Combined abatement installation for Yara LPG carriers
The two ships built at Hyundai Mipo Dockyard in Korea have both been equipped with SOx scrubbers and Selective Catalytic Reduction (SCR) systems in order to comply with the IMO 0.1% ECA requirements.
Yara said this is the very first time both technologies have been proven to successfully work at the same time on a marine vessel in operation.
Kai Latun, chief marketing officer, Yara Marine Technologies said: “Yara Kara and Yara Nauma are testaments to Yara’s unique position in the marine exhaust gas cleaning market as a complete abatement specialist, demonstrating on these operating ships their capabilities to also successfully run a dual SOx and NOx cleaning operation.”
He added that there were technical challenges that had to be overcome before successful commissioning with the most demanding issue being to combat the exhaust gas composition and density changes caused by running the two abatement systems in parallel.
“As with all new technological developments, you are doomed to have an equal amount of challenges, but all issues where quickly resolved during the commissioning of the first vessel and all systems are working perfectly together,” he said.
The engine specifications on both vessels include three diesel generator engines (1.32MW*900rpm each) and a Main Engine (ME) 7.62(MW*115rpm) that are connected to one, single inline scrubber.
They have also been equipped with SCR systems to effectively reduce nitrogen oxide from the exhaust and are certified to meet IMO NOx Tier III regulation requirements.
Later in the autumn a third sister vessel will also be completed with the same technical specifications.
