t. e. 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 ...
Ballast water discharges by ships can have a negative impact on the marine environment. 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 ...
Also established by this ruling was the approval process of Ballast Water Management Systems. Independent laboratories vetted by USCG test the equipment, incorporating EPA Environmental Technology Verification Program land-based protocols. For foreign-type approved systems installed before the compliance dates, a 5-year grandfather period was ...

Regrowth inside ballast tanks. Ballast water discharge from other sides of the world cause a certain type of pollution different from an emission type pollution as it introduces invasive species that can literally cause domestic species to go extinct. After delivering their cargo, empty commercial ships need to take up water from the port of ...
Ship ballast. Ballast is weight placed low in ships to lower their centre of gravity, which increases stability (more technically, to provide a righting moment to resist any heeling moment on the hull). Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel filling with water and/or ...
The ballast water management standards will be phased in over a period of time. As an intermediate solution, ships should exchange ballast water mid-ocean. However, eventually most ships will need to install an on-board ballast water treatment system. [7] A number of guidelines have been developed to help implement the convention. The ...
Ballast water management is subjected to the ballast water exchange standard and the ballast water performance standard. Ships performing ballast water exchange shall do so with an efficiency of 95 per cent volumetric exchange of ballast water and ships using a ballast water management system (BWMS) shall meet a performance standard based on ...
