HVSim — High Voltage Training Simulator

HVSim is a software-only high-voltage simulation environment designed for training centres delivering HV courses. It allows instructors to demonstrate and assess high-voltage operations, fault conditions, and safety procedures without energised equipment — reducing cost, risk, and maintenance while ensuring compliance with applicable standards.

HVSim complements physical HV equipment by offering safe, realistic simulation with no risk of electric shock or arc faults, lower setup and maintenance costs, flexibility to run on standard PCs, and support for remote or blended learning. It also generates audit-friendly logs to help demonstrate trainee competence to flag-state authorities or classification societies.

HVSim is aligned with the relevant sections of the STCW Code: A-III/1, A-III/2, and A-III/6. It supports both operational-level training for engineers in charge of watch or duty engineers under A-III/1, and management-level or Electro-Technical Officer training under A-III/2 and A-III/6

HVSim is appropriate for STCW HV Operational Level courses, STCW HV Management Level courses, ETO (Electro-Technical Officer) training and assessment, refresher or company-specific HV safety courses, and pre-sea or cadet training for early introduction to HV concepts in a safe environment.

HVSim can be used to teach and assess: safe operation of HV equipment including interlocks, isolation, earthing, and switching procedures; supervision and management of HV operations for management-level trainees; fault diagnosis and safe testing procedures relevant to ETOs; use of protection devices and system design; and compliance with safety and permit-to-work procedures.

HVSim provides verifiable logs and scenario outputs that document student actions, results, and assessment. These can be presented to auditors such as flag-state authorities or classification societies to demonstrate that students have met the Knowledge, Understanding, and Proficiency (KUP) requirements defined in STCW - enabling structured assessment without physical HV hardware.
