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...

Theory on Wind drift will be shown together with demos using SAMMON planning on the effect of thrusters to have some effect on drift speed & direction

Article MARS-Report: Paltry PPU position predictor

by The Nautical Insitute - published on 18 August 2023

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

Video S-100 Services for Safe & Optimized E-Navigation

published on 27 August 2020

“The world of hydrography is going digital and the S-100 standard is an essential component of that move.” See how the Canadian Hydrographic Service has led Canada to become one of the first countries in the world to start using the S-100 standard, and how implementing these standards will benefit Canadians through increased safe navigation in Canadian waters.

Article Study: Correlation Evaluation of Pilots’ Situation Awareness in Bridge Simulations via Eye-Tracking Technology

published on 21 January 2022

Improvements to pilots’ situation awareness (SA) in maritime navigation are critical to reducing human errors, which have caused 75% to 96% of marine accidents over the last few years.

Article 1,000 Combinations around - Which one is correct?

by Arie Palmers, Netherlands - published on 22 October 2020

Before you, you see my third article on pilot boarding arrangements. After my two previous articles ‘1000 ways to secure a pilot ladder’ and ‘1000 ladders around’, I have received a lot of feedback and also questions to get deeper into the matter of combinations and embarkation platforms.
