Subsea tree systems

Subsea trees are required to control hydrocarbon production. These complex assemblies of valves and other components are installed at the wellhead to monitor and control production flow, and manage gas or fluids injection. Tree orientations can be either vertical, with production tubing suspended in the wellhead, or horizontal, with production tubing suspended in the tree. Design and materials are determined by operating conditions and the physical environment of each well (key factors include pressure, flow, temperature, and water depth).

Standardized and modular designs for consistency and speed

Baker Hughes completed its first subsea tree system installation in 1962. Since then, we have installed more than 1,400 subsea trees worldwide and are at the forefront of oil and gas field developments. Our trees are based on standardized, modular designs that drive high manufacturing efficiency and delivery speed. With make-to-order lead times  ranging from 10 to 14 months, we can help you minimize the time to first oil or gas, maximizing the returns on your project. Offering both 5-inch and 7-inch systems and up-to 15,000psi pressure rating—in a comprehensive range that includes gas-lift and electrical submersible pumps to maximize reservoir recovery —Baker Hughes has the tree system to meet your needs and facilitate control of intelligent completions in water depths up to 10,000 ft (3,048 m).

Features and benefits of our subsea trees include:
  • Modular design, reducing lead times but maintaining configurability
  • Designed for ease of installation
  • Reduced CO2 footprint
  • Strong legacy in key valve and connector technology, enabling high reliability
Industry-leading valve and connector technology

We have a strong legacy in key valve and connector technologies, ensuring we deliver trees with the highest levels of reliability and performance. Our latest trees exceed the American Petroleum Institute standard API 17D, and demonstrate our commitment to building systems with industry-leading products. For example, our VG300 valve design, of which there are more than 15,000 in operation, has been successfully tested to 1,200 cycles. This is double the industry-standard requirement and demonstrates the design’s reliability and robustness.
