# Hydrostatics Modeling

Hydrostatics modeling is the first step in any stability analysis.  We construct a model of the vessel that includes all relevant details for a stability analysis:

• Hull surface
• All tank definitions
• Locations of all downflooding points
• Sounding tubes for tanks
• Section modulus definition along hull length
• Draft mark offsets

If the model gets used in a damage stability analysis, we add further details:

• Internal compartmentation
• Margin line definition
• Bulkhead locations (for floodable length analysis)
• Damage conditions

Just the stability model can answer many key questions regarding vessel floatation.

1. Hydrostatic properties
2. Tank capacities
3. Tank sounding tables
4. Floodable length curve
5. Longitudinal strength comparison

At DMS, we use the Maxsurf set of stability products.  These products can import GHS and Rhino models.  Plus they bring several other advantages.

1. Visual output to show the exact vessel state
2. Direct program output into MS Word: less time formatting reports
3. Automatic generation of lines plan from hull model
4. Automatic generation of Rhino geometry file from hull model
5. Many more. . .

Efficient hull modeling makes for efficient engineering.

## What is a Stability Test

Stability tests do not arrive instantly after you order one. It takes time and planning, and you should expect extensive coordination with several different organizations. But the ultimate benefit justifies the expense: a ship with reliable stability performance. This article unravels some of the mystery behind a stability test and why you want one.

## Which Engineer

Ships evolved to require a combination of expertise from highly specialized disciplines. If you want a modern vessel, expect a modern team of experts. So let’s meet all the different roles and learn who it takes to create a modern ship.

## Ship Model Scaling

The physics of model scaling make it impossible to perfectly convert between model scale and ship scale. Learn how to get around the scaling correlation problem and convert from model scale to ship scale measurements.

## Next Level Hydrodynamics

Time for an upgrade! Far beyond the single purpose testing facility, the modern towing tank expanded into a Swiss Army knife of experiments. Armed with new gadgets and advanced capabilities. Time to see what new tricks the tank holds for us!

## The Ship Towing Tank

It may look like a swimming pool, but towing tanks exist for a different purpose. Dragging models down the tank propelled the science of ship design forward across the years. These pools deliver critical measurements for ship hydrodynamics. Discover why we pay such a high price for a fundamental tool of ship design.
