Various Modules

Stability and Hydrostatics
The stability and hydrostatics analysis modules are used in the intact and damaged conditions to assess the stability of designs against UK, US and Australian Military as well as UK and International Mercantile Standards. This module has been validated by the UK MoD Naval Authority for Ship Stability and is a core analysis capability within Paramarine and its on-board variants, Seagoing Paramarine and Paramarine SeaWeigh. The sophisticated 3D solid modelling techniques utilised by Paramarine provide the high accuracy required for assessing submarine stability, where complex geometries are often involved.

Powering and Endurance
The Powering and Endurance modules utilise a number of in-built powering series to provide highly accurate powering predictions for a given design. When combined with a mission profile, propulsion system components and energy provision, the endurance for a given design can be determined. This allows the design team to optimise their concepts to maximise endurance, minimise fuel consumption and emissions or trade off different propulsion system options.

Structural Analysis
The extensively validated structural analysis modules utilise capability developed by QinetiQ's Maritime Practice. This capability allows the assessment of the structural capability of ships and submarines in both the intact and damaged conditions. Naval Architects and Design Authorities can assess and optimise longitudinal strength, critical sections, bulkhead collapse, crack growth and residual strength as the design evolves against UK Standards. The allied structural desktop toolkit provides a rapid approach for the definition of plate and scantlings using UK and other classification society rules.

Early Stage Design
The Early Stage Design module is based upon the Functional Building Block Approach developed by UCL.

This module allows the designer to build the concept based upon the various functional requirements placed upon the ship or submarine. The designer is able to specify requirements for weight, volume, power, manning, payload and so on to assess the supply provided within their design. The automatic auditing capability provides the designer with the ability to continually assess the balance of the design and to perform trade-off's for different configurations.

Above Water Vulnerability
This module provides the designer with the ability to assess the vulnerability of a given concept to attack. The user can assess, for a given configuration and threat, the effects of a blast on the integrity of its various systems.

Radar Cross Section Analysis
This module allows a non-expert designer to rapidly identify and correct any design features that result in undesirable radar cross section signature. This is achieved through the provision of polar plots as well as a visual representation via bitmaps or movies which highlight areas of high return for any elevation or polar position.

Advanced Hull Form Generation
Our advanced hull form generation capability utilises state-of-the-art XT Technology, where high quality surfaces can be created from a minimum of bounding and internal curves. A number of sophisticated mathematical techniques are available to provide the basis for the user to create industry standard NURBS surfaces. These are used to develop hull forms, superstructure and appendages. Paramarine provides a wide range of curvature analysis and diagnostic tools to allow the design team to refine their hull forms to their required standards.

Design for Production
This module allows the development of a cost of production for the design based upon the engineering work necessary to build the design, by combining the cost of labour and materials involved in the construction. It allows the design team to assess the merits of different production strategies, as well as trading off different system options. This unique capability provides an alternative to established weight based costing techniques which are dependent on historical data that may not be applicable to today's innovative design and construction techniques.

Manoeuvring
Paramarine provides manoeuvring analysis for ships and submarines. The surface ship module can assess monohull and trimaran manoeuvring for standard and user defined manoeuvres and can also include autopilot inputs. The submarine module is a coefficient based approach for the analysis of underwater manoeuvres.

The FORAN interface
This provides a two-way data transfer capability between Paramarine and Sener’s ship production system, FORAN. The advanced transfer involves Paramarine providing the vessel’s external envelope and internal spatial arrangement (through the subdivided hull) to Sener's FORAN system for production detailing.
