What is a ballast water management plan?
Ballast Water Management Plan is the plan for the handling or treating of ballast water onboard a vessel to minimize the transfer of harmful organisms or pathogens in the vessel’s ballast water and sediment.
What are the most important ballast water management techniques?
The main types of ballast water treatment technologies available in the market are:
- Filtration Systems (physical)
- Chemical Disinfection ( oxidizing and non-oxidizing biocides)
- Ultra-violet treatment.
- Deoxygenation treatment.
- Heat (thermal treatment)
- Acoustic (cavitation treatment)
- Electric pulse/pulse plasma systems.
What is ballast water management code?
The Ballast Water Management Convention or BWM Convention (full name International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004) is a treaty adopted by the International Maritime Organization (IMO) in order to help prevent the spread of potentially harmful aquatic organisms and …
What is the first step in an effective ballast management plan?
The first method is to deballast at least 95% of the volume of ballast water from the tank and then re-fill it. This is called the “Sequential method or simply Pump-in, pump-out method)”.
What is d4 in ballast water management?
Prototype technologies. Regulation D-4 covers Prototype Ballast Water Treatment Technologies. It allows for ships participating in a programme approved by the Administration to test and evaluate promising Ballast Water treatment technologies to have a leeway of five years before having to comply with the requirements.
What is D 2 standard in ballast water management Convention?
The D-2 standard specifies the maximum amount of viable organisms allowed to be discharged, including specified indicator microbes harmful to human health. From the date of entry into force of the BWM Convention, all ships must conform to at least the D-1 standard; and all new ships, to the D-2 standard.
What is d2 standard in ballast water management?
What is ballasting and deballasting?
Ballasting or de-ballasting is a process by which sea water is taken in and out of the ship when the ship is at the port or at the sea. Ballast tanks are constructed in ships with piping system and high capacity ballast pumps to carry out the operation.
Who approved the ballast water management plan?
the International Maritime Organization (IMO)
In order to reduce the harmful effects on the marine environment that are spread through aquatic micro organisms transferred from one area to another through ballasting operations of the ship, the International Maritime Organization (IMO) adopted a convention in order to control and manage ships ballast and sediments …
Why ballast water management is important?
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.
