Wärtsilä X72 two-stroke diesel engine successfully passed the test and delivered

Recently, Winterthur Engine Co., Ltd. (WinGD) and Korea Hyundai Heavy Industries Group jointly announced that the first ICTIL III X72 two-stroke diesel engine that meets the IMOTier III specification has successfully passed the test and delivered.

According to the sixth item of the Annex of the MARPOL Convention of the International Maritime Organization, for the 13th item of NOx emissions, ships with keel laying time after January 1, 2016 need to meet IMO when driving in Emission Control Areas (ECAs). Tier III emission specifications.

On March 23, less than three months after the implementation of IMOTier III, Winterthur Engine Co., Ltd. (WinGD) and its main engine manufacturer Hyundai Heavy Industries Group's Engine Machinery Division (HHI-EMD) jointly announced the first The IWCII X72 mainframe, which complies with the IMOTier III specification, has successfully passed the test run and has been delivered.

It is reported that this Wärtsilä 6-cylinder X72 mainframe is equipped with a compact selective catalytic reduction (SCR) system before the supercharger. The system, provided by HHI-EMD, has been experimentally verified that the nitrogen oxides emitted by the mainframe meet IMO Tier III emission standards, allowing ships loaded with the system to operate in emission control zones (ECAs). Also verified by the test, the Wärtsilä X72 mainframe can meet the emission standards of nitrogen oxides in the Tier II area without the need for a post-processing unit.

For its supercharger front SCR system, HHI-EMD explained that placing the SCR catalyst in the front of the hotter supercharger ensures the temperature level required for the urea solution to mix with the exhaust gas during the denitration catalytic reduction.

In addition to the staff of WinGD Korea and HHI-EMD, the participants from the American Bureau of Shipping (ABS) Korea Branch, Korea Classification Society, Hyundai Sanhu Heavy Industry and SeaQuest Marine Project Management participated in the test. After the test run, the main engine (15,080kw / 74.7rpm) was successfully delivered to Hyundai Sanhu Heavy Industries in Korea and will be installed on a 159,000 dwt crude oil wheel later. The IMO Tier III-compliant tanker will be allowed to enter North American and Caribbean waters, the first emission control zone (ECA) to be announced on January 1, 2016, when IMOTier III is in force. The vessel will be one of the first ships to meet IMO Tier III emissions requirements when it is operational in the US and Canada.

Mr. Thomas Werner, Project Manager of Tier III in WinGD R&D, pointed out: "This demonstration of the ability of the WinGD two-stroke mainframe to meet the IMOTier III emission standards clearly demonstrates that WinGD and its mainframe manufacturers are fully prepared to build on the shipowner's emissions. The main engine in the control zone. Therefore, when it is necessary to trade in the US and Canada, this tanker equipped with the Wärtsilä X72 will be the first vessel capable of operating in the IMOTier III area."
