  1. Technologies for Search, Assistance and Rescue Le Quartz Brest, France DETECTION OF SURVIVORS USING THERMO& NIGHTVISIONSYSTEM (UNDER DEVELOPMENT) Presented by Sebastian Ukleja Zbigniew Burciu, Teresa Abramowicz-Gerigk, Piotr Michna, Leszek Smolarek, Jarosław Soliwoda, Andrzej Szklarski, Sebastian Ukleja Gdynia Maritime University – Poland

  2. Detection of survivors using Thermo & NightVision System Stages of research Stage 1 – Thermovision as a sensor Stage 2 – Designing a system Stage 3 – Trials at sea

  3. Detection of survivors using Thermo & NightVision System -3,2°C 4,4°C 10 persons – just after manning 10 persons – 20 minutes later

  4. Detection of survivors using Thermo & NightVision System Trials at sea Life raft Distance: 0,5 nautical mile Distance: 0,6 nautical mile

  5. Detection of survivors using Thermo & NightVision System Thermovision as a sensor for SAR action • Searching during night time • Improved detection • Life rafts with survivors or not

  6. Detection of survivors using Thermo & NightVision System Stage 2 – Designing a system Phase 1 – System in outline Phase 2 – Where to install? Phase 3 – Compensation of ship motion Phase 4 – Selecting parts of equipment Phase 5 – Automatic detection

  7. Detection of survivors using Thermo & NightVision System Phase 1 – System in outline Sensors: thermo vision and night vision camera with stroboscope laser illuminator Special device to reduce effect of ship’s motion Monitor and control panel on the bridge Computer system for analysing images

  8. Detection of survivors using Thermo & NightVision System Stage 2 – Designing a system Phase 1 – System in outline Phase 2 – Where to install? Phase 3 – Compensation of ship motion Phase 4 – Selecting parts of equipment Phase 5 – Automatic detection

  9. Detection of survivors using Thermo & NightVision System Phase 2 – Where to install? Length:56,34 m Breadth:11,36 m Speed:12 knots Built inPoland in year 2000 The prototype of our system was installed on m/s Horyzont II

  10. Detection of survivors using Thermo & NightVision System Phase 2 – Where to install? • The best place to install: • Maximize field of vision • Reduce effect of temperature form funnel • Reduce effect of ship’s motions

  11. Detection of survivors using Thermo & NightVision System Phase 2 – Where to install? Point 3 - smallest effect of ship motions

  12. Detection of survivors using Thermo & NightVision System Stage 2 – Designing a system Phase 1 – System in outline Phase 2 – Where to install? Phase 3 – Compensation of ship motion Phase 4 – Selecting parts of equipment Phase 5 – Automatic detection
