Greenhouse Gas (GHG) reductions of up to 21% are achievable now from LNG as a marine fuel, compared with current oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW).An independent study report confirms that emissions of other local pollutants, such as sulphur oxides (SOx), nitrogen oxides (NOx) and particulate matter (PM), are close to zero when using LNG compared with current conventional oil-based marine fuels.The study, commissioned by SEA\LNG and SGMF, was conducted by leading data and consultancy provider thinkstep according to ISO standards. The report, which has been reviewed by a panel of independent academic experts…

A team led by Northrop Grumman Corporation has won a $5.4 million contract from the Defense Advanced Research Projects Agency (DARPA) to determine the feasibility of using supercavitation technology for stable, controllable, high-speed underwater transport. The Underwater Express program is a DARPA technology research and evaluation program to establish the potential of a new technology. Supercavitation creates a gas cavity between the vehicle surface and the water, thereby reducing drag and increasing vehicle speed. The program's ultimate goal is a new class of underwater craft for littoral missions that can transport small groups of Navy personnel or specialized military cargo at speeds up to 100 knots.
