Refined characterisation of the site geology properties which may have impact on the structures of the neutrino telescope. Long-term time evolution of optical, oceanographic and environmental parameters of seawater (for instance, currents, temperature, salinity, light transmission, optical noise, acoustic noise, chemistry, radioactivity) in the detector region and at seafloor.
HCMR Survey of water properties and detailed sea bottom topography
CNR Oceanographic characterisation of deep-sea locations, evaluation of bio-fouling and corrosion effects at telescope structure
IFREMER Oceanographic characterisation biofouling
INFN Coordination of work package
INGV Geo-environmental characterisation of the sites through long-term time series monitoring
TECNOMARE Engineering work for the characterisation of sites, adaptation of an innovative nuclear spectrometer
UNIABDN Water column profiling of temporal and spatial variation in abundance of luminescent organisms at sites, studies on mobile deep-sea animals living in proposed observatory areas
Deep Sea Infrastructures
  • Design deployment procedures of detector parts
  • Study technologies needed (available or not) for
    deep-sea operation with the aim of optimizing
    them in order to reduce operations costs and time
  • Design infrastructures for
  • detector modules deployment,
  • detector modules (junction boxes, instrumented
    parts) handling
  • connection/disconnection, and eventually
    maintenance, of deep sea structure
  • visual inspection of deep sea floor and of
    detector parts.
  • Design/optimize stationary docking stations for
    an Hybrid System made by AUV and ROV

Design of deployment procedures for detector parts
IFREMER, IN2P3 Studies of deployment and recovery procedures, Design of components, costs evaluation.

Power Transmission system
Saclay, INFN, U-Athens
  • assess power consumption for each component and
    for the full detector
  • study the power distribution system from the
    on-shore laboratory to the single detector
  • define deep-Sea cables specifications
  • define deep-Sea connectors specifications
  • DC/AC energy transport ?? mixed DC-AC system ??
  • define, for each AC/DC power transmission
    condition, the characteristics required for the
    EOC and for the Connectors and/or Penetrators and
    of the associated electronics
  • study the environmental impact of each power
    transmission solution.
  • AC-DC conversion technologies
  • define characteristics of the real-time control
    system required from each AC/DC power
    transmission solution
  • technological limits to the total power

Definition of cables and connections

On-shore Infrastructures
  • define a conceptual design of the shore station
  • define the on-shore power distribution system
  • define the characteristics of the data
    transmission network needed to distribute data
    from the on-shore station to the external
    research laboratories
  • which technologies needed for data sharing ??

WP5 Kick-off meeting outcome
  • Start close organization between collaborating
  • Set-up coordination
  • Confirm agreement on proposed program of work and
    on objectives
  • Define a short term (3 months) agenda
  • existing deep-sea data assessment, definition of
    common analysis method, identification of needed
  • definition of long-term measurements for final
  • The work on other tasks need some imput from WP2,
    WP3, WP4, WP7, the activity will start in few

Risks connected to WP5 ?
  • Site characteristics study activity (spoiled by
    the site selection duty) can be successful for
    all quantities that have been already extensively
    measured and that do not need a long term,
    multi-year and multi-seasonal measurements
  • Detector deployment/handling tools design are
    design dependent but should not create problems
  • Deep Sea Infrastructure design, as well as power
    distribution, cables and connectors selection,
    will be based on commercial technology or, at
    most, on developments that do not need an out of
    the market technological effort
  • What we promised as deliverables in ANNEX1 can be
  • Present technologies are already sufficient for
    our needs but expensive, our work will be mainly
    devoted to simplify all deep-sea operation, to
    maximize the operative time, to reduce the
    operation costs

Docking system for AUV-ROV
A 3500m depth ROV design and construction is
already funded (project PEGASO funded with 5.6
Meuro by the Regione Siciliana) and under
realization by INFN and INGV (P.I.).
How many docking stations ? Where to place them ?
Which kind of connectors ? Which are AUV/ROV
critical parts ? How to improve their reliability
? How to control them ?
