The Ninfe class of survey vessels [2] consists of two catamaran hulls operated by the Marina Militare Italiana.

Features

[edit]

They was designed to carry out hydro-oceanographic surveys at high sea and in harbours and shallow waters, in order to guarantee the production and updating of nautical charts.
Main activities:
[3]

  • sounding
  • minimum depth
  • topography of shorelines and port facilities
  • seabed features
  • collection of nautical and geographical data for the updating of nautical documentation
  • detection of sunken vessels or dangerous underwater obstacles

The collected data are then processed by means of dedicated software programs and then used to produce:

  • paper and electronic nautical charts for the safety of navigation
  • Additional Military Layers
  • nautical, scientific and technical documentation for mariners
  • oceanographic databases for scientific purposes

Characteristics

[edit]

It is fitted with:

  • multi-beam echo sounder Simrad EM300 (30 kHz)[4]
  • single-beam echo sounder Simrad EA500 (12, 120 e 200 kHz)
  • single-beam echo sounder Atlas Deso 25 (33, 100 e 210 kHz)
  • Side Scan Sonar towed Simrad MS992
  • differential and RTK satellite positioning systems
  • Sippican XBT MK21 bathythermograph system
  • CTD profiler with rosette system Ocean Seven 316 used for water sampling at different depths
  • Van Veen buckets
  • Sindel weather station

The ship is equipped one survey motor-boat for coastal and shallow water surveys fitted with:

  • single beam Simrad EA400 (38 e 200 kHz)
  • multi-beam echo sounders Simrad EM3000 (300 kHz)
