Introduction
This document outlines the Speed and Consumption Performance solution developed by Gelectric. The primary objective of this solution is to provide a precise, data-driven understanding of the relationship between vessel speed, fuel burn, and environmental conditions. By utilizing the Automated Data Catcher to extract historical and real-time operational data, we enable ship owners to validate performance warranties, optimize voyage speeds, and reduce total fuel expenditure.
Background
The "Speed-Consumption Curve" is the heartbeat of maritime economics. However, a vessel’s actual performance at sea rarely matches the theoretical curves established during sea trials. Factors such as hull aging, engine wear, and varying weather conditions constantly shift the efficiency baseline. Traditionally, analyzing these shifts requires manually pulling data from thousands of Noon Reports, a process so slow that by the time a performance dip is identified, thousands of dollars in excess fuel have already been burned.
Problem Statement
The primary challenges in managing speed and consumption performance include:
Manual Analysis Fatigue: Manually correlating speed, fuel consumption, and weather from unstructured PDFs is too slow for active voyage optimization.
Performance Disputes: Conflicts between owners and charterers often arise due to "under-performance" claims that lack a structured data foundation to resolve.
Weather Blindness: Failing to accurately account for the impact of wind and waves when evaluating engine efficiency.
Static Decision Making: Relying on outdated sea-trial data instead of the vessel's current "real-world" performance profile.
Objectives
The primary objectives of this solution:
To automate the extraction of speed, fuel, and engine RPM data from unstructured sources using the Automated Data Catcher.
To generate real-time Speed-Consumption curves based on current hull and engine conditions.
To provide objective data for defending or settling Charter Party (C/P) performance claims.
To identify the "Sweet Spot" (optimal speed) for every voyage to maximize profit margins.
To monitor the rate of performance degradation to optimize hull cleaning schedules.
Solution
Automated Data Catcher for Performance Analytics
To address these challenges, Gelectric’s solution creates a dynamic performance model by unlocking technical data:
High-Frequency Data Extraction: Ingesting daily Noon Reports and Engine Logs to build a continuous performance timeline.
Automated Normalization: Adjusting speed and consumption data against Beaufort scale and sea state to reveal the "True" performance of the vessel.
Warranty Cross-Referencing: Automatically comparing extracted speed and consumption figures against Charter Party limits.
Engine-Hull Correlation: Linking fuel flow increases to specific engine parameters or suspected hull fouling.
Key Data Points Captured
Speed Over Ground (SOG) vs. Speed Through Water (STW) Extracting various speed metrics to analyze the impact of currents and weather on fuel efficiency. Source: Deck Logs & AIS Data.
Specific Fuel Oil Consumption (SFOC) at Various Loads Recording fuel flow at different RPM intervals to map the engine's current efficiency curve. Source: Engine Room Logs & Flow Meter Records.

Slip & Propeller Efficiency Extracting propeller pitch and engine RPM to calculate "Slip," a key indicator of hull cleanliness. Source: Technical Noon Reports.
Data Collection and Analysis
Following the activation of the Automated Data Catcher, technical and commercial managers gain access to:
Dynamic Performance Curves: Real-time visualizations showing the vessel's current speed-consumption reality vs. its "as-built" design.
C/P Performance Alerts: Automated notifications when a vessel is in danger of breaching its speed or consumption warranties.
Optimal Speed Recommendations: Data-driven guidance on the most efficient speed for a given leg, considering current fuel prices and arrival windows.
Hull Fouling ROI Analysis: Calculating the exact daily cost of hull resistance to determine the optimal timing for a diver inspection or cleaning.
Conclusion
The Gelectric Automated Data Catcher transforms vessel performance from a theoretical exercise into an exact science. By automating the collection and structuring of speed and consumption data, we provide the transparency needed to protect commercial interests and maximize operational margins. In a high-cost, low-margin environment, knowing your vessel's true performance is the ultimate competitive advantage.
