"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
Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...
Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.

Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems. As pilots face this problem throughout every shift they need to put in considerable effort to adjust their work to the many user interfaces they meet.
Join me behind the scenes aboard the pilot boat as we guide the cruise ship Borealis out of the River Tyne and welcome a colossal vehicle carrier into port. In this video, you'll get an up-close look at the challenging conditions at sea, including a rough water pilot transfer as we safely land the pilot onboard. Experience the scale of these incredible vessels and see the precision teamwork it takes to keep everything running smoothly, even in heavy seas. From the stunning departure of the...
