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. [2]
Other examples of regulations include regulations regarding ballast water dumping, fire safety, small vessel regulations, vessel registration fees and Arctic shipping. [13] Other regulations have been repealed, such as regulations regarding anchorage, hull inspection, or navigation of minor waterways such as the St. Clair River or Burlington ...
The Coast Guard issued ballast water regulations in 2012. [14] Under the authority of the Clean Water Act, the Environmental Protection Agency (EPA) published its latest Vessel General Permit in 2013. The permit sets numeric ballast water discharge limits for commercial vessels 79 feet (24 m) in length or greater.
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 ...
The Code sets out regulations for shipping in the polar regions, principally relating to ice navigation and ship design. The international framework aims to protect the two polar regions — the Arctic (north pole region) and Antarctic (south pole region), from maritime risks. [2] The Code entered into force on 1 January 2017. [2] [3] [4]
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 ...
The fresh water load line is an amount equal to Δ / 4T millimetres above the summer load line where Δ is the displacement in tonnes at the summer load draft and T is the tonnes per centimetre immersion at that draft. In any case where Δ cannot be ascertained, the freshwater load line is at the same level as the tropical load line.
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 ...
