A number of different methods exist for disposing of a ship after it has reached the end of its effective or economic service life with an organisation.
[1] Although many options are technically possible, some, such as deep water sinking, are not used for non-military vessels, or have come under increased scrutiny.
Prominent examples of where environmental concerns have complicated the planned disposal of ships have been the Norwegian Cruise Lines vessels SS Norway and SS Oceanic, as well as the French aircraft carrier Clemenceau.
Although in the past there were few effective controls on ship disposal, and the risk of being caught was therefore limited, national authorities as well as environmental organisations are now more vigilant.
[8] Companies caught disposing of ships illegally face hefty fines.
