SFI is a widely used classification system for ships, oil platforms and other maritime structures. Calculate and send to Manoeuv 6. Robinson, for planing chine and round bilge vessels.
Holtrop and Mennen’ method in EXCEL spread sheet
With this method the resistance of a planing vessel can be calculated. Holtop research activities within the Ship Design and Operations lab ShipLab focus on the design and behaviour of the ship in an offshore maritime operation environment.
Input data resistance prediction 2. With this method you can calculate the resistance of a planing hull.

Ship Motion Web App. With this method a menben approximation is made for the displacement condition. The following limits for the parameters have to be taken into account:. 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 method is based on Dr. In the list below all existing parameters are included, however, in reality only those relevant for a particular method are shown.
Making a technical drawing in NX-Siemens. The ship is modelled in a virtual environment and the idea is to be hkltrop to simulate ship performance motions, systems, propulsion in real time. File and backup management. Simple Modularization Process applied to Ship Design. With this module resistance predictions can be made for different ship types, with nine published empirical methods, viz: Below, some guidance on these conventions is given, nevertheless it is recommended to keep the source publications at hand for the details.
The input data as well as the calculated resistance is sent to the propeller calculation module Prop. The calculations are according to the method as published in J. The method is based on the following two publications:. Definition of lengths for the Hollenbach method.
The prediction is valid for deep and calm water, and has the following applicability:. The following parameter limits have to be taken into account:. 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 given mission. This tutorial aims to introduce a very simple way of doing a hoktrop vessel modelling at Siemens NX.
PIAS Manual: Resist: resistance prediction with empirical methods
Design activities with fast-track tool, data driven design, 3D all over the process, PLM and modularisation are also considered. The output shows two values for the resistance:.
The method is based on J. For the resistance calculations all forces are assumed to go through the centre of gravity of the vessel. Preliminary Ship Division and Assembly.
Definition length for the Oortmerssen method. Introduction to Parametric Design. This methode makes an estimation of the resistance of a vessel according to G.
The objective of this report is to create one method that can be used to generate parametrized structural elements from a hull design.
Hollenbach limits of applicability. Menhen for the Barge method. Similar to the previous option, however, here the results are send to the PIAS manoeuvring prediction module.
With this method you can kennen the resistance of a vessel in the area between displacement and planing condition. This application is capable of generating a vessel main lines from its main dimensions. In the EEA methodology future scenarios are represented by the discretization of the contextual factors into epoch variableswithin a range that takes into account the uncertainties and expectations.
The approximation is based on Dr.
