Boil Off Gas Control System
Cargo tank pressure control
- The tank pressure can vary between floating tank pressure setpoints.
- Pressure is reduced by increasing fuel gas firing together with steam dumping or increase of ship speed.
- Pressure is increased by reducing fuel gas firing together with increased fuel oil firing.
- Compressor capacity is controlled by means of speed and/or inlet vanes in order to maintain fuel gas control valves within optimum control range.
