<p>An LNG regasification system and a method thereof are disclosed. According to the present invention, the LNG regasification system includes: a high pressure pump to receive LNG to compress the LNG to a high pressure; a vaporizer to re-gasify the LNG compressed in the high pressure pump; and a turbo fan expander to gain rotational power using energy from the decompression of the LNG by expanding the LNG re-gasified in the vaporizer.</p>
