guideline development is preceding actual commercial-scale operations, making it all the more important that these trials are as informative and comprehensive as possible so they can serve as a relevant reference for industry bodies in refining safe handling procedures, emergency response plans, and operational guidelines.”
