Optimization of Fuel Measurement at Christiania Shipping

Accurate fuel measurement is critical for marine operators. Fuel represents a major share of vessel operating expenses, and even minor measurement inaccuracies can lead to significant financial impact over time.

Christiania Shipping approached Insatech with a clear challenge: their existing fuel measurement setup did not provide sufficiently reliable data to support fuel optimization and performance monitoring. The system was sensitive to density changes, temperature fluctuations, and recirculation in the engine return line. As a result, fuel consumption could not be calculated with confidence.

The Challenge: Uncertain Fuel Consumption

The vessel operated with a conventional flow measurement principle that struggled under real marine conditions. Pump pulsation, varying fuel properties, and limited installation space in the engine room further complicated the situation.

Without precise mass-based measurement, the operator lacked:

• Reliable documentation of actual fuel consumption
• Visibility into engine performance trends
• A solid foundation for fuel efficiency improvements
• Data-driven control of operating expenses

Christiania needed a robust and repeatable solution suitable for marine environments and scalable across similar vessels.

The Solution: Mass Flow Measurement on Supply and Return Line

Insatech implemented a high-accuracy Coriolis mass flow solution, installing flow meters from Yokogawa on both the fuel supply and return lines.

By measuring true mass flow rather than volume, the system eliminates the influence of density and temperature variations. This enables accurate calculation of engine fuel consumption under all operating conditions.

The installation was engineered to withstand vibration and space constraints in the engine room while ensuring stable flow conditions and long-term measurement repeatability.

The Result: Transparency and Fuel Optimization

After commissioning, the operator gained immediate improvements in fuel transparency and control.

The upgraded system now delivers:

• Precise fuel consumption measurement
• Improved marine fuel efficiency
• Reliable data for vessel performance monitoring
• Stronger control of fuel-related operating expense

With accurate and repeatable measurement, fuel consumption is no longer an estimate - it is a verified performance parameter.

A Repeatable Marine Application

Fuel measurement uncertainty is common across commercial fleets. This application demonstrates how mass flow technology provides a scalable and robust solution for marine fuel optimization.

By upgrading to accurate mass flow measurement, marine operators can strengthen operational efficiency, reduce fuel costs, and support long-term performance improvement initiatives.
