Curriculum
Programme Structure
The programme is structured in 5 modules, listed below in order of study.
01
Fundamentals of Naval Energy Diagnosis, Consumption Structure and Functional Architecture of On-Board Energy Systems
- Concepts of energy performance applied to boats: specific consumption, energy balance, global performance and operational losses
- Vessel energy architecture: main propulsion, auxiliary generation, electrical distribution, hotel services and consumption of Deck
- Typologies of mission profiles and their impact on energy demand: ocean navigation, cabotage, manoeuvreing, waiting, anchoring and port operation
- Critical variables that condition consumption: speed, draught, sea state, meteorology, transported cargo and operating regime
- Key indicators of energy efficiency: consumption per mile, consumption per ton transported, energy per hour and associated carbon footprint
02
Measurement, instrumentation and data capture systems for the integral energy characterisation of the ship
- Variables to be measured in an energy diagnosis: fuel, power, flow rate, temperatures, pressures, vibration and electrical parametres
- Field and Engine Room Instrumentation: Flowmetres, Electric Analysers, Thermal Sensors, Monitoring Systems and Data Loggers
- Integration of embarked data sources: AMS, PMS, SCADA, NOON Reports, historians and manual operation records
- Data quality and metrological traceability: calibration, uncertainty, time synchronisation and reading validation
- Design of on-board measurement campaigns: scope, duration, monitoring points, operating windows and interference control
03
Power diagnosis of propulsion, main machinery and auxiliary systems with identification of losses and deviations
- Energy evaluation of the propulsive system: main engine, axle line, propeller, load regime and power-speed ratio
- Diagnosis of auxiliary motors and electricity generation: efficiency of generator sets, load sharing, demand peaks and partial loads
- Energy analysis of auxiliary systems: pumps, ventilation, HVAC, compressors, refrigeration and hotel services
- Identification of mechanical and operational losses: hull fouling, propeller degradation, misalignment, overloading and operation out of optimum point
- Evaluation of non-productive consumption: excessive idle, unproductive times, inefficient starts/stops and inadequate use of auxiliaries
04
Data analysis, consumption modelling and determination of opportunities for improvement in the energy efficiency of the ship
- Methods of energy analysis: balances, benchmarking, trends, correlations and comparisons by operating condition
- Consumption modelling based on mission profile: speed, load, climate, routes and behaviour of the propulsive plant
- Identification of Savings Operational Opportunities: Slow Steaming, Trim Optimisation, Meteorological Routing and Auxiliary Management
- Identification of technical savings opportunities: improvements in motors, frequency drives, heat recovery and consumption automation
- Estimation of energy saving potential and emission reduction: scenarios, sensitivity and effects on CAPEX/OPEX
05
CapStone Project Energy Diagnostic of a Boat: Technical Assessment, Optimisation Proposal and Defence of the Case
- Selection and characterisation of the case study: type of ship, operating profile, energy systems and exploitation context
- Diagnostic plan definition: variables, instrumentation, data sources, schedule and evaluation criteria
- Baseline elabouration and consumption analysis: segmentation by operating modes, loss detection and performance evaluation
- Formulation of energy improvement measures: operational, technical, maintenance and digital control of consumption actions
- Technical-economic evaluation of the proposal: Expected savings, emission reduction, implementation risks and operational viability
