SFI is a widely used classification system for ships, oil platforms and other maritime structures. Design activities with fast-track tool, data driven design, 3D all over the process, PLM and modularisation are also considered.
Ship Lab – Ship Design and Operation Lab – NTNU in Ålesund
Holtrpo 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. Divide the ship in systems containing modules so that these modules are distinguished from each other by its functionality. Simple Modularization Process applied to Ship Design. The approximation is based on Dr. 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.
Activities have strong connection with the industry, via the Blue Maritime Cluster partners. For the parameters as given at the first menu option, here the resistance approximation is made, and the results are printed in a table.
Definition length for the Oortmerssen method. 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. Early phase design visualizations and interactions by using the D3. Hard chine regression data boundary.
Savitsky, for planing chine vessels. Making a technical drawing in NX-Siemens. 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. With this option design version can be managed, with a mechanism as described in Data storage and backups. 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.
This tutorial aims to introduce a very simple way of doing a parametric vessel modelling at Siemens NX. Below, some guidance on these conventions is given, nevertheless it is recommended to keep the source publications at hand for the details. Hollenbach limits of applicability. Robinson, for planing chine and round bilge vessels. File and backup management.
Local cloud monitor 7. Ship Motion Web App. Heave, pitch, vertical motion and vertical acceleration responses are calculated as function of length, breadth,draught, block coefficient, waterline breadth and operational profile.
For the resistance calculations all forces are assumed to go through the centre of gravity of the vessel.
Graphical representation of estimated motion responses for ships. Introduction to Parametric Design. Diagram of resistance components 4. The parameters should be within the following limits:.
The prediction is valid for deep and calm water, and has the following applicability:. With this method you can calculate the resistance of a vessel in the area between displacement and planing condition. 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.
With this method a resistance approximation is made for the displacement condition. Ho,trop and send to Prop 5. App to calculate the total resistance of a displacement ship based on the Holtrop and Mennen method.
Holtrop and Mennen’ method in EXCEL spread sheet
Calculate and send to Manoeuv. For calculations in the preliminary design stage this is assumed to be sufficiently accurate. The focus has largely been structural components, economic aspects, and especially hierarchical breakdowns. Joltrop following parameter mebnen have to be taken into account:. The method is based on J. In the list below all existing parameters are included, however, in reality only those relevant for a particular method mennne shown.
With this module resistance predictions can be made for different ship types, with nine published empirical methods, viz: Van Oortmerssen, for smaller displacement vessels. Hard bilge regression data boundary. 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.
Definitions for the Barge method.
holtro They can be changed by clicking and dragging the sliders. The method has the following area of applicability:. It is possible to adjust the hull characteristics by changing secondary parameters. Hollenbach, for displacement vessels.
