1000 Mega Watt Power Plant
OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a
platform and can be located about 30 Kilometers
off the coast.
This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)

The New DSI-OTEC
CONCLUSION:
Clean energy and clean water are the
fundamental needs. These are in
short supply in Developing Nations.
A technically Feasible New OTEC System
is presented as a good source for
a cost-effective, clean, renewable energy.

The New DSI-OTEC

CONCLUSION:
It is a Game Changer that will meet the
Long-term Energy demands of the World.
The New OTEC is definitely to be considered
by the industry seriously as a source of
Pollution free, Alternate source of energy.

OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a

This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)

1000 Mega Watt Power Plant
OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a
platform and can be located about 30 Kilometers
off the coast.
This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)

1000 Mega Watt Power Plant
OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a
platform and can be located about 30 Kilometers
off the coast.
This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)

1000 Mega Watt Power Plant
OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a
platform and can be located about 30 Kilometers
off the coast.
This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)

1000 Mega Watt Power Plant
OTEC Support Semi-Submersible Platform

DSI is offering a proposal for a One Thousand
Megawatts power plant that can be built in the
deep waters off the East coast of Tamil Nadu or
other tropical countries and islands. The power
plant will be designed to produce 1000 MW on a
platform and can be located about 30 Kilometers
off the coast.
This will be on a Floating semi-submersible
Offshore Platform type in class ABS/DnV that
resists 1000 years return storm, quite stable for
the harsh environment of the Bay of Bengal and
of the Tropical oceans. (Experimentally Verified)
