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 filed a patent #3,249,244 for the first extendible boom. Patent #3,273,729 was filed in January 1965 by Vaino J. Holopainen for the first hydraulic thumb. Although Wain-Roy Corporation no longer exists, the Wain Roy product line of backhoe attachments and couplers is still available through the Woods Equipment Company of Rockford, Illinois, US. Because of the long-time predominance of the JCB marque in the United Kingdom and Ireland, it has become a genericized trademark there, and backhoe-equipped diggers are commonly called JCBs, while the term "backhoe" as an excavator component is almost unknown to the general public in this context.
