ABSTRACT:
An offshore oil well assembly is provided that includes a floating vessel and a coiled tubing injector supported on the floating vessel. A coiled tubing string is movable by the injector into and out of a wellbore. The assembly also includes at least one measurement device which, either directly or indirectly, measures a heave induced acceleration of the injector; and a control system which receives a signal from the measurement device indicating the heave induced acceleration of the injector, and transmits a command signal which causes a counteracting acceleration to be applied to the coiled tubing, wherein the counteracting acceleration is opposite to the heave induced acceleration experienced by the injector.
