The offshore industry primarily comprises of two industries - the offshore oil and gas industry and the offshore wind energy industry.
Due to ever rising demand for oil and gas in the world today, the global offshore oil and gas industry has been growing by leaps and bounds. The rising cost of oil and gas prices holds great promises for the industry in coming years. In this article, we will cover the various technologies, transportation mediums, and occupations associated with offshore industry.
Offshore platforms or oil platforms are giant structures used for the purpose of drilling and extracting gas and oil from wells, located deep beneath the ocean floors. These platforms have onsite processing and storage facilities, as well as provide accommodation for the crew. Offshore platforms are strongly built and are designed to last decades in the harsh environment. Depending on the requirements, they can either be floating or fixed to the ocean floor. There are different types of platforms that can be operated in a wide range of water depths from 200 to 12,000 ft. Among widely used oil platforms today are: fixed platforms, Compliant Towers, Semi-submersible Platform, Floating Production Systems, Tension Leg Platforms, Drillships and Spar Platforms.
Platform and ship
Offshore ships are those marine vessels which are specially designed to support the offshore oil and gas industry. They form the primary mode of transportation for carrying goods and workforce to oil stations deep inside the Ocean.
Some of them such as drillships are used as offshore platforms for oil and gas explorations and productions. Offshore ships can broadly be classified into Platform Supply Vessels (PSV), offshore barges, and all types of specialised marine vessels.
The offshore industry offers a wide range of occupations for entry-level as well as experienced professionals. Offshore jobs can be extremely challenging and may demand long working hours in harsh conditions. Shift work forms an integral part of offshore jobs, which usually is working offshore for 14 days followed by a 14 days rest period onshore. Offshore occupations include different levels of employments in the fields of oil and gas production and management. The main areas of operations here include drilling, rigging, surveying, piping, welding, diving, quality checks, as well as health and safety and cooking to name a few.
