Disclosed is a method of accessing a coil tubing unit located substantially at the top of a hybrid riser tower structure. The hybrid riser tower structure comprises a plurality of risers which are held vertically by a buoyancy module at their top. The method comprises attaching a line to a point near the top of said riser, and exerting a force on said line to pull said riser, or a top portion thereof, from its normal substantially vertical configuration to a configuration off vertical. |
