Abstract:
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. In addition, the system includes a plurality of tensioning systems. One tensioning system is coupled to an upper end of each anchor. Further, the system includes a plurality of flexible tension members. Each tension member extends from a first end coupled to the subsea BOP to a second end coupled to one of the tensioning systems. Each tensioning system is configured to apply a tensile preload to one of the tension members.
