  • Drilling riser retrieval in high current
    Patent number: 9080393
    Abstract: The disclosure is directed to a method for retrieving a drilling riser connected to a blow-out-preventer (BOP) located on a sea bed. The method includes the steps of: a) attaching the first end of the retrieval line to a vessel; b) attaching the second end of the retrieval line to a drilling riser; c) disconnecting the riser from the BOP; d) initiating the assent of the disconnected riser from the sea bed; e) maintaining tension on the riser as it ascends to the sea surface by creating a horizontal load that is opposite to a current load on a bottom end of the riser; f) releasing tension on the retrieval line as the riser approaches the bottom of the drilling vessel; and/or g) disconnecting the retrieval line from the riser, whereby the riser is pulled through the bottom opening in the drilling vessel.
