PYTHIA is based on processing of measured data. It delivers cylinder pressure monitoring, engine diagnosis, and fleet performance analytics for marine diesel engines — from a single portable device to a full ship-to-shore monitoring suite. An embedded simulator is also used to support the analysis.
Choose between portable periodic diagnosis systems or fully automated online monitoring suites — both built on the same proven PYTHIA Analysis Tool.
For ME engines with installed pressure sensors. Exports and converts engine data to PYTHIA format for diagnosis with zero hardware installation.
Portable solution for periodic M/E and D/G measurement and diagnosis. Measurement from indicator valve. Complete analysis in less than 10 minutes.
Combined portable system and USB utility. Cylinder pressure can be either measured manually or exported from installed sensors.
Installed server capturing cylinder pressure automatically from M/E installed sensors. Three measurements per day, transferred to office automatically.
Continuous, automated cylinder pressure monitoring using installed sensors with 5-minute acquisition cycles. Engine performance on-board and at office updated automatically. Manual D/G option included.
Complete engine and vessel monitoring. Provides navigational data, torque-meter, flowmeter data, fuel tank levels, D/G power and propulsion efficiency analytics.
All PYTHIA solutions share the same Pythia diagnostic tool — what differs is the cylinder pressure data acquisition methodology and the data transfer method to your office. Choose the workflow that fits your needs.
For ME (electronic) engines already equipped with cylinder pressure sensors by the engine maker. No hardware installation at all — just a USB stick and software.

PYTHIA replaces conventional performance analysis with quantified, actionable engine intelligence — reducing cost, effort, and unplanned downtime.
Maintain based on actual component condition, not only operating hours. Avoid unnecessary replacements, detect real faults early, and evaluate repair work.
DNV-GL type approved power and fuel consumption methodology. Cross-validate flowmeter and torque-meter readings automatically. New software generates results for SFOC reduction potential (total and per system).
Data required for EEXI, CII calculations and EPL studies provided automatically. Support for Tier-II, Tier-III, DF and engines equipped with SCR (LP & HP) and EGR.
Optimise VIT, SOI, EVO settings to minimize SFOC. Proposed adjustments per cylinder and subsystem — no major spares required.
Auto-generated PDF reports, automated office data import, and measurement server eliminate repetitive manual work for superintendents. New performance summary report created for submission to vessel.
PYTHIA derives maximum insight from the minimum number of sensors — keeping long-term maintenance low and reliability high in the marine environment. Diagnosis is based mainly on cylinder pressure measurement (entire cycle), not noon report data.
Developed by Prof. D.T. Hountalas and his team, refined through decades of practical application across the world's leading shipping companies.
Power and FOC estimation methodology validated and type approved by Germanischer Lloyd in collaboration with TESTO AG for on-board NOx verification.
Field testing at Hyundai, Mitsui, Namura, CMD China, SWS China. Trusted third-party evaluator at major shop tests and sea trials worldwide.
Software components provided to AVL, Caterpillar USA, Daimler-Benz (Mercedes-Benz), and Robert Bosch SA. Sensor technology partnership with Kistler AG.
Continuous development for Tier-III, Dual Fuel, EGR, and SCR engines. Software updates twice yearly, included in support contract at no charge.
Full technical support, software updates, and expert performance analysis — available from day one.
Ticketing system with response under 12 hours. Remote access for commissioning, updates, and troubleshooting without travel. Raw measured data can be submitted to PYTHIA for analysis.
Monthly engine performance analysis by the PYTHIA expert team. On-board attendance available worldwide through local specialists.
Additional services available for Pythia and non-Pythia users. Shop test attendance, sea trial evaluation, alternative fuel testing, and more.
