Emergency Shutdown System or “ESD” system) shall be capable of initiating a shut down of the vaporizers. The detection of low temperatures downstream of each vaporizer will shut down the individual SCV to protect downstream piping and Equipment from being subjected to lower than design temperatures. Other shutdowns of individual vaporizer trains or groups of vaporizer trains will be determined during detailed design. Pipeline gas Btu control is not included in the Scope of Work. Two vent stacks, one high pressure and the other low pressure, shall be provided to vent process plant vapor releases to a safe location. Two (2) 36-inch sendout lines (“Sendout Pipelines”) shall be provided. The sendout piping will be stainless steel for approximately 300 ft and will run above ground, and thereafter, the lines will be carbon steel (coated and wrapped underground). Takeoffs on the above ground lines shall be included to provide fuel gas for onsite users (SCVs and power generation facility). A metering station shall be provided (“Master Sendout Meter Station”) and will be fed from the two Sendout Pipelines, and will meter and record the Natural Gas exports from the Facility. The outlet from the Master Sendout Meter Station will terminate at a flange, which will be connected by Owner’s other contractor(s) to the Natural Gas pipelines leaving the Facility (the “Export Pipelines”). Ultrasonic type flowmeters (“Master Meter”) shall be provided at the Master Sendout Meter Station to measure and totalize the flow. In addition to the export to the Export Pipeline, fuel gas shall be consumed in the Facility for vaporization of the LNG in the SCVs and for power generation. The normal source of fuel gas for vaporizers will be from the discharge of the BOG Compressors. Alternate supplies of fuel will be from downstream of the vaporizers. The fuel is heated in separate coils in the water bath of the SCVs. Each vaporizer shall have a coil designed to heat the amount of fuel required for that vaporizer. For power generation, fuel gas from the Sendout Pipelines shall be heated and reduced in pressure from the Sendout Pipeline pressure to meet power generating equipment requirements. A knockout drum shall be provided downstream of the pressure reducing valves.
