- Draft and basic hydrostatic values (displacement, LCB, VCB, LCF, KMT, KML, etc.)
- Intact stability analysis (rules implementation and evaluation)
- Damage stability analysis (damage combinations)
- Max VCG searches, for intact or damage stability
- Floodable lengths
- Many more
Why GHS TutorialsThe allure of GHS is its flexibility. It gives the user complete custom control over their analysis. However, this flexibility also lends to a high learning curve. Creative Systems (makers of GHS) do offer training in GHS. But often, this does not help new engineers. There are many reasons why new engineers don’t get training. Perhaps the company can not afford it at the moment. Or maybe the class is not available for 6 months, and project work must continue. Too often, engineers have learned GHS simply by reading through the reference manual. Reference manuals do not provide the structure and layered introduction necessary for training in new software. Too help out all new GHS users, DMS provided a series of video tutorials, which introduce the main elements of GHS. This will not cover all the features of GHS, but it will provide 90% of everything you should know for basic project work. All the tutorials include videos and homework files that let you practice your skill sets. The tutorials are divided into several categories and each video covers a specific subject. They are intended for people to work through them sequentially. Click on the links below for each category.
Basic hydrostatics for the vessel. How to set vessel conditions, including draft and trim, adding weight, loading tanks, etc. Also covers the status command, and its many options. Completes with the GHS command and all the information covered in its standard hydrostatic table.
Introduces the limits command to apply regulatory limits. Covers generation and use of the GZ curve. Explains the various types of heeling moments possible in GHS. Provides detailed explanation of how to code the IMO severe wind and roll criteria. Finishes with the MaxVCG command.
Meet the AuthorThese tutorials are published by Nicholas Barczak and represent his knowledge and experience with GHS. He has worked with GHS for over seven years in a variety of applications including:
- Fishing vessels
- Work vessels
- Passenger vessels
- Research vessels
- Heavy lift transport vessels
- Small military vessels (under 6.0 m)
- Specialty vessels
- Numerous concept designs
- Initial concept evaluation
- Floodable lengths
- Longitudinal strength
- Intact stability analysis (USCG, IMO CCG)
- Damage stability analysis (USCG, IMO, CCG)
- Numerous specialty applications.
There is still plenty I can learn about GHS. But I believe I have used it enough to learn its strengths and weaknesses.
