Description

FIELD OF DISCLOSURE

The present disclosure relates to a system and method for generating a predictive model configured to detect significant changes in pressure or temperature among pipe sections.

BACKGROUND AND SUMMARY

Leaks can be difficult to detect in areas with low visibility, particularly within bodies of water. To observe an underwater pipe section that may have a leak, typically an unmanned or remote observation vehicle (ROV) fitted with a camera would be the best option. However, these vehicles can be slow, inefficient, and require a significant amount of skill to operate. Even if an ROV can identity a specific leak, the ROV itself can only observe one section of pipe at a time. As a means of determining whether a leak is occurring, an ROV is not ideal.
Therefore, there is a need to identify leaks more quickly and efficiently.
Aspect of the disclosed embodiments include a system and method for detecting change in pressure and temperature among pipe sections.
Embodiments of the present disclosure include a system for detecting changes in pressure and temperature within section of a pipe, the system comprising one or more pipe sections comprising one or more valves further configured to open and close for a predetermined time period. The system also includes an administrator processor configured to open the one or more valves for a first predetermined time period and close the one or more valves for a second predetermined time period. Next, the system can record any changes in one or more pressure levels and temperature levels between the first predetermined time period and the second predetermined time period. Then, the system compares the recorded changes to one or more historical pressure levels and temperature levels and generates, upon comparing the record changes to the historical pressure levels and temperature levels, a predictive model configured to determine whether a significant change in the pressure levels or temperature levels has occurred. Next, the system can determine by the predictive model whether a significant change in the pressure levels or temperatures has occurred and close, upon determining that a significant change in the pressure levels or temperature levels has occurred, one or more valves.
Embodiments of the present disclosure also include a method comprising the steps of opening, by a processor, one or more valves associated with one or more pipe sections for a first predetermined time period and closing, by the processor, the one or more valves for a second predetermined time period. Next, the method proceeds with recording, by the processor, any changes in one or more pressure levels and temperature levels between the first predetermined time period and the second predetermined time period and comparing the recorded changes to one or more historical pressure levels and temperature levels. Next, the method proceeds with generating, upon comparing the record changes to the historical pressure levels and temperature levels, a predictive model configured to determine whether a significant change in the pressure levels or temperature levels has occurred. Then, the predictive model determines whether a significant change in the pressure levels or temperatures has occurred. Then, the method concludes with closing, upon determining that a significant change in the pressure levels or temperature levels has occurred, one or more valves.
Further features of the disclosed systems and methods, and the advantages offered thereby, are explained in greater detail hereinafter with reference to specific example embodiments illustrated in the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

In order to facilitate a fuller understanding of the present invention, reference is now made to the attached drawings. The drawings should not be construed as limiting the present invention, but are intended only to illustrate different aspects and embodiments of the invention.

The invention relates generally to generating a predictive model made to determine whether a leak has occurred, is presently occurring, or will occur.

Generally, the system can include an administrator processor and pipe sections. Certain pipe sections can further include a valve that can be opened and closed. Furthermore, the pipes can include a measurement device configured to measure pressure and temperature. The administrator processor can control the valves. The processor can begin by opening and closing the valves for a predetermined time period. The processor can observe and record any changes in pressure and temperature during the time period. Having recorded any changes, the processor can compare these records with historical data related to temperature and pressure. The historical data can be about different or similar pipe sections acting under similar or difference conditions. Upon comparing the current information to historical information, the processor can generate a predictive model configured to detect, based on observed pressure and temperature, whether a leak has occurred or will occur. The model can determine that a leak has occurred, then close the valve or section of pipe that is responsible for the leak.

Systems and methods of the present disclosure provide numerous advantages over typical methods. Rather than rely on an ROV to detect leaks, the predictive model can quickly alert users to potential leaks. This saves the user time and frustration. Furthermore, the model is not limited to a single section of pipe—it can observe many sections of pipe at once. The model can detect changes in pressure and temperature that are hidden from human observation. By learning from past data, the model can even predict when a small leak will become a big leak. Furthermore, the predictive model can consolidate data from other pipeline locations. Thus, information about leak-prevention can now be shared to anyone with authorized use. Overall, the disclosed systems and methods provide significant improvements on past solutions.

The network 120 may further include one network, or any number of the exemplary types of networks mentioned above, operating as a stand-alone network or in cooperation with each other. The network 120 may utilize one or more protocols of one or more network elements to which they are communicatively coupled. The network 120 may translate to or from other protocols to one or more protocols of network devices. Although the network 120 is depicted as a single network, it should be appreciated that according to one or more examples, the network 120 may comprise a plurality of interconnected networks, such as, for example, the Internet, a service provider's network, corporate networks, and home networks.

In some examples, exemplary procedures in accordance with the present disclosure described herein can be performed by a processing arrangement and/or a computing arrangement (e.g., a computer hardware arrangement). Such processing/computing arrangement can be, for example entirely or a part of, or include, but not limited to, a computer/processor that can include, for example one or more microprocessors, and use instructions stored on a non-transitory computer-accessible medium (e.g., RAM, ROM, hard drive, or other storage device). For example, a computer-accessible medium can be part of the memory of the contactless card 110, the user device 120, the server 140, the network 140, and the data storage unit 130 or other computer hardware arrangement.
In some examples, a computer-accessible medium (e.g., as described herein, a storage device such as a hard disk, floppy disk, memory stick, CD-ROM, RAM, ROM, etc., or a collection thereof) can be provided (e.g., in communication with the processing arrangement). The computer-accessible medium can contain executable instructions thereon. In addition or alternatively, a storage arrangement can be provided separately from the computer-accessible medium, which can provide the instructions to the processing arrangement so as to configure the processing arrangement to execute certain exemplary procedures, processes, and methods, as described herein above, for example.
The pipe section 150 can include one or more section of pipe connected together. The pipe sections can comprise one or more valves that can be opened or closed. The pipe sections can be associated with an oil well, oil pipeline, drilling operation, gas well, gas pipeline, water injection well, or water injection pipeline. The sections can be connected in party to a hydraulic power unit, one or more headers, a subsea control module, or valve actuators. The sections can be outfitted to transport one or more fluids. The valves can be configured to measure one or more elements of the pipes or areas surrounding the pipes. As a nonlimiting example, the valves can measure temperature, pressure within the pipe, visibility, the presence of other physical objects, salinity, the presence of other chemicals or fluids, seismic activity, and other observations. The pipes can have a wired connection to the administrator processor or server.
FIG. 2 is a flowchart illustrating a method according to an exemplary embodiment.
The method can involve communication between an administrator processor, one or more pipe sections, and a server. In action 205, one or more valves associated with one or more pipe sections can be opened. This action can be performed by the administrator processor. In action 210, the administrator processor can close the one or more valves that were opened in action 205. In actions 205 and 210, the valves can be opened and closed for a predetermined time period. The time period can be set automatically by a model or manually inputted. In action 215, the administrator processor can record any pressure and temperature changes. For example, the processor can record a drop or increase in pressure. Actions 205-215 can be iterated any number of times. Although FIG. 2 mentions only temperature and pressure, it is understood that the valves can record other elements including without limitation salinity, current, seismic data, visibility, liquid composition, and the presence of other physical objects. In action 220, the administrator processor can compare the recorded changes with historical data. The historical data can be retrieved from a data storage unit or server. The historical data can include temperature, pressure, salinity, current, seismic data, visibility, liquid composition, and the presence of other physical objects. The comparison can determine whether the current records are similar or different to historical data regarding potential changes on or near the pipe section. Upon comparing the current data to historical data, in action 225 the administrator processor can generate a predictive model configured to determine in action 230 whether, based on the current and historical data, a significant change in conditions have occurred. For example, the predictive model can determine that a significant drop in pressure has occurred. As another example, the model can determine that a sudden, unusual, or significant change in temperature or visibility has occurred. Upon determining that a significant change has occurred, the administrator processor can close one or more valves associated with one or more pipe sections. The processor can close a number of valves that are near or closely linked to a pipe section where a leak is occurring. After closing one or more valve, it is understood that the processor may monitor the valves and pipe sections to determine whether the significant change has subsided or otherwise been stopped. If not, the processor can again consult the model or otherwise determine how to proceed, including opening or closing more valves. In addition to closing one or more valves, the administrator processor can generate and transmit an auditory or visual alert in response to determining that there is a leak. The alert can be sent over a wired or wireless network. The alert can be sent to a user device or server.
FIG. 3 a-3 b illustrate a system of pipe section and an exemplary graphical record of pressure levels according to an exemplary embodiment. In FIG. 3 a , one or more sections of pipe can include a positive displacement pump that moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms or vanes. The pipe sections can further include a hydraulic power unit. When a hydraulic power unit begins functioning, the gear pump pulls hydraulic fluid out of the tank and moves it into an accumulator. A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. This process continues until the pressure within the accumulator reaches a predetermined level, at which point a charging valve switches the pumping action to begin circulating fluid. After the accumulator can be one or more headers such as header 1A and header 1B. Each of the headers 1A and 1B can include one or more valves configured to measure pressure.
FIG. 3 b illustrates an example of the recordation made by the administrator processor of the pressure levels from one or more valves. The graph of the pressure of header 1A illustrates a small, insignificant drop in in pressure. But the graph of the pressure of header 1B illustrates steep, significant drops in pressure. Thus, the predictive model may determine that header 1B is experiencing a leak. It is understood that the administrator processor can record the pressure of any number of pipe sections not including headers.
FIG. 4 illustrates an example of the pipe sections according to another exemplary embodiment. The pipe sections can include headers A and B. In addition to a hydraulic power unit, the pipe sections can include a subsea control module, and functions lines and actuators. The predictive model can work in concert with the pipe elements to determine whether a leak has occurred. The developed digitalization process and the algorithm quantifies the leakage rate, identifies topside header (branch) comparative consumption, and finds the leak's subsea source without using a flowmeter by just monitoring pressure sensors. The method is immune to sensor uncertainty. This method minimizes the need for costly ROV deployments and can eliminate the use of highly toxic UV-sensitive dye in hydraulic fluid. The algorithm uses the Hydraulic Power Unit pressure and header pressures and statistically correlates pressure signatures to detect leakage. The statistical method makes the algorithm immune to sensor drifts. The second example of leak detection with pressure coupling monitoring is subsea pipeline liquid dominant low rate production leak detection.
When production-filled pipeline isolated, during ESD (Emergency Shutdown), the subsea manifold pressure is different (usually lower) than the hydrostatic pressure due to specific gravity of the fluid, thermal cooling, and valve isolation sequence. However, if there is a pipeline leak, the manifold pressure couples with the hydrostatic pressure rapidly. By monitoring the pressure coupling behavior, one can detect even minimal pipeline leak rates.
Although embodiments of the present invention have been described herein in the context of a particular implementation in a particular environment for a particular purpose, those skilled in the art will recognize that its usefulness is not limited thereto and that the embodiments of the present invention can be beneficially implemented in other related environments for similar purposes. The invention should therefore not be limited by the above described embodiments, method, and examples, but by all embodiments within the scope and spirit of the invention as claimed.
The predictive models described herein can utilize a Bidirectional Encoder Representations from Transformers (BERT) models. BERT models utilize use multiple layers of so called “attention mechanisms” to process textual data and make predictions. These attention mechanisms effectively allow the BERT model to learn and assign more importance to words from the text input that are more important in making whatever inference is trying to be made.
The exemplary system, method and computer-readable medium can utilize various neural networks, such as convolutional neural networks (CNNs) or recurrent neural networks (RNNs), to generate the exemplary models. A CNN can include one or more convolutional layers (e.g., often with a subsampling step) and then followed by one or more fully connected layers as in a standard multilayer neural network. CNNs can utilize local connections, and can have tied weights followed by some form of pooling which can result in translation invariant features.
A RNN is a class of artificial neural network where connections between nodes form a directed graph along a sequence. This facilitates the determination of temporal dynamic behavior for a time sequence. Unlike feedforward neural networks, RNNs can use their internal state (e.g., memory) to process sequences of inputs. A RNN can generally refer to two broad classes of networks with a similar general structure, where one is finite impulse and the other is infinite impulse. Both classes of networks exhibit temporal dynamic behavior. A finite impulse recurrent network can be, or can include, a directed acyclic graph that can be unrolled and replaced with a strictly feedforward neural network, while an infinite impulse recurrent network can be, or can include, a directed cyclic graph that may not be unrolled. Both finite impulse and infinite impulse recurrent networks can have additional stored state, and the storage can be under the direct control of the neural network. The storage can also be replaced by another network or graph, which can incorporate time delays or can have feedback loops. Such controlled states can be referred to as gated state or gated memory, and can be part of long short-term memory networks (LSTMs) and gated recurrent units.
RNNs can be similar to a network of neuron-like nodes organized into successive “layers,” each node in a given layer being connected with a directed e.g., (one-way) connection to every other node in the next successive layer. Each node (e.g., neuron) can have a time-varying real-valued activation. Each connection (e.g., synapse) can have a modifiable real-valued weight. Nodes can either be (i) input nodes (e.g., receiving data from outside the network), (ii) output nodes (e.g., yielding results), or (iii) hidden nodes (e.g., that can modify the data en route from input to output). RNNs can accept an input vector x and give an output vector y. However, the output vectors are based not only by the input just provided in, but also on the entire history of inputs that have been provided in in the past.
For supervised learning in discrete time settings, sequences of real-valued input vectors can arrive at the input nodes, one vector at a time. At any given time step, each non-input unit can compute its current activation (e.g., result) as a nonlinear function of the weighted sum of the activations of all units that connect to it. Supervisor-given target activations can be supplied for some output units at certain time steps. For example, if the input sequence is a speech signal corresponding to a spoken digit, the final target output at the end of the sequence can be a label classifying the digit. In reinforcement learning settings, no teacher provides target signals. Instead, a fitness function, or reward function, can be used to evaluate the RNNs performance, which can influence its input stream through output units connected to actuators that can affect the environment. Each sequence can produce an error as the sum of the deviations of all target signals from the corresponding activations computed by the network. For a training set of numerous sequences, the total error can be the sum of the errors of all individual sequences.
The models described herein may be trained on one or more training datasets, each of which may comprise one or more types of data. In some examples, the training datasets may comprise previously-collected data, such as data collected from previous uses of the same type of systems described herein and data collected from different types of systems. In other examples, the training datasets may comprise continuously-collected data based on the current operation of the instant system and continuously-collected data from the operation of other systems. In some examples, the training dataset may include anticipated data, such as the anticipated future workloads, currently scheduled workloads, and planned future workloads, for the instant system and/or other systems. In other examples, the training datasets can include previous predictions for the instant system and other types of system, and may further include results data indicative of the accuracy of the previous predictions. In accordance with these examples, the predictive models described herein may be training prior to use and the training may continue with updated data sets that reflect additional information.
