1. Nolwenn Chauché de Gesnais POLAR RESEARCH BEYOND THE EDGE
3. © Schaffer, Janin et. al. (2016) RESEARCH CONTEXT
4. DESIGN APPROACH: • FRUGAL RESEARCH • GOOD ENOUGH PRODUCT • RESILIENT BY DESIGN • DIVERT USAGE OF OTHER PRODUCTS • LEARN FROM OTHERS
5. HOT WATER DRILL: • HEAVY (REQUIRE LARGE CREW AND LIFTING GEAR) • NON/LIMITED MODULARITY © British Antarctic Survey
6. => LIGHT WEIGHT HOT WATER DRILL: • WEIGHT OPTIMISATION (50% ORIGINAL) • PRICE OPTIMISATION • SCALABLE • MANUALLY PORTABLE • ENERGY OPTIMISATION
7. UNDER WATER VEHICLE: • HEAVY (100+ KG) • AWKWARD SHAPE • TOO MUCH MODULARITY = COMPLEXITY • EXPENSIVE
8. => GROUNDING LINE REMOTE OPERATE VEHICLE • BASED ON EXISTING X300 FROM GRAALTECH • NO FINS/PROTRUSION • 5 KM FIBER OPTIC TETHER • 360° SONAR • LIGHT WEIGHT (57 KG)
9. SONAR • 110°-150° OF VIEWING ANGLE • ONLY LOOKING DOWN • HEAVY • BULKY SHAPE (CREATE PROTRUSION) • REDUNDANT ELECTRONICS IF LOOKING UP AND DOWN
10. => SONAR 360° • 360° VIEWING ANGLE • ALMOST CYLINDRICAL / LIMITED PROTRUSION • OPTIMISED NUMBER OF ACOUSTIC ANTENNAS • SINGLE ELECTRONIC BOARD FOR ALL SONAR RECEIVERS
11. => FJORD AUTONOMOUS UNDERWATER VEHICLE • CUSTOM DESIGN • NO FINS/PROTRUSION • ENERGY CONSUMPTION OPTIMISATION • 100 KM DESIGN RANGE • PORTABLE (65KG/2,6M) • DEDICATED TO ONE TYPE OF MISSION • USAGE OF SONAR DATA IN NAVIGATION
12. YEARLY ON THE FIELD INSTRUMENT: • LIMITED/NO DATA TRANSFER UNTIL PHYSICAL RECOVERY • EXPENSIVE/SLOW SATELLITE COMMUNICATION • LIMITED BATTERY IN WINTER
13. => REMOTE DATA UPLOAD: • USAGE OF NEW HIGH BANDWIDTH SATELLITE COMMS • FULL DATA TRANSFER FROM THE FIELD • REDUCED PRICE • WAKE UP /DEEP SLEEP FOR LOW ADDED ENERGYCONSUMPTION
14. POLAR RESEARCH BEYOND THE EDGE: • FRUGAL • GOOD ENOUGH • RESILIENT BY DESIGN • DIVERT USAGE OF OTHER PRODUCTS • LEARN FROM OTHERS
