Feature 2 | CAD/CAM UPDATE What future for 3D design
Te future of ship design is getting more complex with advanced computer aided design (CAD) and computer aided machinery (CAM) soſtware coming on to the market. Aveva Solutions Stéphane Neuveglise, marine strategy manager explains the benefits of integrated solutions.
M
arine projects demand sophisticated design capabilities, with a plethora of data and
documents, complex schedules and vast amounts of materials and resources. To make matters worse, these resources are evolving and changing throughout the shipbuilding process as part of a dynamic workflow that demands tight coordination between internal and external parties. In order to succeed, shipyards need
highly developed solutions for generating, coordinating and managing a complex equation of information, materials allocation and resource availability, within contractually agreed schedules and costs. Tey need a business support system that fully integrates and maintains consistency between all the dimensions of the operation, and throughout the shipbuilding process. Tey need careful managed and accurate information to create savings in shipbuilding production costs and project schedules, particularly in these economically challenging times. Mr Neuveglise comments, what is the
place of design technology – 2D and 3D, CAD and CAM – within this demanding environment? He asks us to consider, 3D design soſtware, while unrivalled for the purposes of design, cannot, of itself, provide a secure environment for vendors, owners, classification societies and partners to share and collaborate on project information. It cannot provide a vehicle to dynamically interact with existing ship design, production management and design reuse. In short, while it is a design “must have”, the reality is that it can’t guarantee the right information at the right time, so that shipyards can make the right economic – as well as engineering – decisions. He states that through Aveva’s own
extensive research through it’s customers it has “painted a very convincing picture of the truly effective shipyard, in which 3D design information sits right at the heart of the operation, but only on condition that it is integrated into the wider information management picture.” Aveva’s soſtware solution looks at the design process as a whole and is broken
down into several separate parts such as the executive management, business and capture of sales, planning and control, engineering and design, procurement and supply chain, stock and logistics, production, customising and delivery; and the extended shipyard.
The reality of the shipyard Most of the planning and execution of the shipbuilding process is highly dependant on the design of the vessel. While the design and management teams are tasked with engineering all aspects of the ship, they are also responsible for ensuring the relevant engineering; material and production information is optimised and available to support the manufacturing, assembly and commissioning processes. Te engineering team must be able to make full reuse of past designs, and rapidly create and validate new designs to maximise the efficiency of the vessel and its production and many other discipline-specific applications in use across the project. Yet in reality most shipyards employ
a wide range of 2D and 3D design applications, from a host of different soſtware suppliers, that provide little or no operational integration, explains Mr Neuveglise. Te result of this is a collection of isolated databases that actually lock away the critical design information, making it difficult to share and coordinate. These ‘silos’ of information also demand a great deal of manual intervention to manage, and, therefore, negatively impacting on project productivity. He adds: “It’s design technology gone seriously wrong”.
Production: the most complex phase of the project, with the smallest margin for error. Changes and rework resulting from poor upstream coordination can have a massive impact on project schedules.
