Italian survey company Lighthouse has expanded its fleet to meet market demand with the addition of a multipurpose offshore vessel, Nautical Geo.
Nautical Geo is a 74 meters long, DP2 class research vessel, fitted with equipment payload capable to perform a wide range of survey work, inspection and even light construction scopes.
A Teledyne Reson SeaBat 7150, a 12/24 kHz full ocean depth MBES is installed in the hull mounted gondola. An over the side mounted dual head 200/400 kHz Teledyne Reson SeaBat T20 should meet the shallow water requirements. Two EdgeTech 2000 DSS Integrated Sub-bottom & Side Scan Sonar systems, towed by a Romica hydrographic winch with 5500 m of armoured cable is used to provide seabed debris survey in shallow and deep water, while detection and mapping of ferrous objects (incl. UXO) is assured by two Geometrics G882 Marine Magnetometers. Subsea positionins and Ug for the towed sensors is provided by a Kongsberg HiPAP 502 SSBL, which is also the DP2 reference. Nautical Geo is permanently equipped with a Hi-ReHR seismic spread. Piston cores and PCPT are part of the geotechnical spread mobilized on board.
The survey and the processing rooms are fitted with all the necessary facilities for the acquisition and processing of survey data. The vessel can accommodate up to 46 persons.
