Abstract

1532246 Mono-mooring terminals DAVID BROWN-VOSPER (OFFSHORE) Ltd 31 Oct 1975 [8 May 1975] 45437/75 Heading E1H A marine terminal for tankers (Figure 1) comprises a tethered, totally submerged buoyant platform 1 which is tethered to the sea bed by tension legs, each joined to the platform by a universal coupling, from which extends at least one oil transfer hose (not shown) for connection to a tanker and further underwater piping to underwater oil well heads (not shown). As described a pair of pipes 12 are mounted on a concrete gravity anchor 3 and are connected at one end to pipes (not shown), leading from underwater well heads and at the other to two pipes in a riser 14. The riser 14 is connected by a universal coupling 16 to an upstanding central structure 15 on the anchor and its upper end is buoyant and passes through a central aperture in the platform 1. The platform 1 is tethered to the ground anchor 3 by tension legs 2 at a depth where it is substantially unaffected by wave action, the tension legs 2 having at either end universal couplings 4, 5. The couplings 5 are connected by bayonet connections to the anchor 3 and upper couplings 4 are connected to the platform 1 by parts 7 and transverse holding members 10. The platform 1 is hexagonal in plan view and comprises a peripheral buoyancy chamber 17 and a central platform (18). A rotary turntable is mounted on the central platform (18) and carries a mooring arm 25 and a manifold. Flexible pipes 21 connect the manifold to the two pipes of the riser 14 and oil transfer pipes (not shown) connect this manifold to the tanker. A marker buoy 50 is moored by a cable to the submerged platform 1.
