The massive container ship that ran aground in the Suez Canal, halting traffic in one of the world's busiest waterways, is still stuck. The ship, called the Ever Given, became horizontally wedged in the waterway following heavy winds. Nearly 19,000 ships passed through the canal during 2020, for an average of 51.5 per day, according to the Suez Canal Authority.
This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.
I am not a computer savvy. My knowledge in programming and robotics and those sort of things is nil. I get lost in the sea of social media and easily entangle myself in the web. All I have done for the last 25 years or so is to pilot ships through the Panama Canal. However, during the last couple of years I have done my best to catch up with technology, since it has enhanced our possibilities and improved safety in our field. But still, I have to admit that I am way behind the new guys in this important issue.
