Abstract

A method for installing an electric power plant comprises preparing a plant yard in the form of a shallow pool connected to a water area. The electric power plant is in a package form comprising a floatable base, and is mounted on a submersible barge and towed. Near the plant yard, the package is unloaded and moved into the plant yard when the water is at a high level. Water is then introduced into a ballast tank of the base of the package to cause the package to sink onto the foundation forming the bottom of the pool.

Claims

1. A method for installing an electric power plant comprising the steps of:

preparing, at a site where the plant is to be installed, a plant yard in the form of a shallow pool having a foundation forming at least part of the bottom of said pool, said plant yard being connected to a water area whose level varies with time due to ebb and flow, the bottom of said pool being at a lower level of said water area at least when said water level is at a high water level,

mounting, in a dockyard, equipment forming the plant on a floatable base to form a floatable package,

submerging a submersible barge having ballast tanks,

moving said package over said submersible barge for support thereon, said barge including ballast tanks,

towing said barge with said package supported thereon to said water area,

unloading said package from said barge by submerging said barge whereby said package floats,

moving said package into said plant yard when the water is at a high level, and

introducing water into said ballast tank of said base of said package to cause said package to sink onto said foundation.

2. A method according to claim 1, further comprising the step of reclaiming said pool with soil or concrete after said package is made to sink onto the foundation.

3. A method according to claim 1, wherein said equipments forming said plant comprise a boiler, a steam turbine, and an electric generator.

4. A method according to claim 1, wherein said equipments forming said plant comprise a circuit breaker, a disconnecting switch, an instrument transformer, and a lightning arrester.

5. A method according to claim 1, wherein said plant yard is connected to said water area by a canal, and said package is moved into said plant yard through said canal.

6. A method according to claim 1, wherein said pool forming said plant yard is sufficiently deep for said package to be moved thereinto only when the water is at the high level.
