Hull Design & Fairing

The design of a vessel in Orca3D begins with the hull model. Hull design is a unique combination of artistic expression and engineering analysis, combining to form a creative process to meet the aesthetic and performance requirements of the vessel.

The software that you use to transform the hull from an idea to a 3D computer model should enrich the creative process, with guidance provided by precise and detailed analyses. With Orca3D, you have complete freedom to create any type of hull, beginning with a concept and carrying through to final fairing, while ensuring that the hull meets your target hydrostatic properties.

In Orca3D, the hull is created as a NURBS surface. While Rhino provides many important surface creation and editing tools, Orca3D adds capabilities that are specific to hull design, such as:

 

  • Hull Assistants, for instantly creating hulls according to a range of input dimensional and shape parameters

  • Easy definition of the sections to be displayed on your hull surface; stations, buttocks, waterlines, and other planar curves. The user may specify the color of these sections, together with the layers upon which they should be placed.

  • Real-time update of the sections as the hull surface is modified

  • Real-time update of the hydrostatics as the hull surface is modified

  • Control over the shape of the forefoot of the hull, ensuring a curvature-continuous transition from the stem to the bottom

  • Easy positioning of the surface's control vertices, either interactively, or via Orca3D's vertex control dialog

 

Any type of hull and hull feature may be modeled. Hulls may be created as a single surface, or when appropriate, multiple surfaces. Tools like blending, trimming, and filleting provide tremendous capability and flexibility.

An example of a large commercial ship. This model consists of three surfaces; the hull, the deck, and the transom. Note the integrated bulbous bow, perfectly faired into the main hull, since it is all part of the same surface.

Chine hulls are easily modeled and analyzed, with as many chines, knuckles, or style lines as desired.

This sailboat model shows the importance of a smooth transition from the stem to the bottom; not just slope continuity, but also curvature continuity. Orca3D makes it simple to ensure this higher degree of fairness.

 

In addition to hull fairing tools, Orca3D provides a new tree control to help you to organize your model. It's another view into your layers, but with the addition of individual objects. This makes it easy to name objects, select them, change their properties, and drag them from one layer to another.

Another nice feature of the tree is the ability to quickly focus in on part of the model; simply right-click on a layer, sublayer, or object, and select "Set View Part." The rest of the model will then become hidden.

 

 

 

 

"How fast will it go?" The Orca3D Speed/Power Analysis module has two different prediction methods: the Savitsky method to predict the speed/power curve for chine hulls, and the Holtrop method to predict the speed/power for displacement hulls. We have integrated theHydroComp Drag Prediction Library, to ensure reliable, accurate results.

Most of the required input parameters are automatically computed from your model, although the user can input or override the values. Results are quickly generated and professionally formatted, and include checks to ensure the validity of the results. Any parameters that are outside of the ranges of the prediction method are flagged.









Analysis reports

The results of the analysis are presented in easy-to-read reports, which include a summary of input data, checks of the parameters of your design versus the limits of the analysis method, and performance data versus speed. Plots of various parameters are also included, and the entire report may be printed or exported to Microsoft Excel or PDF.

In addition to predicting the performance, the analysis gives insight into how to improve the performance, with a Drag Reduction Analysis. Four key parameter are evaluated, and recommendations given on adjustments to optimize your design; Planing Beam, Deadrise Angle, LCG location, and Shaft Angle.








Weight/Cost Tracking


The success of any design hinges on its weight and center of gravity. These parameters are fundamental to stability, speed, capacity to carry cargo (whether it be passengers, containers, or weapons), seakeeping performance, etc. Weight and CG tracking therefore must be a fundamental part of any design process.

Cost is another critical factor in the success of a design, and good engineering practice calls for cost considerations to be closely tied to the design process.

Orca3D's Weight/Cost Tracking module adds value to your Rhino model by assigning weight and cost parameters to the objects in the model, and summarizing and presenting the data.

For example, a surface that represents a portion of the hull can be assigned a weight per unit area, and as that surface is modified, the total weight and center of gravity updates automatically. The cost parameter is broken down into material cost and labor cost, and can also be assigned on a per unit area basis. Similarly, curves can be assigned values on a per unit length basis, and solids can have either per unit area or per unit volume values. Also, curves, surfaces, and solids, as well as point objects, can be assigned an absolute value for weight and/or cost, that will not change as the object is modified.

To simplify the process of assigning weight and cost values to your objects, Orca3D includes the ability to create a library of stock materials, and you can assign a stock material to the objects in your model. For example, you might create "5 mm steel plate," with a unit weight per square meter, a material cost per square meter, and a labor/fabrication cost per square meter.
