2 S.BEURTHEY CPPM/IN2P3 Presentation Plan I.Introduction:  General remarks  Purpose of our study  Perimeter II.Technical requirements  External environment  Functional analysis III.Technical Organization IV.Concept description V.Development approach VI.Current development  Simulation  Design and prototype  Tests

3 S.BEURTHEY CPPM/IN2P3 I- General remarks This document is a part of ANEMONE development plan and a development status But Every thing can be modified in function of: New Collaboration KM3 Convergence needs Technical impossibilities or opportunities Design to cost balance

4 S.BEURTHEY CPPM/IN2P3 I- Purpose of study R&D study to increase crew safety and decrease cost of ANTARES installation (Cf. J. Roux presentation at AMSTERDAM meeting) Deliveries: All documents needed for final study of final line Prototype can be developed for concept validation

5 S.BEURTHEY CPPM/IN2P3 I- Perimeter (1/2) Defined by:  Mechanical structure supporting PM and electronic containers;  Inter-storey cables management;  PM and electronics containers ;  Tools and procedures for line installation.

6 S.BEURTHEY CPPM/IN2P3 I- Perimeter (2/2) Currently not included :  Hydro. comportment during line life;  ROV connection,  Structure life and material choice,  Cables and connectors;  Industrialization and integration.  Electronic,  Acquisition and transmission,  Instrumentation (PM, …),  Calibration, Science requirement … Collaboration needed to include some of these subjects KM3net WP output ANEMONE Constraints Strong interaction needed

7 S.BEURTHEY CPPM/IN2P3 II- External Environment Sea Cables Compact Structure Truck Boat Sea bed FP1 FC1 PM Crew FC2 FC3 FC4 FC5 FC6 FC7 Installation Phase:

8 S.BEURTHEY CPPM/IN2P3 II- Functional Analysis (1/3) FP1: Position PM in water  20 stages distant of 30m;  6PM storey;  No requirement for intra storey PM distance;  Horizontal PM orientation: 30° to 45°;  Vertical PM Orientation : equal repartition. FC1: Deploy line with bad weather condition  Weather condition : 25-30 kts;  Transfer duration <30’;  Depth < 4000m. FC2: Deploy several line per operation  5 structures on Castor : line surface <10m2 on boat;  Height<5m;  Adapted for a gantry crane < 5m.

9 S.BEURTHEY CPPM/IN2P3 II-Functional Analysis (2/3) FC3: Unfold line from sea bed  External release order;  Depth<4000m;  No intervention after release order;  Folded line recovery if requested. FC4: Group two PM in the same container  ANTARES PM type  Depth : 2500m  4000m  Cost: twice less than ANTARES solution (~2500€). FC5: Manage different kind of cables  Duration of cable arrangement <5’;  2 cables versions: ANTARES cable; 3 data cables (  10) with external mechanical cable (  10).  2 configurations: 30m between storey; Continuous cable (500m) with break out.

10 S.BEURTHEY CPPM/IN2P3 II- Functional Analysis (3/3) FC6: Reduce sea operation human risk  Minimize human intervention;  Classical crew operation  Only authorized staff FC7: Transport a complete line on standard truck  height<3m  Length<2,5m

11 S.BEURTHEY CPPM/IN2P3 III- Technical organization Tower structure Installation system Sea operation Cables arrangement cables management câbles Storey Container Bell Trigger system ConceptsQuality Hydro DW Tests coiling Projet Unfolding test ANEMONE

12 S.BEURTHEY CPPM/IN2P3 IV- Concept description (1/4) Compact line Fulfill Fc2, Fc6, Fc7 FC2: Deploy several line per sea operation FC7: Transport line by truck 2,5m 3m FC6: Reduce human risk (reduce handling)

13 S.BEURTHEY CPPM/IN2P3 IV- Concept description (2/4) Deployment Bell Tool for Fc1 FC1: deploy line with bad weather Different positions of line during free falling deployment Under crane deployment OR bell DWt Compact line buoy Release system Sea bed <15kts<30kts

14 S.BEURTHEY CPPM/IN2P3 IV- Concept description (3/4) Unfolded line: FP1 Not the right scale: ~30m between Each storey FP1: Position PM in water Risky development : Unfolding (FC3) and cable management (FC5)

15 S.BEURTHEY CPPM/IN2P3 IV- Concept description (4/4) Capsule for Fc4 This requirement is not strong. It is easy to replace a capsule by 2 spheres FC4: group 2 PM in the same container Torus 200mm Half sphere 17’’ Connector machined on torus

16 S.BEURTHEY CPPM/IN2P3 V- Development approach Three Working packages: Coiling development: »Test in air »Choice of some interesting coiling concept »Test in water »Not linked with capsule development Capsule development: »Simulation »Test Unfurling development: »Convergence discussion »Hydro simulation »Test in water (With final cable and capsule) »After Coiling and capsule development

17 S.BEURTHEY CPPM/IN2P3 V- Development Approach (2/2) Test «in air » Capsule development  Unfurling Test with deployment tool Test in «water »  Coiling faisability (if cable choice done) Tools conception Coiling Validation (with dummy capsule)  Convergence studies FEM Simulation Test Capsule faisability Qualification Preliminary Test Cable arrangement system design Unfurling validation Choice of some concept for water tests Hydro Simulation Preliminary Test  01/200901/2008 Choice of hydrodynamic concept Planning under construction/consolidation Cooperation needed Test on 2 storeys with partial bell  Structures manufacturing  Cable choice?
