Meeting New Sulphur Limits for Marine Fuel Oil

Meeting New Sulfur Limits for Marine Fuel Oil - Engine close up - Parker Kittiwake

The ability to spot check the Sulphur content of fuel oil onboard a ship will help shipowners and operators ensure compliance with the latest IMO (MARPOL) regulations.

From January 2020 the maximum allowable Sulphur content of marine fuels is changing: for all areas outside the existing Sulphur Emission Control Areas (SECAs) the limit will be reduced from the current level of 3.50% m/m to just 0.50% m/m. Introduced by the International Maritime Organization (IMO), the new limit is being applied worldwide and covers the fuel oils used in main and auxiliary engines as well as in boilers. Compliance with the new regulations will be monitored by Port State Control.

For shipowners and operators, the new limit leaves little room for error. The traditional method of Sulphur level confirmation by Bunker delivery note significantly increases the risk of non-compliance and subsequent penalties, furthermore waiting for laboratory analysis is equally flawed as the vessel could have sailed by the time that is received and the Sulphur level found to be outside the specified limit. With this new equipment, bunkers can be sampled during delivery and noncompliance could be identified in the first few minutes of delivery (and at any other time interval) thereby preventing expensive de-bunkering and payment for non-compliant fuel.

"The fuel variation from port to port will be vast and furthermore, at present, fines and penalties imposed on non-compliant vessels in the special environmental control areas vary considerably. As such, ensuring uniformity in enforcement poses a hurdle."

Scott Herring, marine account manager, Parker Kittiwake

It will be essential for each vessel to know and comply with Sulphur limits of 0.10% m/m in SECAs or 0.50% m/m in all other areas worldwide. On-Board testing is one of the most effective means of establishing fuel compliance with Sulphur regulations.

 

Testing at sea, offshore or on land

Meeting New Sulfur Limits for Marine Fuel Oil - top view of marine engine roomAs a lightweight, portable and self-contained X-Ray Fluorescence (XRF) spectrometer, the XRF Analyser enables in-situ lab standard testing of fuel oils at sea or on land.  The XRF provides an accurate indication of sulphur content through the analysis of a small fuel sample in less than three minutes. This gives both shipowners and Port State Control (PSC) the ability to conduct laboratory-standard testing onsite, before non-compliant fuel is bunkered and before a vessel carrying non-compliant fuel leaves port.

The XRF Analyser can, for example, be used in the engine room or control room of a ship to test the Sulphur content of fuel oil as it is being delivered. Checking the fuel during delivery allowing ships personnel to verify that the Sulphur content shown on the bunker delivery note is correct, thus eliminating the risk of accidental non-compliance.

The XRF can be used by suppliers, brokers, surveyors and producers of bunker fuels. Faster and more accessible testing means that the XRF Analyser allows fuel oils to be tested more frequently and conveniently compared to sending samples to a laboratory. By allowing test results to be downloaded, or storing them for up to two years, the XRF Analyser also plays an important role in helping vessel operators to manage compliance audits more efficiently.

Traditional methods for confirming compliance with sulphur limits rely on paperwork requirements such as the Bunker Delivery Note (BDN). This not only significantly increases the risk of non-compliance and subsequent penalties for shipowners, but also heightens the environmental impact of burning fuel with a higher sulphur content. In addition, the delay incurred by laboratory analysis creates the risk that the vessel may have left port with non-compliant fuel onboard, or may require non-compliant fuel to be de-bunkered and compliant fuel re-bunkered, incurring significant delays and additional cost. The XRF Analyser provides a spot-check analysis of the sulphur content in fuel on site, allowing PSC to ascertain compliance almost instantly, and affording shipowners the opportunity to avoid fines, plus the time, expense and operational impact of bunkering non-compliant fuel.

“The XRF Analyser is factory calibrated according to ISO 8754 and makes field measurements that correlate strongly with ISO 8754 laboratory measurements."
Dr. David Atkinson - Principal Chemist

 

Measure lube oil performance and accelerated wear

In addition to measuring the Sulphur content in fuel oils, the XRF Analyser can be used to measure a range of other elements that are common contaminants which can affect lube oil performance and indicate accelerated wear conditions. Wear elements measured by the Parker Kittiwake XRF Analyser and their likely sources on board a ship (if any):

The XRF Analyser combines simplicity with accuracy. Its standalone operation means that it offers immediate plug-and-play operation. Integrated into the small, lightweight housing is a high-resolution LCD touch-screen display which enables fast operation and delivers clear results.

The operator simply draws the sample of fuel oil from the ship’s system into the sample container, places it in the XRF Analyser and presses the test button. As the sample is not damaged or altered during testing, it can be retained for any additional sample analysis. 

The result of the test is displayed the percentage of Sulphur in the sample. This helps to avoid ambiguity and human error by eliminating the need for the operator to interpret the test data. 

 

A proven partner

The XRF Analyser is part of Parker Kittiwake’s range of condition-monitoring
equipment. This equipment is used where maximum efficiency and total confidence are vital in protecting capital plant and equipment. Our equipment is used extensively throughout the Marine, oil and gas, energy generation, aviation and industrial sectors.
