Bunker fuel testing and inspection

Fuel quality and quantity are important considerations during every bunkering operation.

Independent inspection and laboratory analysis can provide objective information about the fuel being delivered, helping stakeholders verify that the fuel meets the agreed specification and that the quantity transferred is appropriately documented.

Eurofins Maritime Services supports bunker fuel quality and inspection activities through laboratory testing and collaboration with experienced surveyors with local and international presence.

ISO 8217 bunker fuel testing

ISO 8217 specifies requirements for fuels for use in marine diesel engines and boilers. Testing against the applicable fuel specification can help assess whether a delivered marine fuel meets agreed quality requirements.

Eurofins provides bunker fuel quality testing aligned with applicable ISO 8217 requirements.

Testing can support:

• Verification of marine fuel quality
• Fuel purchasing specification checks
• Supplier and customer quality assurance
• Investigation of suspected off-specification fuel
• Fuel quality documentation
• Bunker fuel dispute investigations

The applicable testing parameters depend on the fuel grade, specification, contractual requirements and intended use.

Bunker fuel inspection services

Bunker fuel inspection combines physical inspection, sampling, documentation and laboratory analysis to provide a more complete assessment of a bunkering operation.

Eurofins Maritime Services works with surveyors with strong local and global presence to support inspection activities.

Services can include:

Vessel bunker quantity survey

Bunker Quantity Survey (BQS) can be performed in accordance with applicable procedures and standards, including:

• ISO 13739
• SS 600

Quantity surveying helps establish documented measurements associated with the quantity of fuel delivered during a bunkering operation.

Sampling and documentation

Proper sampling and documentation are important for reliable bunker fuel quality assessment.

Inspection activities can include:

• Bunker fuel sampling
• Sampling documentation
• Photographs where requested or permitted
• Documentation of relevant bunkering activities
• Sample handling for subsequent laboratory analysis

Representative sampling is particularly important because laboratory results depend on the quality and representativeness of the sample submitted for analysis.

Bunker fuel quality testing

Eurofins Maritime Servces provides laboratory analysis to assess marine fuel quality against applicable specifications.

Testing can support requirements under:

• ISO 8217
• MARPOL Annex VI
• Client fuel purchasing specifications
• Supplier specifications
• Other applicable marine fuel requirements

The analytical scope can be tailored according to the fuel type and purpose of the testing.

Fuel compatibility analysis

Different bunker fuels may have different chemical and physical characteristics. When incompatible fuels are mixed, problems can potentially arise within the vessel's fuel system.

Fuel compatibility analysis can help assess whether fuels are likely to be compatible when commingled.

Compatibility testing can be used to support:

• Bunkering decisions
• Fuel changeover planning
• Management of different fuel sources
• Investigation of fuel stability or sediment-related issues
• Assessment of potential compatibility concerns
• Compatibility analysis should be considered alongside the vessel's fuel management procedures and the characteristics of the individual fuels.

Forensic fuel oil investigations

Fuel-related problems can sometimes emerge after bunkering or during fuel use.

Eurofins Maritime Services provides forensic fuel oil investigation services to support the investigation of issues associated with marine fuels.

Investigations can be used to examine potential causes of:

• Abnormal engine performance
• Fuel system problems
• Fuel instability
• Excessive deposits or sludge
• Suspected contamination
• Fuel quality complaints
• Disputes relating to delivered fuel

Depending on the nature of the incident, laboratory analysis can be combined with information about the fuel, bunkering operation, sampling procedures and vessel operating conditions.

Why is independent bunker fuel testing important?

Independent fuel testing provides objective laboratory data that can help stakeholders assess whether delivered fuel meets the applicable specification.

For ship owners and operators, testing can help:

• Verify fuel quality before or after delivery
• Identify potential off-specification fuel
• Support fuel purchasing decisions
• Monitor fuel quality across suppliers and ports
• Investigate suspected contamination
• Support fuel compatibility assessments
• Provide analytical evidence for fuel-related investigations
• Support discussions and disputes between fuel buyers and suppliers

For fuel suppliers and other stakeholders, independent testing can provide documented analytical evidence of fuel quality.

Bunker fuel quantity and quality verification

Quality and quantity are two important aspects of bunker fuel delivery.

Quantity inspection focuses on determining and documenting the amount of fuel delivered.

Quality testing focuses on assessing the physical and chemical characteristics of the fuel against the applicable specification.

Combining inspection, representative sampling and laboratory analysis can provide a more comprehensive record of a bunkering operation.

Supporting MARPOL Annex VI requirements

Marine fuel quality is also subject to applicable environmental requirements under MARPOL Annex VI, including requirements relating to fuel oil sulphur content.

Eurofins Maritime Services bunker fuel testing can support monitoring of relevant fuel quality parameters where required by the applicable regulatory or contractual testing programme.

The specific requirements applicable to a vessel depend on factors including the fuel used, vessel operations and operating area.
