Ballast Water Management System Explained | BWMS D1 & D2 Standards | MMD exam and oral This video provides a detailed explanation of the Ballast Water Management System (BWMS) and its critical role in preventing the spread of invasive aquatic species across the world’s oceans. The video begins by explaining how uncontrolled transfer of ballast water has caused serious ecological and economic damage globally. Invasive species such as jellyfish and zebra mussels are transported from one region to another through ballast water, disrupting local ecosystems. Globally, nearly 10 billion gallons of ballast water are discharged every year, carrying more than 7,000 marine species daily. The need for the Ballast Water Management Convention is clearly explained. The convention was introduced to control the spread of invasive species and to overcome the limitations of traditional ballast water exchange methods. The convention entered into force in 2017 and applies to almost all seagoing ships. The video explains the two key compliance standards under the convention: D1 Standard – Ballast Water Exchange D2 Standard – Ballast Water Treatment The D1 standard involves exchanging ballast water at sea using approved methods. The D2 standard requires ships to treat ballast water to meet strict biological discharge limits. The video emphasizes that all ships must comply with the D2 standard by 8 September 2024. Three approved ballast water exchange methods are explained in detail: Sequential method Flow-through method Dilution method Each method is discussed with its advantages, limitations, and operational precautions to ensure ship safety and stability. The video then introduces different ballast water treatment technologies used on modern ships. These include mechanical filtration, chemical treatment systems, and physical treatment methods such as ultraviolet radiation, cavitation, magnetic treatment, and combined filtration–UV systems. Mandatory documentation requirements are clearly explained. Every ship must carry: A Ballast Water Management Plan approved by the flag administration A Ballast Water Record Book to record all ballast operations An International Ballast Water Management Certificate The importance of crew training and familiarization with the BWMS is highlighted, ensuring proper operation, compliance, and safety during ballast operations. This video is especially useful for Merchant Navy cadets, deck officers, marine engineers, Chief Mate and Second Mate MMD orals, and maritime environmental protection studies. 🌐 CONNECT WITH SAILOR RIDER YouTube:    / @sailor_rider   Facebook:   / 19imzynlrp   Instagram: https://instagram.com/sailor_rider?ig...
