These cable floats were manufactured by Resinex on account of SEA (www.seatrenching.com), a Ravenna based company specializing in the offshore business and were used in Egypt in 1999 and 2000.
The floats were used to house the umbelical cables of a sea-line trenching machine, yellow down to 50 meters, red down to 100 meters. In this case too, Resinex have chosen Nautex 25 to fill the semi-cylindrical shells.
