Is the job of deep sea diver dangerous?
Yes, the job of deep sea diver is dangerous. Deep sea diving is the act of
diving below the surface of the sea to depths of more than 100 feet.
The deeper the diver goes, the greater the pressure of the water.
This pressure can cause a number of problems, including:
Decompression sickness (also known as the bends): This is a condition
that occurs when a diver ascends too quickly from a deep dive.
The nitrogen in the diver's blood forms bubbles, which can block
blood vessels and cause pain, paralysis, and even death.
Nitrogen narcosis (also known as rapture of the deep):
This is a condition that occurs when a diver breathes compressed
air at a depth of more than 100 feet. The nitrogen in the air can
cause the diver to feel euphoric, disoriented, and impaired in judgment.
Cold water shock: The water at great depths is very cold.
This can cause the diver to lose consciousness and drown.
Entanglement: Deep sea divers are at risk of becoming entangled
in fishing lines, nets, or other objects.
Hazardous marine life: Deep sea divers may encounter dangerous
marine life, such as sharks, jellyfish, and giant squid.
Despite the risks, deep sea diving is a necessary
job in a number of industries, including:
Oil and gas exploration and production: Deep sea divers are used
to install and maintain oil rigs and pipelines.
Underwater construction: Deep sea divers are used to build
and repair bridges, tunnels, and other underwater structures.
Scientific research: Deep sea divers are used to study
marine life and the ocean environment.
If you are considering a career as a deep sea diver, it is important
to be aware of the risks involved. You should also make sure that you
are physically fit and have the necessary training and experience.
When was the first oilfield dive in the Gulf of Mexico?
The first oilfield dive in the Gulf of Mexico was made in 1947.
A diver named Andrew Jackson "Jack" Hawkins was lowered into the
water from a boat to inspect a newly-completed oil well.
The well was located in 150 feet of water, and Hawkins was able to
successfully complete his inspection. This was a major breakthrough
for the oil and gas industry, as it showed that it was possible to
safely and effectively dive in the Gulf of Mexico.
Hawkins' dive paved the way for the development of the offshore
oil and gas industry in the Gulf of Mexico. Today, the Gulf of Mexico
is one of the world's leading producers of oil and gas,
and thousands of divers are employed in the industry.
When was helium first used as a diving gas?
Helium was first used as a diving gas in 1919. Professor Elihu Thomson of
the General Electric Company in Schenectady, New York, speculated that
helium could be used instead of nitrogen to reduce the breathing resistance
at great depth. Helium is a much lighter gas than nitrogen, and it does
not dissolve as easily in the blood. This means that it is less likely
to cause decompression sickness, also known as "the bends."
In 1924, the US Navy began examining helium's potential usage for diving.
By the mid-1920s, lab animals were exposed to experimental chamber dives
using heliox (a mixture of helium and oxygen). Soon, human subjects
breathing heliox 20/80 (20% oxygen, 80% helium) had been successfully
decompressed from deep dives.
Helium is now widely used as a diving gas, especially for deep dives.
It is also used in other applications where a lightweight, non-toxic
gas is needed, such as in welding and in breathing apparatus for astronauts.
