Standard Horizontal Subsea Trees
Through standardized processes, common core components, and qualified, field-
proven assemblies, OneSubsea can design and deliver standard
horizontal subsea trees anywhere globally within 12 months.
These highly configurable solutions are
designed to bring greater efficiency and
reliability to subsea operations, enabling
project viability and helping you meet a
range of functionality requirements while
driving down capex.
Since the development of the SpoolTree*
horizontal subsea tree system in 1994,
OneSubsea has installed more than 1,000
systems around the world, making the
horizontal design an industry standard.
Horizontal subsea tree systems offer the
lowest initial capex and provide a universal
design for operational efficiency in multiple
fields. The latest evolution is the standard
horizontal tree, which utilizes existing
OneSubsea qualified and field-proven
technology that can be configured to meet
global functional requirements to deliver
maximum capital efficiency.

Advantages Flexible Functionality
Quality Control
The QC requirements for the subsea tree are in
accordance with API Specifications 6A and 17D.
Our facilities are certified per APIQ1, and our
strategic subcontractors are certified to ISO 9001.
Surveillance by independent competent bodies
facilitates preengineering of materials, which
enables preordering and, in certain cases, stocking
them to secure lead time and protect schedule.
Surveillance by customers is available during
factory-acceptance testing.
Materials
All material specifications used conform to
API 6A and API 17D and were chosen on a
component-by-component basis. Pressure-
containing components additionally conform
to DNV GL recommended practices (RP)
for steel forgings for subsea applications
(DNVGL-RP-0034). A range of standardized
material options is available based on
component criticality, manufacturability,
and environmental compatibility.
The standard horizontal tree is built from a suite of preauthored quality control, material, welding,
and coating specifications that simplify and expedite our execution processes. OneSubsea works
with approved vendors to ensure that they can manufacture the required components, enabling high
confidence in quality and lead time.
Welding
Our welding procedure for subsea trees conforms
to API 6A, ASME IX, ASME B31.3, and NACE
MR0175 / ISO 15156. Adhering to proven, tested,
and repeatable processes enables OneSubsea to
standardize welding specifications within and across
productlines and vendors
provide a superior engineering design that meets
or exceeds industry specifications at a lower cost
deliver increased value by enhancing the product
without incurring added costs.
There is one overall coating
procedure comprising two preferred
subsea coating systems—one
for temperatures up to 122 degF
[50degC] and one high-temperature
system for up to 302 degF [150 degC].
The standard coating specification
gives the requirements for surface
preparation, selection of coating
materials, application procedures,
and inspection of protective coatings
to be applied on the standard
horizontal tree.
