A drilling conductor supported within a suction anchor is installed by lowering the suction anchor through the top of a frame of a subsea processing unit. The base of the frame defines a landing area for the suction anchor and supports a fixing system 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 includes the conductor, the suction anchor and the frame. Additional equipment such as a blow-out presenter or a Christmas tree is lowered through the top of the frame and onto the conductor that is supported by the embedded suction anchor.
