The buoy is anchored to the sea bed and linked to the platform, or in the case of SALM [single anchor leg mooring], to the well-head, by short pipeline.... Tankers are loaded through flexible or rigid loading arms which rotate to allow the vessel to take up the most suitable heading at some distance from the buoy.  1, fiche 3, Anglais, - single%20point%20buoy%20mooring%20system

Quel que soit le système de stockage en mer, il faut prévoir un ou plusieurs postes de chargement. De façon classique on utilise des bouées flottantes, ancrées sur le fond et qui servent d'amarrage unique aux pétroliers qui viennent charger; une telle bouée équipée pour recevoir des pétroliers de 240 000 tonnes, pèse environ 200 tonnes. Un flexible flottant relie la bouée à la plateforme de production. Il est de gros diamètre (30 à 40 pouces soit 75 à 100 centimètres) afin de permettre d'importants débits de chargement qui réduisent d'autant le temps d'immobilisation des navires.  1, fiche 3, Français, - amarrage%20unique

A flight director is a highly sophisticated system that electronically collects the information provided by a number of instruments, feeds this information into a computer and presents it in two visual displays. The two instruments that provide this visual display are a horizontal situation indicator (HSI) and an attitude director indicator (ADI). Usually the flight director installation is combined with an autopilot system. The entire package is then known as a flight control system.  7, fiche 4, Anglais, - horizontal%20situation%20indicator

Different manufacturers give other names to the components of their systems. The HSI is sometimes called the "pictorial navigation indictor" (PNI) and the ADI is sometimes called the "flight command indicator."  7, fiche 4, Anglais, - horizontal%20situation%20indicator

L'ensemble directeur de vol est un système très sophistiqué qui rassemble électroniquement l'information fournie par plusieurs instruments, introduit cette information dans un ordinateur et l'expose sur deux affichages visuels. Les deux instruments qui fournissent l'affichage visuel sont l'indicateur de situation horizontale (HSI) et l'indicateur du directeur d'assiette (ADI). Habituellement, l'ensemble directeur de vol est couplé au système de pilotage automatique.

Dead reckoning is a technique of computing the position of a vehicle from its distance and heading measurements. It is an inertial system which uses two independent sensors from which distance and heading information can be extracted. Because each position is relative, cumulative drift errors occur on an average of 2% of the distance traveled. The system consists of a magnetic compass or gyroscope for heading and odometer for distance. Dead reckoning is often combined with map matching to correct for drift errors. It performs well when combined with highly accurate digital maps. It can also be used to back up GPS during satellite visibility outages.  3, fiche 5, Anglais, - cumulative%20drift

To minimize cumulative drift, verticial gyros may be slaved, or caged, to the gravity vertical. Caging is automatically discontinued whenever the airplane is in a steady turn.  4, fiche 5, Anglais, - cumulative%20drift

A free gyro that is not slaved to any Earth reference (as the vertical and directional gyros and the gyrocompass are) will tend to maintain a fixed direction in inertial space, that is, with respect to fixed stars. Then as the Earth rotates, the angle between the axis of such a gyro and an arbitrary line on the Earth will change, and to an Earth-fixed observer the gyro will appear to precess.  3, fiche 6, Anglais, - slaved

South Pointing Carriage is the earliest known example of a land vehicle navigation system.... historical research has only recently established that [it] had nothing to do with magnetism, [but] was based on the principle(now called "the differential odometer") that for a given change in vehicle heading, a vehicle's outer wheels travel a mathematically predictable distance farther than the inner wheels. When changing heading, a gear train driven by an... outer wheel automatically engaged and rotated a horizontal turntable to exactly offset the change in heading... a figure with an outstretched arm mounted on the turntable always pointed in the original direction....  1, fiche 7, Anglais, - South%20Pointing%20Carriage
