Definition of lengths for the Hollenbach method. Ship Motion Web App. Hard chine regression data boundary. Activities have strong connection with the industry, via the Blue Maritime Cluster partners.

The objective of this work is to present a simplified modularization process appllied to Ship Design. For the resistance calculations all forces are assumed to go through the mennwn of gravity of the vessel.

Heave, pitch, vertical motion and vertical acceleration responses are calculated as function of length, breadth,draught, block coefficient, waterline breadth and operational profile. Hard bilge regression data boundary.

Local cloud monitor 7. This work focuses on data-driven documents D3 examples applied to the conceptual ship design process, especially in how to effectively and quickly filter and present complex input, multilevel and multiclient interactions, associating into design knowledge. For the parameters as given at the first menu option, here holttrop resistance approximation is made, and the results are printed in a table.

This methode makes an estimation of the resistance of a vessel according to G.

Ship Lab – Ship Design and Operation Lab – NTNU in Ålesund

The following limits for the parameters have to be taken into account:. Early phase design visualizations and interactions by using the D3. An open-source application capable to run real-time ship motion simulations in a web browser, in any device of any operational system with HTML5 compatibility.


The output shows two values for the resistance:. Van Oortmerssen, for smaller displacement vessels. A web based parametric ship design. The input data as well hlltrop the calculated resistance is sent to the propeller calculation module Prop.

The definition of all parameters is strictly according to the convention of the applied resistance prediction method, which does not have to agree with the PIAS convention. Diagram of resistance components 4.

Hollenbach, for displacement vessels. Calculate and send to Manoeuv 6. File and backup management. With this method the resistance of a planing vessel can be calculated. Definitions for the Barge method. Mennwn is a widely used classification system for ships, oil platforms and other maritime structures. The following parameter limits have to be taken into account:. They can be changed by clicking and dragging the sliders.

Holtrop and Mennen’ method in EXCEL spread sheet

For calculations in the preliminary design stage this is assumed to be sufficiently accurate. Input data resistance prediction 2. The focus has largely been structural components, economic aspects, and especially hierarchical breakdowns. In the list below all existing parameters are included, however, in reality only those relevant for mebnen particular method are shown.

Introduction to Parametric Design. The prediction is valid for deep and calm water, and has the following applicability:.

PIAS Manual: Resist: resistance prediction with empirical methods

Graphical representation of closed-form functions for heave, roll and pitch accelerations. 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. Design activities with fast-track tool, data driven design, 3D all over the process, PLM and modularisation are also mehnen. Savitsky, for planing chine vessels.


It is possible to adjust the hull characteristics by changing secondary parameters. 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. Below, some guidance on these conventions is given, nevertheless it is recommended to keep the source publications at hand for the details. The objective of this report is to create one mejnen that can be used to generate parametrized structural elements from a hull design.

App to calculate the total resistance of a displacement ship based on the Holtrop and Mennen method. Calculate and send to Prop 5.

Simple Modularization Process applied to Ship Design. In this window all ship’s parameters which are applicable for a certain method should be given.

Holtrop calculation

Graphical representation of estimated motion responses for ships. The approximation is based on Dr. Making a technical drawing in NX-Siemens. With this method you can calculate the resistance of a planing hull.

With this option design version can be managed, with a mechanism as described in Data storage and backups. 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. The method is based on the following two publications:. Robinson, for planing chine and round bilge vessels.

With this method you can calculate the resistance of a vessel in the area between displacement and planing condition.
