An operator training simulator (OTS) is a computer-based training system that uses a dynamic simulation model of an industrial process, usually integrated with an emulator of the process plant's Distributed Control System (DCS).
Directional boring machine. Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring ...
The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [1] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for Operating Drills" [2] The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit ...
The DP operator (DPO) judges whether there is enough redundancy available at any given moment of the operation. IMO issued MSC/Circ.738 (Guidelines for dynamic positioning system (DP) operator training) on 24-06-1996. This refers to IMCA (International Marine Contractors Association) M 117 [21] as acceptable standard.
Using basic trigonometry, a three-dimensional plot of the path of the well can be produced. [citation needed] Essentially, a MWD operator measures the trajectory of the hole as it is drilled (for example, data updates arrive and are processed every few seconds or faster). This information is then used to drill in a pre-planned direction into ...
First, the operator surveys the area and the obstacle (road, sidewalk, driveway). Utility locators must supervise any underground work, and the path most clear of utilities is chosen to send the tool through. The first hole is dug on one side of the obstacle. This hole must be large enough to fit the tool and allow the operator to aim it.
Rotary assemblies [2] are commonly used where formations are predictable and the rig economics are an issue. In such an assembly the weight of the drill collars gives the BHA the tendency to sag or flex to the low side of the hole, collar stiffness length and stabiliser diameter and placement are engineered as a means of controlling the flex of the BHA.
Associated Training Services, commonly known as ATS is a heavy equipment training institution based in Sun Prairie, Wisconsin. [ 1 ] [ 2 ] It was founded in 1959 by Robert Klabacka as the National Institute of Concrete Construction.
