Figure F2. Expedition 301 CORK bodies. A. Four CORK bodies secured to the top of the Core Tech shop, behind the rig floor, near the start of Expedition 301. The tops of the CORK bodies are at the bottom of the photograph, and first short sections of 4½ inch casing are visible at the top of the photograph, extending beyond the roof of the core tech shop, just below the CORK seals. The vertical cylinders on the left side of the image are casing hangers and casing deployment tools of various diameters. B. CORK being hoisted to the rig floor for deployment in Hole U1301B. The hole at the top of the CORK body will receive the instrument string and plugs. Visible on the right side of the CORK body is one of three instrument and access bays, each occupying 120° of arc and 1.5 m long. The bay visible in this photograph is for monitoring fluid pressure. Valves at the top of the bay (right side when CORK deployed vertically) control access and venting of the pressure monitoring lines, and the plate with holes at the bottom of the bay (left side when CORK deployed vertically) was designed to hold a pressure gauge and logging system.
