INTRODUCTION

The floating power plant can supply electricity to a district or to a specific facility that temporarily uses electricity

It can minimize limitations caused by environmental regulations

It can be used as emergency electric power source

HISTORY In 1940,by the US Army corporation of

engineers, a 30 MW power generation facility put into service in the Philippines is still in operation in Ecuador

In 2000,which is the largest FPP in the world was installed in Mangalore on the west coast of India

DESIGN CONSIDERATION It is designed in such a way that, it operates

only like a ship at ship only requiring fuel for its generating machinery

The FPP is designed to sit in waters and move like a vessel at sea, but rather they are designed for service in protected inland waters such as rivers, lagoons or ports

The completed vessel receives a classification as a “power barrage”

Single barrage designs ranged from 30MW up to 530MW

FUEL The options are often limited in several

countries and one has to use it with available fuels with irrespective of the cost

The fuels used in power station in land or sea is mainly depends on the availability and cost

POWER BARGE DESIGN

BARGE OPERATION The operations are carried out as same as

the land based facilities. The fpp is fitted with on board control room

with data acquisition system with machinery and equipment tools

Step up transformers, motor controllers, switchgear are also installed on barge

TRANSPORTATION One of the more significant differences

of a floating power plant to a land based plant is it’s transportability.

It is being capable of moving the unit from one location to another.

This is achieved with the use of submersible heavy lift ships, designed to move very large structures around the world weighing upwards of 60,000 tons.

A power barge can be moved from one location to another in a matter of weeks and connected to the grid to alleviate local shortages.

WORKING OF FLOATING POWER STATION

The structure of floating power plant can be divided into

1.floating platform 2.rotor with blades-floating turbine

FLOATING PLATFORMThe floating platform gas various functions: It prevents undesirable materials from

entering the rotor of the machine It is equipped with submerged lateral guides

to guide the river water It permits the adjustment of the height of the

equipment above the surface of water

ROTOR WITH BLADES (FLOATING TURBINE)

Floating turbine on the surface of the river with the blades being immersed in the water

The first change is nothing but the displacement of river water proportional to the mass of the floating turbine in its physical space

RECENT DEVELOPMENTS The recent research has come out with FPP

with more sophisticated, light weight, more efficiency and more effective

The latest developments in FPP• Diesel energy• Wind energy• Tidal energy

FPP DIESEL(PHILIPPINES)

SOLAR FPP (JAPAN)

NUCLEAR FPP(RUSSIA)

ADVANTAGES Independent from soil quality Fast supply of electricity to areas with

limited infrastructure Provides addition safety in earth quake and

flooding areas Short delivery time Where land space is limited, large site area

not needed

DISADVANTAGES Infrastructure is costly when working off-

shore The access to installations is critical when

working off-shore

CONCLUSION There are various positive environmental

impacts from the construction of fpp It absorbs and utilizes the energy from

nature there by reducing the use of elements which is harmful to nature
