Definitions
- the present invention relates to the field of petroleum technology, and in particular to the field of subsea infrastructure for supply of fluids for subsea wells.
- the invention more par- ticularly relates to an apparatus for providing a crossover for a flow path for a fluid to a subsea device and a method of repairing a broken flow path for a fluid to a subsea device.
- Subsea petroleum system for oil extraction often requires fluids to be delivered from a topsides facility through an umbilical.
- These fluids may include e.g. a high-pressure hy- draulic fluid, a low-pressure hydraulic fluid, methanol, chemicals, and more.
- An umbilical may typically have two lines for each fluid to be delivered, so that there is a backup line should a line become damaged in any way that would make the line become unsuitable for transfer of a fluid.
- Two lines are reserved for each one of a plurality of fluids to be delivered to a subsea de vice, such as a subsea wellhead, through the umbilical.
- the subsea device receiving the fluids has an inlet comprising inlet connectors, wherein each inlet connector of the inlet is arranged for leading a fluid to the system in the device that requires said fluid.
- a backup line for another fluid could, in theory be used, but then the fluid would typically be delivered to the wrong sys- tern in the subsea device for that fluid.
- an apparatus for enabling sending a fluid to a receiver for the fluid in a situation where a main line for the fluid in an umbilical is faulty wherein the apparatus comprises:
- first inlet connector for connecting the main line for the fluid in the umbilical to the first inlet line in the apparatus and a second inlet connector for connecting a second line to the second inlet line in the apparatus;
- an outlet for connecting one or more receivers to the apparatus comprising a first outlet connector for connecting the receiver for the fluid to the apparatus;
- a switch mechanism for selectively switching from a default to a secondary setting, wherein in the default setting the first inlet line leads to the first outlet connector through the first outlet line, and wherein in the secondary setting the second inlet line leads to the first outlet connector through the first outlet line for enabling transferring the fluid through the second inlet line to the first outlet connector.
- A“faulty” main line may be a line that is damaged in any way such that the line may be deemed unsuitable for reliably transferring of a fluid through the line.
- the fluid may be a first fluid of a plurality of fluids being transferred through the umbilical and/or through other means to a receiver through the apparatus.
- the second inlet line may be an inlet line for a backup line in the umbilical.
- the second inlet line may be an inlet line for a main line for another fluid in the umbilical.
- the backup line may be a backup line for the fluid in the umbilical, or it may be a backup line for another one of the plurality of fluids.
- the apparatus may enable sending a fluid to a receiver for the fluid in a situation where both a main line and a backup line for the fluid in an umbilical is faulty, e.g.
- the second inlet connector is for connecting to a line that is originally intended as a main line or backup line for another fluid of the plurality of fluids, or for connecting to e.g. a secondary backup line for the fluid, or for connecting to e.g. another umbilical connected to the apparatus.
- the umbilical as referred to in this document, may be any type of hose or cable or umbilical or something substantially similar that may comprise a plurality of lines for providing flow paths for a fluid over a dis tance.
- the umbilical may connect the apparatus e.g. to an offshore platform or a surface vessel, or to a subsea hydraulic power unit.
- the receiver may be an inlet for a subsea device, and that the apparatus thus may e.g. be configured to be directly connected to the subsea device, or the receiver may e.g. be a cable, hose, an umbilical or something substantially similar to indirectly connect the apparatus to the subsea device.
- the apparatus when, in this document, references are made to the apparatus, it may be any one of or both of apparatus according to the first aspect of the invention, or the below- mentioned described apparatus.
- the apparatus may comprise an inlet that comprises the inlet connectors. Both the main line and the second line may be lines in one and the same umbilical, or they may be lines in different umbilicals.
- the apparatus may comprise a plurality of inlets.
- a further apparatus for providing a crossover for a flow path for a fluid to a subsea device, wherein the apparatus comprises: a plurality of lines for providing fluid paths through the apparatus;
- an inlet for connecting an umbilical to the apparatus comprising a plurality of inlet connectors, each one of the inlet connectors being arranged for connecting one of a plu rality of lines of the umbilical to one of the plurality of lines of the apparatus, for receiving in the line of the apparatus a fluid from the line of the umbilical;
- an outlet for connecting a receiver to the apparatus comprising a plurality of outlet connectors for connecting one of a plurality of lines of the apparatus to one of a plurality of lines of the receiver, for providing an outlet for the fluid in the line from the ap paratus;
- At least one switch mechanism for altering to which one of the plurality of lines in the re DCver one of the plurality of lines of the umbilical leads.
- the apparatus according to the first aspect of the invention may be highly advantageous in that it allows for, instead of replacing a faulty umbilical, which may be very expensive, simply operating the switch mechanism to enable sending the fluid to the receiver for the fluid through an alternative line in the umbilical.
- the apparatus may be arranged for switching a number of inlet connectors to any one of at least a selection of a plurality of outlet connectors, wherein each of said plurality of out- let connectors each leads to a receiver for a different fluid.
- the apparatus may thus ena ble sending a second fluid to a receiver for the second fluid, a third fluid to a receiver for the third fluid, and/or fourth fluid to a receiver for the fourth fluid, in a situation where a main line for the second, third, and/or fourth fluid is faulty, and/or in a situation where both a main line for the second, third, and/or fourth fluid is faulty.
- it may enable the same for a fifth fluid, a sixth fluid, and possibly even for one or more further fluids.
- each of the first, the second, the third, and the fourth fluid, and so on may be different fluids.

In yet other embodiments, the apparatus may have a higher number of outlet connectors than inlet connectors. The apparatus may have more than one inlet for receiving more than one umbilical and more than one outlet for connecting to one or more receivers.
- the apparatus may be said to be an apparatus for providing a crossover for a flow path for a fluid to a subsea device, as it enables switching to witch outlet connector an inlet connector leads, and thus to which outlet connector a line in an umbilical leads, and thus crossover a flow path from one outlet connector to another.
- the apparatus may be arranged to receive an umbilical for a subsea petroleum device, such as e.g. an umbilical for a subsea wellhead.
- the ap paratus may be arranged to receive an umbilical that may comprise one or more of a main high-pressure hydraulic line, a main low-pressure hydraulic line, a main chemical line, a main electrical power line, a main signal communications line, a main gas line for gas-lift gas and a main methanol line, and a backup-line for some, most or all of its main lines.
- a line in an umbilical“originally intended for” a fluid may be a main line or a backup line or both of a main and a backup line for said fluid in the umbilical - e.g.“originally intended” by the manufacturer or designer of the umbilical, or e.g. by an operator using the umbili cal.
- An umbilical may typically be designed such that all fluid lines or a number of fluid lines for different fluids are designed to withstand similar loads and/or are dimensioned equally.
- a first fluid such as e.g. a high-pressure hydraulic fluid or a methanol
- a line originally intended for another fluid such as a low-pressure hydraulic fluid or a chemical fluid
- An umbilical may typically be designed with a backup line for each of the main lines of the umbilical, wherein each main line is for transferring a type of fluid to a receiver for said type of fluid.
- a backup line for each of the main lines of the umbilical, wherein each main line is for transferring a type of fluid to a receiver for said type of fluid.
- Such a design offers a level of redundancy, in that if the main line becomes faulty, there will be one backup line available to transfer the fluid that was to be trans ferred in said main line.
- any backup line could be used to transfer the fluid that was to be transferred in said main line.
- the apparatus also enables the option to use an umbilical with a lower amount of backup lines yet still offer greater redun dancy than just one backup line per main line. E.g.
- an umbilical could have six main lines, and three backup lines, whereby going through the apparatus each of the three backup lines could function as a backup line for any one of the main lines.
- the apparatus could further enable using a main line for a second fluid as a backup line for a first fluid, e.g. in a situation where there is no longer a need for transferring the second fluid to a subsea de vice through the umbilical.
- the apparatus may comprise means for facilitating flushing of a line.
- the means may e.g. comprise a switch mechanism to direct a line in the umbilical to e.g. a dump tank or to a return line.
- the apparatus may comprise the dump tank.
- the dump tank may e.g. be a subsea dump tank for being placed subsea.
- the dump tank may comprise one or more sensors or transmitters for obtaining information about a content of the dump tank, such as e.g. a temperature, a volume of fluid or a pressure in the tank.

- the means for changing the pressure of a fluid may be used e.g. to increase the pressure of a low-pressure hydraulic fluid, so as to increase the pressure of the hydraulic fluid to a high-pressure level.
- each of one or more inlet connectors of the appa ratus may lead directly to one outlet connectors of the apparatus through a line of the apparatus.
- Each of one or more inlet connectors may be connected through a line of the apparatus to one or more valves. Each of said lines may lead, through the one or more valves, to two or more different outlet connectors.
- the apparatus may be configured for receiving an umbilical and connecting a line from the umbilical to a line in the apparatus, the line of the apparatus leading from the inlet to the outlet of the apparatus.
- the switch mechanism may be configured to change which outlet connector an inlet connector leads to.
- the apparatus may provide a crossover for a line from an umbilical, to facilitate leading a line in an umbilical to a line in the inlet of the subsea device that would not be connected to said line in the umbilical without said crossover. It may be used to provide a fluid or several fluids from an umbilical to more than one receiver, to isolate or reroute one or more lines and/or to test a line.
- an umbilical having six lines, wherein lines 1 and 2 are main and backup line for a high-pressure hydraulic fluid respectively, lines 3 and 4 are main and backup line for a low-pressure hydraulic fluid respectively, and lines 5 and 6 are main and backup line for methanol respectively. If lines 5 and 6 are broken, but all other lines are intact, the in vention offers an alternative to the prior art solutions of replacement of the umbilical, re pair of the umbilical, or the use of a tank placed on the seabed.
- the lines 1 , 2, 3, 4, 5 and 6 of the umbilical will lead to inlet connectors 1 , 2, 3, 4, 5 and 6 of the apparatus respectively
- inlet connectors 1 , 2, 3, 4, 5 and 6 of the apparatus will normally lead to outlet connectors 1 , 2, 3, 4, 5 and 6 of the apparatus respectively
- the outlet connectors 1 , 2, 3, 4, 5 and 6 of the apparatus will lead to inlet lines 1 , 2, 3, 4, 5 and 6 of the subsea device.
- the apparatus may provide a crossover, such that e.g.
- the backup line for the high-pressure hydraulic fluid can be used to deliver methanol to the correct inlet line of the subsea device. This can be done by rerouting the inlet connector 2 of the apparatus to outlet connector 5 of the apparatus instead of outlet connector 2. Outlet connector 5 of the apparatus will still lead to inlet line 5 of the subsea device. Thus, the umbilical line 2 will lead to inlet con nector 2 of the apparatus, to outlet connector 5 of the apparatus and to inlet line 5 of the subsea device, and thus deliver methanol from umbilical line 2 correctly to inlet line 5 of the subsea device.
- the invention may thus offer an elegant, time-efficient way to fix a problem where an um bilical can not provide a fluid path for a fluid to a correct inlet in a subsea device.
- the ap paratus may be installed precautionary, prior to damage to the umbilical, to be ready for providing crossover should one or more lines become damaged, or it may be installed when damage has already occurred.
