- Subsea templates are large subsea structures that support or otherwise house wellheads, Christmas trees, and manifolds.
- a subsea manifold is made up of pipes and valves and is designed to transfer hydrocarbons from wellheads into a pipeline.
- the manifold is mounted onto the template, e.g., at the seafloor.

Abstract
Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 62/432,968, filed on Dec. 12, 2016, which is incorporated herein by reference in its entirety.
- Subsea templates are large subsea structures that support or otherwise house wellheads, Christmas trees, and manifolds. A subsea manifold is made up of pipes and valves and is designed to transfer hydrocarbons from wellheads into a pipeline. The manifold is mounted onto the template, e.g., at the seafloor.
- Generally, the subsea template includes a foundation that is at least partially embedded within the seafloor. More particularly, the foundation may include several pilings, which may be suction compartments (also referred to as suction anchors), e.g., positioned at the corners of the structure. The suction compartments have an open lower end, which is lowered, and then forced, into the seafloor, thereby anchoring the subsea template manifold in place.
- The remainder of the structure is built up from and supported by these suction compartments. A variety of truss-structures, support beams, etc., are connected to the suction compartments to provide the subsea template with sufficient stability and rigidity to allow for safe and effective operation of the subsea devices associated therewith. This can call for a large amount of material, which can be expensive in itself, and also can be expensive and time-consuming to build onto the suction compartments.
- Embodiments of the present disclosure may provide a subsea template manifold including a first suction compartment configured to be at least partially embedded in a sea floor, a second suction compartment configured to be at least partially embedded in the sea floor, and a bridging element extending between and connected to the first and second suction compartments. The bridging element is configured to be at least partially embedded in the sea floor.
- Embodiments of the disclosure may also provide a method for supporting a subsea manifold at a sea floor including embedding at least a portion of a suction compartment of a subsea template manifold into a seabed, and embedding at least a portion a bridging element of the subsea template into the seabed. The bridging element extends between and is connected to the first and second suction compartments.
- Embodiments of the disclosure may provide an apparatus for supporting a subsea well system, including a first suction anchor configured to be at least partially embedded in a sea floor, a second suction anchor configured to be at least partially embedded in the sea floor, and a bridging element extending between and connected to the first and second suction anchors. The bridging element is configured to be at least partially embedded in the sea floor.
- This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
- The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the present teachings and together with the description, serve to explain the principles of the present teachings. In the figures:

- The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, operations, elements, components, and/or groups thereof. Further, as used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context.
