... from the subsea wellhead to the spar surface equipment. The production riser is essentially vertical and is supported near its top by a buoyancy can system. Thus, this production riser is described as a top tensioned riser system (TTR). The production riser systems includes a 13-3/8" outer riser, a 9-5...
