The invention relates to the technical field of offshore platform construction, and discloses an offshore platform installation ship, installation equipment and installation method.The installation ship is used for transporting an offshore platform to an offshore foundation and comprises a bow and a deck, and the bow drags the deck through a tow rope; the decks comprise the same number of active decks and passive decks, and the width of the decks is smaller than the distance between pile legs of the offshore platform. A rotary telescopic mechanism is installed on at least one side face of the active deck and comprises a locking rod, a telescopic motor and a rotary motor, a radial protrusion is arranged at the end of the locking rod, the telescopic motor is fixed in the active deck and is in transmission connection with the locking rod, and the rotary motor is fixed to the locking rod. The rotating motor is in transmission connection with the radial bulge; a locking groove is formed in at least one side face of the passive deck, and a blocking piece is arranged at a groove opening of the locking groove. The telescopic motor drives the radial protrusion to stretch into the locking groove, and the rotating motor drives the radial protrusion to rotate in the locking groove to abut against the inner side of the blocking piece.
