when did the ballast water management convention entry into force
Ballast Water Management Convention The International Convention for the Control and Management of Ships' Ballast Water and Sediments (Ballast Water Management Convention) 2004, is an 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 shipsâ€™ ballast water and sediments.[1] The Convention aims to prevent the spread of harmful aquatic organisms from one region to another and halt damage to the marine environment from ballast water discharge, by minimising the uptake and subsequent discharge of sediments and organisms.[1] From 2024 all ships are required to have approved Ballast Water Management Treatment System, according to the D2 standard (see below). Existing ships are required to install an approved system, which may cost up to 5 million USD per ship to install.[2] To assist with implementation the IMO has released 14 Guidance documents in regards to the Convention including the G2 Guidelines for Ballast Water Sampling, G4 Guidelines for Ballast Water management and G6 Guidelines for Ballast Water Exchange.[3]
