Bunker Fuel Sulphur Measurement

A new product from Parker Kittiwake– a fully hand Portable XRF  device (about the size of a bowling ball) that will analyse a 10ml (approximately) sample of fuel and give a lab quality Sulphur level to four decimal places within three minutes.  No reagents or accurate sample sizes required, and the push of one button will give you the answer you need. 

Samples can be taken at multiple intervals and if an anomaly is found, the supplier, broker, purchaser or vessel operator can respond immediately and take action before the vessel sails.  Switching fuel whilst underway can be carried out with confidence and if blending has to take place, a finite Sulphur level can be guaranteed. Bunker delivery notes can be verified by the purchaser and confidence can be restored.

As a Port State authority there has always been concern about how to police the new Sulphur cap, as surveyors would only be presented with historical data of what had been burned, or paper evidence of what is in the tanks*. If a surveyor has a Portable XRF device, samples can be taken immediately and it can be established whether the vessel should be subject to further investigation or ‘passed’ as meeting IMO regulations.

Why use the portable XRF Analyser?

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 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.
