ISO-corrected performance analysis, multi-layer diagnostic ensemble, and per-cylinder health scoring, built for Chief Engineers and Technical Superintendents.
Marine engine diagnostics today still rely on spreadsheets, manual ISO corrections, and tribal knowledge, tools that don't scale and can't travel offshore.
By the time a cylinder deviation is visible in log sheets, damage is already progressing. Manual checks are periodic. The engine runs continuously.
ISO corrections, shop test comparisons, Pmax and Texh deviations, done manually every performance test, prone to error, consuming time that could go elsewhere.
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.
Class surveys, management reports, and PSC inspections require structured documentation. Compiling it from raw data manually takes engineers days they don't have.
Everything you need to monitor, diagnose, and document engine performance, online or completely offline.
OEM-referenced formulas for Pmax, Pcomp, Texh and SFOC. Compare live data against shop-test baselines using ISO 15550 correction methods, automatically.
Per-Cylinder PrecisionPhysics-grounded diagnostics with deterministic rules, Bayesian scoring and ML reranking that activates as the confirmed-case corpus grows. Root causes are presented with explanations and recommended checks.
Explainable AIA frontier language model writes up the diagnosis in plain language for the Chief Engineer, superintendent and Class. The finding itself comes from the deterministic engine, not the AI, and your vessel data is never used to train the model.
Frontier LLMPropulsoIQ checks every performance test for physically-impossible values before it ranks anything. Impossible pressure ratios, duplicated records and wrong baselines are caught up front, so the engine never diagnoses on corrupt sensor data.
Bad-data auto-detectionHealth scores and trend analysis across your entire fleet from a single dashboard. Spot degradation early, before it becomes a port-state issue.
Multi-VesselMulti-parameter deviation is tracked over running hours against the shop-test baseline. SFOC, turbocharger efficiency and EGT spread are projected forward to the date they cross a threshold, so maintenance is planned before the alarm.
PredictiveOne report covering engine, history, efficiency and fuel, with every module following the selected vessel. Built for class surveys, management reviews and PSC inspections.
One reportExecutive summaries, cylinder data tables, deviation charts and diagnostic findings, formatted and ready for class surveys, management, or defect records.
PDF ExportTwo modules shipped in 2026 take the same diagnostic engine into fuel economics and IMO compliance, using the data the ship already keeps. No new hardware.
Splits a performance test's excess fuel use into three parts, so maintenance spend goes to the real cause: the engine, the hull or the weather.
Turns compliance into a maintenance signal: your attained vs required CII, graded A-E, straight from the fuel ledger the ship already keeps.
The same evidence chain, now beyond the engine: whether to clean the hull, tune the engine or wait out the weather, and what each does to your CII grade.
Three steps. No spreadsheets, no manual ISO corrections, no cross-referencing shop test tables. Just structured engineering evidence.
Input cylinder pressures, temperatures and engine parameters directly from your performance test. Supports all standard MAN B&W / Everllence B&W two-stroke engines.
ISO corrections applied instantly. Deviations calculated against your shop test baseline. The ML engine analyses all parameters simultaneously.
Ranked root causes with confidence scores, probable cost impact, and step-by-step troubleshooting procedures, ready to act on immediately.
Whether you're reviewing fleet data at the office or running a performance test in the engine control room with no internet, PropulsoIQ runs where you do.
Both versions share the same diagnostic engine, ISO corrections, and PDF export. Pick what fits the vessel. The precision is the same either way.
PropulsoIQ reasons through anomalies instead of just flagging them. Physics-grounded diagnostics with deterministic rules, Bayesian scoring and ML reranking that activates as the confirmed-case corpus grows.
Every result includes a confidence score and the specific parameters that triggered it, so engineers understand the reasoning, not just the conclusion.
A separate AI layer then turns that structured output into plain language. The diagnosis comes from the engine, not the AI, and every statement stays tied to the measured deviation behind it, so the result holds up in Class and PSC review.
PropulsoIQ is actively developed. Here's where we are and where we're headed. No vague promises, just the list.
PropulsoIQ is independent diagnostic software for MAN B&W and Everllence B&W two-stroke engines, with calculation logic based on applicable OEM technical documentation and vessel-specific reference data. We're now opening access to the first engineering teams. No waitlist. Start today, free.
