ABSTRACT:
An apparatus and method for offshore well operations in which a tension leg platform, a multiwell template means, and a riser system are arranged to provide: effective use of the advantages of a tension leg platform, a simplified riser design, and a novel template design which minimizes orientation problems of well equipment at the sea floor. A multiwell template means in which the template frame includes a latch ring member for each well to cooperate with a retrievable guide line base frame having releasable latch members whereby angular or radial orientation of the guide line base frame is not required with respect to the template frame. A retrievable guide line base frame having alignment means thereon and guide posts with guide lines attached thereto.
