Title: Walter E Gray, Jr: Innovator in Pipeline Recovery Technologies
Introduction
Walter E Gray, Jr. is a notable inventor based in Santa Barbara, CA (US). He has made significant contributions to the field of underwater pipeline recovery, holding a total of 3 patents. His innovative designs have improved the efficiency and safety of retrieving submerged pipelines.
Latest Patents
One of his latest patents is the Pipeline Recovery Head. This device is designed to retrieve a submerged pipeline to the water surface. The recovery head features a center of gravity arm that helps maintain a level orientation, making it easier for divers or remotely operated vehicles (ROVs) to insert the head into the pipeline. Once inserted, the arm can be removed, allowing for unobstructed retrieval of the pipeline. The rear portion of the recovery head includes two T-posts that connect to oval links attached to a retrieving cable. This design ensures that the links do not slip off during the retrieval process.
Another significant patent is the Method for Recovering Wet Buckled Pipe. This method involves severing and recovering a submerged pipeline using divers or ROVs. A deflated lift bag is positioned under the pipeline and inflated to raise it off the sea floor. A cutoff saw is then used to sever the pipeline, after which a recovery head is aligned and activated to grip the severed end. Finally, a recovery cable is connected and retrieved, bringing both the recovery head and the pipeline to the surface.
