ProfileInnovative Ship Simulation And Maritime Systems GmbH (ISSIMS GmbH) develops high-level products to increase safety and efficiency in ship operation. Our expertise on Ship-Handling Simulation and Fast-Time Simulation technology has led to unmatched solutions for manoeuvring support.
The developed software tools exceed conventional waypoint planning by creating complete manoeuver plans that max out the ships’ manoeuvring potential. Complex manoeuvres can be monitored and controlled using Multiple Dynamic Predictions for optimal ship handling; and countermeasures can be calculated to avoid roll resonance and wave impact in heavy weather.
These tools are unmatched solutions for
- application in maritime education and training to support lecturing and training for ship handling and manoeuvring. On the one hand it can be used to demonstrate and explain more easily manoeuvring-technology details to the trainee and on the other hand to prepare and perform manoeuvring training in Ship-Handling Simulators and to learn from discussion of the results,
- application on board to assist manoeuvring of real ships e.g. to prepare manoeuvring plans for challenging harbour approaches with complex manoeuvres up to the final berthing/unberthing of ships.

Video Operation of POD Ships - Discussion on Efficiency comparing Conventional and IN-OUT POD strategy
published on 8 June 2022
In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...

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

Video Spiral-Test -Manoeuvre for detailed identification of Yaw Stability using Samples of Cruise Ship
published on 29 September 2021
This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

Video SAMMON Demo Planning FtLauderdale Arrival with comments
published on 20 January 2021
This updated video shows how easy it is to develop an arrival plan with the SAMMON Planning Tool. As a sample the arrival from appraoch until the berth to Ft. Lauderdale is used under strong current of 2kn. At the simulator training courses where we used this tool for preparation of a manoeuvring plan during the briefing sessions all nautical officers involved stated afterwards: "Why don't we have this tool on our ships?"
Video Wind Impact on Ships Turning Motion
published on 20 January 2021
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
Video Fast Time Simulation of manoeuvres - SAMMON

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.
