Abstract
A method of using a semi-submersible tender with a deck, a shape that results in a combined environmental load less than 1000 kips in a 100-year extreme weather condition, a plurality of supports each with a rounded shape connected to the deck, a plurality of pontoons connecting the supports with each pontoon being capable of ballast transfer, wherein the tender is used for mooring in a tendering position relative to an offshore platform during a 1-year, 10-year, and 100-year storm, as well as non-storm conditions, using hawsers with adequate elasticity to accommodate the wave frequency between the platform and the tender and adequate stiffness to synchronize the mean/low frequency movement between the platform and the tender under an environmental load produced during a 10-year winter storm, and enough slack during a 10-year storm to enable the tender to move to a tender standby position, and wherein the tender uses an at least 6-point mooring system for creating global equilibrium between the platform and the tender.
