Success Story

LiftShip

LiftShip

Customer challenge

Shipyards need to lift and manipulate very large steel structures during construction. The complexity of the structure and lifting mechanisms present risks to the shipyards in time, money, and safety. To mitigate the risks, shipyards analyze lift scenarios through Finite Element Analysis (FEA). FEA of models are constructed to address a specific lift scenario and require trained specialists to create the Finite Element Model (FEM) whereas 3D detailed AutoCAD models are available for reuse.

Project goals

The aim of this project was to utilize the existing production design model created in AutoCAD and ShipConstructor to create an FEM and associated lifting configuration data in order to rapidly create an FEA for verification of the soundness of a lifting and handling operation. The desired outcome was to integrate this capability into the existing software solutions, minimize the disruption to normal production workflows of designers while enhancing the capabilities and exportability of data.

Solution

The team leveraged AutoCAD Mechanical to enhance the capabilities in the ShipConstructor design model and drawing outputs. Through the functionality of AutoCAD Mechanical, the team was able to leverage the ISO 10303 STEP protocols for export of geometric structural components into a neutral data format that could be leveraged by multiple downstream tools. This allowed Altair Engineering the ability to easily read and create the FEM for their Hyperworks FEM visualization and analysis suite.

Business outcome

FEM creation for large-scale ship structures could take as long as 400 hours to complete with the same level of detail that would be available from a production design model. By re-utilizing the existing design model for direct FEM generation, customers are able to realize almost two orders of magnitude savings. Automatic FEM creation through the project results are just a few hours vs. hundreds of hours previously, whereas more lift models and analysis can be performed in the same timeframe.

Conclusion

This project was contracted by Advanced Technology International that was sponsored and funded by NAVSEA and the National Shipbuilding Research Program (NSRP) in effort to integrate these systems to help improve the overall processes in the ship design and shipbuilding & repair industry. The collaboration within the project team assembled allowed for the project results to be realized for those companies that currently have Autodesk and SSI Products in use within their respective organization.

ShipScan

Engineering and design firms, including shipyards, require an accurate and efficient method to survey components, areas and systems to document current as-is conditions. This effort is commonly known as Shipchecking; where several people survey compartments, areas, components, and systems of ships and they physically measure, develop sketches, and take many photographs. A very labor intensive process that is susceptible to errors in capturing as-is conditions is required to update 3D CAD Models.

ExpressMarine3D to ShipConstructor

Shipyards and Design Agents that employee both Naval Architects and Marine Engineers have always used some rapid modeling naval architect software in effort to get a quick 3D model of a ship hull structure as an initial design. However, typically these early-stage 3D design models are not easily transferable into a detailed 3D production model that can be utilized to manufacture detailed structural components of a ship.This project found a way to pass a rich early phase structure-model to a detail-engineering production tool without losing properties and metadata from an early-stage design tool (ExpressMarine3D) into a detail production design models tool (ShipConstructor and its Marine Information Model - MIM, which is built on top of AutoCAD, and also utilizes Navisworks).In a shipbuilding detail design environment, dedicated tools focus on handling the level of accuracy, versatility and model completeness necessary to produce high quality production support information.   Prior to the shipbuilding detailed engineering, tools for early and basic design must be adapted to handle the rapid changes that are characteristic of the early design phase.
