Schiffstechnik | Ship Technology cording to Gard, procedures for training and familiarisation with the BWM Convention should be incorporated in the company’s safety management system (SMS). In September 2018 already Japanese classification society ClassNK announced its recommendation to install as early as possible. In its own fleet of 7,315 ships which are obligated to install BMWS, only 1,915 ships had completed the installation by the end of August. On the product side, there has been some movement recently. Classification society American Bureau of Shipping (ABS), with quite a lot of knowledge about the U.S market, revealed at the end of 2018 that now 13 systems received approval from the United States Coast Guard. (HANSA presents a comprehensive list of manufacturers, products and approvals on the following pages of this issue.) Issues? Yes, but … In a recently released survey, ABS found that just over a third of installed management systems to be fully operational. The survey integrated feedback from more than 60 shipowners and almost 500 ships – including seven main types of systems supplied by 22 different vendors. In general, about one third of the participants claimed to be happy with the reliabilty. However, this implicates that this aspect remains a concern for a big share of ship owners. Two thirds of the respondents saw their installed system inoperable (6%) or operationally problematic (59%). Several said, that more crew training was neccessary. On a financial argument, just 22% of respondents said they were happy with the OPEX they were experiencing, suggesting it was above the estimates provided by the manufacturers. Global survey of existing BWTS: Chosen technologies included •• Filtration + Side-stream EC + Neutralization (29%) •• Filtration + UV Treatment (20.7%) •• Ozone Treatment + Neutralization (19.9 %) •• Filtration + Full Flow (In-line) EC + Neutralization (17.8%) •• Full Flow (In-line) EC (7.5%) •• Filtration + Chlorination via chemical addition (5%) •• Filtration + Deoxygenation (0.2%) The Ballastwater Equipment Manufacturers’ Association (BEMA) – formed in April, 2018 signed up nearly forty members last year. »With that voice, we want to speak to you today to remind each of you that the compliance dates are rapidly approaching«, BEMA president Mark Riggio emphasized. HVS_Konzert_Anzeige136x209mm_DVz.indd 1 14.02.19 08:23 The last possible minute Talking virtually to all shipowners, Riggio emphasized: »Have there been issues with the early designs of Ballast Water Management Systems? Absolutely. Can a Ballast Water Management System be difficult to operate? Yes. Will a Ballast Water Management System affect the normal, pre-ballast water treatment operations of your vessels? Definitely. All of these questions have led many of you to delay this decision until the last possible minute in order to optimize your best chance for success. While we understand that thought process, we want to caution you that it is already the last possible minute.« n 48 HANSA International Maritime Journal – 156. Jahrgang – 2019 – Nr. 3
