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.
Floating pilot transfer station for the provision of pilots in the Weser estuary / German Bight sets sail again after a stay of several hours for supplies at Willy Brandt Platz on the Weser. The ship is approx. 61 metres long, 25 metres wide and has a draught of approx. 6.4 metres. It was completed at the Abeking & Rasmussen shipyard in 2010. The catamaran-style hull construction is striking. Slight distortions in the picture are due to the stabilisation in Google Photos.
