Yara Marine Technologies has secured a contract to deliver scrubber systems for a new cruise ship for Saga Cruises, due to be delivered in 2019. Saga has an option for a second vessel.
With a combined engine power of 21.6MW, the vessel’s four MAN engines will each be connected to a Yara Marine Technologies SOx scrubber to clean the exhaust gas emissions to meet IMO’s current, and future, emissions requirements.
Yara Marine Technologies chief executive Peter Strandberg said: “We are proud to announce the contract with Saga and we look forward to seeing this impressive cruise vessel in operation. The decision to install scrubber systems on the vessel reaffirms Yara Marine Technologies’ strong position in the exhaust gas cleaning market.”
Yara has also supplied scrubbers to four of Norwegian Cruise Line’s (NCL’s) vessels Norwegian Jewel, Norwegian Pearl, Norwegian Jade and Norwegian Gem, and for MSC Cruises vessel MSC Fantasia.
The scrubbers for the NCL ships will be Yara’s new Mini Tower inline scrubbers. The multi-inlet scrubber is much smaller than previous versions, by about 20 per cent. Five scrubbers were installed on Norwegian Jewel, one per engine, covering the whole propulsion system. Collectively, they are capable of reducing Sox emissions to air by up to 99 per cent. They also reduce particulate emissions to the air, by 85 per cent. They were installed over a two year period starting in 2014, while the ship continued in service.
The scrubbers also feature a water membrane filtration unit. This water cleaning system uses ultrafiltration technology to clean the recirculated water to clear water during the closed loop operation. The by-product is collected and removed in drums.
Yara’s multi-inlet inline SOx scrubber system can deal with multiple engines. Yara’s installation of the multi-inlet scrubber, which has received International Air Pollution Prevention (IAPP) and MEG G certificates from class society DNV GL, covers three engines.
On the NCL ships one scrubber has been used rather than three. The space requirements are therefore considerably reduced, with a 67 per cent reduction only using one scrubber and an additional 20 per cent reduction as a result of using the mini scrubber.
Yara also won a contract to supply scrubber systems on four newbuild container feeder vessels for German shipmanager Jüngerhans Maritime Services. Delivery of the first vessel is expected by the fourth quarter of 2017.
With Yara scrubber systems installed, the ships can operate on heavy fuel oil with a sulphur content of up to 3.5 per cent and will be compliant with both present and future IMO regulations. Yara said in a statement that Jüngerhans’ new vessels are “future-proof with respect to the new global sulphur cap.” Yara has designed and contracted more than 100 scrubber systems since 2011.
In another development Yara can install a dual SOx and NOx cleaning operation on the same engine. Yara installed its solutions on two Yara Group-owned liquefied petroleum gas carriers, Yara Kara and Yara Nauma, and will also be installed on a third vessel. This is the first time that NOx and SOx emissions solutions have been installed together on the same engine on a commercial transport vessel.
