Commissioning Management

The main objective of commissioning is to effect 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.
Commissioning management ensures that all systems and components in a industrial plant is designed, installed, tested, operated and maintained according customer operational requirements and specifications. This not only applies to new projects but also to existing units and systems subject to expansion, renovation or revamping. The commissioning process comprising planning, execution, and control of hundreds of thousands of inspection and test activities on ìcommissionable objectsî, such as instruments, equipments, skids, modules, circuits, loops, 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, including sometimes an assisted operation phase.
Extensive and intensive experience in the industry enables Tumaco Services to provide this service. The broad technical detail knowledge and large commercial picture makes Tumaco Services the perfect partner in delivering a excellent result to your 'internal' and 'external' customers.

Commissioning Assistance

In practice, the commissioning process comprises 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 more complex objects such as modules, subsystems and systems. Thorough and extensive field service experience allows Tumaco Services to review operation manuals, instructions for plant start-up, shutdowns and handling various emergencies, guidelines and supervision for pre-commissioning activities, plant turnarounds and maintenance, and plant start-up supervision guaranteeing a smooth and flawless startup of new or retrofitted rotating machinery.

Field Service Assistance

Once commissioned and handed over plant operation mostly continues to full customer satisfaction. Unfortunately it is only a matter of time that the plant throughput is off design conditions, sometimes related to the rotating equipment problems. Maybe related to mechanical conditions, but is more often related to failures in field instrumentation and control systems. At these instances it is sometimes difficult to execute the trouble shooting exersize in an attempt to pinpoint the problem area. Rapid response time, hands on experience and to the point troubleshooting approach in emergency situation makes Tumaco Services the perfect partner assisting you to pinpoint these problem areas in a timely fashion in an attempt to minimize production losses or excessive flaring.

Project Management

Having a defined beginning and end every project is a temporary endeavor, usually constrained by multiple variables. The temporary nature of projects stands in contrast to business as usual (or operations), which are repetitive, permanent or semi-permanent functional work to produce products or services. In practice, the management of these two systems is often found to be quite different, and as such requires the development of distinct technical skills and the adoption of separate management. The primary challenge of project management is to achieve all of the project goals and objectives while honoring the project constraints. The secondaryóand more ambitiousóchallenge is to optimize the allocation and integration of inputs necessary to meet pre-defined objectives.

Project managers have the responsibility of the planning, execution, and closing of your project and as such are accountable for accomplishing the pre-defined project objectives. Key project management responsibilities include creating clear and attainable project objectives, building the project requirements, and managing the constraints like cost, time, and scope. The project manager is often a customer representative and has to determine and implement the exact needs of the customer, based on knowledge of the firm they are representing. The ability to adapt to the various internal procedures of the contracting party, and to form close links with the nominated representatives, is essential in ensuring that the key issues of cost, time, quality and above all, customer satisfaction, can be realized. International project management experience with major players in the Oil & Gas industry enables Tumaco Services to bring a project to successful completion to full customer satisfaction.

Project- and Control System Engineering

Project engineering is an interdisciplinary field of engineering that focuses on how complex engineering projects should be designed and managed. The coordination between different disciplines, and automatic control of machinery become more difficult when dealing with large, complex projects. Project engineers deal with work-processes and tools to handle such projects, and it overlaps with both technical and human-centered disciplines such as control system engineering and project management.

Control systems engineering applies control theory to design systems with predictable behaviors. Sensors are used to measure the output performance of the rotating equipment and those measurements can be used to give feedback, allowing corrections to be made toward desired performance. Multi-disciplinary in nature, control systems engineering activities focus on implementation of control systems. Control systems engineering focuses on the modeling of a diverse range of dynamic systems (e.g. mechanical systems) and the design of controllers that will cause these systems to behave in the desired manner. Although such controllers need not be electrical many are and as such control engineering is often viewed as a subfield of electrical engineering. Having said this the focus is often shifting back to the mechanical engineering discipline, as intimate knowledge of the dynamic system being controlled is often desired.

Electrical circuits, digital signal processors and microcontrollers can all be used to implement Control systems. Control system engineers often utilize feedback when designing control systems. Where there is regular feedback, control theory can be used to determine how the system responds to such feedback. In practically all such systems stability is important and control theory can help ensure stability is achieved. Detailed control system engineering experience allows Tumaco Services to review or even assist in existing and new control system designs. During such effort design flaws and improvement areas are deployed in attempt to tailor the control system design to your needs and requirements.

Factory- and Site Acceptance Testing

Acceptance testing is black-box testing performed on a system (control systems, compressor, gas turbines, steam turbines, etc) prior to its delivery. Acceptance testing by the system provider is often distinguished from acceptance testing by the customer prior to accepting transfer of ownership. In such environments, acceptance testing performed by the customer is known as user acceptance testing (UAT). This is also known as end-user testing, site (acceptance) testing, or field (acceptance) testing.

Acceptance testing generally involves running a series of tests on the completed system. Each individual test, known as a case, exercises a particular operating condition of the customer's environment or feature of the system, and will result in a pass or failure outcome. The test environment is usually designed to be identical, or as close as possible, to the anticipated user's environment, including extremes of such. These test cases must each be accompanied by test case input data or a formal description of the operational activities (or both) to be performed and a formal description of the expected results.

The series of tests is run against the supplied input data or using an acceptance test script to direct the testers. Then the results obtained are compared with the expected results. If there is a correct match for every case, the test serie is said to pass. If not, the system may either be rejected or accepted on conditions previously agreed between the customer and the manufacturer.The objective is to provide confidence that the delivered system meets the business requirements of customer and system provider. The acceptance phase may also act as the final quality gateway, where any quality defects not previously detected may be uncovered. A principal purpose of acceptance testing is that, once completed successfully, and provided certain additional (contractually agreed) acceptance criteria are met, the customer will then sign off on the system as satisfying the contract (previously agreed between customer and system provider), and deliver final payment.

In depth knowledge of the turbo machinery control industry standards makes Tumaco Services the ideal objective partner ensuring that factory- and/or site acceptance testing customer and system provider expectations are managed in a adequate and satisfactorily manner.
