FINITE ELEMENT ANALYSIS OF A SHIP SEGMENT UNDER WINCH LOAD 

DeNaval Macho1

 

as2con`s engineers completed a new analysis of a ship segment under winch load, conducted using finite element method on a model constructed in CAFE software.

Analysis has been conducted for a Norwegian client, in collaboration with De-Naval d.o.o., with a goal to obtain the response of the deck and surrounding structure.

As a part of a successful, on-going cooperation with De-Naval ltd., a naval architecture design office from Rijeka, Croatia, as2con`s team has been involved in a new series of analyses condusted on a model crated in CAFE software. The latest project included a lifting analysis of a 35 m LNG-powered tug boat, analyzed using the Finite Element Method. For the purpose of the analysis, parts of the ship structure have been subjected to design loads and placed on corresponding positions.

CAFE TEAM AT THE 13th COMPIT CONFERENCE

COMPIT logo 2        

  

CAFE team members Svemir Bralić (BVB, Croatia) and Vassilios Zagkas (SimFWD P.C, Greece) presented the CAFE software and its features and capabilities at the 13th International Conference on Computer Applications and Information Technology in the Maritime Industries (COMPIT) that took place in Redworth, UK, from 12th to 14th of May 2014. 

 

The paper “Real time collaborative design of ship and offshore structures using BVB CAFE” presented CAFE as a unique platform developed for collaborative design of complex ships and offshore structures that enables two or more parties involved in structure lifecycle to work simultaneously during the whole process (i.e. ship-owner, fleet managers, designer, class society, shipyard etc. with one or more of its representatives). This paper presents the lifecycle capabilities of the software through a step by step collaborative design of an Ice Class Tanker using the enhanced and simplified man-model interaction, and it is available here.

CAFE SOFTWARE AT ICCAS 2013

icass     

The use of CAFE software in ship design will be one of the topics at this year`s International Conference on Computer Applications in Shipbuilding (ICCAS)  that will take place in, Busan, South Korea from 24th to  26th of  September 2013. 

 

The paper „Rapid development of Ro-Pax concept by introducing an early stage FE analysis in CAFE innovative ship design environment“, created by Vassilios  Zagkas (Naval Architecture Progress), Alan Klanac and Darko Frank (as2con-alveus) as well as Svemir Bralić (Brze Vise Bolje) was accepted as one of the 80  papers to   be presented to experts in the field and potential future CAFE users.

 

The 16th ICCAS will review operational experience from existing computer applications in the design and build of ships and offshore structures and will cover a full range of topics including; CAD, CAM, integrated systems, knowledge management, simulation and virtual reality applications, etc. It will also examine the advances in Information Technology which have contributed to increased productivity in both shipbuilding and maritime operations.

ANALYSIS OF A BRITISH NAVY SHIP USING CAFE

cammel     

Using finite element analysis in CAFE software, as2con conducted the assessment of the response of a ship structure incase of emergency towing. The analysis was conducted for a British navy ship and represents an exciting project that will hopefully result in many new successful collaborations. The project is a result of a cooperation between as2con and the British Cammell LairdShiprepairers & Shipbuilders Ltd.

 

CAFE AT THE UNIVERSITY OF RIJEKA

uniri

In the past three years, students of Faculty of Engineering at the University of Rijeka, have been given a chance to gain new knowledge and experience through usage of the CAFE software in their academic work. Students have used the software for their projects related to ship structural design and analysis. CAFE’s capabilities to rapidly generate ship hull model, and prepare it for Finite Element Analysis have greatly enhanced the learning process.

 

COLLABORATION WITH VIKTOR LENAC SHIPYARD ON A REFIT OF A HEAVY LIFTING PIPE LAYING SHIP

Sampson_1  

Starting from May 2012 , serious of analyses, using the CAFE software, were conducted by as2con, for a special heavy-lifting pipe-laying ship (1600 t) that has undergone a refit process. as2con performed hull global strength analysis including analysis of collapse, pipe rack and other structural details.Since the beginning of 2012, as2con has been actively involved in a series of projects with this Croatian shipyard. These include a number of tasks related to engineering analysis and design, as well as the composite repairs using COMPA technology.

COLLABORATION WITH NAVIS CONCEPT

Navis

In a new project that begun this spring, FEM analysis of the hull structure of an open top river and sea-going barge was conducted using CAFE software. The analysis focused on the hull girder strength due to the vertical bending and torsional moments and was also conducted as a result of a collaboration with Navis Concept, a naval architecture consultancy from Rijeka, Croatia.

3D VISUALISATION AND MASS CALCULATION OF SHIP EQUIPMENT IN CAFE

CAFE Import equipment small

We are happy to inform all ship equipment producers of a possibility to import data of different equipment and visualise the equipment in ship design software CAFE: Such an option helps customers to promptly get insights into the suitability of equipment dimensions with the particular ship space, as well as to simply and immediately calculate ship total mass.

We believe that by enabling this, we provide a prime service to CAFE users, while giving the producers a competitive advantage. Find more about how to import your equipment’s data here.

LONGITUDINAL STRENGHT ANALYSIS FOR A RIVER TANKER

Bomex

We have performed a longitudinal strength analy-sis of the 110 m river tanker Neptunus using the finite element method (FEM). The ship has been modelled using CAFE ship design software. The task has been performed for the BOMEX 4M, shipyard from Serbia.

 

CONCEPT DEVELOPMENT OF AN ASPHALT CARRIER

3._maj_nacrt

In collaboration with 3. MAJ shipyard, as2con has worked on development of a large asphalt carrier. Usage of CAFE ship design software is essential in this project, due to its capacity for rapid generation of hull structural concepts. The project results will be publicly presented in the coming SORTA conference, in October 2012.

CAFE TEAM READY FOR THE INTERNATIONAL MARINE DESIGN CONFERENCE

Offshore_jacket_example

CAFE team members Darko Frank, Svemir Bralić and Alan Klanac and Igor Juričić, from Intergraph, brought new discoveries of their research in a paper called “CAFEmesher: An Advanced Complex FE Mesh Generation Algorithm Utilized in SmartMarine® 3D Environment”.The before mentioned paper will be presented at the International Marine Design Conference in June 2012. in Glasgow, UK.This paper outlines the importance of providing a designer with accurate strength assessments in an early stage of the design process and also proposes the solution for bridging the gap between CAD and FEM software tools to overcome the repeated modeling for FEM purposes.The solution integrates SmartMarine 3D with CAFE system and enables SmartMarine3D to exploit CAFE’s mesh generation capabilities.The PDF version of the abstract can be downloaded here.
