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 edited for discussing alternatives or optimisation purposes. The last sample is the arrival manoeuvre in the Port of Rostock with a POD ships under strong Wind. It could be demonstrated that with going stern first the manoeuvre can be much more effective - faster and even possible for higher wind speeds.
This demonstrates the advantage of a POD acting with SFM now at the fore end of the ship seen in the direction of motion and working directly against the wind - This enables smaller drift angle, specifically if the bow thruster at the other end supports holding the ship against the wind.
The final sample is sort of provocative - showing a movie with departure manoeuvres of many ships as a "Port Miami Fashion Show" where the idea came to me why these ships are not immediately leaving the port directly with stern first - in contrast to go first into the harbour to turn the ship and then heading to the open sea…

Video Fast Time Simulation of manoeuvres - SAMMON

published on 24 November 2020

This video shows the underlying principles of the SAMMON software tools based on Fast Time Simulation of manoeuvres. It describes very shortly some of the features for manoeuvring planning and conning / monitoring with danymic prediction which are shown in more detail in the other movies on this channel.

Video Wind Balance on straight track with theory

published on 24 November 2020

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

Video How Ship Anchor Works? - Procedure For Anchoring a Ship at Sea

published on 11 July 2020

#Anchor #shipanchor #windlass Anchoring is one of the very frequent operations onboard ships. A number of variables and external factors influence the duration and location of an anchoring operation. While the type of seabed is of utmost importance during anchoring, soft muddy grounds or clay bottoms are best preferred. It should be taken care that the anchoring bottom is free of power lines, submarine cables, pipelines or rocks. Various methods on anchoring include consideration of...

Video Ex chief pilot of Bremerhaven harbor pilots on 400 meter ships (German with subtitles)

published on 1 February 2023

Matthias Meyer was head of the Bremerhaven port pilots, nautical expert and lecturer at maritime schools. In front of our camera, he voices what has long been a topic of discussion in shipping circles: that the 400-meter container ships have simply become too big for the narrow shipping channels of the Weser and Elbe. In his view, a serious accident is only a matter of time. We take a look at how the district is dealing with these giants and what politicians, BUND and shipowners have to say...

Article New Study on GNSS Interference in the Baltic Sea

by GPSPATRON Sp. z o. o. - published on 12 March 2025

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.

Video How Stabilisers Reduce A Ship's Roll

published on 4 July 2019

Stabilisers are used to reduce the amount of roll experienced by large ships.
In this video, we look at a few different stabilisation techniques. We investigate how different methods work and how successful they are at reducing a roll.
