Introduction
Paramarine is a fully integrated Naval Architecture tool, where all design and
analysis work takes place within one common graphical user interface,
eliminating the need for data exports to other packages.

Parametric Design Approach
Paramarines object orientated design approach allows designs to be generated
and controlled with ease through input characteristics. These can be used to
parametrically define the hull, which can be assessed for stability, structure and
manoeuvring performance. The resulting values are always up to date,
eliminating the need for the user to manually recalculate any part of the design.
Paramarine is an Object Oriented design system for the marine sector. It consists
of a kernel database (the Kernel) driven by a Graphical User Interface (GUI)
mostly by text commands in Kernel Command Language (KCL). The GUI queries
the Kernel in various ways in order to provide output to the user. A Paramarine
design is held in a hierarchical design "tree" structure of "placeholders" (folders)
and functional objects that apply to specific types of data (i.e. geometry,
stability, analysis data).
In a manner similar to spreadsheets, objects within Paramarine can be interlinked (that is, "wired") to build up a result. The only constraints on "wiring" are
that a circular reference must not be formed, and that the data is of a compatible
data type (i.e. number, geometry element and so on). This facility allows the
designer to construct many types of model ranging from concept sizing
parametric models to complex stability analyses that will automatically recalculate when constituent items change.

Surface Modeller & Solid Modeller
The surface modeller enables the designer to develop a surface-based
geometrical definition of their ship or submarine. This license configuration
includes functionality to support simple geometrical types such as Non Uniform
Rational B-spline Surface (NURBS) entities, planes, polylines, and more complex
surface fitting.
To create a surface from sectional data there are three different methods: lofting,
blending and fitting.
Structures
The structural definition in Paramarine allows the swift definition of scantlings for
an entire ship or submarine. Given a subdivided hull, Paramarine generates the
geometry of all the panels and bulkheads for the vessel. The panels can then be
assigned a scantling definition consisting of plating and stiffener schemas.
Stability Analysis Core Module
This module is normally used in conjunction with one or more of the three
advanced stability modules, which provide more specific stability calculations
and GZ criteria for warships, commercial ships and submarines. The functionality
includes the following:
Loading conditions (surfaced and submerged) including normal or
compensated tanks
GZ curves: intact, damaged or balanced on a wave
Cross-flooding time based simulation and analysis against criteria
Damage definition
Floodable length calculations
Freeboard calculations
One and two point grounding analysis and assessing float off
Limiting KG curves for stability management
Deadweight moment curves for operational use
Tank calibrations
Define the watertight subdivision
Docking analysis
Launching calculations
Powering & Endurance
The Powering Analysis capability of Paramarine enables the designer to assess
the effective power of their vessel including air resistance, appendages, fouling,
propellers, roughness, shallow water, amongst others using a variety of
regression data.
The Endurance functionality within the Powering module allows endurance of a
vessel to be analysed by specifying the operational profile, for either surface or
subsurface vessels.
Hull Generator
This powerful module allows users to quickly create hull forms or any geometric
shape within the Paramarine software suite. Hull Generator provides the
capability to rapidly define complex surfaces using a minimal number of curves.
From these surfaces solid bodies can be formed.
Design for Production
GRC has enhanced the functionality of Early Stage Design. This allows modern
Design for Production (DfP) techniques to be applied at the initial design stage,
enabling evaluation of DfP issues right from the outset. For complex vessels such
as warships, submarines and offshore support vessels, it is essential to consider
production aspects of systems and outfit, including their routings, from the
earliest stages of design in order to reduce the work content associated with
production aspects of the vessels systems. DfP has been implemented in
Paramarine by linking the functional design with production processes to
generate feasibility and costing data associated with a particular build strategy.
Design Space Exploration
To handle the large number of designs generated by the design space
exploration, an automated process was developed. The automated process was
split into two components, the design process, and the exploration process.
modeFRONTIER is a multi-objective optimization and design environment, written
to allow easy coupling to almost any computer aided engineering (CAE) tool,
whether commercial or in-house.
