Optimizing Vessel Efficiency: The Low-Hanging Fruit
Operational efficiency is the cornerstone of profitability and sustainability in the maritime industry. Fuel costs constitute 50% - 70% of Operating Expenses (OPEX), making accurate fuel consumption measurement the most immediate and impactful area for improvement - the true "low-hanging fruit."
I. Fuel Consumption: The Basis for Profit & Compliance
Increasing crew awareness and knowledge of actual fuel consumption is key to validating improvement projects and new procedures. Our system provides the data required for:
Cost Reduction: Identify consumption fluctuations instantly to pinpoint and eliminate sources of waste.
Performance Benchmarking: Establish a precise baseline consumption to accurately gauge the benefit of performance-improving investments and maintenance (e.g., propeller cleaning).
Environmental Compliance: Documenting the vessel's primary source of emissions (fuel) via an automated system provides constant certainty of emission levels, critical for IMO CII and environmental reporting.
II. Why Marine Fuel Flow Meter Accuracy Matters (Coriolis vs. Volumetric)
Performance improvements directly correlate to fuel consumption reduction. Measurement accuracy is not negotiable when securing added profit from optimization.
Feature
Insatech Coriolis Mass Flow Meter System
Standard Volumetric Flow Meters
Accuracy
Better than 0.2% of nominal flow
Typically 0.5% to 2.0%
Measurement Type
Direct Mass Measurement (unaffected by temperature)
Volume-based, requires temperature-dependent conversion to calculate mass
Financial Impact
Highly precise data to secure savings.
Potential annual offset of up to 200 tons (USD 100,000 equivalent) on a typical vessel, due to slight misreads.
Financial Example: An offset of just 1% in measurement on a vessel consuming 100 tons per day for 200 days equals a loss of 200 tons of fuel per year - a significant uncaptured profit.
III. Know When You Make Money - And Make More!
Without high-accuracy measurement, it is truly difficult to quantify the ROI of procedural changes, new installations, or maintenance.
By installing our Fuel Consumption System, you immediately:
Eliminate Uncertainty: Move beyond less reliable data sources like noon reports or low-accuracy instrumentation to achieve timely, verifiable proof of fuel-saving projects.
Increase Crew Focus & Competitive Advantage: Free your crew from the operation and maintenance of complex instruments, allowing them to focus on their primary task: optimizing the ship's efficiency and increasing profits.
The Fuel Consumption System can be seamlessly upgraded to the comprehensive Performance Monitoring System for deeper analysis and operational intelligence.
The Marine Fuel Consumption System: Functionality & Data Leverage
The Insatech Fuel Consumption System utilizes high-accuracy mass flow meters to measure, collect, and process crucial fuel data. This automated process transforms raw consumption figures into actionable intelligence for your crew and shore office, driving operational efficiency, maintenance planning, and regulatory compliance.
I. How the System Works: Real-Time, Direct Measurement
The core principle involves the precise differential measurement of fuel flow to key consumers.
Technology: The system deploys Coriolis Mass Flow Meters strategically on the engine supply and return lines, or across other consumers (generators, boilers).
Measurement Principle: By measuring the flow of fuel before and after the engine/generator, the system calculates the exact consumption, free from temperature or volume fluctuations.
Direct Efficiency Calculation: Consumption data is correlated in real-time with external measurements like speed log and GPS signals to provide a direct calculation of fuel efficiency (e.g., grams/ton-mile).
Scalability: The system is customizable. Install flow meters per major consumer or a single set for the vessel's total consumption, depending on the required level of diagnostic insight.
II. Seamless Data Access & Shore Integration
We ensure your crew and headquarters have easy, reliable access to the measured data, regardless of connectivity.

III. Making the Data Work for You: Key Applications
The processed consumption data is the foundation for a range of critical operational and commercial activities. Use this data to achieve a competitive edge:
Operational Optimization: Test and validate trim tools and other physical adjustments to find the most efficient operational setting.
Compliance & Management: Implement and maintain your SEEMP (Ship Energy Efficiency Management Plan) with verifiable data.
Performance Evaluation:
Monitor and improve your current CII rating.
Create KPI’s (Key Performance Indicators) for each voyage and vessel.
Evaluate improvement projects (e.g., retrofits, hull coatings) before rolling them out fleet-wide.
Maintenance Planning: Monitor the ship’s consumption trend over time to proactively identify degradation (e.g., fouling, engine wear) and improve predictive maintenance scheduling.
Crew Empowerment: Provide the crew with instant, clear data insight to increase operational awareness and foster a culture of efficiency.
Upgrade Path: The Marine Fuel Consumption System is the core foundation and can be easily upgraded to the advanced Performance Monitoring System for deeper analytics.
DataLink is an optional feature that automatically transfers the data collected on board to your own or a third-party database. This happens whenever an internet connection is established, and data validation ensures that no data is lost in the process. If no connection is available, the vessels database will just save the data locally, until the connection is reestablished.
Our systems collect a minimum of data which can be transferred on even the most challenging satellite internet connection furthermore DataLink checks the shore database for the latest data available and only transfers the new data further minimizing the amount of data that needs to be transferred.

The display of the main engine overview provides a total view of the main engine’s fuel consumption. A consumption trend line shows an accumulation of the most recent data. The setup is dependent on the number of installed meters.
Main Engine
If you want a more detailed view, simply select a main engine from the overview screen. From here it is possible to get the actual and total consumption of the given engine, as well as values for engine inlet and outlet such as mass flow, volume, density, temperature and total mass.
Auxiliary Engine Overview
From the Aux engine screen you get an overview of all your auxiliary engines’ consumption. As with the main engine overview, this also provides an easy to read display of consumptions, trends and engine loads.
Service Parameters
The service parameters displays raw data for each flow meter related to consumers. It shows the main menu data and provides the possibility for a manual totalizer. From here the alarm status screens are setup. Furthermore the green light shows that the communication between flow meter and system is intact.
Installation setups
1-meter setup
The simplest way of measuring fuel consumption is by installing a single flow meter, which measures the fuel transferred from the fuel tank to the settling tank. The level of fuel in the settling tank is typically maintained by level sensors, and therefore the flow to the settling tank is equal to what is consumed.
3-meter setup
If more detailed monitoring is desired, then a 3-meter setup can be introduced. With the 3-meter system, the total fuel consumption is monitored by flow from fuel tank to settling tank. A set of flow meters, installed on the common auxiliary fuel supply line and return line, will provide the total consumption measurement of the auxiliary engines. By subtraction, the main engine fuel consumption can be calculated. By splitting the main engine and the auxiliary engines, the crew on board as well as on shore has a much more detailed overview of how the consumers perform.
Full consumer insight
To gain full understanding of the fuel consumption, you measure on each consumer inlet and outlet. This will provide a complete insight into each consumer’s fuel consumption, and any deviations from performance expectations or norms, can easily be pinpointed. This can potentially aid in preventative maintenance planning and better utilisation of auxiliary engines.
Your own setup
Insatech Marine is not restricted regarding installations. Therefore if you have your own specific setup that you would prefer, we can accommodate a corresponding setup or install the system on existing flow meters. In such cases we will typically include an engine pre-inspection to ensure technical feasibility of the setup.
