Education: Effect of Drift Force and unstable moment

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!

This video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

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

With ships as large as 175 feet wide and a channel a maximum of 500 feet wide, how to you safely pass? Former Houston ship channel pilot, Lou Vest, explains how ships fight against hydrodynamics to pass with such narrow margins.

New guidance for PBAs with trapdoors. Released 4.11.2020 at NZMPA Conference in Dunedin, NZ. Distinct difference to suggestions in many other countries, is that we challenge operators who have the ladder suspended from the accommodation ladder (gangway) and not secured to the ship. SOLAS states that pilot ladder shall be secured to the ship, and securing strongpoints, shackles and ropes shall be as strong as the sideropes.

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.

The Seminar aims to inform Member States, intergovernmental organizations and non-governmental organizations in consultative status with IMO about the societal value of maritime pilots and pilotage as a public service. The IMO Secretary-General has recognised maritime pilots as having always been vital to ensuring the safety of navigation in key ports and shipping lanes globally and playing a crucial role in sustaining the global supply chain using specialized knowledge and expertise....

TRENZ proudly present you the next generation portable pilot unit. "SIRIUS" has been redesigned to allow more functionality and precision now and new features in the future. www.trenz-ppu.com SIRIUS Features: High-precision Rate of Turn (ROT) achieved through dual gyroscope and accelerometer integration, utilizing the TRENZ Sensor Fusion algorithm Standard-precision GNSS receiver supporting four concurrent constellations (GPS, GLONASS, Galileo, Beidou) and augmentation via SBAS Advanced AIS/...

The scope of this report covers a twenty-year period between 1999 and 2019 in which there were 1,046 such recorded incidents and where each incident gave rise to P&I liabilities in excess of US$100,000.
