Wind drift making headway - practical experiments for voyage planning and Rule of Thumb

Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2021-03-08.

Here are described some experiments to get data for voyage planning:
- how to measure wind effects and prepare ship specific diagrams to estimate required drift angles and also rudder angles for wind balance
- to be applied for voyage planning, considering expected operational conditions, specifically for preparing manoeuvring plans for Port arrival and departure planning!
- analysing theses data a simple formula could be derived to calculate the drift angle ß depending on absolute wind speed VA, encounter angle aA and ship speed Vs to:
ß= arctan (CD*(VA +Vs*cos aA)*sin aA)/Vs)
And all this is demonstrated by means of the unique SAMMON Planning software based on Fast Time Simulation of ship manoeuvres...
Enjoy, share and give some thumbs up, if you are satisfied with the movie - and my haircut!

In my experience, a ship moving ahead, rudder amidships, the ship will develop a rate of turn into the wind. However the first manoeuvre on this simulator with rudder midships does not show this, in fact no RoT at all. Quite often at work, I will tell the bridge team I am about to start a turn to starboard/port, order midships and then try to crack a joke about the ship has been here before and knows where to go!!

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. While the type of seabed is of utmost importance during anchoring, soft muddy grounds or clay bottoms are best preferred. It should be taken care that the anchoring bottom is free of power lines, submarine cables, pipelines or rocks. Various methods on anchoring include consideration of...

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

Article The NZMPA Good Practice Guide for Pilots 2021

published on 4 April 2022

The Good Practice Guide for Pilots 2021 describes the knowledge and skills (technical and non-technical) that the NZMPA believe all pilots should aim to achieve and maintain. It is written primarily for pilots for their own guidance and professional development, but can be used as a framework for pilot training, proficiency and assessment. It is referenced to NZ Maritime Law and Codes.
