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 control

  • Compressor capacity is controlled by means of speed and/or inlet vanes in order to maintain fuel gas control valves within optimum control range.
