Introduction to Deep Offshore Technology
Industries are venturing outside of the continental shelves and into deeper water due to the growing need for global energy and resources. Deep offshore technology is a response to extreme conditions in deeper water. Deep offshore technology refers to the engineering of specific technologies, systems and techniques to access, explore and operate in extreme deep ocean environments – typically in excess of 500 meters and in some cases in excess of 3000 meters . Conventional processes are not effective in
deep ocean conditions. Deep offshore technology utilizes breakthrough engineering, specialized robotics and advanced data systems to execute multiple tasks safely and efficiently, including extracting oil and gas, undersea cable laying, and deep-sea science.From remotely operated vehicles (ROVs) to infrastructure that resists external pressures, deep offshore technology facilitates exploring the ocean floor, extracting key resources, and building underwater systems for global provision of communications, energy and transportation.
What Is Deep Offshore Technology?
Deep offshore technology relates to the advanced systems, tools, and engineering techniques for exploration, construction, and operations in the deep marine or water environment – normally defined as 500 meters or deeper. These technologies are required to support the oil and gas, renewable energy, telecommunications, and marine research industries. In deep offshore environments, human intervention is significantly limited due to the extreme and challenging underwater conditions of pressure, temperature, and geology. Therefore, most work will be done by a combination of machines, vessels, and real-time data, regardless of the location in the world where it is applicable.
Cutting-Edge Technology
