Maxsurf 2

Maxsurf 2

This is the second course in our Maxsurf series, and it focuses on three key modules: Maxsurf Modeler, Maxsurf Stability, and Maxsurf VPP, guiding you through the core tools used in hull modeling, stability analysis, and performance prediction.

– MODELER

Although we explored Maxsurf Modeler in detail during the first course, there’s still one important step ahead: designing a vessel directly in Maxsurf Modeler from scratch—without relying on a Lines Plan as a guide—while applying core principles of naval engineering.

– STABILITY

We will use the model we designed—alongside others—to carry out all hydrostatic calculations using hull sections precisely generated in Maxsurf Modeler. This approach will let us factor in shell thickness for the hull and any tanks and compartments defined within it.

We will perform several types of analysis, such as:

1. Upright Hydrostatics: Calculates the vessel’s hydrostatic properties across a range of draughts at a fixed trim. It generates standard hydrostatics data along with tabulated form data for each draught.

2. Large Angle Stability: Calculates the righting lever (GZ) curve over a range of heel angles and checks it against selected stability criteria. It takes into account the vessel’s current loading and any defined damage scenarios.

3. Equilibrium Condition: We will determine the vessel’s equilibrium position based on the current load and damage cases. We will also be able to consider grounding and wave profiles. This analysis is especially useful for assessing the impact of different damage scenarios or running detailed simulations.

4. Specified Condition: Calculates the vessel’s hydrostatics based on either a specified displacement and center of gravity or specific fore and aft draughts. It’s especially useful for precise simulations—for example, when you need accurate hydrostatic data during an inclining experiment.

5. KN Values: Calculates KN values across a range of displacements and heel angles. You can specify different heel angles than those used in other analyses like large angle stability or limiting KG. The results are the cross-curves of stability.

6. Limiting KG: Calculates the maximum allowable vertical center of gravity (KG) at which the vessel still satisfies the selected stability criteria. You can define the range of heel angles and displacements to be considered. Note that the heel angles used here can differ from those used in the large angle stability or KN (cross-curves) analyses.

7. Floodable Length: Determines the maximum length of the vessel that can be flooded without compromising compliance with the selected stability criteria. This analysis helps assess the vessel’s survivability and compartmentalization requirements in the event of hull damage or water ingress.

8. Probabilistic Damage: Calculates the attained index representing the overall probability of survival by evaluating a range of combined damage scenarios.

9. Longitudinal Strength: Performs calculations of longitudinal loading, shear forces, and bending moments to evaluate hull-girder stresses.

10. Tank Calibration: Generates detailed calibration tables and graphs for tanks.

11. MARPOL Oil Outflow: Calculates potential oil outflow from damaged tanks in accordance with MARPOL regulations—specifically MEPC.141(54) Regulation 12A on oil fuel tank protection and MEPC.117(52) Regulation 23 on accidental oil outflow performance.

12. Cross-Flood: Calculates the cross-flooding time in accordance with MSC.362(92).

– VPP

Finally, we will take the sailboat modeled in Maxsurf 1 and evaluate its performance under various sailing conditions using the Maxsurf VPP module.

What will you learn?

• Model a vessel from scratch using Maxsurf Modeler, applying both the modeling techniques introduced in the first course and naval engineering design concepts.
• Perform detailed hydrostatic analyses in Maxsurf Stability by working with accurately generated hull sections from the surface model, understanding the required input data and how it must be configured.
• Estimate the sailing performance of the yacht modeled in the first course under different navigational conditions using Maxsurf VPP, gaining insight into the necessary inputs and how they affect both analytical and graphical results.
• Interpret and validate results across all applications by completing hands-on practical exercises.
