- FIG. 1 is a schematic diagram of a bilge discharge promoting pipe.
- Drawing 2 is a mimetic diagram which looked at the part where a bilge discharge promotion pipe is attached from the upper surface.
- FIG. 3 is a schematic view of the bilge discharge promoting pipe, particularly the second portion.
- a cargo ship has a bilge well near the bottom of the cargo hold. Water (bilge) contained in the cargo (cargo) is sent to the bilge well through a drain outlet provided on the bottom surface of the hold. The bilge sent to the bilge well is discharged out of the ship as needed depending on the situation.
- Water (bilge) contained in the cargo (cargo) is sent to the bilge well through a drain outlet provided on the bottom surface of the hold.
- the bilge sent to the bilge well is discharged out of the ship as needed depending on the situation.
- the ship In the ore dedicated ship, the ship is divided into a plurality of holds 100 by bulkheads 130. Further, a bilge well 110 is provided near the bottom of the boat below the hold 100.
- the partition wall 130 is supported by a lower stool (Lower Tool) 120 on the bottom surface (also referred to as Tanktop) 110a side of the hold 100.
- the partition wall 130 is supported by an upper stool 140 on the deck (also referred to as an upper deck) 100b side.
- the partition wall 130 is formed of a corrugated plate, for example.
- the partition formed by the corrugated plate is also referred to as “corrugated bulkhead”.
- the water (bilge) contained in the cargo (cargo) 200 is sent to the bilge well 110 through a drain port (not shown) provided on the bottom surface 110 a of the hold 100.
- the bilge sent to the bilge well 110 is discharged out of the ship as needed depending on the situation.
- a wire mesh-like strainer (filter) provided at the discharge port to the bilge well 110 is clogged, so that the bilge is not discharged to the bilge well 110 and the periphery of the cargo 200 is May remain.
- the upper surface 200a of the cargo 200 reaches a high position from the bottom surface 110a of the hold 100. For this reason, it is assumed that it is difficult to discharge the bilge from the drain outlet to the bilge well 110 as compared to the bulk carrier.
- the bilge discharge promoting pipe 10 of this embodiment is configured by connecting the first portion 20, the second portion 30, and the third portion 40 in this order.
- the bilge discharge promoting pipe 10 is configured using a tubular member (pipe) made of any suitable material. A plurality of pipes are connected and processed as necessary to form a bilge discharge promoting pipe 10 having a predetermined shape.
- the bilge discharge promoting pipe 10 will be described as a structure in which the first portion 20, the second portion 30, and the third portion 40 are connected, but is not limited thereto.

- the pipe may be integrally formed.
- the first portion 20 is mainly provided in the lower stool 120.
- One end (first end) 22 of the first portion 20 is provided so as to be located in the bilge well 110.
- the other end portion (second end portion) 24 of the first portion 20 is provided so as to be positioned near the upper surface 120 a of the lower stool 120.
- the second portion 30 is provided vertically along the partition wall 130 from the upper surface 120a of the lower stool 120 to the vicinity of the lower surface 140a of the upper stool 140.
- One end portion (first end portion) 32 of the second portion 30 is connected to the second end portion 24 of the first portion 20.
- the other end portion (second end portion) 34 of the second portion 30 is provided so as to be positioned near the lower surface 140 a of the upper stool 140.
