About this course
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.
