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-view mirrors come in various shapes and designs, and have various methods of mounting the mirrors to the motorcycle, most commonly to the handlebars.
