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
Backhoe stockpile, for picking up or filling material next to walls, to increase the reach of the machine, or working around obstacles such as pipes. Sometimes a backhoe arm is used as a crane, by slinging the lifted object from the support linkages behind the scoop (advisably not from the teeth). The backhoe's scoop may have a metal bar called a "thumb" hinged to the scoop. It grips against the scoop like a human thumb to pick up objects. Some types can lie back against the backhoe arm when not needed. Early development of hydraulic systems for what would become the
