FloaTEC LLC has completed Phase-2 testing of its ultra-deepwater dry tree units, the Extendable Draft Semi (E-Semi) and the Truss Semi (T-Semi). The model test programs were conducted at the Bulgarian Ship Hydrodynamic Center in Varna, Bulgaria, and the Offshore Technology Research Center at Texas A&M University, respectively. Both designs are low-motion semis qualified to support dry tree risers in ultra-deep water up to 10,000 ft. A significant feature is the quayside integration capability, eliminating the need for a heavy-lift construction vessel offshore to install the topsides. The objectives of the in-place model tests were: To confirm applicability of the units’ design for Gulf of Mexico post-Katrina metocean conditions To confirm that the air gap is sufficient To verify numerical predictions of in-place global responses, including platform offsets, deck accelerations and mooring line/riser tension responses To measure the forces at the truss-hull connections, and riser top/bottom tension
