INtegrity is a new suite of products designed to help the marine industry comply with MARPOL by providing quality assurance during bunkering and a Continuous Emissions Reporting System for use at the engines.


The principal benefit to users is the avoidance of financial risk.


INtegrity will be released shortly. If you would like to receive a brochure or be kept informed, send an email to Info@ViscoAnalyser.com.

INtegrity Applications:

Integrity has applications in a number of marine industry  operations. Follow the menu links to discover the benefits of INtegrity  in the following operations:

These applications are all based on the Integrity Principle.

The Importance of Fuel Quality:

Fuel quality is defined by measurements made in the laboratory. Laboratory analysis is recognised commercially, in dispute resolution and by legislation.

Fuel quality is defined for a range of properties, typically those defined by the ISO 8217 standards or as agreed by contract. The range of properties, the difficulties associated with their measurement online and the cost of these measurements together with the burden they place or would place on crew are all such as to place the burden of quality determination on the laboratory analysis.

Online measurement of quality is not commonly used and is not recognised or legitimised in any way.

The fuel quality is an unknown during many critical operations, or at least, it is only as good as the last laboratory analysis and since that analysis the fuel quality may have been compromised either deliberately or inadvertently, by a range of mechanisms commonly encountered in the management and transfer of fuel.

Until now the industry has accommodated the limitations of only knowing the fuel quality through the laboratory analysis but in today’s market the high cost of fuel and that for many operators it is the single biggest operating cost, or the second largest operating cost, and the advent of marine pollution legislation impacting on fuel quality, means that these limitations must be addressed.

The options are:

The continue as before or “do nothing” option is less and less tenable each day especially as it involves significant financial risks for suppliers and vessels. That means that sooner or later the industry will need or or be obliged to opt either for alternative measurement or the Integrity Solutions.

The Alternative Measurement option requires that critical parameters are measured online and not in the laboratory.  This would require a change in the legislation but more importantly, it means that each property of interest must be measured and such measurements may be individually, and certainly cumulatively, very expensive and may add to the crew burden.

They may also be vulnerable to misrepresenting the suitability of the fuel. For example, MARPOL requires an exact density and an exact sulphur content are reported. These may both now be measured online. However, supposing the fuel has an original sulphur content of 1.6% and is adulterated with water. When bunkered the density (used to account for the amount of fuel invoiced) will be higher and the sulphur content will be lower, sufficiently so as to appear to be suitable for use in a SECA. However, the fuel treatment system may remove most or all of the water before it reaches the engine. Thus the fuel being burnt will again have a sulphur content in excess of the permitted amount.

These problems are all resolved by the Integrity Solutions.


The Integrity Principle:

Integrity recognises that fuel quality is best determined in the laboratory.

The laboratory analysis reports on all fuel properties including the density at 15°C and the kinematic viscosity at 50°C and 100°C. These are both properties that can be easily and affordably measured online with a single instruments, the digital viscometer.

By measuring these two parameters in real time and continuously, they may be compared continuously to the values reported from the laboratory analysis.

If the density or the viscosity does not match the fuel certificate values, then the fuel quality has changed and the certificate is no longer valid.

Conversely:

If the density and the viscosity match the fuel certificate values then the fuel certificate is valid in all respects and for all properties.
