Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...

A unique 3D video endeavoring to raise the awareness of the seafarers about a very important, critical, and essential piece of equipment on board. Basic in design, but high on purpose, the mistakes incorrect handling of this equipment continue to result in Near Miss, Incidents and accidents.

A pilot boat is a specialized vessel that is used to transport pilots to and from ships that are entering or leaving port. Pilot boats are typically small, fast vessels that are designed to operate in a variety of weather conditions and sea states.

Consistently 99.9 per cent safe operation of large vessels: Marine pilots on Canada’s West Coast have an exceptional safety record in the world’s largest pilot-mandatory zone for large vessels including oil tankers.
