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.
CMA CGM Columbia container ship arriving from Shekou port, and transiting thru Hong Kong, destination Singapore
a rare capture of TWO harbour pilots boats to carry two pilots leaving off the container ship
Columbia is only a 300m long 48m wide vessel, only 9200 TEU capacity but it has separate bridge tower and chimney. The ship was built in 2015.
Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems. As pilots face this problem throughout every shift they need to put in considerable effort to adjust their work to the many user interfaces they meet.
