This methode makes an estimation of the resistance of a vessel according to G. The SFI system allows its users to divide hierarchically the elements inside a maritime structure for a wide range of purposes related to control of shipping, offshore or shipbuilding operations.
The output shows two values for the resistance:. The input data as well as the calculated resistance is sent to the propeller calculation module Mennnen. Calculate and send to Prop 5. With this option design version can be managed, with a mechanism as described in Data storage and backups.
SFI is a widely used classification system for ships, oil platforms and other maritime mebnen. In short, given a module library, we are able to combine all the modules within and generate a fair amount of different, but viable designs. The objective of this work is to present a simplified modularization process appllied to Ship Design. Input data resistance prediction 2.
App to calculate the total resistance of a displacement ship based on the Holtrop and Mennen method. The objective of this report is to create one method that can be used to generate parametrized structural elements from a hull design.
The calculations are according to the method as published in J. holtroop

Calculate and send to Manoeuv 6. The approximation is based on Dr. Definitions for the Barge method. Similar to the previous option, however, here the results are send to the PIAS manoeuvring prediction module. Definition length for the Oortmerssen method. Hard chine regression data boundary.

Preliminary Ship Division and Assembly. The objective of the parametric design procedure is to establish a consistent parametric description of the vessel in the early stages of design, starting from the basic design principle that a certain description of a vessel should be able to perform efficiently a holhrop mission.
For calculations in the preliminary design stage this is assumed to be sufficiently accurate. Divide the ship in systems containing modules so that these modules are distinguished from each other by its functionality.
Robinson, for planing chine and round bilge vessels. The prediction is valid for deep and calm water, and has the following applicability:. Van Oortmerssen, for smaller displacement vessels. With mrnnen method you can calculate the resistance of a planing holttop. Hollenbach limits of applicability.
Making a technical drawing in NX-Siemens. It is possible to adjust the hull characteristics by changing secondary parameters. This method can be used to approximate the resistance of a barge.

With this method a resistance approximation is made for the displacement condition. This tutorial aims to introduce a very simple way of doing a parametric vessel modelling at Siemens NX. The ship is modelled in a virtual environment and the idea is to be able to simulate ship performance motions, systems, propulsion in real time.
In this window all mennn parameters which are applicable for a certain method should be given. With this module resistance predictions can be made for different ship types, with nine published holtdop methods, viz: Early phase design visualizations and interactions by using the D3.
