Experimental analysis of topside transportation with a double-barge float-over system

摘要

In this paper, an experimental investigation of the seakeeping behaviorrelative to a newly developed float-over concept by TechnipFMC ROCfor transportation, installation and decommissioning of off-shoreplatform topside is presented. A rigid scaled model of the float-oversystem was tested in the wave basin to determine the range of the seastateconditions under which the transportation of the topside can safelybe carried out in head and following waves. The present analysis is partof a more extensive experimental campaign which involves also the useof a scaled flexible physical (Dessi et al., 2017) and numericalsimulations for which the collected data provide a validation database.
