Video Wind pure drift encounter - practical experiments for getting useful data

published on 8 July 2022

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

Video Yaw Stability of Ships - Basic Principles by Knud Benedict

published on 18 November 2021

Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved

Video Wind Balance on straight track with theory

published on 24 November 2020

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

Video Live test: Backpack & Lifejacket?

published on 30 September 2021

When publishing articles or pictures about pilots and their pilot ladders, very often we see the use of backpacks. The use of backpacks is controversial, since its weight, or buoyancy, can influence the functioning of the lifejacket used.

Video The difference between Gross Tonnage and Net Tonnage

published on 14 July 2020

Using pictures and sketches, this video finally explains the difference between gross tonnage (GRT) and net tonnage (NRT); the ship spaces that are included/excluded in their calculation; and the importance of these terms to ship owners.
Contents of this video will benefit mariners preparing for exams (written and oral examinations).

Video EfficientFlow final conference June 4 2021

published on 10 June 2021

Project results in detail. Efficient port flow using the Port Activity App in the ports of Gävle and Rauma. Sharing time stamps making planning easier for all involved actors. Efficient ship Flow by using a Route distribution service helping pilots better plan meeting points in narrow fairways, saving some fuel but more importantly increasing safety.

Opinion Bow Truster Effect on Ship's Headway

by Capt. Hugues Cauvier - published on 14 July 2022

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

Video Suggestions to improve Pilot Ladder Safety

published on 28 June 2021

Ideas from Nasir Khan, Port Pilot: "I would like to suggest that we try an experiment and make some modifications that will result in a better grip on the handrails of the ship's ladder and on the pilot ladder steps. Let's talk about it!" Modifications: Ships Ladder Handrails & Width of the Pilot Ladder steps. "I analyze the subject of fallen Pilots are two main reasons: -Pilot's hands are losing their grip at the ship's handrails. At transfer point mostly pilots lose their grip on Ships...
