Abstract
A cutting system is used for cutting a hollow cylindrical support beam which forms part of a support structure of a sea platform. The cutting system comprises a fixating device to fixate the cutting system in an operation position around an outer wall of the support beam, and a drilling device to drill a series of through holes in the outer wall and around the support beam. The drilling device is movable along a drill track and around the support beam by a drill driver.
