Abstract:
A template system for locating pile structures for securing a tension leg platform hull with respect to an ocean floor, comprising:a well template for being fixed to an ocean floor; andat least one pile-driving template, each said pile-driving template having at least one coupling structure for operatively engaging a complementary coupling structure on said well template so as to determine a position of said pile-driving template relative to said well template, each said pile-driving template having at least one pile-driving guide for determining an installation location of a pile structure, whereby when said pile-driving template is coupled to said well template, said at least one pile-driving guide determines a position of the pile structure relative to said well template;wherein said well template includes a plurality of said coupling structures, whereby a said pile-driving template can be selectively and sequentially coupled at a plurality of positions around a periphery of said well template.
