Electromagnetic Ship Docking System Debuts

Posted by chrisd on from the can't-dock-with-canoes-though dept.

Makarand writes "A system that uses electromagnets for docking ships is getting ready to be tested at a port in the Netherlands according to this article in the New Scientist. Magnetic docking systems were never used in the past as magnetic fields posed dangers to sensitive cargo like TVs and monitors. Researchers at the Delft University of Technology have developed electromagnets whose magnetic fields do not penetrate far into the ship for this special application. The magnets can be periodically switched off and on rapidly to allow ships to rise and fall with the tide."

  1. So what does the dockworkers' union think? by MacAndrew · · Score: 4, Insightful

    Seriously, in the U.S. we just recently had a paralytic dockworkers' strike. I don't think they'd be amused by this labor-saving innovation. Not that I think people should be kicked out of jobs by robots.

    Each of their mooring magnets generates a 1-tesla magnetic field. (from NS article)

    WOW! That's strong. I used to work with a 1.5-T superconductor magnet, an MRI scanner, and it had a heck of a pull. Enough so that people have been injured or killed when a piece of metal got loose. It took three of us to pull off the base of an IV pole (no one inside at the time). Some of the research magnets are 4-T or more. But these are all superconductors, and act like permanent magnets. The resisitive magnets here must produce tons of heat while gobbling electricity. Surely "auto-dock" wouldn't be too hard to design., with mechanical restraints?
