Abstract

The present invention is directed to a heave compensating system for a floating drilling vessel. The system comprises: - a rig floor of the floating drilling vessel, - a drilling riser attached to a well via a wellhead, - a tubular extending through an opening of the rig floor, - a slips for holding the tubular, - a top drive and/or an elevator for holding the tubular at an upper end, - a telescopic joint comprising an outer barrel and an inner barrel, wherein the outer barrel is connected to a wellhead, and the inner barrel is telescopically arranged inside the outer barrel, - a riser tensioning system arranged between the drilling riser and the floating drilling vessel, wherein the heave compensating system comprises a draw work heave compensating system arranged between the top drive and/or elevator and the rig floor, and a slips heave compensating system for heave compensation of the slips, wherein the heave compensating systems may be synchronized, compensating for the floating drilling vessel's heave movement.
