Version 2.1.0

Release Date: 08-Jan-2025

Overview

We are thrilled to introduce version 2.1.0 of our web application. This version delivers changes to UI and features for the home page, as well as an all new revamped chatbot.

New Features

1. DRUMS Home Page

Notification Rail System

New Notification Rail: A dedicated notification rail now appears on the right side of each vessel card whenever there are active alerts. The rail updates live as new alerts are detected by DRUMS. Users can acknowledge alerts directly from the rail using the tick/check button.
Grouped Alerts: Repeat or ongoing alerts are automatically merged into a single card, preventing the rail from being filled with identical entries.

Engine Gauges System

Dynamic Engine Display: The gauge panel adapts automatically to each vessel’s actual engine configuration. It shows real-time power output from 0 to 100 percent, with a smooth green-gradient scale that makes higher loads instantly visible through darker shading. This layout supports 3-engine vessels, 2-engine vessels (Port/Stbd), and future custom configurations.
Real-Time Data Integration: Gauges pull the latest load, temperature, and timestamp data directly from the unified readings helper. Readings update smoothly and consistently across the entire DRUMS interface.

Running Hours Readings

Adaptive Running Hours Panels: Monthly, yearly, and total running hour readings are displayed. The running hour tabs match each vessel’s exact engine count and naming, and everything renders dynamically based on real vessel data.
Accurate, Synced Values: Running hours pull from the same gold table logic used by gauges and alerts, ensuring all data stays perfectly aligned.

Backend Enhancements

Real-Time Updates: Updates happen through backend triggers that sync new readings the moment they're recorded, ensuring the gauges always reflect the most recent engine data.
Cleaner Database Structure: Removed conflicting unique keys and fixed constraints that previously caused duplicate-row issues. Simplified indexing ensures faster lookups for active incidents and recent readings.

2. DRUMS Monthly Reports

AI-Enhanced Monthly Reporting: DRUMS Monthly Reports produces AI-enhanced PDF reports with operational insights and troubleshooting recommendations for every vessel.
Clear, Professional Monthly Reports: Receive a polished PDF each month with an executive summary, KPIs, operating profile, alarms, sensor insights, trends, and baseline comparisons across all vessel engines.
Simplified Trend Analysis: Trends are presented in a clean two-column layout with four charts per page, consistent sizing, and clearer legends, making it faster to spot patterns and abnormalities.
At-A-Glance Alert Overview: A consolidated alert summary shows NORMAL, CAUTION, WARNING, and CRITICAL counts per generator, enabling faster prioritization of issues.
Earlier Fault Detection: Automatic identification of abnormal cylinder temperature deviations helps highlight developing engine issues before they escalate.

3. DRUMS Maintenance Records

Create Maintenance Entries: Log any maintenance activity directly from the platform — including type, title, description, running hours, and more.
Author Tracking: Every entry clearly shows who created it for easy follow-up and accountability.
Integrated Notifications: Create a record directly from a notification to connect maintenance actions with system alerts.
Secure Access Control: Users can only create maintenance entries for vessels they have permission to access.

4. Chatbot Version 2.1.0

Performance & Visualization

High-Performance Visualization Engine: Migrated to Apache ECharts, reducing chart render times from 60-120 seconds to 4-5 seconds for large datasets with 100,000+ datapoints.
Optimized Database Architecture: Implemented silver table layer providing 19x speedup for multi-engine historical queries.
Sub-5 Second Query Performance: All real-time and historical queries now complete in under 5 seconds, ensuring rapid insights for marine operations.

Intelligence & Automation

Multi-Engine Intelligence: Automatic querying across all engines when ship is selected, eliminating manual engine selection and providing comprehensive fleet-level insights.
Real-Time Streaming Responses: Server-sent events deliver live AI responses as they generate, improving user experience and reducing perceived wait times.
Maintenance Manual Integration: Fully implemented RAG system with 316 indexed maintenance manual chunks, providing context-aware troubleshooting guidance and recommendations based on engine documentation.

User Experience

Advanced Multi-Axis Charts: Intelligent automatic grouping of sensors by measurement units with coordinated color palettes for marine engineering data.
Interactive Visualization Controls: Enhanced chart interactivity with zoom, pan, data range selection, reset, and PNG export functionality.
Large Dataset Handling: LTTB sampling algorithm enables smooth visualization of extensive historical data without performance degradation.

System Reliability

Query Optimization: Database query deduplication and precise sensor matching for improved system efficiency.
Enhanced Session Management: Extended timeout to 30 minutes for complex analysis workflows with improved context retention.
Robust Error Handling: Advanced error segregation ensures partial sensor failures don't disrupt entire queries
