Abstract

A maintenance facility includes: a first barge; a first connection portion disposed on the first barge and configured to connect the first barge to a second barge mounted with a device including a maintenance target portion; and a building disposed on the first barge and including a wall portion and a roof portion. On the first barge, a temporary placing space in which the maintenance target portion can be placed is disposed between the first connection portion and the building.

First claim

The invention claimed is:

1. A maintenance facility comprising:
a first barge;
a first connection portion disposed on the first barge and configured to connect the first barge to a second barge mounted with a device including a maintenance target portion;
a building disposed on the first barge and including a wall portion and a roof portion, the building being capable of accommodating the maintenance target portion; and
a crane disposed inside the building, the crane being capable of lifting the maintenance target portion,
wherein, on the first barge, a temporary placing space in which the maintenance target portion can be placed is disposed between the first connection portion and the building.

2. The maintenance facility according to claim 1 , further comprising a utility device for maintenance disposed on the first barge.

3. The maintenance facility according to claim 1 , further comprising a transportation device capable of transporting the maintenance target portion on the first barge.

4. A power generation facility comprising:
a second barge including a second connection portion configured to be connected to a first barge for maintenance;
a power generation device disposed on the second barge; and
a crane disposed, on the second barge, between the second connection portion and a maintenance target portion of the power generation device,
wherein the crane is disposed on a lateral side of a turbine of the power generation facility in an axial direction of the turbine.

5. The power generation facility according to claim 4 ,
wherein the crane is disposed so as to overlap with the power generation device in an axial direction of the turbine.
