A drilling conductor (32) supported within a suction anchor (28) is installed by lowering the suction anchor through the top (18) of a frame (12) of a subsea processing unit (10). The base (14) of the frame defines a landing area for the suction anchor and supports a fixing system (54) for fixing the suction anchor to the frame. When the suction anchor has been embedded into the seabed beneath the processing unit, the frame is fixed to the suction anchor to form a structural unit that comprises the conductor, the suction anchor and the frame. Additional equipment such as a blow-out preventer or a Christmas tree (78) is lowered through the top of the frame and onto the conductor that is supported by the embedded suction anchor.
