The IPVs are specifically designed for use by coast guard agencies and navies across the globe. The vessels are intended to carry out typical missions such as maritime patrol, search-and-rescue (SAR), and protection of economic waters.
Defence products procurement agency Armscor placed an order with Damen Shipyards Cape Town (DSCT) for the supply of three IPVs for the South African Navy, in February 2018. The order forms part of the navy’s Project Biro, which aims to counter illegal activities in territorial waters.
Stan Patrol 6211 IPV design and features
The Stan Patrol 6211 IPV incorporates the Sea Axe Bow design developed by Damen in collaboration with the Delft University of Technology. The Sea Axe Bow design ensures improved seakeeping characteristics.
The vessel will incorporate a steel hull and aluminium superstructure. The hull will improve stability and reduce slamming when travelling at higher speeds. Advanced seakeeping capabilities and wheelhouse position will enable the vehicle to achieve maximum operational ability.
The simple and sleek design will further reduce the resistance experienced by the vessel, enhancing its fuel efficiency. Ergonomic features and low vibration noise levels of the IPV will offer a secure and comfortable travel experience to the on-board crew.
Classified by Bureau Veritas as a lightship / fast patrol boat, the boat can accommodate a crew of up to 62 members in the cabins located in the first, main and below main decks. The vessel will have a length of 62.2m, maximum draught of 4m and overall beam of 11m. The fuel tank and fresh water tank capacities of the vessel will be 85m³ and 30m³, respectively.
Optional equipment and systems on-board the IPV will include a sewage treatment plant, fresh water maker, interceptors, second searchlight, night vision equipment and additional radar. The vessel can be further installed with military equipment / ballistic protection systems based on the mission requirements.
Navigation and communication systems
The navigational requirements of the patrol vessel will be served by a chart plotter, X-band and S-band radars, electronic chart display and information system (ECDIS), magnetic compass, gyrocompass, and GPS module.
The automatic identification system on board will avoid possible collisions during operations. The Stan Patrol 6211 IPV will also feature an advanced autopilot system and echo sounder.
Communication systems to be installed in the IPV include an external global maritime distress and safety system (GMDSS) A3 system, Iridium satellite telephone, and very small aperture terminal (VSAT). A Fleet broadband system will further enable the crew to stay connected with the external world.
Stan Patrol 6211 propulsion and performance
The Stan Patrol 6211 IPV will be powered by four MTU / CAT engines, which will be capable of producing a total power output of 11,520bkW.
Each engine will be coupled to a fixed-pitch propeller (FPP) through a Reintjes WVS series gearbox. The vessel will also integrate a hydraulically driven fin stabilisation system and two 120kW bow thrusters for high manoeuvrability.
The power plant will enable the boat to sail at a maximum speed of 26.5k and achieve a maximum range of up to 4,000nmi at full speed.
