3503-1 SEDCO 712 BOP – MAERSK COMPONENTS FOR ASSEMBLY INCLUSION

Upcoming drilling operation requires the swap out of existing VETCO wellhead connector with MAERSK supplied CAMERON connector. Along with the new connector, MAERSK also supplied guide funnel to be incorporated in to new BOP wellhead frame assembly for the guideline-less re-entry. At the fabricator facility, these two components were laser scanned for inclusion in to the final assembly and fit up of the new wellhead frame. This colour laser scan data was also subsequently used as BOP General Arrangement / Stack Up CAD drawing and for subsequent dimensional interrogation in the future, should the needs arise. Guide cone scan was then used to generate Finite Element Assessment (FEA) Model for the funnel strength verification when the funnel is subjected to re-entry loads during the sliding contact between the wellhead and the guide funnel while the BOP is being aligned with the wellhead. For more information of the wellhead frame that house these components, refer to 3503-2 Sedco 712 BOP – TOI New Wellhead Frame video in this section.
