The air mast 18 is mounted on a sinking deck 19 of the vessel, which sinking deck 19 may also be referred to as a sinking deck, which is an open deck having a vertical height below the height of the open deck 15 of the liquid cargo area. The settlement deck 19 may be arranged at the bow or stern of the liquid cargo area depending on the characteristics of the vessel design.
The height of the air mast 18, together with the height of the hull structure at the location where it is mounted, should be less than the design height of the bridge, so that the clearance height of the vessel is less than the design height of the vessel, and the vessel can pass all bridges along the river or along the river.
Specifically, the ventilation pipeline comprises a plurality of inlet pipelines 20 and outlet pipelines 21 respectively connected with the plurality of inlet pipelines 20. The inlet pipelines 20 are respectively connected to different vent ports of the cargo tank dome 16, and each inlet pipeline 20 is provided with a safety valve 22 and a ball valve 23. By connecting a plurality of inlet lines 20 to one outlet line 21 and laying the outlet line 21 horizontally along the weather deck 15 of the cargo area, multiple paths of boil-off gas flowing out of the cargo tank 17 can be combined into one path for output, so that cavitation can be prevented from occurring in the outlet line 21 and inerting and purging of the line can be facilitated.
The inlet pipeline 20 and the outlet pipeline 21 are both made of low-temperature stainless steel or low-temperature resistant materials which are adaptive to the temperature of the transported goods.
When an outlet pipeline 21 in the ventilation pipeline is arranged, the shortest path between the safety valve 22 and the ventilation mast 18 is selected for laying, and when the shortest path is laid, the pipe diameter change is avoided and the elbow is avoided as much as possible, so that the pressure loss caused to the outlet pipeline 21 when the safety valve 22 acts can be reduced.
