Title
(EN) HOLDING BACK ELONGATE ELEMENTS DURING SUBSEA OPERATIONS
(FR) ÉLÉMENTS ALLONGÉS DE RETENUE DURANT DES OPÉRATIONS SOUS-MARINES
Abstract
(EN) A subsea pipeline coated with a thermally insulating coating has a radially outer surface shaped to define external hold-back formations. In a J-lay operation, the weight load of a pipeline catenary is held back using a complementary bushing or clamp of an installation vessel engaged with the hold-back formations. The weight load is transferred from the catenary to the bushing or clamp by shear forces acting through the coating. The coating extends continuously along the pipe and is interposed between the hold-back formations and the underlying pipe. The hold-back formations may be integral with the coating.
(FR) Conduite sous-marine recouverte d'un revêtement thermoisolant comportant une surface radialement extérieure façonnée pour délimiter des formations de retenue externes. Dans une opération de pose en J, le poids de charge d'une caténaire de conduite est retenu à l'aide d'une douille ou pince complémentaire d'un navire d'installation en prise avec les formations de retenue. Le poids de charge est transféré de la caténaire sur la douille ou pince par des forces de cisaillement agissant par le biais du revêtement. Le revêtement s'étend en continu le long de la conduite et est intercalé entre les formations de retenue et le conduit sous-jacent. Les formations de retenue peuvent être solidaires du revêtement.
