摘要： The present invention pertains to the technical field of oil and gas; more specifically to the field of risers and flow line connections to offshore structures, and describes a pull-in cable deflector system in keelhauling of rigid risers comprising: a deflector assembly including a deflector device housed in a structural block, a sliding structure, at least two rails. The deflector device installed in the structural block is moved through a sliding structure on rails installed forward of the URB to the different pull-in or pull-out positions in keelhauling of rigid risers. The structural block is slidably mounted on a base frame by means of a system of sliding supports to perform a first adjustment of the transverse distance from the deflector device to the URB. The deflector device is then rotated around the vertical line depending on the azimuth of the support tube. A second adjustment of the transverse distance of the deflector device is performed during the pull-in operation.
