LNG carriers require a thorough preparation process after dry dock to ensure the cargo tanks are safe and ready for loading.
This involves a series of critical steps, including filling the insulation spaces with nitrogen, drying the cargo tanks to remove moisture, inerting them to create a safe atmosphere, gassing up to replace inert gas with LNG vapor, and finally cooling down the tanks to the required temperature.
Each step has specific safety procedures and operational controls designed to prevent hazards such as flammable mixtures, corrosion, and equipment blockage.
Highlights:
The aim of the course is to enable participants to understand the correct procedures and safety precautions for preparing LNG cargo tanks after dry dock.
