The Italian marine operator Bambini, based at the Port of Ravenna, operates an extensive fleet of vessels in support of the offshore industry. These range from tugs, to supply boats and crew boats. The latter, mostly in the 30 to 35-mrange, have been imported from US builders. Recently they launched their first Fast Supply Vessel, the 51.75 by 9.2-meter Blue Daddy, from the Cantieri Navail Vittoria in Adria on the Canal Bianco about 25 kilometers up from the Adriatic Sea along the River Po in north-eastern Italy.
