OFFSHORE TANKER-LOADING SYSTEM IS PROPOSED FOR ALASKA'S NORTH SLOPE BY M.B. GARNDE CO. INC.
A two-position, single-point, semibuoyant dock tank would revolve around a large, precast anchor embedded in the ocean floor. The anchor would contain a turntable carried on roller bearings and a buoyant riser hinged to the turntable. The turntable would allow the dock tank to adjust to horizontal current action, and the riser would allow it to adjsut to vertical tidal action. The anchor would take oil through a 48 in. dia line from onshore storage. Above the turntable deck, the main line divides into four 24 in. dia lines, each having a segment of flexible hose to permit vertical motion. The four 24 in. dia lines are contained within a buoyant arm riser, 8-9 ft in dia, for protection. The hull and bow of the semibuoyant dock would meet the same criteria as the hull of an icebreaker tanker. The design could solve the ballast treatment problem at the North Slope or elsewhere, and it would also permit maximum use of the underwater supply line. The use of extra pumps would make the tanker-loading rate considerably greater than the capacity of the supply line. Some further details of the system are described.
