Projects

In the second half of 2007, Nevesbu was contracted by Bluewater Energy Services in Hoofddorp, to design a rigid arm support structure for an external turret mooring for the FPSO Bunga Orkid, a vessel of about 300 m with a loading capacity of 300,000 tons.

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.
Nevesbu designed and engineered the rigid arm support structure as well as the bow cut-off and closure plating, involving a total of some 1500 tons of new steel. The work started with the conceptual design and analysis, and continued through to plans and reports for class submission.
