First WinGD iCER on-engine solution ordered for LNG carrier
By Becky Schultz05 August 2022
WinGD’s first order for its iCER on-engine solution will be delivered as part of a WinGD X-DF 2.1 engine for a new 17400 cbm LNG carrier. The carrier is being built by Hyundai Heavy Industries (HHI) in South Korea, with the on-engine iCER scheduled to be delivered to HHI in May 2024.
The on-engine iCER (intelligent control by exhaust recirculation) is designed to provide a compact, easy to install option for reaching the lowest emissions possible with low-pressure, dual-fuel engine technology, said WinGD. The solution being delivered for the carrier was developed in collaboration with HHI’s Engine & Machinery division. It features second-generation X-DF technology for greater combustion control that translates to lower emissions and fuel savings across the load range, WinGD asserted. The integrated engine package can be installed as a single unit at the shipyard, which the company said simplifies testing and commissioning.
“Since their introduction seven years ago, X-DF engines have established a remarkable track record of reliability and efficiency. The addition of iCER has built on this success and now the on-engine iCER adds another configuration that will enable us to support our customers in their efforts to decarbonize their operations with lowest CAPEX,” said Dr. Carmelo Cartalemi, global head of sales at WinGD.
According to the company, the X-DF2.0 engines with iCER technology can improve fuel consumption by approximately 8% in gas mode and 6% in diesel fuel mode, while meeting IMO’s Tier III NOx regulations in both. Methane slip can be reduced by as much as 50%. Exhaust gas recycling can be used across the full engine load profile in both gas and diesel modes.
“These improvements mean that the full power range is available using gas fuel in all modes of operation, unlike other exhaust recycling solutions,” said Cartalemi. “Thanks to our close cooperation with HHI-EMD, we have added to the operational flexibility that has already made fuel-flexible WinGD X-DF engines the standard choice for twin-engine LNG carriers.”
