The connection of platform pipeline, outlet are connect with the slug catcher suction line；The slug catcher entrance simultaneously with institute
The third port connection for stating threeway before spherical pig receiver entrance, gas phase and the liquid phase difference separated through the slug catcher
Go to downstream installation；The HIPPS system is arranged between the Hai Guandeng platform pipeline and the spherical pig receiver entrance
Pipeline on.
Further, it is provided with and steps on the pipeline between the Hai Guandeng platform pipeline and the spherical pig receiver entrance
The pipe stepped between platform shut-off valve and spherical pig receiver entrance threeway is arranged in platform shut-off valve, the HIPPS system
On line, and platform shut-off valve is stepped on close to described.
Further, the HIPPS system includes HIPPS control panel, two shut-off valves and pressure sensor, two passes
Disconnected valve be arranged in it is described step on the pipeline between platform shut-off valve and the threeway, and by the HIPPS control panel control；It is described
The downstream boundary of two shut-off valves is arranged in pressure sensor.
Further, the pressure rating separation is located at HIPPS system shut-off valve downstream boundary.
Further, the shutdown pressure set-point of the HIPPS system is higher than the shutdown pressure for stepping on platform shut-off valve
Set point.
Further, the two shut-off valve internal diameters that the HIPPS system includes are identical as place pipeline internal diameter.
Because the utility model adopts the above technical scheme, it has the following advantages: the utility model sets HIPPS system
It sets on Hai Guandeng platform pipeline, between the shut-off valve and spherical pig receiver on Hai Guandeng platform pipeline, so that HIPPS
The technique of system downstream receives system, including spherical pig receiver, slug catcher and respective lines valve etc. and can press
It is designed according to low pressure grade, had not only realized the decompression protection for receiving system to integrated artistic, but also mitigate facility weight and reduce throwing
Money, achievees the purpose that cost efficiency.Therefore, the utility model can be widely applied in Offshore Engineering field.
Detailed description of the invention
Fig. 1 is the system schematic of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of offshore platform technique provided by the utility model receives system comprising spherical pig receiver
