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 the US (whereby all the components were manufactured and warranted by the same manufacturer), JCB introduced the first dedicated backhoe loader (whereby the loader and backhoe were permanently attached to the chassis, allowing them to be more robust, rather than being demountable accessories for an agricultural tractor). In 1965, they would follow this with the world's first 360° excavator. The patent for the first reversible seat was developed at Wain-Roy by Carroll Arnold and Vaino Holopainen and then filed by Vaino under patent #2,784,768, and in June 1954, Vaino filed patent # 2,781,927 for individually controlled outriggers.
