Hydrodynamics of an Installation Barge With Bilge Keels and Stinger

Multipurpose barges are used for accommodations, maintenance, equipment transport and installation and pipelay. For all these operations, the correct understanding of the motions of the vessel is essential for safety and to increase the uptime in the desired region. The motions of barges are well evaluated by the use of potential theory, but due to the presence of nonlinearities, asymmetries and devices such as bilge keels and stinger, the determination of the unit motions can be challenging, especially for roll motions. This work presents several results of motions, obtained from model tests and numerical calculations, for different configurations of a barge, with a focus on roll motion, but also considering heave and pitch, with and without the presence of bilge keels and stinger.
