The Problem

Why Existing Tools Fall Short

Marine engine diagnostics today still rely on spreadsheets, manual ISO corrections, and tribal knowledge — tools that don't scale and can't travel offshore.

Faults Caught Too Late

By the time a cylinder deviation is visible in log sheets, damage is already progressing. Manual checks are periodic — the engine runs continuously.

Hours Spent in Spreadsheets

ISO corrections, shop test comparisons, Pmax and Texh deviations — done manually every performance test, prone to error, consuming time that could go elsewhere.

No Reliable Offline Tool

At sea, internet is limited or expensive. Most web-based tools are useless in the engine control room. Engineers need software that works without a connection.

Reports Take Days to Prepare

Class surveys, management reports, and PSC inspections require structured documentation. Compiling it from raw data manually takes engineers days they don't have.

Capabilities

Built for Marine Engineers

Everything you need to monitor, diagnose, and document engine performance — online or completely offline.

ISO-Corrected Analysis

MAN OEM formulas for Pmax, Pcomp, Texh and SFOC. Compare live data against shop test baselines with full ISO 15550 compliance, automatically.

Per-Cylinder Precision
ML-Powered Diagnostics

Multi-layer diagnostic ensemble: Bayesian frequency scoring, 5 domain discriminators, sensor-sanity + physics-contradiction checks, 123 causal rules. Root causes ranked by probability — with explanations and fix steps.

Explainable AI
Fleet Health Monitoring

Health scores and trend analysis across your entire fleet from a single dashboard. Spot degradation early — before it becomes a port-state issue.

Multi-Vessel
One-Click PDF Reports

Executive summaries, cylinder data tables, deviation charts and diagnostic findings — formatted and ready for class surveys, management, or defect records.

PDF Export
Workflow

From Raw Data to Root Cause in Minutes

Three steps. No spreadsheets, no manual ISO corrections, no cross-referencing shop test tables. Just structured engineering evidence.

1
Enter Performance Data

Input cylinder pressures, temperatures and engine parameters directly from your performance test. Supports all standard MAN two-stroke engines.

2
Automatic Analysis

ISO corrections applied instantly. Deviations calculated against your shop test baseline. The ML engine analyses all parameters simultaneously.

3
Actionable Diagnostics

Ranked root causes with confidence scores, probable cost impact, and step-by-step troubleshooting procedures — ready to act on immediately.

Under the Hood

Multi-Layer Diagnostic Intelligence

PropulsoIQ doesn't just flag anomalies — it reasons through them. The diagnostic engine combines statistical analysis, machine learning and OEM-validated rules to give you ranked root causes, not just alerts.

Every result includes a confidence score and the specific parameters that triggered it, so engineers understand the reasoning — not just the conclusion.
