Description
Subsea hydrogen distribution from decentralized producers
The present invention relates to a field configuration or layout of a pipeline system consisting of infield flowline and export pipeline in connection with a subsea inline manifold utilized in connection with a decentralized hydrogen producer at surface or at seabed, in particular for producing hydrogen or a mixture with hydrogen. The present invention is intended utilized for distribution of hydrogen from a number of decentralized hydrogen producers, typically in the context of a wind power farm, solar power, or wave/tidewater power farms.
In this context, related prior art can be found in, e.g., WO2020/095012 A1 disclosing an offshore wind turbine system for the large-scale production of hydrogen. The system includes a floating tower structure, a wind turbine generator, a lift pump, a desalination unit, an electrolysis unit, and an export riser. The hydrogen generated by the electrolysis unit is provided to the export riser for delivery to a manifold or pipeline that may be deployed upon the sea floor.
GB2299108 A and WO2018/045357 A1 disclose examples of subsea distribution networks in connection with hydrocarbon production.
WO2020/157509 A1, WO2016/044910 A1 and US2018/0371877 A1 disclose examples of subsea manifolds for oil and gas operations.
The present invention provides a subsea hydrogen distribution system for transport of hydrogen comprising:
- a number of hydrogen producers arranged at surface or at seabed in decentralized positions relative to a subsea inline manifold;
- a jumper/riser connecting each hydrogen producer with the subsea inline manifold;
- the subsea inline manifold comprising a manifold module and an inline Tee, the manifold module having a branch connection for each jumper/riser, the branch connections in flow connection with an infield flowline via a vertical up-facing hub integrated in the inline Tee; and
- the infield flowline connecting the subsea inline manifold to a pipeline end manifold or an export pipeline.
The manifold module comprises a compiler fitting formed with a vertical bore leading from an integrated or assembled down-facing connection to each branch connection, a manifold branch valve integrated with each branch connection. The down-facing connection is arranged for connection to the up-facing hub of the inline Tee. The inline Tee has an isolation valve integrated in the vertical up-facing hub in order to avoid flooding of the infield flowline while connecting or disconnecting the manifold module.
The present invention further comprises the following embodiments according to the appended subordinated patent claims:
- the manifold module comprises a lifting interface to allow a manifold lifting tool to be fixed to the manifold module for guiding, installation and retrieval;
- the inline Tee is designed with a rigid inline Tee header prepared with a flowline interface, such as a flange or other type of connection, at one or at each end, allowing a flexible infield flowline or export pipeline to be connected;
- the inline Tee is equipped with retractable guideposts to guide the manifold module during landing and retrieval;
- the inline Tee can be installed with or without the manifold module when laying out the infield flowline;
- a subsea boosting unit is connected to the export pipeline via inline Tees and upstream and downstream of an x-over valve allowing hydrogen flow to be routed via the boosting unit;
- the subsea boosting unit is arranged onto a fixed or floating unit at surface, and wherein a connection system allows flow to be routed to surface via risers.
The invention is driven to achieve a flexible and independent system, allowing the hydrogen production and distribution to start up at any stage in the field development unlike a daisy chain type solution where the producers must be installed in a fixed sequence or fully completed before the production can start. The only installation needed before start of hydrogen export is minimum one hydrogen producer 1, the infield flowline 4 with the inline-Tee’s, 9, and the manifold module 8 connected for the relevant producer.
The infield flowline 4, typical 8” to 16” to be connected to inline Tee’s 9 that are configured with a vertical inlet 17 of typical 5” to 7” bore with a manual isolation valve 15 with an integrated up-facing hub 16. The inline Tee 9 header 36 can either be welded or flanged to the infield flowline 4 via the flowline interface 35. A manifold module 8 with a compiler fitting 13 with two or more branch connections 12 to be landed vertically on the inline Tee 9 up-facing hub 16 and secured by a clamp, collet, or similar type of down-facing connection 14. Each branch on the manifold module 8 is equipped with a manifold branch valve 11 typically 2” to 4” bore. The compiler fitting 13 will be drilled with a vertical bore from the downfacing connection 14 and out to each of the branch connections 12 through the manifold branch valve 11. The manifold 8 can be installed together with the inline Tee 9 or separately. If the manifold module 8 is not installed a subsea cap can be installed on the Inline Tee 9 up-facing hub 16. The inline Tee 9 isolation valve 15 to be manually operated, the isolation valve 15 to be opened after the manifold module 8 is installed and secured in order to avoid the infield flowline 4 to be flooded with seawater, or hydrogen to leak out in case production is ongoing at other locations in the field. A lifting tool 41 is used to retrieve and install the manifold module 8. Guide sleeves 39 on the lifting tool 41 ensuring guiding towards the inline Tee 9. The Inline Tee 9 has two of retractable guideposts 43 for guiding of the manifold module. The retractable guideposts 43 are extended by tension from guide wires 37 anchored to the guidewire anchor receptacle 34 on the top of the retractable guideposts 43. Guide wire 37 can be used to guide the manifold module 8 or be removed after extending the retractable guideposts 43 if guide wires are not required.
A typical 2” to 4” jumper/riser 2 to be connected between the hydrogen producer 1 and the inline manifold 3, these connections can typical be a subsea remotely operated vehicle operated stab connection 33. The jumper/riser 2 to be a riser type if hydrogen producer sits on a floating unit or pulled through a J-tube in case the installation sits on a jack-up type foundation. A dry mate manual type connection can be used at the hydrogen producer end of the jumper/riser in a surface configuration.
The invention allows for a more optimized and standardized pipe sizing than a daisy chain solution as the jumper/riser 2 from each producer. Any start-up, maintenance, shutdown or removal of a hydrogen producer 1 will not affect the remaining production from other hydrogen producers 1 in the field as it can be isolated at the manifold module 8. Connecting the infield flowlines 4 into an export pipeline end manifold 5 also allows flexibility to start up production when installing only one infield flowline 4 and later implement additional.
The system is optimized to reduce the need for large flowline connections. The only flowline connections are between the infield flowline 4 and pipeline end manifold 5. The large export pipeline 6, typical 28” to 42” out from the pipeline end manifold 5 can be welded/connected at surface and installed as one unit and will also avoid any additional pipeline end termination and spool. The pipeline end manifold 5 can be designed as a sledge to take any possible temperature and/or pressure expansions.
The export pipeline 6 can be installed dry as there are valves 22 on each of the pipeline end manifold 5 branches. If required, a de-watering pig can be pre-installed inside the pipeline end manifold 5, pushing water back to shore or another subsea application if the export pipeline 6 requires to be flooded during installation. A retrievable pig launcher can also be installed for de-watering, but this will require an end connection and a valve on the export pipeline 6 end matching the export pipeline 6 size. De-watering of the infield flowlines 4 can be done by pre-installing a de-watering pig at the back end of the outermost inline manifold 3 and then run the pig towards the pipeline end manifold 5. An integrated pig stop can be installed at the pipeline end manifold 5 branch, preventing the pig from entering into the pipeline end manifold 5 inboard pipe. The pig can then be returned back to starting point and be secured by a manual operated pig stopper. An alternative can be to use a retrievable pig launcher at outermost inline manifold 3 with the impact of adding a connection system and an isolation valve matching the infield flowline 4 size.
All lines in the system e.g. jumper/riser 2, infield flowlines 4, and export pipeline 6 can be either flexible or rigid. Layout presented indicates flexible riser 2 and infield flowline 4, export pipeline 6 is shown as rigid.
A boosting station can be added in case of long-distance export line or if higher pressure is required for other reasons. The boosting station can either be added to the pipeline end manifold 5 or be included as a surface or subsea standalone boosting unit 25 in fluid connection with the export pipeline 6 downstream the pipeline end manifold 5. An inline Tee 27 upstream export line x-over valve 26 and an inline Tee 30 downstream the export line x-over valve 26 allow the flow to be routed via the boosting unit 25 when closing the x-over valve 26. The Isolation valves 29 to be closed when removing the boosting unit 25 or when not in service. Connection system 28 allow boosting station to be connected or disconnected. The connection 28 can be connected to a riser if the boosting station is located on a jack-up, floating unit or similar. This solution also allows the boosting station to be included at any time without disturbing the hydrogen production.
