CAD/CAM UPDATE Consider a large vessel, such as a
350metre long oil tanker which has a cable that needs to run down the length of the deck and deliver a defined voltage. E³.cable will calculate the most efficient route for this cable while achieving electromagnetic compatibility. The type of cable used in different environments and situations can also be simply managed within E³.cable. In an engine bay for example, cables that can withstand higher temperatures are essential. When choosing a cable within E³, the user can specify the name, diameter and gauge, or pick from a predefined drop down list of industry-standard cables. There are day to day efficiency and productivity gains to be had when using E³ or any CAD solution for that matter, but one of the most significant benefits not yet covered is the ability to deal with the changing technology and client requirements at any stage within the development and build process. The introduction of a new satellite navigation
system two years into the design of a large complex vessel would normally result in extensive rework of the electrical cable design, but with E³.cable it is as simple as updating a single sheet; other areas within the electrical system will automatically be modified to reflect the changes. For efficient panel design, Zuken offers
E³.panel for the placement and wiring of devices in panels and on mounting plates. E³.panel is fully integrated with all the other E³.series design and documentation tools as

standard. This environment enables the naval engineer or system architects to integrate all the physical panel data, and then go on to design the layout and associated wiring.
Matching Manufacturing It is not just about quick and efficient design. Naval engineers want to work with a tool that is easy to use and can reliably supply accurate
purchasing and manufacturing data. E³.cable and E³.panel’s ability to deliver the essential details in a format that can easily be interpreted by manufacturing engineers takes this tool suite to the next level, according to its developers. For example, engineers can automatically calculate wire and cable lengths and attributes, details about cable duct requirements, as well as placement.
