- the tray 7 is arranged above the hull 2 and below the valve 4.
- the tray 7 is for receiving the hydraulic oil leaking from the valve 4.
- the valve 4 is arranged at a position away from the liquid receiver 5 in the horizontal direction (in the present embodiment, inside the ship width direction from the liquid receiver 5). Further, the tray 7 is arranged at a position higher than the liquid receiver 5, and partially overlaps with the liquid receiver 5 when viewed from above and below.
- the tray 7 has a rectangular shape in a plan view, and is located on the side opposite to the liquid receiver 5 with respect to the bottom plate 71 and the valve 4 (in the present embodiment, inside the ship width direction with respect to the valve 4). It includes a plate 72 and a pair of side plates 73 located on both sides of the valve 4 in the horizontal direction (in this embodiment, the ship length direction) orthogonal to the axial direction of the onboard piping 3.

- the hydraulic oil leaks from the valve 4
- the amount of the hydraulic oil is not so large. Therefore, the leaked hydraulic oil is blocked by the weir 8 and does not flow out into the ocean. In this way, the height of the weir 8 makes it possible to both store the hydraulic oil and allow the liquefied gas to flow into the liquid receiver.
- the tray 7 does not necessarily have to be arranged at a position higher than the liquid receiver 5, and the tray 7 may be arranged side by side with the liquid receiver 5.
- the shape of the tray 7 may be funnel-shaped (circular in plan view).

- a joint for connecting to other equipment piping is provided at the end of the onboard piping
- the above-mentioned ship is the above-mentioned onboard piping arranged above the hull.
- a dump pipe may be further provided. According to this configuration, when the onboard piping is urgently separated from the piping of other equipment, the liquefied gas flowing out from the end of the onboard piping is received by the liquid receiver.
- the liquefied gas which is a low-temperature fluid
