RISER TRANSFERRING SYSTEM, RISER WITHDRAWING APPARATUS, AND RISER TRANSFERRING METHOD USING THE SYSTEM IN DRILLING OFFSHORE STRUCTURE

摘要

The present invention relates to a kind of drilling installations of standpipe Transmission system, and use the standpipe transfer method transfer system of the standpipe. The present invention make stack rise to be transferred directly to aerial aisle without the use of joint boom crane which it is expensive and again under, the standpipe in order to stabilize ground is withdrawn. Moreover, the present invention can recall standpipe automatically, so that user not necessarily needs to, reduce the standpipe of moving distance and moving step, to significantly decrease time, cost and hour (M/H) consumption riser transmission work. ;The 2016 of copyright KIPO submissions
