Resumo

 The use of vertical connection module (VCM) has been the most conventional so- lution for direct lay-away connection between flowlines and subsea equipment offshore Brazil. A comprehensive study of the forces and moments exerted onto its gooseneck during the most critical phases of the connection is carried out herein, aiming at understanding their magnitude and sensibility to parameters such as pipe’s bending stiffness. Finite-element techniques are employed in a quasi-static model comprising VCM and its rigid gooseneck, end-fitting, bend restrictor, flexible pipe and winch cables.
