Bunker Flash: High cat fines found at Singapore ports, alerts Maritec-Naias

Maritec-Naias tested forty samples representing VLSFO bunker fuel deliveries from various suppliers at Singapore ports, which indicated Al+Si concentrations ranging from 51 mg/Kg up to 120 mg/kg.

Bunker fuel testing and marine surveying business Maritec-Naias on Thursday (7 August) issued an alert regarding high levels of Aluminium + Silicon (Al+Si) found after conducting testing on VLSFO samples from Singapore ports:

FINDINGS & INSIGHTS

During the period of 25 July 2025 to 02 August 2025, Maritec Pte Ltd (hereafter referred to as Maritec-Naias) tested forty samples representing VLSFO deliveries from various suppliers at Singapore ports, which indicated Aluminium and Silicon (Al+Si) concentrations ranging from 51 mg/Kg up to 120 mg/kg. 

Maritec-Naias findings of Al+Si concentrations in the forty samples tested were as follows:

  • Two samples indicated Al+Si concentrations above 100 mg/Kg levels
  • Eleven samples indicated Al+Si concentrations above 60 mg/Kg levels
  • Twenty-nine samples indicated Al+Si concentrations between 51 to 60 mg/Kg levels

While Al+Si levels of thirty eight out of forty samples fell within the specifications of ISO8217:2005 (80 ppm) and even within the ISO8217:2010/2017 specifications (including permitted limits of 72 PPM as per ISO4259 for a single test result), the Catfines content can still be considered at high levels.

Aluminium and Silicon are main classes of abrasive solids found in fuels. High levels of abrasive particles at the engine inlet may lead to abnormal wear and tear of the fuel system components, piston rings and cylinder liners. In fact, to control the amount of catalyst fines delivered to the engine, many engine builders specify a maximum limit of 15 mg/kg of Aluminium plus Silicon at the engine inlet.

An efficiently operating fuel purification system is the preliminary method of removing these particles. Measuring the fuel’s Aluminium and Silicon concentrations before and after the system’s centrifuge provides an indication of the efficiency of the purification system in removing catalyst fines.

OUR RECOMMENDATIONS

Maritec-Naias recommends collecting samples from within the fuel system at points such as the fuel oil tank transfer pump, before and after centrifuge, service tank and after filter samples to check the fuel cleaning efficiency.

Maritec-Naias states, while all presented findings are true, this document, does not reflect on the overall quality of fuel being supplied in the Singapore region. If you intend to bunker at this region please request a Certificate of Quality prior to loading.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
