In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
Dali Timeline What's Going on With Shipping? March 29, 2024 In this episode - maritime historian at Campbell University (@campbelledu) and former merchant mariner - discusses the timeline released by the NTSB from the Dali's Vessel Data Recorder and lays out some of the questions, issues that have been raised, and questions that need to be answered. #dali #baltimorebridge #baltimore #shipping #brdigecollapse #supplychain #containerships #containerships Support What's Going on With...
