Description

Unmanned Submersibles {Underwater Vehicle}

The present application relates to an unmanned submersible, and more particularly, to an unmanned submersible for securing the safety of offshore structures and crew from pirate ships.

In general, offshore structures such as civilian vessels operated at sea cannot be equipped with military weapons to prevent intrusion from the outside. This is because marine structures equipped with military weapons are prohibited from entering the seas or ports of certain countries.

Recently, pirates have appeared on the sea, including in Somalia.

These pirates are small and medium-sized weapons that have abducted the crew of offshore structures and seized the offshore structures and are suffering economic damage.

In order to protect their own ships from these pirates, many countries are engaged in mobilizing navy or international conferences to purge pirates globally and internationally.

In addition, the shipping and shipbuilding industries are preparing measures to ensure the safety of marine structures from pirates.
