The International Convention for the Control and Management of Ships' Ballast Water and Sediments (Ballast Water Management Convention or BWM Convention) is a 2004 international maritime treaty which requires signatory flag states to ensure that ships flagged by them comply with standards and procedures for the management and control of ships' ballast water and sediments.

The discharge of ballast water and sediments by ships is governed globally under the Ballast Water Management Convention, since its entry into force in September 2017. It is also controlled through national regulations, which may be separate from the Convention, such as in the United States .
Before the final ruling in ballast water standards in 2012, many vessels arriving from outside the EEZ were able to be exempted from safety regulations by exchanging ballast water mid-ocean. Vessels also had to report number of ballast water tanks, each tank's volume, and origin of the ballast water to be discharged.

This water, called ballast water, which contains aquatic organisms typical of the port of arrival, is stored in ballast tanks and is ultimately discharged at the port of departure when the ship is ready to be re-loaded. During this process, aquatic organisms capable of surviving in ballast water are released into new environments and can ...
Organisms targeted by NISA are categorized as aquatic nuisance species, including in particular zebra mussels and Eurasian ruffe.To extend upon NANPCA, NISA authorizes regulation of ballast water, a key factor in the spread of aquatic invasive species; funding for prevention and control research; regional involvement with the Aquatic Nuisance Species Task Force; and education and technical ...
High-pressure jets of hot seawater were used to clean the tanks, and the mixture of seawater and residue called slops was discharged into the sea, as was the oil-contaminated ballast water. The 1954 OILPOL Convention attempted to reduce the harm by prohibiting such discharges within 50 miles (80 km) of most land and 100 miles (160 km) of ...
The IMO has also taken action to mitigate the global effects of ballast water and sediment discharge, through the 2004 Ballast Water Management Convention, which entered into force in September 2017. [55] In December 2023 the IMO adopted a resolution targeting "dark fleet" tankers that form a risk by undertaking illegal and unsafe activities at ...
