The game requires the player to maneuver the excavation probe, through a first-person view, through eighteen regions (in the shape of a rhombicuboctahedron) of the moon Mitral, and place a drilling rig in each of them to allow a minimum of 50% of the gas to escape. The position is established by a mixture of clues from the landscape (including an "X marks the spot" in the first zone) and trial and error. The security systems will attack Lesleigh upon sight, and he must disable or avoid them by any means possible. Only a few can be destroyed by shooting, the rest must be dispatched by mechanical means through switches or similar.
The eighteen regions are actually platforms above the true surface of Mitral; the excavation probe cannot fly or hover (although it can rise and lower itself slightly on hydraulics), and moving off a platform causes the player to fall onto the surface, where he is marooned. However, in one area the player can find a garage containing a hovering vehicle that can be used to explore and attack security systems, though not to place drilling rigs.
The driller is a team leader in charge during the process of well drilling. The term is commonly used in the context of an oil well drilling rig.
The driller is in charge of the crew, and running the rig itself. Most of the time, his or her job is simply to monitor the rig's activity, while the automatic driller runs the breaks and drills the hole. The driller is responsible for interpreting the signals the well gives regarding gas and fluids with high pressure. In an emergency he is also responsible for taking the correct counter measures to stop an uncontrolled well control situation from emerging. The driller will watch for gas levels coming out of the hole, how much drilling mud is going in, and other information. While tripping, the driller will run the floor and work the rig.
In the context of an offshore oil platform, the driller will be the one in charge of real time decisions. According to and, the hierarchy on an oil platform correspond to the timescale of which the sections operate. The automatic drilling equipment work on the timescale of seconds and both reports to and gets its orders from the driller, who operates on a timescale of several seconds to hours. The person will report and gets his or her orders from those planning the current drilling operation, on a timescale of days and weeks. The chain extends to those who are in charge of managing the whole oil field, on a timescale of decades.
Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.
"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.
