Before the commencement of full-scale operations, newly constructed pipelines are subjected to a series of checks which determine their suitability for their intended functions. These procedures include pipeline pre-commissioning and commissioning checks which are carried out one after the other. Pre-commissioning is primarily done to ensure that all pipeline construction was satisfactory and meets the standard safety specifications. Commissioning activities can only be carried out after pipelines have been duly pre-commissioned and determined to be safe for initial testing. Depending on the intended content a pipeline is meant to conduct, these pre-testing procedures may vary slightly. Oil and gas pipelines are designed to carry volatile and highly flammable contents over long distances. It is vitally important that these transport mechanisms are built to conform to the highest possible standards.
Engineering and construction companies generally follow a systematic procedure where by their startup engineers review the process design several times as it is developed; After the first review, a preliminary start-up and operations procedure is written; Decide what must be added to the design to make the process capable of being started up and operated; By the time the final engineering flow-sheets have been released a complete startup and operating instructions manual should have been completed. Utilities systems - steam, instrument air, process water, fire water, drainage, condensate return; Electrical systems; Instrumentation and instrumentation systems; Cleaning and flushing; Purging; Initial start up and shutdowns; Performance testing;. Mechanical equipment and machinery; Control Systems and Instrumentation; Operational testing; Proof testing and acceptance. These should define for the facility, each plant system: The order in which the systems will be started up; Individual activities at each stage; Operation testing requirements; Durations, waiting times, cooling times; Total duration for starting up each system; Resources required - labour, materials, equipment, services; Temperatures, pressures, fluid flows used. General commissioning engineers generally do not get involved in this in a hands-on manner.
Project commissioning is the process of assuring that all systems and components of a building or industrial plant are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client. A commissioning process may be applied not only to new projects but also to existing units and systems subject to expansion, renovation or revamping. In practice, the commissioning process is the integrated application of a set of engineering techniques and procedures to check, inspect and test every operational component of the project: from individual functions such as instruments and equipment up to complex amalgamations such as modules , subsystems and systems. Commissioning activities in the broader sense are applicable to all phases of the project from the basic and detailed design , procurement , construction and assembly until the final handover of the unit to the owner, sometimes including an assisted operation phase. The main objective of commissioning is to affect the safe and orderly handover of the unit from the constructor to the owner, guaranteeing its operability in terms of performance , reliability , safety and information traceability. Additionally, when executed in a planned and effective way, commissioning normally represents an essential factor for the fulfillment of schedule, costs, safety and quality requirements of the project. For complex projects, the large volume and complexity of commissioning data, together with the need to guarantee adequate information traceability, normally leads to the use of powerful IT tools, known as commissioning management systems , to allow effective planning and monitoring of the commissioning activities.
What are the things to be checked carefully during pre-commissioning or commissioning activities for instrument engineer? Before a plant or facility is handed over for normal operation, it should be inspected, checked, cleaned, flushed, verified and tested.
The purpose of the meeting was to introduce Rev1 to Dangote Oil Refining Company and for Rev1 to express interest in supplying technology, people and services for the systems completion, pre-commissioning, commissioning, start-up of the Dangote Refinery. Following the presentation, Mr Shukla requested further information on how Rev1 could execute the required workscope. This document contains the execution strategy Rev1 would adopt to deliver the activities leading up to a safe and productive start-up of the refinery. Communication lines, meetings and reports established to ensure real-time management of the Commissioning Phase. Owner Operator are addressed during the project lifecycle thus validating the Operability and maintainability and overall viability of the asset is achieved.
Спокойно. Он оглядел пустой зал. Ни души. Продала кольцо и улетела. Он увидел уборщика и подошел к .
- В Альфонсо Тринадцатом строгие правила охраны приватности постояльцев.
- Ему не стоило напоминать о поразительной способности Мидж Милкен предчувствовать беду. - Мидж, - взмолился он, - я знаю, что ты терпеть не можешь Стратмора, но… - Это не имеет никакого значения! - вспылила. - Первым делом нам нужно убедиться, что Стратмор действительно обошел систему Сквозь строй. А потом мы позвоним директору. - Замечательно.
Северная Дакота, - прошептала она еле слышно. - Посмотрим, кто ты. Сьюзан прочитала открывшееся сообщение, которое состояло из одной строчки, потом прочитала его еще .
Оба противника оказались на полу. Беккеру удалось оторваться от убийцы, и он рванулся к двери. Халохот шарил по полу, нащупывая пистолет.
