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 various components are optimized for back-hoeing. Most backhoes are at their strongest curling the bucket, with the dipper arm next most powerful, and boom movements the least powerful. A backhoe loader is a tractor-like vehicle with a backhoe at one end, a front loader on the other and a swivelling seat to position the operator facing whichever direction is needed at the time. In North America, this arrangement is often referred to as simply a backhoe or, when on a chassis originally derived from farm tractors, a tractor loader backhoe (TLB). To differentiate, a backhoe on its own dedicated chassis
