Learn More About Our Subsea Products

Since the late 1800s, continued innovation has changed the way things are done within the oil and gas industry.

What began as piers and platforms to gain access to offshore oil evolved into large steel and concrete structures far from the coastline, and eventually floating platforms in order to drill in deeper waters.

In the 1970s and 1980s, companies began looking for better ways to access oil fields and combat water depth limitations. With the introduction of subsea equipment and technology, they discovered not only a more efficient and cost-effective way to access oil.

The Benefits of Subsea Sensors and Processes

Subsea processes and technology present a space-saving solution for offshore facilities around the world and can help reduce the complexity of operations.

For example, by utilizing subsea separation, you can reduce the amount of production transferred from the seafloor to the surface of the water. It also helps cut down on moving unwanted components to the facility on the water’s surface, just to direct them back to the seafloor for re-injection.

Typical subsea processes include:

  • Subsea water removal and re-injection or disposal
  • Single- or multi-phase boosting of well fluids
  • Sand and solid separation
  • Gas/liquid separation and boosting
  • Gas treatment and compression

In addition to the work flow benefits of subsea operations, sensors and transmitters can also help increase field recovery. They also make it easier to gain access to challenging oil fields, reducing additional spending for topside equipment.

Subsea processing equipment continues to play a vital role to the oil and gas industry and with continued innovation, it will continue to improve production rates within the market.
