Figure F6. Photographs of Expedition 327 CORK umbilical bundles and tubing. A. Black umbilical flat pack containing one packer inflation line (½ inch) and two pressure monitoring lines (¼ inch), both stainless steel. B. Black umbilical flat pack containing three stainless steel geochemical sampling lines (all ½ inch). C. Microbiological sampling line (½ inch) made from inner PTFE tubing, braided steel jacket, and hard plastic outer shell. D. Inflatable packer elements were preconfigured with tubing pass-throughs for up to eight lines: packer inflation, fluid sampling (3), pressure monitoring (2), and microbiological sampling. E. Swellable packer elements were premachined to pass tubing umbilicals with slots that were premilled into the element housing. The casing below the elements was wrapped in the same swellable compound so that the elements would seal against the umbilical tubing from both sides once the material had a chance to react with seawater. F. Centralizers were placed on the CORK tubing to help protect the tubing connections from damage against the throat of the reentry cone or borehole wall during reentry. Pieces of the microbiological sampling line were used as flexible pigtail connections in Hole U1362B.
