BOG reliquefaction
Unique value proposition (UVP)
When tankers transport LNG, evaporation of the cargo is inevitable. To maintain a low tank pressure, the BOG needs to be managed. The conventional method is to use BOG as fuel, while excessive gas is burned in a GCU, but this releases harmful gases to the environment, and also waste valuable cargo. A more efficient and environmental-friendly way is to reliquefy BOG and return it to the cargo tanks. This way, pressure is maintained within safe limits and loss of cargo is prevented at same time as harmful emissions is minimized. With Nord Gas Solutions Compact Reliq portfolio, boil-off gas is handled in an efficient, reliable and safe way and the portfolio is developed for easy integration and installation, suitable for all size of LNG Carriers and on both newbuilds and retrofits.
Key Benefits
- The Wartsila Gas Solutions Compact Reliq portfolio reduces harmful emissions by efficiently reliquefying boil-off gas and returning it to cargo tanks, preserving valuable LNG cargo.
- By maintaining tank pressure within safe limits, the solution enhances operational safety and ensures compliance with environmental regulations.
- Designed for seamless integration and installation, the portfolio is suitable for all LNG carrier sizes, supporting both newbuilds and retrofits for maximum scalability and flexibility.
