Prepare crews for compliant and confident LNG operations using realistic simulation and IGF Code‑aligned training content.

Wärtsilä LNG Bunkering and Fuel Gas Supply System simulator

Set a new benchmark for LNG safety and competence with Wärtsilä’s scalable and customisable LNG Bunkering and Fuel Gas Supply System Simulator. The solution is suitable for both independent learning and instructor‑led IGF Code training, supporting basic and advanced competence development. Designed for both independent learning and instructor‑led training, the simulator prepares crews for safe and compliant LNG operations in line with the IGF Code and STCW requirements.

At a glance

  • What it is: An advanced simulator for LNG bunkering and fuel gas supply system operations, supporting IGF Code training.
  • Why it matters: Builds crew competence and onboard safety for LNG operations, including routine and emergency scenarios.
  • How it works: Replicates real‑world LNG system behaviour using detailed thermodynamic and process modelling, combined with interactive simulation and video‑supported learning.
  • Where it applies: Maritime training centres, shipping companies, simulator facilities, and organisations delivering IGF Code training.

Building competence for safe LNG operations

As LNG adoption increases across the maritime industry, safe handling of fuel gas systems has become a critical competence requirement. LNG bunkering and fuel gas supply operations involve complex processes, strict procedures, and high safety expectations.

The Wärtsilä LNG Bunkering and Fuel Gas Supply System Simulator enables crews to gain practical experience with LNG operations, emergency scenarios, and system behaviour before working with real equipment, reducing operational risk and improving compliance.

Practical LNG bunkering and fuel gas system training

The simulator delivers realistic, hands‑on training for LNG bunkering and fuel gas supply operations, supporting both basic familiarisation and advanced competence development.

Training scenarios include alarms, shutdowns, leakages, hose disconnections, overfilling, and overpressure situations, enabling crews to practise safe responses to LNG‑related emergencies.

It enables organisations to train crews efficiently through a combination of independent learning and instructor‑led sessions, supporting regulatory compliance, consistent assessment, and continuous improvement in LNG safety. Custom models can be developed to reflect specific vessels or terminals, enabling type‑specific training, case studies, and predictive operational analysis.

How LNG bunkering and fuel gas systems are simulated

The simulator replicates LNG bunkering and fuel gas supply system operations using high‑fidelity mathematical models. These models accurately represent LNG thermodynamics, phase transitions, and system behaviour under normal, abnormal, and emergency conditions.

A visual walkthrough demonstrates LNG system components, operational flows, and safety considerations, supporting intuitive understanding of complex LNG processes and enhancing learning outcomes.

The simulator allows trainees to practise:

  • Tank service and bunkering operations
  • Fuel storage and delivery to engines
  • Automation systems, alarms, and safety functions
  • Emergency scenarios such as leakages, hose disconnections, overfilling, and overpressure

The solution scales from laptop‑based setups to full‑mission classroom environments, allowing flexible deployment depending on training needs.
