Based on their long established know-how regarding high speed ships, Piriou, Kership and the LHEEA research laboratory (research in Hydrodynamics, Energetics and Atmospheric Environment, Ecole Centrale de Nantes) joined forces to change the high speed ships design philosophy.
These highly versatile multipurpose vessels are designed to be deployed alternately for slow patrol missions, which represent 90% of their operation programme and require extended autonomy, for operations at very slow speed including deploying divers, handling equipment such as RHIBs or UAVs, and fast intervention missions such as fast deployment on operations areas, interception missions, whatever the weather conditions, extremely changeable and often unreliable.
To meet the challenge of maximal operability, the C-SHARP hull was developed to optimize global hydrodynamic performances of the vessel over a large range of speeds and operational conditions. For such purpose, the C-SHARP features a hydrodynamic fore bow with high lift-off capacity and an advanced hydrodynamic stern. These devices can be installed separately or in combination.
The C-SHARP hull has proved unequalled global performances:
- Autonomy increased by 10 to 30% thanks to significantly reduced resistance, especially at patrol speed
- Excellent seakeeping behaviour with 10 to 20% gain in accelerations
- Unequalled capacity to safely operate on-board equipment with approximately 20% reduction of wake and aft peak vertical accelerations as well as reduced relative movements between the ship and launched equipment
- Outstanding performances at higher speed, even on rough seas
The C-SHARP concept is currently being deployed on Kership vessels range and especially on coastal patrol vessels (CPV 25 and CPV 32) as well as high sea patrol vessels (OPV 45, OPV 52 and OPV 58). It is also perfectly adapted to modernization requirements on existing vessels (stern).
