Definitions
- 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.
- 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.
- first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first object could be termed a second object, and, similarly, a second object could be termed a first object, without departing from the scope of the present disclosure.

- the suction compartments 102-108 may be hollow cylinders, which may be open at the bottom.
- suction compartments 102-108 may sink into the seafloor upon landing thereon during installation. Suction may then be applied to the upper end of the suction compartments 102-108 so as to drive the suction compartments 102-108 farther into, e.g., entirely into, the seafloor.
- the template 100 may also include a top plate 110, which may extend laterally (e.g., in a generally horizontal, parallel to the seafloor direction) between the suction compartments 102-108. Further, the top plate 110 may be coupled to the upper end of the suction compartments 102-108, and thus may be configured to be positioned slightly above or at the seafloor when the suction compartments 102-108 are installed in the seafloor. In some embodiments, the top plate 110 may be provided by several segments, one extending between each pair of adjacent suction compartments 102-108 as shown, but in other embodiments, may be a single plate.
- One or more bridging elements 112, 114, 116, 118 may extend between and be coupled to the suction compartments 102-108.
- respective ones of the bridging elements 112-118 may extend between two of the suction compartments 102-108.
- the bridging elements 112-118 may be coupled to the top plate 110, but in other embodiments, the bridging elements 112-118 and the top plate 110 may be separate.

- a washout sleeve 214, 216, 218, 220 may be positioned, e.g., between the two plates 120, 122.
- the washout sleeves 214-220 may be connected to the top plate 110 and/or one of the bridging elements 112-118. Further, the washout sleeves 214-220 may be connected to wells, and may represent the upper end of such wells (accordingly, in some cases herein, reference numbers 214-220 may be described as pointing to wells).

- the well-support brackets 250, 252 may be vertically-oriented plates, brackets, struts, etc. In some embodiments, the well-support brackets 250, 252 may extend downwards, and may be generally triangular, e.g., so as to facilitate extending and embedding the brackets 250, 252 into the seafloor. In other embodiments, the well-support brackets 250 may extend between the plates 120, 122, as shown, and extend upwards therefrom, such that the brackets 250, 252 may, in some cases, not be embedded in the seafloor during installation. The well-support brackets 250, 252 may thus provide lateral support and rigidity for the wells 214-220.
- Figure 2 illustrates a perspective view of the template 100, according to another embodiment.
- the template 100 omits the fourth suction chamber 108, and thus provides a generally triangular footprint. It will be appreciated that embodiments including five or more suction chambers 108, and any number of shapes for the footprint, are contemplated herein.

Figure 2 illustrates a perspective view of thetemplate 100, according to another embodiment. In this embodiment, thetemplate 100 omits thefourth suction chamber 108, and thus provides a generally triangular footprint. It will be appreciated that embodiments including five ormore suction chambers 108, and any number of shapes for the footprint, are contemplated herein. Further, in this embodiment, the bridging elements 112-116 (bridgingelement 118 may be omitted) may be generally constructed the same as one another, and may each include well-support brackets -
Figure 3 illustrates a perspective view of thetemplate 100, according to yet another embodiment. As shown, theplates plates support brackets plates 120, 122 (and thus the bridging elements 112-118) are connected to the suction compartments 102-108 via the connection with the wells 214-220. - With the wells 214-220 positioned (e.g., one each) between the suction compartments 102-108, the wellhead equipment may be similarly clocked at 90 degree angles. For example,

In some embodiments, the four wellhead devices 400-406 may each be a Christmas tree. Accordingly, the four wellhead devices 400-406 may each include a remote operated vehicle (ROV) panel 408,410, 412, 414. So as to allow for each of the ROV panels 408-414 to face outwards, each of the wellhead devices 400-406 may be rotated 90 degrees from the adjacent wellhead device 400-406. In some situations, this may allow for a morecompact template 100. - With continuing reference to
