摘要： A system for tethering a subsea blowout preventer (BOP) includes a plurality of anchors disposed about the subsea BOP and secured to the sea floor, a plurality of tensioning systems, and a plurality of flexible tension members. Each tensioning system is coupled to a frame of the BOP and is configured to apply a tensile preload to one of the tension members. Each tension member is coupled to one of the anchors and extends from a first end coupled to one of the tensioning systems to a second end coupled to an anchor.

摘要： A pile top assembly includes an adapter configured to couple to an upper end of a subsea anchor, a tensioning system mounted on an upper end of the adapter, and a flexible tension member having a first end coupled to the tensioning system. The tensioning system is operable to pay in and pay out the flexible tension member relative to the tensioning system. The pile top assembly further includes means coupled to the adapter for selectively engaging the upper end of the subsea anchor.

摘要： A marine riser having a pressure level rating of twenty ksi or more includes riser tubulars and auxiliary lines that are made of steel having an API grade C110 and C125 and is NACE certified. The riser tubulars and auxiliary lines are not welded, but are assembled via threaded, clamped, stabbed or other mechanical and/or hydraulic connections. Some of the connections may be pre-assembled to reduce assembly time on the drill ship.
