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

Features

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

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)
