The Process of a Plant Shutdown in 2016

A plant shutdown is common to be happened several times during the company’s lifetime, it would be for scheduled maintenance, replacement of parts, modification or expansion. No matter what the reason is, the main challenge is to stick with the most appropriate safety standards and keep downtime to a minimum. If the company wants to achieve that goal, then all of logistical processes, which is consist of the lifting, transport, installation and removal of many components, are all the important factors and has interdependent role. However, many refineries were not properly planned with plant shutdown procedure. Just to add more into shutdown complexity, the fact that in this kind of projects, multiple parties are demanded to work almost simultaneously at the same site. With these facts in mind, the new and comprehensive approaches should be taken into account, not just the ways to move the different components, but also the safety procedure and coordination of activities which will be carried out each by different subcontractors.

Basically there are five phases of plant shutdown:

1. Planning

In this phase, the internal team of the refinery, the main contractor hired for the project, and various engineering department, both internal and external, will determine the range of work that needs to be done, the pre-shutdown activities, and general logistics. You will need a lot of human resources to get the job done. then , the key officers will negotiate the schedule. The prime contractor would propose the time required to carry out the project without taking toll on the resources and result in critical tasks to be rushed.

2. Coordination

In this stage, the team would determine the order of things that should be done, the responsibility of each unit, and more detailed work flow. This involves the entire shutdown team: internal staff (maintenance, engineering, facility management, and procurement), external engineers, contractors, and vendors. This is the most crucial and longest phase. In this phase, the team would discuss and decide on which equipment and systems will be both removed from and returned to service.

3. Procurement

More details to the procurement of equipment and materials, this phase involves contracts bidding or negotiation with all important consultants, contractors, and vendors. In this phase, you will be the main decision maker, project management, facilities, and the procurement or purchasing department. This process could take several weeks depending on the flexibility of the personnels and outsources involved. If you make agreement with foreign contractors, make sure that you have the copy in their native language, or a language that is understandable by both parties to make sure there will be no misconception once the project has started.

4. Execution

Just as the name states, this is when the process commencing. All procedure will be put in place including new and old equipments. The time it takes would be depending on the range of work and the schedule that was negotiated with the higher ups.

5. Return to Service

All the process is done and you will start the refinery anew. Several tests should be conducted to ensure the performance of the machines, including the environmental monitoring and similar. Once reliable test results are received, the refinery will be ready for use.

Open Hole Wireline Logging

Open hole wireline logging is very important for oil drilling, and that is very important so that people can set up the wells that they are working on. There are some ways to make the well as safe as possible, and you need to be sure that you have thought really hard about how you are going to be able to use the logging system to make the system safe. This means that you will be able to use the logging to figure out what is going on with the well.

The logging is going to help you make sure that you know where the well is going to sit, and it is going to tell you the depth and size of the well. You need to know this information so that there is no confusion for the future, and you also need to make sure that you are going to be able to get the well on line as soon as you can.

You also need to make sure that you keep doing the logging for as long as possible so that you have information on the well that is current. Someone who is not taking information on the well is going to have a hard time figuring out what is going on with the well. You need to have a clear safety record for the site, and you will be able to keep track of that record so that there is no problem in the future. You can show that you did the logging, and you can show that it was done for the good of everyone on the crew. You will be able to get the exact results you need for the well, and you will be able to prove that your well is up the safety standards of the industry.

Wireline Companies offer exceptional services to oil and gas industry

Wireline companies offer services that are very useful for the oil and gas industry. Basically, wireline logging is a sophisticated cabling technology. It entails sending the probing equipment down into the oil well or other deep locations as desired with the help of cables. By sending such equipment down, many things which are not possible for human beings to do in person, can be done thanks to the equipment. The electrical cable or the wireline sent below constantly sends information up, which is interpreted with the help of software.

Wireline is used in different stages in the oil industry. For example in oil exploration, it becomes necessary to send sophisticated electrical equipment down, and collect soil readings. Based on the soil readings it is possible to analyze how much further it would be necessary to drill so as to reach the oil. Once the oil has been located, there are many other functions for which wireline technology is used such as –

  • Reservoir monitoring
  • Production logging
  • Well perforation
  • Well maintenance and repairs
  • Coil tubing
  • Tubing of drill pipe
  • Recovery of pipe
  • Cleaning of well
  • Setting plugs

Both out of casing and inside casing wireline services are used by the oil and gas industry.

Oil may be found at sea or on land, but it is always underground. Oil needs to be extracted and stored as well. The storage of oil is another function for which wireline services may be needed. This is because crude oil requires underground salt mines to be stored. Wireline services are needed to keep salt out of such oil storing chambers, caverns, or wells, as the case may be. Therefore, wireline services indicate whether the salt from the surroundings is moving into the cavern. Such storage is a complex process as there is always the possibility of the storage room collapsing.

Wireline services are also used for storing hydrocarbons, which are again stored underground. These services differ slightly because it is necessary to design and construct such underground storage tanks. Then again, the question of operation and logging needs to be done, for which wireline services are needed. Any decommissioning or abandoning also needs to be done without letting the ground sink. Other factors, such as pollution and water contamination, also need to be considered while managing such storage facilities. Therefore, wireline services play a crucial role in the engineering activity associated with hydrocarbon storage, and its transportation.

Geologists responsible for locating oil, and the engineers responsible for its extraction and storage, require wireline services for maintenance too. The rapid depletion of the stored hydrocarbons or oil needs to be avoided many times as the balance in pressure internally and externally needs to be maintained. Pressure from the surroundings can affect the storage of oil well. Based on the extrapolation and analysis of data received from remote locations deep inside earth, engineers decide how much casing is needed and the risks in setting up oil or hydrocarbon storage facilities in the selected location. Such assessment also enables these professionals to establish the necessary controls and management systems, apart from setting up the required procedures, plans, and drills for emergencies, if any. Effectively, wireline services combine electrical and electronic tools to collect information from remote and inaccessible locations, so that it is possible to come up with oil extraction and storage strategies.
