Naval Architecture & Engineering Analysis
• As a integrated ship design tool, Paramarine provides a complete solution for:
− Geometric Modelling and hull generation
− Stability and hydrostatics
− Structures
− Sea-keeping
− Manoeuvring
− Military Analysis
• These modules provide a foundation upon which the Early Stage Design Tools are based

Why Paramarine®?• Paramarine is the worlds only integrated naval architecture design and
analysis product for ships and submarines.
• Paramarine is extensively validated by third parties – users have high confidence in the output.
• Paramarine draws together sophisticated visual based design and engineering analysis.
• Paramarine compresses the early stages of the design process reducing risk and cost and improves understanding of the design in the early stages.
• Fully auditable parametric designs linked to requirements allow trade off studies to be performed within a single environment.

Paramarine® Integrated Naval Architecture
• In Paramarine, definition data and analysis functions are modelled using objects which can be connected together to represent aspects of the design.
• Change propagates through the design with minimal user interaction
• Data items capture all relevant definition commands providing configuration control.
• Object relationships provide powerful tools for modelling the design problem allowing techniques such as Optimisation to be effectively incorporated into the design process

Paramarine Early Stage Design Modules
Paramarine features a unique ship/submarine design module which allows the designer to represent both requirements and solutions using conceptual information. Designs can be quickly reconfigured to explore new solutions with minimal design definition overhead.
The tools allow the user to:
• Define their own parametric rules
• Coarsely represent geometry and vessel characteristics
• Automatically evaluate design balance (i.e. Hydrostatics, Stability and Requirements)
• Concept Design can combined with Structural Definition to generate a parametric Product Model and used to produce early cost estimates of work and materials

Design for Production
• Generates a production database based on Concept, Systems and Structural design
• User defines Production Block subdivision strategy
• Then uses simple production rules governing plate, stiffener andservice line (cables, pipe) stock sizes
• Production Feasibility (cranage/dimensions)
• Quantity of Materials
• Identifies joins etc “Work” creating cost drivers

Design Space Exploration
• On behalf of the UK MOD, GRC has developed a unique capability to explore the design space for new requirements
and concepts
• GRC have considered 5000 design
variants on a single run under an existing contract but more possible!
• All designs assessed through Paramarine – invalid designs are discarded
automatically by Mode Frontier
• Successful designs are evolved further
against criteria
eg minimise cost / maximise endurance

External Links and Interfaces
GRC is focussed on ensuring that the benefits of the integrated nature of Paramarine can be extended beyond the product:
GRC has created interfaces for:
• FREDYN for dynamic stability
• FORAN Production Design System from SENER ES
• ABAQUS/CAE for FEA from 3DS SIMULIA
• Altair HYPERMESH for FEA
• GAMBIT for CFD via parasolid files
Create whole ship FEA models in a day – not weeks – using pre-existing structural definition from PARAMARINE with all material properties, stiffener definitions and sections translated into ABAQUS or HYPERWORKS
