The right shipbuilding CAD/CAM System

FORAN Electrical Design provides advanced functions to manage all the relevant aspects of the design and production of electrical systems on ships.

Fully integrated with the Outfitting entities, allows the completion with electric specific data of the equipment and fittings, both pipe and HVAC, along with the definition of the electrical fittings themselves.

From the electrical balance of the ship in the different operation conditions, to the latest connection sheet for the wiring of each cable core, FORAN covers it all, with special stress in the cable management, a key chapter in the total cost of the ship.

There is a specific solution for the edition of single wire diagrams, where equipment, fittings and the cables that connect them are referred from their master lists, with all the data they can store. Any change is therefore automatically propagated to the 3D and the rest of the diagrams involved, keeping the data consistency.

The cables edition includes the calculation of the minimum section, the complete wiring information, the automatic routing through the network area, the generation of the signals list, the nesting in reels and many other functionalities.

Besides, the cable trays include complete manufacturing data, cable pattern rules, full transits information, cable tray supports and anything related with the accurate modeling.

Electrical Standard Libraries

The definition of the electrical standards and elements includes basic data tables (cable segregations, nominal cross-sections, tray standard sizes, cable materials, etc.), cable catalogues and cable nominal sizes. Available data includes cable composition, core size, overall diameter and other mechanical and electrical characteristics associated to each nominal cross section, classes and components of electrical equipment, fittings and instruments, cable segregations and cable routing rules.

Electrical Diagrams

FSYSD

All cables and electrical equipment pieces placed on the diagram are automatically registered in the FORAN database and are ready to be reused in the rest of the applications. On-line, block, wiring and lighting diagrams are some examples of the types of documents that can be created.

Key features:

• Information integrity

• Automatic calculation of the cable size

• On-line edition of all data of the elements in the diagram

• Specific functions to handle equipment and fitting symbols

• Automatic and configurable labelling of all the elements in the diagram

• Automatic generation of configurable graphic lists

• Integration of pipe fittings with electrical connection

Cable Routing

FCABLE

The cable routing is based on routing paths, or sequences of 3D points (nodes) connected by straight segments. Routing conditions controlling the segregations and filling rules are assigned to every segment of the path.

Nodes representing penetrations can be assigned to rules for controlling the cable population in the penetration: penetration fitting, allowed area or number and type of watertight blocks.

Cables can be routed either in automatic, semiautomatic or manual modes. The automatic mode evaluates the shortest path that fulfils the routing conditions and the existing filling rules. The semiautomatic mode allows marking some points as mandatory or forbidden. Once a cable is routed, its weight, length, center of gravity and the cable tray population are automatically updated.

Cable Tray Modelling

Cable trays may be modelled automatically according to the cable tray pattern assigned to each segment or polygonal of the nodal network. Functions for inserting manually standard fittings are also available. Cable penetrations or transits are automatically modelled based on the information given to the penetration nodes. The on-line clash checking can be used to avoid mounting errors.

The user can generate different types of drawings, including automatic cable route pull sheets and cable trays isometric sketches. FORAN controls the consistency of the process and creates automatic connection sketches.

I/O Signals

To define I/O signals, in addition to each signal proper values, such as the type of signal (analogue, digital or serial line), the I/O card type, the range of measurements, alarm data, etc, to assign a process station and an instrument (field element) to the signal, and choose the corresponding cable wires used for each signal to propagate. Several kinds of I/O lists can be extracted.
