Ship Energy Audit Course
This course gives you the tools and knowledge to improve the energy performance of vessels of every type. You will learn to identify where energy is lost, take accurate measurements on board and propose efficient solutions that reduce fuel consumption and emissions, gaining the skills to assess and improve the energy efficiency of ships in a field driven by sustainability goals and environmental regulation.

What is the Ship Energy Audit Course?
This short course prepares you to carry out a complete energy diagnosis of a ship. You will study the concepts of energy performance applied to vessels, the ship's energy architecture, mission profiles and the variables that drive consumption, together with efficiency indicators such as consumption per mile or per tonne carried; the measurement systems, instrumentation and onboard data sources used to characterize energy use, including AMS, PMS, SCADA and noon reports, and how to design a measurement campaign with reliable data; the diagnosis of propulsion, main machinery, generators and auxiliary systems, with the identification of losses such as hull fouling, propeller degradation and operation away from the optimum point; and the analysis of data and modeling of consumption to identify operational and technical savings.
What sets this course apart: a structured diagnostic method that goes from the energy balance to a costed improvement proposal; hands-on use of measurement instruments, data loggers and onboard monitoring data; coverage of the whole vessel, from engines and propulsion to HVAC, refrigeration, pumps and hotel services; a clear link between energy savings, emission reductions and the applicable national and international efficiency rules; and an integrative project in which you carry out and defend the energy diagnosis of a real or realistic ship.
Program highlights
- Energy foundations: onboard energy balance, mission profiles and efficiency indicators per mile and tonne.
- Measurement: flow meters, power analysers, data loggers, AMS, PMS, SCADA and noon reports.
- Propulsion diagnosis: main engine, shaft line, propeller and the power-speed relationship.
- Auxiliaries: generator sets, load sharing, pumps, ventilation, HVAC, compressors and refrigeration.
- Savings: slow steaming, trim optimization, weather routing, variable speed drives and heat recovery.
- Integrative project: a full energy diagnosis of a ship with a costed improvement plan.

Questions about the Ship Energy Audit Course
To find out where and how energy is used on board, quantify the losses and identify practical opportunities to reduce fuel consumption and emissions.
The whole vessel: main propulsion, shaft line and propeller, generator sets and electrical distribution, and auxiliary systems such as pumps, ventilation, HVAC, compressors, refrigeration and hotel services.
No. The course uses real operating data, case studies and measurement exercises that you can follow online. If you work on board, you can apply the methods directly to your own vessel.
Yes. The diagnosis module explains how fouling, propeller degradation, misalignment and operation away from the optimum point increase consumption and how to detect them in the data.
Operational measures such as slow steaming, trim optimization, weather routing and better use of auxiliaries, and technical measures such as engine improvements, variable frequency drives, heat recovery and automation.
You plan and carry out the energy diagnosis of a ship, build its consumption baseline, propose improvement measures and assess their savings, emission reductions and feasibility.
Fully online, through a virtual campus available 24/7, with practical exercises and case studies, live sessions that are recorded and tutorials with the teaching staff.
The course comprises 300 hours of study across 5 modules of about 60 hours each and ends with an integrative project. You can progress at your own pace within the schedule set when you enroll.
