LOTUS – Powering smarter fleets with real-time oil condition intelligence

The Lube Oil Testing Unit for Ships (LOTUS) enables continuous, inline oil condition monitoring, detecting contamination, degradation, and wear debris in real-time enables data-driven maintenance and augments asset integrity.

Traditional lube oil testing is reactive, inconsistent, and labor-intensive

Conventional oil testing depends on manual sampling and shore-based analysis, which is time-consuming, often inconsistent due to sampling errors, and reactive by nature. This delay in diagnosis leads to missed warnings, unplanned machinery failures, and inefficient oil change schedules—each potentially costing thousands of dollars per incident.

LOTUS is an inline, automated oil condition monitoring system designed to detect real-time changes in oil health directly within the lubrication system. By continuously tracking degradation trends and contamination events—including water in oil, fuel dilution, soot, and wear debris—LOTUS allows operators to act before damage occurs. It transforms oil monitoring from a manual task to an automated, data-rich, predictive maintenance tool.

Advanced inline sensing + smart software for proactive maintenance

LOTUS, coupled with ASTER – SENSYN’s proprietary data analytics software, provides precise inline fluid sensing data, actionable alerts, and fleet-wide visibility—making maintenance smarter, safer, and significantly more efficient.

Built for marine conditions Withstands harsh operating environments—high temperatures, vibration, and oil pressure.

Inline, continuous sensing Real-time monitoring of oil quality eliminates sampling delays and human error.

Multi-parameter detection Measures viscosity, Total Base Number (TBN), water content, soot, fuel dilution, and ferrous/non-ferrous wear particles.

Real-time alerts and diagnostics ASTER triggers alerts when thresholds are breached, aiding rapid crew response.

Predictive insights with trend analytics ASTER learns from patterns to forecast degradation and flag machinery risks early.

Cross-equipment compatibility Although primarily aimed at Main Engine and Aux Engines, LOTUS is applicable onto purifier systems, gear oils as well as stern tube oil monitoring.

System integration Interfaces with vessel AMS and digital platforms.

Cloud-ready with offline flexibility Syncs data to cloud for shore access or operates standalone with onboard visualization.

Transform oil into a decision-making tool—optimize maintenance, minimize risk

LOTUS plus ASTER deliver continuous insights to eliminate failures, extend oil and engine life, and enable smarter fleet decisions.

Ensure asset integrity Detect wear and contamination early to protect engines and critical components.

Reduce crew workload Fully automated monitoring and reporting free up engineering time for higher-priority tasks.

Extend oil life Condition-based monitoring allows optimized oil usage instead of scheduled replacement.

Reduce maintenance cost Minimize unscheduled downtime and eliminate unnecessary service interventions.

Support compliance and audits Standardized digital logs and alerts help meet class, SIRE and other 3rd party inspection requirements.

Benchmark performance Compare oils, suppliers, and equipment performance over time to inform procurement and operational strategies.

Enable fleet-wide intelligence ASTER’s dashboard centralizes condition data across vessels, empowering shore-based decisions.
