A subsea wellhead connection assembly 15 for establishing fluid communication and production capability between a subsea wellhead and an adjacent subsea manifold system includes a conduit 51 for fluidly connecting the wellhead and the manifold system, the conduit having one end 43 extending substantially horizontally and the other end 44 situated below the horizontal end 43. A wellhead connector 45 is fluidly connected to the other end 44 of the conduit 51 and serves releasably to connect the conduit 51 to the wellhead upon downward movement of the assembly 15 to establish fluid communication therebetween. A manifold system connector 56 is fluidly connected to the horizontal end 43 of the conduit 51 and serves releasably to connect the conduit 51 to the manifold system upon lateral movement of the manifold system connector 56 to establish fluid communication therebetween. A guide frame 60 is rigidly secured to the wellhead connector 45 for supporting the manifold system connector 56 and the conduit 51 and for vertically aligning the wellhead connector 45 over the wellhead and horizontally aligning the manifold system connector 56 with the manifold system. Installation of the assembly 15 involves lowering the assembly into the sea until the wellhead connector 45 is vertically aligned over the wellhead and the manifold system connector 56 is horizontally aligned with the subsea manifold system. The connector 45 is then releasably connected to the wellhead to establish fluid communication between the wellhead and the conduit 51, whereafter connector 56 is moved horizontally into operative connection with the subsea manifold system to establish fluid communication between the latter and the conduit 51. <IMAGE> |
