Normally unmanned installation Normally unmanned installation A Normally Unmanned Installation (NUI) is a type of automated offshore Oil/Gas platform designed to be primarily operated remotely, without the constant presence of personnel. These generally were characterized by their small size, often consisting of just a well bay with a helipad on top. They are often a compromise of providing the convenience of surface wellheads, which are easier to build and maintain, while avoiding the high operating costs of a full production platform. They are generally only used in shallower water, where constructing many small NUIs is a relatively easy and cheap option as compared
Rear naked choke Rear naked choke The rear naked choke (RNC) is a chokehold in martial arts applied from an opponent's back. The word "naked" in this context was suggests that, unlike other strangulation techniques found in Jujutsu/Judo, this hold does not require the use of a keikogi ("gi") or training uniform.
