The International Maritime Union (I.M.U.) established in 1922 and plays a dymanic role with continuous and significant presence to the shipping Industry of our country for about 80 years.

The establishment of I.M.U. in 1922 was a necessity in order to assist the Authorities for the purpose of creating a modern port which up to now had no any berthing places and port services offered were in a primitive situation.

Piraeus port was a place "to be avoided" by the shipping companies.

At that time joined efforts of I.M.U. Greek Ship Owners Association as well as Chambers of Commerce and with the assistance of Mr Perikles Callimasiotis acting as the "Head of the Port Committee" an autonomous organization was formed to be transformed in 1930 as ther Piraeus Port organization (P.P.O.).

Members of I.M.U. is the majority of the shipping companies representing liner shipping companies as well as tramped ones, and the cruise shipping liner companies, thus contribute to more than 80% to the income of the Piraeus Port budget.

The presense if I.M.U. in Piraeus is strong in cargo and passenger sectors and his elaborating power has played a significant role to the continuous increase of the cargo and passenger traffic, increased the productivity of port services, supported new investments planned by the Authorities.

In our days Piraeus is considered as one of the main Meditteranean Ports and used by almost all mayor shipping liner companies.

International Maritime Union is member of the country's various Chambers as well as to the International Organizations of FONASBA and ECASBA.
