New Dual Fuel, Electric+ (DFE+) concept by ABB and MAN Energy Solutions acknowledged by DNV as a more energy efficient alternative to current conventional designs for liquefied natural gas (LNG) carriers<\/p>\n
The DFE+ solution can help LNG carriers boost energy efficiency by up to 7.5 percent, enabling emissions reduction<\/p>\n
The modular and flexible solution increases cargo capacity by 5 percent<\/p>\n
DNV has quantified the gains that owners of liquefied natural gas (LNG) carriers could expect to achieve using the new Dual Fuel, Electric+ (DFE+) solution developed by ABB and MAN Energy Solutions. Comprising MAN\u2019s four-stroke 49\/60DF dual fuel engine and ABB\u2019s Dynamic AC power distribution and control system, the solution has been developed to overcome efficiency challenges that are specific to the vessel type.<\/p>\n
DNV\u2019s Maritime Advisory assessment concludes that the DFE+ concept is \u201ca competitive and more energy efficient alternative to even the most efficient conventional dual-fuel LNG carrier propulsion designs.\u201d Smaller machinery space requirements could deliver \u201ca conservative estimate\u201d of 5 percent greater cargo capacity. Combined with other steps to optimize performance, the DFE+ concept could contribute to overall energy savings of 6 \u2013 7.5 percent considering the ship\u2019s increased transport work, DNV says.<\/p>\n
From January 1, 2023 the International Maritime Organization (IMO) has required shipowners to report vessels into an Energy Efficiency Design Index (EEDI), an Energy Efficiency Existing Ships Index (EEXI) and an operational Carbon Intensity Index (CII). These tools benchmark ships so that owners know what they must do to meet IMO targets for reducing greenhouse gas emissions.<\/p>\n
As the newest addition to MAN\u2019s four-stroke portfolio, the MAN 49\/60DF engine is optimized for LNG. It is also highly compatible with ABB\u2019s Dynamic AC system, which combines the merits of conventional AC with those of variable frequency to allow the engines to operate on optimal speeds \u2013 significantly improving total fuel consumption.<\/p>\n
“Owners of LNG carriers face specific challenges in complying with the regulations, given their reliance on propulsion solutions with limited potential for efficiency gains,<\/em>” said Prof. George Dimopoulos, Scientific Advisor, DNV<\/strong>. “The ABB \u2013 MAN propulsion concept aims to offer a highly effective way for LNG carriers to meet progressively tightening emissions regulations while also reducing fuel costs.<\/em>”<\/p>\n \u201cWith the current global orderbook for LNG carriers including more than 200 vessels, and emission regulations continuing to tighten, owners need new technologies to meet the requirements that apply to this specific class of ships,<\/em>\u201d said Rune Lysebo, Strategic Market Development, ABB Marine & Ports<\/strong>. \u201cDNV\u2019s testimony on the gains available to LNG Carriers with the new solution developed by ABB and MAN Energy Solutions proves the time is right to explore the next-generation technologies for this vessel type.<\/em>\u201d<\/p>\n DFE+ could be installed with an energy storage solution to operate as a spinning reserve or come coupled with ABB\u2019s Azipod\u00ae electric propulsion. ABB and MAN will also explore integrating fuel cells as the technology matures.<\/p>\n ABB\u2019s<\/strong> Process Automation business automates, electrifies and digitalizes industrial operations that address a wide range of essential needs \u2013 from supplying energy, water and materials, to producing goods and transporting them to market.
