Abstract

AN OFFSHORE PLATFORM MAY INCLUDE A PAIR OF TROLLEYS. ONE TROLLEY MAY BE MOUNTED ON TOP OF THE PLATFORM AND THE OTHER TROLLEY MAY BE SUSPENDED BELOW THE PLATFORM. EACH TROLLEY MAY BE POSITIONED ON OPPOSED SIDES OF A MOON POOL IN ONE EMBODIMENT OF THE PRESENT INVENTION. THE LOWER TROLLEY MAY BE USED TO HANG OFF A RISER AND BLOWOUT PREVENTER. THE UPPER TROLLEY MAY BE UTILIZED TO HANG OFF SMALLER DIAMETER CASING WHILE LARGER DIAMETER CASING IS BEING MADE UP AND POSITIONED WITHIN THE HOLE. AS A RESULT OF THE PARALLEL OPERATIONS MADE POSSIBLE BY THE TROLLEYS, DRILLING TIME MAY BE REDUCED IN SOME EMBODIMENTS.
