PIAS module: Hydrotables
Many PIAS modules, such as Fairway, Layout or Loading, offer fancy GUI’s or fine graphical depictions in their output. Not so for Hydrotables. Nevertheless, this module for the generation of dull stability-related tables and graphs play a vital role in when compiling stability booklets, with these capacities:
- Hydrostatic tables.
- Cross curves and diagrams.
- Bonjean tables.
- Deadweight tables and deadweight scales.
- Tables of wind heeling moments.
- Tables and diagrams of intact maximum allowable VCG. Based on a wide variety of stability criteria, e.g. according for seagoing commercial vessels (Intact Stability Code), naval vessels, offshore units, inland waterway vessel, fishing vessels, unmanned pontoons etcetera. For a full list please consult the manual at https://www.sarc.nl/images/manuals/pias/htmlEN/stabcrit.html#stabcrit_criteria
- Tables and diagrams of maximum allowable VCG in damaged condition, also according to a wide range of commercial and naval international damage stability criteria, see https://www.sarc.nl/images/manuals/pias/htmlEN/stabcrit.html#stabcrit_standard_requirements
- Curve of floodable lengths.
- Tables of maximum allowable grain heeling moments, according to the rules of the International Code for the safe carriage of grain in bulk, IMO res. MSC.23(59).
- Van der Ham’s trim diagram, a nice graph which shows in one glance the relations between drafts, trim, displacement and LCG.
- European inland waterway (IWW) tonnage tables, according to the Convention on the measurement of inland navigation vessels, Geneva 1966, which applies to all European IWW ships today.
Although these tables have their own purpose and background, they are still integrated in PIAS, because of common settings for draft and/or displacement ranges, trim ranges etc.
Furthermore, at SARC we understand that no single PIAS user will need all these functions, which is the reason that Hydrotables is based on a licensing system where each user only acquires those functions which are actually needed by the company or for the design task at hand.
