Engine makers are diligently developing and refining solutions to methane slip, and new attention is focusing on aftertreatment, writes David Tinsley Despite making up less than 2ppm of the atmosphere, methane is responsible for at least one-sixth of the total radiative forcing, a measure of the greenhouse gas (GHG) effect causing global warming. Methane slip […]
UK-based Newport Shipping has signed a letter of intent (LOI) with Zhejiang Energy Marine Environmental Technology (ZEME) in China that aims to further broaden the company’s ability to offer environmental retrofit solutions to customers in the shipping industry. ZEME offers a range of environmental solutions including scrubbers, methanol fuel and alternative marine power (AMP) technology. […]

The Japanese company’s fleet renewal strategy is targeting net-zero emissions by 2050, writes Tom Barlow-Brown. Japanese shipowner NYK Line is increasingly adopting a carbon neutral stance, transitioning its fuel choices to LNG and ordering newbuilds that utilise new environmentally conscious technology. WinGD is the latest to have been picked to provide dual-fuel option for NYK. […]
CROSS-INDUSTRY TEAM TACKLES METHANE SLIP Methane is a potent greenhouse gas, estimated to have a global warming potential (GWP) of 27-30 over 100 years, while CO2 has a GWP of 1 regardless of the time period used. The low-pressure, dual-fuel concept has proved to be the most popular LNG engine technology, but it is also […]
Fjord Line to convert LNG-powered ships to dual fuel The Norwegian ferry operator Fjord Line has decided to turn two of its vessels back from single fuel LNG to dual fuel as a result of unsustainable cost pressures For many years LNG has been seen has one of the primary answers to the need to […]
Raising its game in the wide-bore, medium-speed engine stakes, MAN Energy Solutions has introduced its most powerful dual-fuel, four-stroke engine to date. Spanning the 7,800-18,200kW maximum output range, the 49/60DF design exceeds the larger 51/60DF in potency, while consuming less fuel, such that it is claimed to achieve a class-leading standard of efficiency in both […]
