Nauticus Early Design - a new 3D information system from DNV Software. Based on the next generation of CAD technologies, the system enables faster contract and classification design.

Nauticus Early Design will close the gap between traditional draftsmen, structural engineers and naval architects.

The new system integrates CAD and analysis, thereby enabling ship designers to perform contract and classification design faster and better. Concurrent use of one common ship product model and the powerful Brix Workflow Manager engine enables a controlled and well-managed approach to early design. The system combines state-of-the-art technologies developed by DNV Software and Intergraph Process, Power and Marine.

Nauticus Early Design offers distinct benefits to shipyards and ship designers:

• Improved quality of work through a concurrent multidiscipline environment offering the extensive re-use of data, rule-based design and support of Best Engineering Practice
• Faster contract and classification design achieved for novel designs as well as for re-designs, using the most efficient and user-friendly associative ship modeller on the market
• Seamless integration with the detail design system reduces the total shipbuilding design and production cost
• Improved workflow and support of Best Engineering Practice throughout the entire early design process, enabling all contributors and stakeholders to optimise integration of data, systems and people.

3D modelling of the design and integration with FEA and class rules

Data centric and rule-driven
A new 3D concept modeller, Molded Forms, allows for fast and accurate definition and communication of ship hull and
structure components. Decks, bulkheads, plates and stiffeners are linked together by a very robust associative data model that allows for the easy modification and update of ship models throughout the design.

The object-oriented database is multiuser and multidisciplinary, and allows project members to share data instantly
across design disciplines.

The system’s advanced rule engine enables knowledge-based engineering with a high degree of automation and the
elimination of repetitive modelling tasks. The end result is a shorter lead time and improved quality of design.

Integrated CAD and analysis
Nauticus Early Design integrates the rule check and finite element analysis programs of Nauticus Hull to validate and adjust designs interactively. Interfaces to stability programs for exchange of surface and compartment data are also a central part of the system.

Rule-based class drawings

Automatic classification and GA drawings
Nauticus Early Design automates the production of classification and key plan drawings through configurable rules
defined within the system. Class drawings can thus be generated or updated based on a minimum of data in the ship model, and the drawings always reflect the design as is and as checked against the class rules.

Main equipment can be modelled in the model for space allocation and General Arrangement drawings, weight estimates, and more. This provides a versatile application for compartmentation along with comprehensive report generation capabilities for weight, cog and material take off, making Nauticus Early Design a powerful and complete early design tool.

Improved early design work process

Nauticus Early Design closes the gap between ship designers, draftsmen, structural engineers and naval architects. It is based on next-generation CAD technologies that support the industry’s need for distributed engineering and construction.
