Spiral-Test -Manoeuvre for detailed identification of Yaw Stability using Samples of Cruise Ship


published on 29 September 2021 92 -

Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2021-09-01.
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. Finally, a discussion of of ship’s hull form with loading conditions and elements like appendages completes the overview on effects of Yawing stability.
The next videos to follow will demonstrate other manoeuvres (e.g. Pull-out Test and Zig-Zag Test) which are also helpful to identify and discuss the stability condition for ships and the different aspects contributing to yaw stability.

Video How Ship Anchor Works? - Procedure For Anchoring a Ship at Sea

published on 11 July 2020

#Anchor #shipanchor #windlass Anchoring is one of the very frequent operations onboard ships. A number of variables and external factors influence the duration and location of an anchoring operation.

Video Ex chief pilot of Bremerhaven harbor pilots on 400 meter ships (German with subtitles)

published on 1 February 2023

Matthias Meyer was head of the Bremerhaven port pilots, nautical expert and lecturer at maritime schools. In front of our camera, he voices what has long been a topic of discussion in shipping circles: that the 400-meter container ships have simply become too big for the narrow shipping channels of the Weser and Elbe. In his view, a serious accident is only a matter of time. We take a look at how the district is dealing with these giants and what politicians, BUND and shipowners have to say...

Video Waterford Pilot boat, day of launch & ship boarding trials

published on 11 October 2021

Here's a cool little video of 'PORT LÁIRGE', the Port of Waterford’s new pilot boat we've just launched and it was wonderful to have built another pilot boat for Ireland. She's our 15m Interceptor 48 pilot and is the 48th pilot boat we’ve supplied to ports globally. Powered by a pair of Scania D13 500hp engines she has an operational speed of over 25kts and is capable of carrying of 5 pilots and 2 crew in fine comfort. I think she looks just fabulous in red and blue and look forward to...
