The WIN GD X-DF Engines course package is currently in the active phase of processing and structuring the recorded technical material. The AtSea project team is opening a pre-sale for the full course package, granting lifetime access to all already published modules and all future updates.
This pre-sale offer is limited.

2-Stroke Dual Fuel WIN GD X-DF ENGINES is a professional engineering course on modern low-pressure, two-stroke, dual-fuel WinGD X-DF series engines. The course is designed to provide a deep understanding of the construction, control, operation, and gas safety of engines used on LNG and Dual Fuel vessels.

Key X-DF Concept

At the core of X-DF lies the Lean-Burn Otto process with low-pressure gas admission, which ensures:

✓ Operation on gas with pilot diesel ignition
✓ Compliance with IMO Tier III without SCR and EGR
✓ High reliability of mechanical components
✓ Fuel flexibility without compromising engine lifespan

What the Package Includes

Main course topics:

→ Philosophy and construction of X-DF engines
→ The UNIC-DF control system and its architecture
→ Injection control, gas admission, and pressure management
→ Combustion process and Dynamic Combustion Control (DCC)
→ Environmental modes and IMO Tier III compliance
→ Engine operation and Diesel ↔️ Gas transitions
→ Gas safety systems: Gas Protections, Gas Trip, and Gas Interlock
→ Operation of GVU (Gas Valve Unit), ventilation, degassing, and inerting

Who This Course Is For

✓ Marine engineers on LNG and Dual Fuel vessels
✓ Chief and Second Engineers
✓ Technical Superintendents
✓ Marine Engineers planning to work with X-DF engines

The course focuses on a practical understanding of the engine’s operational logic, not just a formal study of manuals.

Format and Access

✓ Online access via the AtSea platform
✓ Lifetime access to all modules
✓ Automatic receipt of all future updates

The 2-Stroke Dual Fuel WIN GD X-DF ENGINES package is a systematic engineering foundation for confident and safe work with modern two-stroke gas engines.
