创新型双燃料电力推进+ (DFE+) 推进概念用于液化天然气（LNG）供应链船舶，该概念基于 MAN 49/60DF 发动机和 ABB 动态交流配电和控制系统。通过提高其操作灵活性，有助于减少液化天然气运输船和浮式储存及再气化装置（FSRU）的碳足迹和燃料费用。DFE+ 可使 MAN 49/60DF 在整个发动机负荷范围内以变转速运行。MAN 49/60DF 的效率已经达到同类最佳水平，DFE+ 则进一步提高了效率，并显著减少整个发动机运行图谱内的甲烷逃逸，为符合未来的排放法规开辟了另一条途径。
New Dual-Fuel Electric+ drives LNG vessels to the future
The innovative Dual-Fuel Electric+ (DFE+) propulsion concept for vessels in the liquefied natural gas (LNG) supply chain is based on the MAN 49/60DF engine and ABB’s Dynamic AC power distribution and control system. It helps cut carbon footprints and fuel bills for LNG carriers and floating storage regasification units (FSRUs) by allowing higher operational flexibility. DFE+ enables the MAN 49/60DF to run at variable speed over the entire engine load. While the MAN 49/60DF already has best-in-class efficiency, DFE+ manages to raise this efficiency even further and also significant reduces methane slip over the entire engine map, opening up another path for compliance with future emission regulations.
