The subscript I stands for Mode I loading (unixial), while the subscript SCC stands for stress corrosion cracking KPI key performance indicators LMRP Lower Marine Riser Packageâthe upper section of a two-section subsea blowout preventer (BOP) stack consisting of a hydraulic connector, annular BOP, ball/flex joint, riser adapter, jumper hoses for the choke, kill, and auxiliary lines, and subsea control pods. This interfaces with the lower subsea BOP stack.
