SCHIFFSTECHNIK | SHIP TECHNOLOGY Detailed lab testing can take up to a few weeks »Wouldn’t it be nice to know?« According to the ballast water expert, a lot of people do not understand how strict the regulations are, but proper testing would also make sense from the economical perspective, he thinks: »If you don’t sail under the flag of one of the above mentioned flag states, you don’t have to test your ballast water. But wouldn’t it be nice to know it that works properly after you invested up to 1 mill. $ for equipment and installation?« Haraldsson asks. In his view, owners should spend a couple of thousands of dollars, »because if you leave the drydock and come to the first port and the PSC wants to test your newly installed system and it fails, you have a problem. Even if it has just been installed: if it has to many living organisms, you are not allowed to leave port. The charterer won’t be happy, the owner won’t be happy © CTI Maritec while for just a relatively small amount of money you could be sure.« There are also questions of liability arising: If a system is tested right after installation at the yard and it fails, the yard or the manufacturer has to fix it. If the owner does not test it and sails for one week and it fails »you have a legal case.« »The ballast water regulation is already in force. You don’t have to test your system, but you have to use it. As soon as you have installed a ballast water system, you are not allowed to exchange untreated water«, he says. CTI Maritec has looked into this and comes up with a simplified test to use until June 2022 to give at least an indication if the system is good or not. »If you take the famous Newcastle port in Australia, a vessel can wait for a month to enter. Then it is finally your turn, you test the water, it fails and you have to go to the end of the queue and wait another month. Well, I don’t want to be the owner to the charterer about this delay,« Haraldsson paints the picture. fs 40 HANSA – International Maritime Journal 03 | 2021

SCHIFFSTECHNIK | SHIP TECHNOLOGY 3 questions to … Marcus Hummer – CEO Bawat © Bawat »Customers are looking for reliability and ease of operation« What specific demand do you see from the industry? Marcus Hummer: Today, customers are continuously asking for BWM systems that they can understand and operate. Filters, TRO-sensors, chemicals, fragile lamps etc. are something they all would like to avoid as they constantly are creating operational malfunctions and high need for service and spare parts. Customers are looking for simplicity, reliability and ease of operation. Do you have plans to expand your portfolio? Hummer: Our BWMS is a very robust solution based on standard marine components – all known to the vessel crews. Based on heat treatment of the ballast water, the system is then operated without a filter and is completely independent of the water quality it is operated in. That means you have a very reliable system. Single pass is the second advantage, meaning that water is D2 compliant immediately after leaving the system, allowing for operational freedom to either treat during ballasting or deballasting. On ships the heat is usually coming from the waste from the HT cooling system, allowing our system to be operated at nearly zero OPEX. We can also claim, and still look at ourselves in the mirror, that our system is the only true green system on the market. It is sized to the ballast water need of the vessels, and not to the size of the pumps, thus reducing the size compared to competition – smaller system, no chemicals and no OPEX. Our technology is also available in a mobile port based version – relevant for owners with little ballast water treatment need or if they run a fixed »milk run« schedule. Currently, we are in contact with major North European ports to install mobile solutions for treatment in the ports themselves. The solution is also flexible and standalone in its set-up, such that vessels owners can take it with them on voyages if no fixed BWMS is installed. This is typically an advantage for ships with little treatment need – PSV’s, OSV’s etc. What is your expectation for 2021 (and beyond)? Hummer: We have a very positive outlook for the future as we see vessel owners being more and more focused on the operational aspects of a BWMS in their decision making process – both when it comes to ship installations but just as much when a decision to use a port based or mobile system comes in play.
