ABSTRACT:
In underwater well installations of the type in which a template or like rigid base structure at the floor of a body of water defines a well opening, and an outer well member such as a suspension joint secured in the borehole projects upwardly within the well opening, the outer well member is connected to the template by a structure which restrains the outer well member from moving laterally relative to the base structure until the force tending to cause such lateral movement exceeds a predetermined large value, after which point the connection serves as a lost motion connection allowing the outer well member to move laterally through a limited excursion relative to the template.
