The "Grand Port Maritime" (GPM) is a public administrative institution.
There are 7 Grands Ports Maritimes in France : Rouen, Dunkirk, Le Havre, Nantes/St Nazaire, La Rochelle, Bordeaux, Marseilles/Fos.
The Port Authority is governed by 3 boards :
- The executive board, whose president is designated by the State, is responsible for strategic planning and the management of the Port.
- The supervisory board, with 17 members (State appointees, local authority representatives, "qualified persons" - for example Chamber of Commerce - and employees of the GPM), meets four times a year to review the executive's policy and budget proposals.
- The development board will include 40 members (port professionals, local authorities, port based companies and associations). It has a consultative role on strategy and tariffs. It will meet at least twice a year.
