All international sea going ships under the Convention must implement a ‘Ballast water management plan’ that enables the ship to manage their ballast water and sediment discharge to a certain standard. [7] The plan is designed to meet the requirements for compliance with the Convention and the G4 Guidelines produced by the IMO.
The Convention will require all ships to implement a "Ballast water management plan" including a ballast water record book and carrying out ballast water management procedures to a given standard. Guidelines are given for additional measures then the guidelines. The goals of the convention are to minimise damage to the environment by:
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.
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 ...
The Polar Code applies to ships operating in Polar Waters. The Polar Code stems from previous IMO documents, including voluntary guidelines in both 2002 [5] and 2010. [6] As part of ongoing international work on the Polar Code, an IMO Workshop on the code's Environmental Aspects was held in Cambridge, United Kingdom, in September 2011.
The VGP sets numeric ballast water discharge limits for large commercial vessels. The limits are expressed as the maximum acceptable concentration of living organisms per cubic meter of ballast water. [11] The Coast Guard worked with EPA in developing the scientific basis and the regulatory requirements in the VGP. [5]
As of 1 January 2020, new emission standards are enforced for fuel oil used by ships, in a regulation known as IMO 2020. The global sulphur limit (outside SECA's) dropped from an allowed 3.5% sulphur in marine fuels to 0.5%. [ 11 ]
The port state control (PSC) makes inspection of ships in port, taken by a port state control officer (PSCO). Annual report of Paris MoU reported that a total of 74,713 deficiencies were recorded during port state control inspections in 2007, which deficiencies resulted in 1,250 detentions that year. [13]
