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:
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.

Entries shall be made in the oil record book on each occasion, on a tank to tank basis if appropriate, whenever any of the following machinery space operations take place on any ship to which this section applies— [3] Ballasting or cleaning of fuel oil tanks; Discharge of ballast containing an oily mixture or cleaning water from fuel oil tanks;
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]
The valves that direct the ballast water either over board or to slop tank are controlled by the integrated computer, and a GPS signal further automates the process by including special areas and completes the required input for the Oil Record Book. [2]
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.
It specifies tanker design features that are intended to minimize oil discharge into the ocean during ship operations and in case of accidents. It provides regulations with regard to the treatment of engine room bilge water for all large commercial vessels and ballast and tank cleaning waste . It also introduces the concept of "special sea ...
All ships will have to carry a Ballast Water Record Book and will be required to carry out ballast water management procedures to a given standard.
