How AIS Works - Operation of AIS

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

OHB subsidiary LuxSpace’s satellite for global ship monitoring has reached its target orbit.

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

AIS services are offered by, for example:

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

Over the past few years a number of pilot transfer accidents have occurred resulting from total failure of the side ropes, one school of thought is that the methods of securing a pilot ladder is a factor in such occurrences.

The latest MS Amlin Marine circular, compiled by theTechnical Loss Prevention Consultant Peter van der Kroft, focuses on the importance of pilot safety in marine navigation.

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

This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.

Today I will discuss a very simple and useful practical trick often used by pilots.

When we have to berth a vessel with small clearances forward and aft (say 20 to 25 mtr fwd and aft) it is very essential that you are able to estimate your position. Now most of the time you have a berthing supervisor on jetty who will help you with position.
