Mondo and Saxi Batuque External Turret Mooring FPSOs

Between March 2006 and early 2007, Nevesbu designed rigid arm support structures for external turret moorings for the FPSOs Mondo and Saxi Batuque under a contract from Single Buoy Moorings of Monaco.

With an external turret, the bearing hangs in a kind of bowsprit, the 'rigid arm', which protrudes from the bow of the ship. Because of the angle at which the chains leave the turret, part of the bow must often be cut away at an angle to prevent it from colliding with the chains. More than 1,000 tons of new steel are easily needed for such a structure.
