Abstract
Official abstract text for this publication.
A method of remediation of a wet buckled pipeline uses a Submersible Vehicle (SV), Autonomous Underwater Vehicle (AUV), or Remote Operated Vehicle (ROV) and includes the steps of retaining an end of the buckled pipeline; cutting the buckled pipeline underwater below a damaged section of the buckled pipeline; attaching a termination to the cut end of the buckled pipeline; connecting a hydraulic pump to the termination; and running the pump to pull water out of the pipeline.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of remediation of a wet buckled pipeline using a subsea pipeline service skid comprising the steps of: retaining an end of the buckled pipeline above water and exposable to a source of surface gas that can enter the end of the buckled pipeline; cutting the buckled pipeline underwater below a damaged section of the buckled pipeline thereby generating a cut end of the buckled pipeline; attaching a valved closure to the cut end of the buckled…
