One of the main concerns for the ship-owners as well as for the ship operators when sailing at the open sea is piracy threat. Those pirates usually choose the important choke points to operate, where all the ships have to pass by at one point or another. Hundreds of ships were hijacked, together with millions of seafarers and civilians were held hostage. Ransom payments for each case reached billion figures, causing incalculable consequence to the shipping industry, military force and international’s wealth.
