A parasite mooring system is disclosed for restraining a compliant platform with respect to an auxiliary vessel. The parasite mooring system includes a parasite mooring line, a platform termination securing the parasite mooring line to the compliant platform; and a grip securing the parasite mooring line to a mooring line of the auxiliary vessel passing beyond the compliant platform. Another aspect of the present invention is a method for conducting offshore well operations in which a semisubmersible vessel is brought adjacent a compliant platform such that at least one mooring line of the semisubmersible vessel extends past the compliant platform and a parasite mooring line from the compliant platform is connected to the mooring line of the semisubmersible vessel. The parasite mooring line can then be tensioned to displace and restrain the compliant platform out of its normal position substantially over a well pattern and position the semisubmersible vessel over a selected well site within the well pattern at a location at the surface of the water which is not accessible to the semisubmersible vessel with the compliant platform in its normal position.

A parasite meeting system for restraining a compliant platform with respect to an auxiliary vessel, comprising: a donor mooring line which is played out from the auxiliary vessel and anchored to an ocean floor at a location beyond the compliant platform; an operable connection securing the donor mooring line of the auxiliary vessel to the compliant platform, said operable connection permitting tensioning upon the donor mooring line to shift the position of the compliant platform; and whereby the compliant platform is temporarily restrained out of its normal alignment with respect to the ocean floor through the donor mooring line.
