MOL’s windshield for boxships cuts CO2 emissions by 2%

Japan’s Mitsui OSK Lines (MOL) has carried out tests on a windshield it has developed for containerships and claims the device cuts CO2 emissions by 2%.

The shield has been installed on the bow of one of its boxships, MOL Marvel, and test results show the vessel had a 2% average CO2 reduction sailing at 17 knots on a transpacific route, compared to operating an identical vessel at the same speed without the device installed.

“MOL continues efforts to confirm the windshield’s seaworthiness and sailing data analysis, and looks forward to more advanced technological development based on this research project,” the company said in a release today.

  1. It’s maybe nitpicking, but it’s very annoying when so-called ‘industry experts’ use such expressions as “17 knots per hour”.

    A knot is a speed of 1 Nautical Mile per hour.

    “Knots per hour” is incorrect.

    1. Thanks Capt. B, we took it out as you’re quite correct. We better inform MOL! 🙂

  2. Very pretty. But there is a reason for the breakwater fitted ahead of the first container stack, Unless that “windshield” has the same sort of scantlings as the breakwater, it will not be there fore very long.
