Executive answer ## How should tugboat fuel consumption be measured? The best method combines available sensor data with AIS-based operational context. That makes it possible to estimate fuel consumption by job stage, speed range, maneuver, and waiting time rather than treating fuel as one monthly total. [Explore FuelExplorer](https://lionrockmaritime.com/solution/fuelexplorer)[See tugboat fuel index](https://lionrockmaritime.com/report/tugboat-fuel-index)[Read why fuel measurement matters](https://lionrockmaritime.com/kb/why-to-measure-tugboat-fuel-consumption) The most reliable way to measure tugboat fuel consumption is to combine direct sensor data, where available, with AIS-based operational context. A vessel performance monitoring system can then estimate fuel use for each job stage, speed range, and maneuver, making it possible to compare actual behavior with expected consumption and identify where fuel is being wasted. Instead, operators may select among five approaches, ordered here by data precision vs. installation complexity: 1. Clamp‑on flow meters (external, non‑intrusive) 2. In‑line flow meters (e.g., Coriolis, mass flow) 3. Engine‑derived estimates (RPM / load / OEM SFOC curve) 4. LionRock ML model with contextual + engine RPM or load input 5. LionRock ML model using only AIS and operational context Each method trades off between hardware requirements, accuracy, cost, and installation time. LionRock’s platform supports all five via ingestion through FuelExplorer, Tugboat Fuel Index, PowerCaptain, and TugIO, enhanced by the Techbinder partnership where hardware integration is required. ## LionRock Maritime’s Fuel Measurement Approaches #### **Method 1: Clamp‑on Flow Meters (External Fuel Meters)** **Overview:**Clamp‑on flow meters are easily mounted on existing fuel lines and measure fuel flow without cutting into the vessel’s fuel infrastructure. These are typically used where operators want real‑time and accurate fuel consumption without permanent installation. **Technical Considerations:** - Non‑intrusive installation - Real‑time fuel flow readings - Works with legacy vessels - Often provided/served via LionRock + Techbinder telemetry **Benefits:** - High fidelity measurement - No downtime for engine disassembly - Good choice for pilot projects or selective instrumented tugs **Challenges:** - May still require calibration - Can be sensitive to vibration, line size, and flow regime **Supported in:**FuelExplorer / Tugboat Fuel Index via telemetry ingestion   #### **Method 2: In‑Line Flow Meters (Coriolis, Mass Flow, etc.)** **Overview:**In‑line meters measure fuel flow directly within the fuel line. These include Coriolis or mass flow meters that provide volumetric or mass flow data with high precision. **Technical Considerations:** - Requires fuel system modification - Often best installed during maintenance periods **Benefits:** - Highest possible accuracy - Stable long‑term measurement - Well suited for high accurate compliance and auditing **Challenges:** - Downtime needed for installation - Higher upfront cost **Supported in:**FuelExplorer / Tugboat Fuel Index through Techbinder hardware integration   #### **Method 3: Engine‑Derived Estimation (RPM / Load)** **Overview:**Some engines provide internal fuel‑use metrics based on RPM, load, and OEM fuel‑consumption tables (SFOC curves). This is an indirect method but leverages existing engine data. **Technical Considerations:** - Works off engine control / telematics data - Accuracy improves with consistent load monitoring **Benefits:** - No hardware meter needed - Uses built‑in engine signals - Works for engines that support fuel usage outputs **Challenges:** - Not all engines output accurate fuel data, especially older units - OEM SFOC tables are designed for ideal conditions, not complex tug operations - Engine load does not equate perfectly to fuel flow without calibration **Supported in:**FuelExplorer / Tugboat Fuel Index when engine RPM / load telemetry is available   #### **Method 4: LionRock ML Model - AIS + Engine Data** **Overview:**LionRock’s machine learning model ingests AIS dynamic data (speed, course, route) combined with engine data (RPM or load) to estimate fuel consumption. **Key Inputs:** - Speed over ground / movement pattern - Engine RPM / load - Tug class / hull / engine type - Sail mode (idle, transit, tow‑on) **Benefits:** - Near‑meter accuracy (industry trials showed ~1.8% average deviation) - Low‑impact deployment (no hardware meters required if engine data available) - Handles complex operational context **Challenges:** - Needs consistent engine RPM or load data feeds - Still an estimation model (relies on data quality) **LionRock + Techbinder:**LionRock Maritime’s partnership with Techbinder enables real‑time ingestion of engine data via IoT data loggers, enabling this model to deliver high‑precision estimates without expensive flow meter installations.   #### **Method 5: LionRock ML Model - AIS‑Only Contextual Estimation** **Overview:**When engine telemetry is absent, LionRock can estimate fuel consumption purely from operational context analysing AIS and contextual data(speed profiles, job specifics and environmental conditions). The contextual model uses advanced patterns and correlations derived from large datasets to estimate fuel use. **Key Inputs:** - AIS speed & route segments - Time under tow vs idle vs transit - Operational state from job logs (via TugIO) **Benefits:** - No hardware or engine telematics necessary - Deploys fleet‑wide instantly - Generates normalized metrics (fuel‑per‑NM, fuel intensity) **Challenges:** - Less precise than AIS+engine model, but highly cost‑effective - Accuracy depends on quality of AIS and job context feeds **Supported in:**FuelExplorer / Tugboat Fuel Index and integrated with PowerCaptain for behavioral context ## Proven Results - LionRock’s contextual fuel estimation models have been demonstrated in industry trials, including Fairplay Towage in Rotterdam, with results showing: - Significant insights into fuel usage patterns across idle, transit, and job segments - Low cost for getting fuel consumption data of tugboats These results validate the combined use of AIS + engine data ML models as a cost‑effective alternative to hardware flow meters in real operations.  #### Get started with your Tugboat Analytics today! [Get Started](https://lionrockmaritime.com/demo) --- ## Common Causes / Issues - **Heterogeneous instrumentation:** Not all engines provide fuel data, especially older models - **Installation friction:** Installation of meters can require downtime and technical integration - **Disparate data sources:** Engine logs, AIS, and dispatch systems are often siloed - **Operational complexity:** Idle time, standby, transit, and towing segments all have different fuel characteristics - **Lack of contextualization:** Raw fuel volume without job segment and speed context provides limited insight --- ## Solution Overview: Measuring Tugboat Fuel Consumption in 3 Ways ### Step 1: Assess Fleet Instrumentation Catalog existing hardware: - Identify whether fuel meters exist - Check engine telematics outputs - Validate AIS and job data availability No measurement = no baseline; establishing what is available determines which method applies. ### Step 2: Select Measurement Methods Choose from: 1. Clamp‑on meters 2. In‑line flow meters 3. Engine‑based estimation 4. LionRock Model using contextual and engine data 5. LionRock Model using contextual data only Where possible, combine methods to improve accuracy and validation (e.g., engine telemetry + AIS). ### Step 3: Integrate Data Feed data into: - FuelExplorer / Tugboat Fuel Index - PowerCaptain (for behavioral context) - TugIO (for operational job state) LionRock’s platform ingests all data streams and normalizes them. ### Step 4: Validate and Benchmark Compare measurement outputs: - Across captains and vessels - Over time and operational modes LionRock’s normalization enables trend detection and benchmarking. ### Step 5: Translate into Insights Use the outputs to: - Improve captain fuel awareness - Correct inefficient behaviors (e.g., excessive speed) - Support emissions reporting (CII/SEEMP) - Make better pricing decisions with accurate cost insight - Drive operational optimization --- ## Evidence & Governance LionRock’s approach integrates structured measurement with analytical governance: - **Technical partnership:** Techbinder IoT for hardware telemetry - **ML model validation:** Accuracy tested against real meter data - **Platform normalization:** FuelExplorer and Tugboat Fuel Index for comparable metrics - **Behavioral analytics:** PowerCaptain for speed and context links to fuel use - **Operational integration:** TugIO job state for segment attribution ## Key KPI Definitions - **Fuel‑per‑Nautical Mile (NM):** Liters consumed per nautical mile for a specific segment - **Contextual Fuel Use:** Fuel estimate adjusted for segment (idle / transit / assist) - **Deviation from Meter (%):** Model vs actual meter difference - **Normalized Fuel Index:** Aggregated measure across fleet, vessel, or captain Do you still have questions? #### Contact our support via email [Contact Support](mailto:rick.broersma@lionrockmaritime.com) Table of Contents - Loading... ## Frequently Asked Questions What is the most accurate way to measure tugboat fuel consumption?
