What are the chains for on an oil rig?

A length of ordinary steel link chain used by the drilling crew to cause pipe being screwed together to turn rapidly.

Why do Roughnecks throw chains?

Conversation. A roughneck assembles a drill pipe by “throwing chain” to torque sections of pipe together.

Why do sharks hang around oil rigs?

Sharks come to these areas because of the abundance of food. Offshore oil rigs may also attract sharks with an abundant food supply, he said. The structures attract a wide variety of fish, providing plenty of meals for hungry sharks.

How do offshore oil rigs stay afloat?

Simple physics. As with oil tankers, heavy load barges and cruise ships, deep sea oil rigs float according to basic physics. As the weight of the rig pushes downwards displaced water pushes upwards, thus keeping the structure afloat.

What does throwing chains mean?

A throw chain is a small circle of chain, welded or attached to form a circle, that you project at. the dog’s rear end when it disobeys a ‘come’ command, or a ‘heel’ command, or otherwise ignores you. You can. make them yourself, or purchase them here: J&J throw chains.

How much do Roughnecks make?

Roughneck: As a roughneck you will be a member of the drilling crew. Job responsibilities include long and physically demanding hours, cleaning the rig, maintaining drilling equipment, and helping with transports. The average salary is $34,680, however, roughnecks can make up to $51,550 per year.

What does a Derrickman do?

The member of the drilling crew in charge of the mud-processing area during periods of circulation. The derrickman also measures mud density and conducts the Marsh funnel viscosity test on a regular basis when the mud is circulating in the hole.

Are sharks near oil rigs?

Last week, an oil worker on a rig offshore Louisiana took a footage of hundreds of sharks swimming around the rig in the U.S. Gulf of Mexico. Houston’s Chron has quoted a marine biologists and a shark expert who said that it is normal for sharks to swarm around oil rigs as they release organic waste into water.

Do oil rigs touch the bottom?

Mobile Drilling Platforms. A jack-up rig can raise and lower itself on three or four massive “legs.” Oil companies float these structures out to a drill site and then lower the legs until they touch the sea floor and elevate the rig out of the water.

Do oil rigs ever sink?

In early 2013, a brand new $40 million oil platform sank within few seconds during installation in the Persian Gulf. Belonging to Iran’s Oil Pars Oil and Gas Company, the oil rig sank even before the workers could get a chance to escape the disaster safely.

What is an offshore oil rig?

Offshore production platforms are modern marvels, but oil and gas cannot make it from below the seafloor to the consumer without human labor. In fact, larger oil rigs often employ more than a hundred workers to keep the platform running.

What equipment is needed to run an oil rig?

An uninterrupted power supply is essential for the oil and gas industry and lots of equipment on a rig needs powering. A lot of specialized, heavy equipment is used to drill the oil. This includes equipment such as a crane and hoisting system, large engines, a turntable and pumps.

What are the benefits of subsea cables for offshore oil rigs?

One of these methods is subsea cables. Subsea cables connect an offshore oil and gas rigs to onshore power sources. This eliminates platform CO2 emissions, increases space on the rig where a generator would normally reside, reduces the weight of the platform and makes the work environment safer and healthier.

What are the biggest challenges to offshore production?

One of the strongest challenges offshore production faces is finding a suitable, sustainable and cost-effective power source. Offshore oil and gas wells have shown to have a large amount of supply, but providing enough energy to power the rig to get that supply presents a unique challenge due to the offshore location of the rig.
