[MUSIC PLAYING] For most ships, ballast water is essential for ship stability and proper weight distribution. But when ships take on ballast water from natural water sources, they also take on the organisms living in that water. These stowaways can include marine plants, animals, eggs, and other microorganisms invisible to the naked eye. When let loose in a foreign habitat, these tiny stowaways can disrupt the ecosystem, devastate the natural habitat, and cause long term economic damage to local communities, not to mention the costly effect on your ship and its crew. Failure to comply with proper ballast water management regulations can lead to flag state deficiencies, invalidation of certificates, detainment and restricted entry by Port State Control, and even civil and criminal liability for damages, which can be applied to both ship owners and crew members. That's why it's essential for seafarers to be trained in proper ballast water management procedures. In this program, we'll go over the rules and requirements for proper ballast water exchange and tell you how to complete your Ballast Water Management Plan and ballast water record book. We'll give you 10 important precautions to follow when managing your ballast and we'll walk you through how to respond should your ship be subject to a ballast water inspection. Finally, we'll give you a short look at what's to come and finish with a recap of everything we've learned. The first step in effective ballast water management is properly completing a ballast water exchange. Ballast water exchange is a management practice that's really intended to remove high risk water from ballast tanks that is uptaken in a coastal or port environment and replace that water with water from the mid-ocean environment. Once a ballast water exchange is conducted, it's much tougher for tiny stowaways picked up in coastal environments to survive in deep sea salt water. Any stowaways remaining in the ballast tanks will be adversely affected by the higher salinity content of deep sea salt water. Just the same, any deep sea stowaways will have a much more difficult time surviving when introduced to waters close to the shore. According to the latest IMO guidelines, these exchanges should be completed at least 200 nautical miles from shore and in waters no less than 2,000 meters deep whenever possible. And the US EPA's Vessel General Permit requires ships engaged in Pacific near shore voyages to conduct a ballast water exchange when sailing beyond 50 nautical miles from shore. However, if the ship travels beyond 200 nautical miles, then the exchange must occur beyond 200 nautical miles. In US waters, Coast Guard requirements state that any ships that have operated in international waters must either complete a mid-ocean exchange beforehand or retain their ballast when in port. There are two Coast Guard-approved exchange methods, depending on a ship's particular ballast structure. In the empty-refill exchange method, 100% of the ballast tank is emptied before refilling. In the flow through method, mid-ocean water is pumped in as existing ballast water is forced out an opening in the top. An amount of water three times the volume of the ballast tank must be pumped through. For every vessel measuring 300 gross tons and above, or that can hold more than 8 cubic meters of ballast water, a one time Notice of Intent, or NOI, shall be submitted through the EPA website. [MUSIC PLAYING] No matter which rules apply to you, your ship's ballast management procedures must be outlined in a Ballast Water Management Plan, or BWMP, to be kept on board and ready for inspection at all times. A Ballast Water Management Plan is important for the vessel officers and crew to make sure that there's a clear understanding of the operational needs for the ballast water, in terms of sequencing of tanks, when not to discharge certain tanks while other ones are ballasted or not ballasted. So it's got safety implications for the vessel and making sure that the entire crew and officers understand the importance of why ballast water management needs to be done. The contents of a BWMP may vary according to flag state, international, and local standards. But they should always identify the ship's Ballast Water Management Officer, spell out clearly all of the ship's specific on board training and ballast water handling practices, and be written in the company's designated working language. The US Coast Guard requires a translation into English, French, or Spanish to be kept on hand if the ship's working language is different. [MUSIC PLAYING] The third and final procedure required by the latest IMO standards is an on board ballast water record book. This is not the same as a Ballast Water Management Plan. Record books shall log any and all ballast operations, including taking ballast, deballasting, and exchanges of ballast water, including the time it took place, the date it happened, which tanks were involved, how much water was exchanged, and the coordinates where it took place. Some record books contain additional information, like water temperatures and salinity. How much information you keep may depend both on your ship and the regulations in the ports you may enter. Keeping track of this information for each ballast tank during operations is essential. Otherwise, when time comes to deballast and submit the required reports, you may not know the source of the water or when it was ballasted. How far back shall these ballast records go? A shipboard records of ballast operations should be kept for a minimum of two years from the last point at which an entry was made into that log. We need to be able to see the history of where ballast water had been sourced and how it been managed in order to assess the risk and also to make sure that things have been managed properly. [MUSIC PLAYING] Before you're ready to set out, you and the rest of your crew need to be aware of 10 necessary precautions. First, keep in mind, a water exchange cannot be performed while a ship is at full steam. And the entire process may take between half a day to two days. You need to factor this into your plan. It is required to do water exchanges during the day, when bottom-dwelling creatures are less likely to come to the water's surface. And keep away from any marine sanctuaries, preserves, coral reefs, and sewage outfalls. In the event of high waves or turbulent waters, it is not recommended to conduct a water exchange, due to concerns for safety of both crew and vessel. Remember that not all ships are alike. If you're conducting an empty-refill exchange, empty tanks one by one or in balanced pairs to maintain the ship's weight distribution. If you're using the flow through method, you should remove manhole covers and Butterworth openings for proper venting. Whatever your method, clean tanks thoroughly and on a regular basis. Sediment in tanks builds up over time and must be cleaned either mid-sea or disposed of in a proper shore side facility and not in coastal waters. Run frequent assessments of ballast equipment to make sure everything's in proper order. Know that elements like weather conditions, including icing on deck and low visibility, can also be a factor. Even the ship's own sailing conditions can be affected. In the event of too much trim, bridge visibility during water exchanges may not be sufficient. [MUSIC PLAYING] Finally, make sure you know everything that's required of you from port states. This means filling out a Ballast Water Report, which looks something like this. Many port states require this form to be submitted at least 24 hours before entering. An accurate report and well maintained handling log is often the difference between staying on schedule and a thorough inspection. Remember, some standards are stricter than others. Failing to meet specific port requirements is the most common mistake in ballast water management. [MUSIC PLAYING] Even with proper procedures in place, a ship and it's crew should still be prepared for an inspector to board. Herein lies the importance of knowing the rules and keeping thorough records. As long as you keep all the necessary paperwork on hand, the inspection will go smoothly. An inspector will ask for these three things-- the ballast record book, the Ballast Water Management Plan, and the ballast water sample. The ship's Ballast Water Management Officer will then meet with the inspector and provide all the necessary paperwork. Yes, sir. This is empty? Yes, sir. This is start to fill? Mm-hmm, yes. And this is full? Full. Very good record, Nate. Very good record. This is what we like to see. A concise record will always expedite the ballast inspection. Yes, sir. yeah. The inspector will then take a ballast water sample to ensure the ballast water meets approval. Sample collections usually are for, just for salinity readings, to make sure that the salinity level is as high as it should be, given that the water should be from an open ocean, mid-ocean source. But we also may do some additional biological sampling, as well. If your ship passes all the tests, you're free to go. If not. Red flags when we were to come aboard a vessel would be a vessel that was unaware of the rules for the port state, a vessel that failed to file the Ballast Water Reporting Form prior to arrival, a vessel which did not conduct exchange, a vessel that completes the Ballast Water Reporting Form less than thoroughly. Don't get held up with lengthy inspections and costly fines. Make sure all of your documents are clear, concise, and in compliance with all ballast water management regulations. Most nations are continuing to move towards the stricter guidelines outlined in the IMO's Ballast Water Management Convention by adopting stricter standards of their own. For instance, the latest version of EPA's Vessel General Permit adds specific ballast water discharge limits. If tests show the quantity of living organisms in the ship's ballast water to be greater than 10 per cubic meter, even after completing a ballast water exchange, the ship shall not discharge its ballast in US waters. Tests and limits for strains of cholera and E. coli have also been introduced. And ships are being outfitted with a variety of IMO-approved ballast water treatment systems that kill or remove living organisms in ballast water to help meet these new standards. The US Coast Guard has adopted a time frame for implementation for ships to install ballast water treatment. You should refer to your vessel's or your company's standard operating procedure to determine the water treatment system aboard your ship, or the plans for its implementation. [MUSIC PLAYING] Now let's recap what we've learned, so that you can make sure to meet all the latest requirements in ballast water management. We learned about the three necessary procedures in ballast water management as well as where, when, and how to properly implement them, a ballast water exchange, a Ballast Water Management Plan, and a ballast water record book. We also went over 10 important precautions you and your crew should take in proper ballast water management. Don't run on full steam. Plan for between half a day and two days. Do it during the day and away from any areas where you're likely to pick up invasive species. Don't conduct an exchange in rough waters. If you're using the empty-refill method, make sure to stay balanced. And if you're using flow through method, ensure proper venting. Make sure to clean and check ballast and all related equipment. Be aware of the elements you may encounter. And know what's required of you by various port state authorities. In the event of an inspection, an inspector will ask to see your Ballast Water Management Plan and your ballast water record book and will take a sample of the water in your ballast tanks. In closing, remember, knowing the requirements and keeping clear, thorough documentation are the two most important steps to protecting the marine environment and your ship. [MUSIC PLAYING]
