After removal of the failed riser and drill pipe on the Horizon BOP, a capping stack sealed the top of the well on July 15, 2010, stopping the flow of oil into the Gulf of Mexico. The Q4000 was used in a successful static kill procedure, where mud, followed by cement, was pumped into the well, sealing the leak at the source.
TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...
The helix of a thread can twist in two possible directions, which is known as handedness. Most threads are oriented so that the threaded item, when seen from a point of view on the axis through the center of the helix, moves away from the viewer when it is turned in a clockwise direction, and moves towards the viewer when it is turned ...
Three electron emitters (for red, green, and blue phosphor dots); Electron Beams and Electron Guns; Focusing coils; Deflection coils; Connection for final anodes (referred to as the "ultor" [1] in some receiving tube manuals)
Helix Energy Solutions Inc., known as Cal Dive International prior to 2006, is an American oil and gas services company headquartered in Houston, Texas. The company is a global provider of offshore services in well intervention and ROV operations of new and existing oil and gas fields .
The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. [3] A circular helix (i.e. one with constant radius) has constant band curvature and constant torsion. The slope of ...
Pumps for modern direct-injection engines operate at a much higher pressure, up to 30,000 psi (2,100 bar) [2] and have configurations such as common rail radial piston, common rail two piston radial, inline, port and helix, and metering unit. Injection pumps are fuel lubricated which prevents oil from contaminating the fuel.
ROV at work in an underwater oil and gas field. The ROV is using a torque wrench to adjust a valve on a subsea structure.. A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...
