What Is Ballast Water Management Plan?


A ballast water management plan is a plan for handling or treating the water onboard a vessel to minimize the transfer of harmful organisms or pathogens.

What Is Ballast Water Management Requirements?

The two standards for ballast water management are D-1 and D-2. In order to comply with the D-1 standard, ships must exchange their ballast water in open seas away from coastal areas. The distance between land and water should be at least 200 nautical miles, and the depth should be at least 200 metres.

What Is The Aim Of Ballast Water Management Convention?

In order to prevent the spread of invasive aquatic species through ships’ ballast water, the Convention requires ships to maintain procedures and standards for managing and controlling the water. In the IMO’s view, shipping is a major route for introducing invasive alien species (IAS) to new marine ecosystems.

What Is D1 And D2 In Ballast Water Management?

In the BWM Convention, discharge of ballast water is regulated by two performance standards: D1 and D2. In order to comply with the D1 standard, ballast water must be exchanged within open ocean areas, >200nm from land, and in seas that are 200m deep or more. A ballast water treatment system is covered by the D2 standard.

What Is The Purpose Of Ballast Water?

Fresh or saltwater is stored in the tanks and cargo holds of ships that hold ballast water. In rough seas, it is used to provide stability and maneuverability during a voyage when ships are not carrying cargo, are not carrying enough heavy cargo, or are not able to carry enough cargo.

What Is The Advantage Of Ballast Water Management Plan?

A proper ballast management plan and some additional information can help to avoid operational delays, which will save time and money in the long run. It is easier to report requirements of different post-state authorities.

Why Ballast Water Management Is Required?

By limiting the uptake and subsequent discharge of sediments and organisms from ballast water, the Convention aims to prevent harmful aquatic organisms from spreading from one region to another and to halt damage to the marine environment from the discharge of ballast water.

What Regulation Is Ballast Water Exchange Standard?

A ship performing Ballast Water exchange must have a 95 percent volumetric exchange rate in order to comply with Regulation D-1 Ballast Water Exchange Standard.

What Is Ballasting And Deballasting?

A ship’s ballast or de-ballasting process involves taking in and out of the ship the water that is taken in and out of the ship when it is at sea or at port. Ships with piping systems and high-capacity ballast pumps are used to carry out the operation of ballast tanks.

How Does Ballast Water Work?

In most cases, seawater is pumped into ballast tanks to provide water to the vessel. In addition to adding weight to the ship, crews fill these tanks to improve its stability when it is not carrying cargo. A crew may pump ballast water into dedicated cargo spaces to add extra weight during heavy weather or to pass under low bridges in extreme conditions.

Can I Discharge Ballast Water?

In considering all options above, the ballast water may be discharged in the port or any suitable area, as long as it is acceptable to the port.
