Offshore oil drilling extracts oil from beneath the ocean floor, with fixed rigs or floating platforms used depending on location and conditions. Environmental concerns and safety risks are associated with the industry.
Offshore oil drilling is an oil extraction technique that allows oil companies to access deposits of oil buried beneath the ocean floor. Typically, offshore drilling sites are located on the continental shelf, although advances in drilling technology have made even further offshore platforms economically and physically feasible. Many people oppose offshore oil drilling, due to concerns about its impact on the environment and the unsightly appearance of offshore oil rigs.
Many sections of the Earth’s oceans have huge deposits of oil buried deep beneath their surface, and these oil deposits are extremely attractive to many oil companies. The first offshore oil drilling operation was established in 1938 in the Gulf of Mexico and other producers quickly began to follow suit in other regions of the world. By the 1970s, many communities had enacted specific bans against offshore drilling, and the issue became a bone of contention in some areas.
There are several ways an offshore oil drilling operation can be done, and the type of oil rig used usually depends on the depth of the location, the type of oil, and the prevailing conditions. Classically, fixed rigs are built on the ocean floor, with multiple wells and adjustable parts for engineers to extract oil from the surrounding area. Floating platforms are also used in some regions, and in some areas, offshore oil drilling is conducted on ships for even greater mobility.
Working on an offshore rig can be extremely dangerous. Several accidents have caused the rigs to explode, capsize, or be severely damaged, resulting in loss of life, and many crews today are housed off-site, so that if anything happens to the rig, the loss of life human will be less serious. Workers on oil rigs still have to contend with inclement weather, rig problems, and geological conditions that could become dangerous, and are typically highly paid in recognition of the industry’s risks.
The environmental effects of offshore drilling are mainly caused by pollution related to poorly managed and managed drilling rigs. Oil spills around rigs are common, especially on the seabed, where drilling can stimulate seepage and heavy metal pollution can also occur. Some people also believe that offshore oil drilling destroys and confuses marine life, although ironically, drilling rigs can also provide shelter for seabirds and fish.
