"Effect of Drift Force and unstable moment"
-------------------------------------------------------------
SAMMON - the IDEAL tool to identify manoeuvring capabilities of a ship - SAMMON - learning the EFFECTIVE way
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!
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
There are many things in both our everyday and professional lives which we take for granted and never question the origins of, an example of this might be the IMPA recommended ‘pilot mark or pilot line’, which is sometimes seen on the side of vessels indicating where a vessels freeboard exceeds 9 metres.
GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.
The Nautical Institute (NI) and the International Maritime Pilots’ Association (IMPA) have been concerned for many years at the needlessly high rate of Pilot Ladder casualties. The NI is continuously reminded of the problem from its Members and through its Mariners’ Alerting and Reporting Scheme (MARS). The issue features frequently in our publications, and we recently dedicated an edition of our award winning magazine The Navigator to the topic, emphasising the importance of good...
Welcome aboard, fellow maritime enthusiasts! Today, we embark on a voyage into the intricate world of ship types. From massive container ships to nimble oil tankers, we'll explore the unique challenges each vessel presents. Whether you're a seasoned sailor or a curious landlubber, our channel will guide you through the fascinating diversity of the ships that navigate our seas. Join us as we delve into the design, function, and complexities of these maritime marvels. Don't forget to like,...
Container ship CMA CGM MISSOURI ran aground in Suez Canal while transiting in southern direction, at around 0930 UTC Oct 14. As of 1745 UTC, probably refloated or moved, several Suez Canal tugs attending. Traffic probably suspended, but it’s not confirmed. No information on what caused grounding.
Container ship CMA CGM MISSOURI, IMO 9679919, dwt 115600, capacity 9448 TEU, built 2016, flag Liberia.
