3D Modelling

After the concept development and completion of the main engineering calculations, the 3D modelling stage begins. At this stage, all design solutions are translated into a unified digital model, where hull structures, outfitting, ship systems, equipment, piping, ventilation, cable routing, electrical systems, and automation elements are developed in an integrated environment.

We perform 3D modelling using FORAN software. This platform enables integrated ship design within a single digital environment, where all major engineering disciplines are developed in coordination. This is particularly important in shipbuilding, as modifications to one system may affect hull structures, equipment layout, service zones, weight distribution, installation processes, and operational performance.

The process begins with the development of the hull model. The basic hull geometry is created, including main reference planes, frames, decks, bulkheads, shell plating, and bottom, side, and deck structural elements. The hull model forms the basis for all subsequent design work. At this stage, it is essential to ensure geometric accuracy, structural consistency, and compliance with previously established design and calculation results.

Once the hull model is established, parallel development proceeds across multiple disciplines. Outfitting, ship systems, piping, equipment layout, ventilation, cable routing, electrical systems, and automation are all developed concurrently. This approach enables early multidisciplinary coordination, prior to the release of workshop documentation and commencement of production.

Outfitting design includes the arrangement of spaces and structural elements, such as doors, hatches, ladders, platforms, gratings, equipment foundations, insulation, lining, and other components required for vessel operation. At this stage, passageways, accessibility to equipment, maintenance zones, installation feasibility, and compliance with the general arrangement are carefully verified.

Ship systems are developed in parallel within the 3D model. Piping routes are designed, including valves, pumps, filters, heat exchangers, tanks, expansion joints, penetrations through bulkheads and decks, supports, and other system components. This allows engineers to define optimal routing and verify compatibility with hull structures, equipment layout, cable routes, and outfitting elements. System design also considers equipment dimensions, maintenance access, installation and removal requirements, positioning of valves and instrumentation, flange connections, supports, and penetrations. This ensures not only proper system layout but also operational efficiency, maintainability, and constructability.

Electrical systems are designed as a separate discipline within the model. Electrical cabinets, switchboards, control panels, cable trays, cable ladders, penetrations through decks and bulkheads, automation equipment, sensors, and actuators are all integrated into the 3D environment. Electrical design is coordinated with hull structures, piping systems, ventilation, outfitting, and service access requirements.

One of the key advantages of 3D modelling is the ability to identify clashes, interference zones, and technical constraints at an early stage. This is especially critical in machinery spaces, pump rooms, steering compartments, technical spaces, and other densely packed areas where multiple systems and components are installed simultaneously.

Based on the 3D model, data is generated for the development of design and production documentation. The model provides the basis for drawings, schematics, material take-offs, equipment lists, piping routes, cable routing data, penetrations, foundations, and other engineering deliverables.

The 3D model ensures continuous data consistency throughout the project lifecycle. Any design changes can be evaluated for their impact on related systems, allowing timely adjustments and preventing inconsistencies between hull structures, systems, equipment, electrical components, and documentation.

The outcome of this stage is a fully coordinated digital vessel model, incorporating hull structures, outfitting, ship systems, equipment, piping, ventilation, cable routing, and electrical systems. This model serves as the basis for production documentation, specification development, manufacturing preparation, and further construction support.
