Fuel Analysis

Marine fuel quality directly affects engine reliability, regulatory compliance, and operational safety. Fuel testing at bunkering and during storage helps verify specification compliance and detect contamination before it reaches injection systems. ORDNEX coordinates fuel sampling and analysis through qualified UAE-based laboratory partners.

PURPOSE & ENGINEERING VALUE

Why Fuel Analysis Matters

Off-specification fuel is a significant cause of main engine damage, injection system failures, and regulatory penalties. Cat fines, water contamination, and flash point violations present direct risks to vessel safety and engine integrity.

Testing fuel at the point of bunkering provides evidence for any quality dispute and confirms MARPOL sulphur compliance before the fuel enters the bunker tank.

Typical Sampling Points

·Bunkering hose (during delivery)
·Storage tank (before use)
·Service tank (in-use monitoring)
·Settling tank (pre-purification check)
·Fuel oil unit inlet (final system check)

Typical Report Turnaround

24 to 48 hours for standard distillate and residual fuel analysis panels.

ORDNEX coordinates testing through qualified laboratory partners. Turnaround times are subject to laboratory capacity and sample condition.

TEST PARAMETERS

Analysis Parameters & Interpretation

Density at 15°CConfirms fuel grade and helps detect adulteration. Density affects fuel injection timing and combustion efficiency.

Kinematic Viscosity at 50°CDetermines pumpability and atomisation quality. Out-of-specification viscosity causes injection system wear or fuel pump failure.

Flash PointSafety-critical parameter. Flash point below minimum specification (60°C for marine distillates) indicates dangerous contamination with low flash point products.

Water ContentFree water causes injector corrosion, microbial growth, and fuel filter blocking. Detection prevents serious engine damage.

Sulphur ContentRegulatory compliance under MARPOL Annex VI (0.1% ECA, 0.5% global cap). Excess sulphur damages engine components and increases scrubber load.

Total SedimentMeasures sludge and asphaltene content in heavy fuel oils. High sediment blocks filters and damages injection equipment.

CCAI (Calculated Carbon Aromaticity Index)Predicts the ignition quality of residual marine fuel. High CCAI values indicate poor ignition properties, risking misfiring and engine damage.

Cat Fines (Al + Si)Catalytic fines from refinery processes cause severe cylinder liner and piston ring abrasion. Critical measurement for residual fuel users.
