Recently, the latest development of the Winterthur Gas & Diesel Generation X low-speed diesel engine series, the WinGD X52 diesel engine, has undergone extensive testing and successfully completed factory acceptance (FAT) and witnessed by the eight major classification societies. Type Approval (TAT).
It is reported that this newly certified engine is a five-cylinder version of the Winter Turtle Engine (WinGD) X52 diesel engine with a cylinder diameter of 52 cm. The successful completion of TAT and FAT means that the X52 is ready for commercial use. The test was conducted at Hudong Heavy Machinery Co., Ltd. (HHM), a subsidiary of China Shipbuilding Corporation (CSSC), a licensee of WinGD.
The certification process is carried out on a five-cylinder X52 engine with a speed of 99 rpm and a CMCR (contract output power) of 6408 kW and meets IMO Tier II emission standards. After the test is completed, the 5X52 will be delivered to the CSIC Group Guangzhou Wenchong Shipyard (GWS) to power the 38,000 DWT bulk carrier it is building, and will join the CSSC fleet after delivery.
The X52's FAT and TAT test data is particularly important because the new engine has already won considerable orders of interest. Alexander Brückl, senior engine project manager and WinGD engineer who participated in the test, said: "The X52 engine has proven to be very popular because it is a smart engine, and the major shipyards and their customers are eagerly awaiting FAT and TAT test results. ."
“This rapid market acceptance is based on the reliability and performance demonstrated by the Generation X series of diesel and dual-fuel engines operating to date. Dare to conduct TAT tests on the first engine and fully demonstrate WinGD Self-confidence in engine performance."
WinGD's 5X52 diesel engine is undergoing FAT and TAT testing at the Shanghai Hudong Heavy Machinery Co., Ltd. factory.
Including the test engine, a total of 14 engines have been on the order form. Brückl stressed that the shipowner hopes to achieve significant benefits from the low fuel consumption and low service costs of the Generation X series of diesel engines.
The reduction in fuel consumption is mainly due to the longer stroke configuration of the Generation X series engines, as well as the relatively light construction and the special design for low maintenance costs.
“The long-stroke design achieves higher torque at lower engine speeds than the earlier WinGD engines. Due to the larger diameter, it can use more efficient propellers. At the same time, our designers are also very aware of the engine. The stroke size has a direct impact on the engine height, which in turn has a considerable impact on the cabin size and payload of the ship. Based on market feedback, the cylinder stroke selected by WinGD has proven to be a very common a compromise," added Brückl.
Depending on the market and the agreed conditions, the X-Series engines can also achieve dual rated power values, and this can be done with minimal modifications to the engine and booster sections, allowing ship operators to save on them. Fuel deceleration mode.
It is worth mentioning that the 38,000 DWT bulk carrier built by the W5X52, which has been certified by FAT and TAT, is a special application. Taking into account the requirements of future system integration requirements, Shipowner CS Group has designated a number of advanced digital features for its smart ships in order to achieve maximum ship efficiency and closely monitor and control the shipborne system remotely.
The 13 engines already on the order list are all 6X52 engines and will be built in Korea. They meet IMO Tier II or Tier III emission standards. The Tier III engine is divided into low pressure and high pressure SCR. Eight of the engines, including six 6X52 engines rated at 71.8 kW at 86.9 rpm, use high-pressure SCR for IMO Tier III compliance. The Tier III engine will power six 49,000 DWT petroleum product tankers. The other two engines have the same rated output power and meet Tier II emission standards and will be installed on two 50,000 DWT product tankers.
In addition, six 6X52 engines rated at 8,200 kW at 80 rpm will power five 60,000 DWT series of large open general cargo ships. These equipped low pressure SCR system X52 engines also comply with the Tier III standard.
Representatives from the classification society, including the American Bureau of Shipping, Lloyd's Register of Shipping, China Classification Society, French Classification Society, DNV-GL, Korea Classification Society, Japan Classification Society and Italian Classification Society, witnessed WinGD. FAT and TAT testing of 5X52 diesel engines.
