Marine fuel testing and marine surveying business Maritec Pte Ltd (CTI-Maritec) on Wednesday (27 July) issued an updated alert on the continued presence of chemical contaminants in ARA region bunkers, which are elevated potassium content and acid number.

Issued on 27 July, 2022

Since the last alert (BF202207-01) dated on 5 July 2022 on Chemical Contaminants in Fuels from ARA Region (Amsterdam, Rotterdam & Antwerp), CTI-Maritec has kept a close watch on the fuel quality in the region. More recently, several VLSFOs delivered in this region are still observed with the presence of chemical contaminants. These VLSFOs also indicated elevated potassium content and acid number.

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)

It is difficult to determine a safe concentration level suitable for marine diesel engine usage or the baseline wherein machinery problems may occur. Due to the severity of the machinery problems faced, we urge vessel operators to continue pre-emptively testing the fuels bunkered in the region by accredited test methods to detect these contaminants assessing the risk each bunker stem has on the vessel machinery.

Recommendation by CTI-Maritec:

  1. Obtain quality assurance and test proof from suppliers on the absence of contaminants in the intended stem prior bunker delivery (This will require testing beyond the scope of standard ASTM D7845-20 test method)
  2. Plan your bunkers well in advance to keep the incoming fuel segregated and reduce the risk of comingling.
  3. Ensure sampling procedure during bunkering is witnessed by both supplier and receiver and sample bottles are counter-sealed and same recorded in the Bunker Delivery Note.
  4. Be aware of your bunker supply contract and the notification time limit stipulated to flag potentially problematic fuels to the supplier.
  5. Look for signs of abnormally high potassium content (>110ppm) and/or high total acid number (>1.5mgkoh/g) and pre-emptively analyze the bunker fuel by Gas Chromatography and Mass Spectrometry (GC-MS) that can reveal the presence of undesirable compounds in the fuel thus safeguarding vessel operations.
  6. Where chemical compounds have been detected, gather sufficient evidence to support further investigation. Proceed to conduct joint analysis in agreement with the supplier by an independent laboratory capable of detecting the compounds to determine the compliance with ISO8217 clause 5 – General Requirements.

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

The Maritime and Port Authority of Singapore (MPA) and Republic Polytechnic (RP) have signed a Memorandum of Understanding (MoU) to establish a specialised Unmanned Aircraft (UA) Pilot Training programme for MPA UA pilots, which will also provide internship opportunities for RP students. 

This initiative aims to equip MPA, as well as commercial UA pilots, with advanced competencies to operate drones for maritime applications. These include inspection of vessel structures, monitoring of vessel emissions, and supporting emergency response efforts.

The course will cover essential skills, including take-off and landing from vessels, emergency procedures at sea, and Beyond Visual Line of Sight operations. UA pilots will also be trained to operate drones equipped with various sensor payloads such as electro-optics, infrared, and multispectral imaging. Tethered drone operations, which enable extended flight times for surveillance and monitoring, will also be included.

Under this five-year collaboration arrangement, MPA and RP plan to develop competency frameworks for UA pilots operating at sea, and will train over 20 MPA UA pilots annually. The collaboration will also explore the potential development of a maritime-specific qualification for UA pilots for interested parties. The training will be conducted by RP’s team of full-time lecturers who are also certified UA Pilot Licence trainers.

Through this partnership, RP students have internship opportunities with MPA, and can explore potential career pathways as UA pilots and watch supervisors coordinating the deployment of unmanned systems for port operations and maritime safety. 

RP lecturers and students will also have opportunities to gain industry exposure and practical experience through participation in MPA’s upcoming drone-related projects. In addition, RP will work with MPA in relevant committees and forums to shape policies, safety standards, and regulations for maritime drone operations.

In 2025, MPA will trial new drone capabilities, including coordinated drone operations for chemical spill management and the Maritime Drones Traffic Management System to ensure safety in port waters. 

The Maritime Drone Estate, launched in 2021, will also be expanded to support commercial drone services such as remote inspections and shore-to-ship deliveries. These advancements will contribute to safer, more fuel-efficient, and sustainable maritime operations.
