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.

In a navigation incident, the first line of inquiry would normally cover the bridge watchkeepers. While the human element plays a significant role in these incidents, it is perhaps worth asking, what if some geographic areas are more prone to navigation incidents than others?

Article An Analysis of Pilotage Marine Accidents in Korea (2019)

published on 18 August 2020

Since the late 2000s, a debate has been sparked on the most suitable age of retirement for Korean pilots. The debate has focused on the extension of retirement age of pilots from 65 to 68 and whether this will affect the probability of marine accidents.
