Yara Marine Technologies has successfully delivered, commissioned and certified a mini SOx scrubber with
35% reduced height for two of Hyundai Heavy Industries LPG carriers, Yara Kara and Yara Nauma.
The mini scrubber systems built at Hyundai Mipo Dockyard, have received both the IAPP and the MEG G certificate from DNV-GL and meet MEPC 259 (68) requirement – successfully cleaning Sulphur Oxide emission from 3,5% down to 0,1% adhering to the IMO’s strictest requirements.
A unique design of the Yara mini scrubber allows for a substantially smaller and more compact model then previously seen operating a 7,6MW engine, with a height of only 8.5 meters. Furthermore, the design functionality of the mini scrubber allows for flexibility to shorten and widen or prolong and decrease the scrubber tower as the ship owner see fit in order to efficiently cater for the specific space available on the vessel.
The two already operating vessels are equipped with two scrubbers serving the three diesel generator engines (1.32MW*900rpm each) and a Main Engine (ME) 7.62(MW*115rpm), where one scrubber is connected to the ME and the last scrubber is connected to the three auxiliary engine exhaust system.
Yara Marine has also successfully installed mini scrubbers on four of Norwegian Cruise Lines (NCL) vessels; Jewel, Pearl, Jade and Jem, all with engine capacity of 14,4 MW and scrubber towers measuring 10 m height and 2,8 m in diameter. The fitting of the NCL vessels were all done while in service and no valuable commercial sailing time was lost.
According to Chief Sales and Marketing Officer at Yara, Mr Kai Latun, space availability is a critical factor when designing exhaust gas cleaning technology for the marine segment.
“Space requirements are of huge concerns to all ship owners and by reducing the size of the scrubber tower and also increasing size flexibility, we can offer a much more flexible product than our competitors”, Mr Latun explains.
“The mini scrubber is actually designed around the specific vessel’s space availability and not the other way around, and this makes us able to cater for ship owners with even less space than usual”, Mr Latun concludes.
Later in the autumn a third sister vessel to Yara Kara and Yara Nauma will also be completed with the same technical specifications.
