MOBILE DRILL RIG [4 records]

Record 1 2026-01-08

English

Subject field(s)
  • Oil Drilling
CONT

Offshore units used by the petroleum industry to explore, develop, and produce oil and gas can be categorized as follows: 1. Fixed platforms, ... permanently attached to the ocean floor and ... not moveable. 2. Mobile platforms ... designed for mobility and intended to be at a given location a limited time period. The three general types of mobile platforms are: (a) the self-elevation units ; (b) the surface-type units (ship units and barge units) ; and (c) column-stabilized or semisubmersible units.

CONT

There are four basic forms of offshore rig :(a) Fixed Multi-well Platform ;(b) Mobile Jack-up Platform ;(c) Drill ship ;(d) Semi-submersible Platform.

CONT

As the men got farther out into the Gulf, they began to see many offshore rigs with their platforms, and tall derricks, where drilling was going on. Those on which drilling had finished and derricks were removed are also called platforms.

CONT

Destined for operation on Lake Erie this summer this offshore drilling rig built for Petrolia Oil Drilling Ltd. of Calgary by Davie Shipbuilding at Lauzon, heads up the St. Lawrence Seaway for final fitting at Port Maitland. The final overall width of the rig will be 134 feet, with 220-foot-long jacking legs extending to the lake bottom. Source: The Gazette 21-5-69.

CONT

On deep land rigs and on most offshore rigs there will be two 1300 or 1500 hp pumps.

CONT

More than half of the offshore rigs in operation are working in United States water, predominantly in the Gulf of Mexico.

PHR

Fixed offshore drilling platform.

PHR

Offshore fixed drilling plaform.

PHR

Offshore self-elevating drilling platform.

OBS

Strictly speaking, the platform and derrick are parts of a drilling rig.

French

Domaine(s)
  • Forage des puits de pétrole
DEF

Surface plate équipée de différents matériels servant au forage de puits de pétrole en mer.

CONT

Il y a aujourd'hui trois grandes familles d'engins de forage en mer : les navires de forage, les plates-formes auto-élévatrices et les plates-formes semi-submersibles.

CONT

[...] le SS-55T est utilisé pour des missions de desserte des plates-formes de forage pétrolier en mer [...]

OBS

Au sens strict, la plate-forme et le derrick sont des composantes de l'engin de forage.

OBS

Pluriel : des plateformes, des plates-formes.

OBS

plateforme (sing.); plateformes (pl.) : Ces graphies, puisées des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, sont attestées dans le Petit Robert (2004).

Key term(s)
  • plateforme de forage en mer
  • plateforme de forage pétrolier en mer
  • plateforme de forage sous-marin
  • plateforme marine de forage
  • plateforme offshore

Record 2 2011-05-09

English

Subject field(s)
  • Equipment (Oil and Natural Gas Extraction)
  • Oil Drilling
  • Petroleum Technology - Safety
DEF

A ram specially designed to cut through or shear drill pipe when the string is in the hole and it is necessary to seal the bore completely and quickly against high well pressure.

DEF

A closure mechanism on a well’s blowout preventer stack fitted with chisel-like jaws that are hydraulically operated. When the ram is closed on the pipe the jaws or blades cut the pipe, permitting the upper section to be removed from the BOP stack.

CONT

... shear rams cut through drill pipe and then form a seal.

CONT

Shear rams are used in mobile, offshore drilling operations to afford a quick method for moving the rig away from the hole when there is not time to trip the drill stem out of the hole.

Key term(s)
  • shear rams
  • shearing ram
  • shearing rams

French

Domaine(s)
  • Outillage (Extraction du pétrole et du gaz)
  • Forage des puits de pétrole
  • Sécurité (Technologie pétrolière)
DEF

Opercule d'un obturateur de puits muni de lames qui permettent d'assurer une coupure instantanée des tiges.

CONT

[Figure.] Obturateur double à mâchoires (dont un jeu de mâchoires-cisailles).

OBS

Les BOP [obturateurs de puits] fonctionnent à 1 500 psi (pression maxi de travail) sauf pour la fonction de cisaillage («shear-ram») de la garniture où la pression nécessaire peut être importante compte tenu de la résistance des tiges.

OBS

mâchoire de sécurité à cisaillement : terme confirmé par l'Institut français du pétrole.

Key term(s)
  • mâchoires de sécurité à cisaillement
  • mâchoires coupantes
  • mâchoires cisaillantes
  • mâchoires-cisailles

Subject field(s)
  • Types of Ships and Boats
  • Oil Drilling
DEF

A drilling rig used exclusively to drill offshore wells that floats upon the surface of the water when being moved from one location to another. It may or may not float once drilling begins.

OBS

The drill ship, semisubmersible drilling rig, and jackup drilling rig are all mobile rigs; a platform rig is not.
