GRC Ltd, a wholly owned subsidiary of QinetiQ Limited, has launched a new and improved version of its ‘Paramarine’ ship design software and ‘Seagoing Paramarine’ software, which is used for onboard ship stability and structural assessment. Enhancements to both software packages include a number of exciting new modules that will be a great asset to ship designers and ship operators.
One of the most significant new modules in Paramarine is Design for Production. Used in conjunction with the Concept and Structural Definition models it can generate a product model of every single item required for ship construction - from individual plates to weld junctions. It also identifies specific construction issues such as whether or not dockyard facilities have the capacity to meet a ship’s build requirements. One of its most useful features is the creation of a detailed cost assessment. Because this is based upon the physical ship model, changes are automatically accounted for allowing alternative design arrangements to be investigated in detail. The Design for Production module is currently being evaluated on the MARS (Military Afloat Reach and Sustainability Programme) ship concepts by the MOD Price Forecasting Group.
One of Seagoing’s main enhancements is currently being evaluated at sea on board HMS Monmouth. After the grounding of HMS Nottingham in 2002, a range of damaged ship structural analyses were jointly developed by the UK MOD's Sea Systems Group, QinetiQ and BMT Defence Services. These have been seamlessly integrated into Seagoing and in support of this the Paramarine structural definition and analysis modules have been greatly enhanced to allow the creation of more detailed and accurate ship structural models.
This new version of Paramarine also includes the long awaited sea keeping analyses. Two sea keeping codes have been integrated into Paramarine: PAT-2000, developed by GRC, QinetiQ and Southampton University/HydroTech and ProteusF from Strathclyde University/Safety at Sea Ltd.
In addition to it being a more user friendly and productive system, other enhancements to Paramarine include:
- An increase of up to 300% in computational speed.
- An upgrade to the Powering module with new high speed resistance prediction methods.
- Advanced methods for evaluating the endurance of both Ships and Submarines.
- Launching calculations incorporate the McNeil method
Extensively used by the UK MOD and UK maritime industry, Paramarine is also in use in the USA, Canada, Norway, France and Pakistan.
