<p>A subsea well completion system, and components of such a system, are disclosed for handling marine well fluids from multiple subsea wells. The system includes a fluid-tight work enclosure hull containing manifold means, the hull having a plurality of radially-disposed lateral penetration means extending therethrough, the penetration means being operatively connected to the manifold means; and a base template having means for securing the template to the marine floor in a substantially horizontal position and having a lower support structure for supporting the work enclosure hull, the template further having an upper guidance structure comprising a plurality of substantially vertical guide members mounted in spaced radial array, each guide member extending inwardly toward the center of the template, forming an opening at the central portion of the template for receiving the work enclosure hull, a portion of the upper peripheral surface of each guide member sloping downwardly toward the opening for guiding the hull as it is lowered during installation of the hull onto the template. A method of establishing production capability from multiple subsea wellheads on a base template secured to the marine floor is also disclosed employing the aforecited system components.</p> |
