The CFD analysis helps assess hydrodynamic performance and structural safety, this was used recently to investigate the hull damage on HMS Northumberland which contributed to the MoD Board of Inquiry and the safety assessments of other Type 23 frigates. Cadence Design Systems Limited is the only supplier of this software. This software has been used for over 6 years and underpins current capability to move to an alternative software would require a) it to be compliant with the software test plan, b) be able to deliver on the military safety criteria the MoD uses and c) construction, & validation of a model of every RN Ship in the fleet. This whole transition would take at least 2years to complete and have to run both software side by side until all aspects of the transition were approved. This is unviable and therefore MOD’s requirement is to continue to use the CFD software. The resulting contract with Cadence Design Systems Limited, will be for the continued use of the current system, for annual Fine Marine CFD licence and 150 hours per year of advanced technical support. The continued use of CFD is essential for HM Ships and Submarines safety; Hydrodynamic analyses and ongoing defence investigation and assurance work. When Ship or Submarine hydrodynamic assessments are required CFD enables rapid root cause analysis and timely support to capability solutions, operational and safety decisions. CFD is not just a technical tool it is a mission critical capability which underpins the Royal Navy fleet safety, operational readiness, engineering assurance and defence decision making. Without the software, the MoD would face reduced confidence in HM Ships and Submarine safety, slower investigations and increased operational risk. ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 75220000 - **Delivery regions:** UK - **Delivery countries in notice:** GB ## Awards & Winning Suppliers (1) - **Award:** Cadence Computational Fluid Dynamics (CFD) Licence and Advanced Technical Support (pending) - Award id: `1` - Supplier(s): **Cadence Design Systems Limited** - Supplier identifiers: `GB-FTS-90474` - Value: £199,166 (exc.
