www.sea-technology.com February 2016 / st 61 vessels. The SOx scrubbers will secure valuable fuel economy. The vessels are container feeders of 1,025 TEU that operate exclusively in Emission Control Areas (ECAs). Since they frequent the low-alkalinity waters between Rotterdam and St. Petersburg, as well as ports like Hamburg with ze- ro-discharge requirements, a scrubber with closed-loop mode was a necessity. The vessels will each receive a hy- brid PureSOx system with multiple in- lets, connecting the main engine and two auxiliary engines to one U-design scrubber. In contrast to earlier systems with multiple inlets, the inlets will now lead into a single scrubber jet section, an advance in construction that will make the scrubber even more compact. The shipyard German Dry Docks GmbH & co. KG will install the sys- tems following deliveries by Alfa Laval in January and February 2016. Thome Group Gets Eco Offce Status Thome Group in the Philippines has become the frst local company to be accredited with Eco Offce certifcation. The international ship manager has successfully completed an environmental audit throughout its Singapore offces to achieve Eco Offce status, which is regarded as the strict- est of its kind in the region. Following a comprehensive audit of a number of Thome Group corporate locations in the Philippines, four Thome Group companies have been accredited: Thome Ship Management Pte Ltd. – ROHQ, TSM Shipping (Phils) Inc., MST Marine Services (Phils) Inc., and Timur Shipping (Phils) Inc. This award recog- nizes Thome Group as an organization that embraces its duty of care to the en- vironment in which it operates. USCG Declines MPN Method to Evaluate UV Tech The U.S. Coast Guard (USCG) has declined the 10(b1) applications to alternatively use the most probable number (MPN) method for evaluating the biological effcacy of UV treatment technologies that had been submitted individually by four ballast water man- agement system (BWMS) manufactur- ers, DNV GL reported. The rationale given by the USCG is that the word- ing in the regulation is live/dead, and that the MPN method does not evalu- ate the performance of a BWMS to that discharge standard. The MPN method evaluates the ability of an organism to reproduce and, hence, its ability to colonize a new environment. As such, it does not provide a result equivalent to that of the USCG's preferred method (vital staining). DNV GL argues the MPN method is the most relevant method and is a reli- able way of evaluating the performance of UV technologies. That method has been validated to a greater extent than most of the methods described in the Environmental Technology Verifcation (ETV) Protocol (prescriptive guidance incorporated by reference to U.S. regu- lation), and UV technologies are com- monly accepted in other water treat- ment industries. DNV GL has provided much of the MPN analysis done for the four BWMS manufacturers and expects the manu- facturers to appeal the USCG decision. A likely consequence of the USCG decision is that the frst BWMS system to be type approved by the USCG will probably be available summer 2016. This will not be a UV system. ST
