We have engineered and managed numerous projects around the world in which our engineers have joined the owner’s team at the front end to define the pre-commissioning scope, responsibility matrix, and to develop procedures and packages for field execution. The aforementioned service can be extended to a construction contractor either in the bid phase or construction phase. Our engineers can work with your planners to gain a better understanding of a project’s scope and to help improve scheduling.
FourQuest Energy’s engineers draw on experience from startup, shutdown, and maintenance projects around the world. With this knowledge, we are able to recommend practical and effective solutions to every situation we are presented with.
On day-to-day plant work, startup, and shutdown work, our engineers review the job specifications and criteria with site personnel. They are also able to assist owners and constructors with onsite technical support for startup operations, commissioning supervision, and technical reviews, determining the best method and route for the job execution.
FourQuest Energy uses technical knowledge coupled with field experience to custom tailor our recommendations and procedures to our clients’ systems. We aim to engineer and determine all parameters, conditions and factors before the commencements of any operation.
FourQuest’s calculations, results, and recommendations are based on solid scientific and engineering principles. Procedures are written to our clients’ specifications and any other standards or regulations governing the project. Our experienced and knowledgeable field staff ensures that all services are executed following the recommendations and procedures, and our engineers produce complete procedures detailing the technical aspects of the job to be executed in the field. The procedures also address safety and environmental concerns, and usually provide a risk assessment matrix detailing potential hazards and solutions for risk mitigation.
FourQuest Energy has extensive experience creating and executing pipe cleaning procedures. We have spent many years developing our pipe cleaning procedures, making changes and improvements every step of the way. Today, we have industry leading procedures for the safe and efficient cleaning of process piping systems. All our procedures include step by step instructions, digitally marked up drawings, and velocity and cleaning force ratio calculations. They are engineered to be effective, yielding the highest level of cleaning possible for each specific piping system. In addition to client requirements, FourQuest Energy can also make recommendations as to industry standard practices for specific piping systems and their commodities.
The creation of hydrotest packages is an important service that FourQuest Energy can both perform and facilitate. We can also combine our experience of pipe cleaning programs with the design of hydrotest packages to allow for efficient cleaning after testing is complete. For example, by designating cleaning packages that are of similar scope to potential cleaning packages, downtime in the field can be avoided waiting for a section of piping to be completed through another hydrotest. FourQuest uses electronic markup programs for all procedures and packages. Marking drawings electronically allows for clean packages, which can be easily edited as required. It also allows the piping and instrumentation diagrams to be labeled to show the system to be tested along with all isolation points, removed equipment, drains, and vents.
La définition pratique de la portée des systèmes de tuyauterie est importante tout au long de la construction, du démarrage et de l'exploitation des installations. Du point de vue d'un prestataire de services de nettoyage, des systèmes de tuyauterie dont la portée est définie de manière efficace constituent un élément clé pour des prestations de nettoyage efficaces. La définition de la portée des systèmes afin de permettre la rotation par produit facilite l'exécution sur le terrain du nettoyage de mise en service. Par exemple, lorsque les systèmes sont dimensionnés pour inclure plusieurs produits ou comportent de courtes sections de tuyauterie, il est difficile de créer des programmes de nettoyage efficaces. Ce problème est amplifié lorsque les systèmes ne sont pas remis pour nettoyage dans l'ordre prévu. Le nettoyage d'un grand système peut être retardé si une section de la tuyauterie appartient à un autre système. FourQuest peut aider le client à définir la portée des systèmes, ce qui sera non seulement bénéfique pour la remise finale de la construction, mais permettra également de gagner un temps considérable lors de l'élaboration et de l'exécution des procédures. En plus d'être en mesure d'évaluer les systèmes de tuyauterie pour définir leur portée, FourQuest peut fournir une expertise en matière de définition de la portée des systèmes électriques et d'instrumentation, ce qui permet d'obtenir un ensemble complet de définition de la portée des systèmes.
There are two elements of system reinstatement that can potentially save time during a commissioning cleaning work scope. The first is efficient planning and allocation of resources with regards to the cleaning scope. Cleaning procedures that have been written to aid in system preparation and reinstatement can save a significant amount of both time and labour. The second factor arises during the execution of field work; effective management of labour and equipment resources during commissioning cleaning can yield the greatest savings. We have a history of working closely with the on-site contractors to provide timely system reinstatement. Typically, we will be involved in a system as soon as it is turned over for cleaning. We will have direct contact with the foremen and crews removing and setting up the system to be cleaned. When the time comes to reinstate a system, we’re familiar with all points in the system that require field work to restore it to P&ID design state. The reinstatement of systems can be monitored and tracked using the original cleaning procedure packages.
In order to maintain system quality throughout piping systems, it is important to have baseline thickness measurements of the pipe walls. Ultrasonic testing provides a fast, economical solution to measuring wall thickness. Ideally, baseline UT readings are taken before welding to minimize repeat work should a section of pipe fail to meet minimum thickness. It is critical that heat numbers and spool numbers, as well as the location of the testing, be diligently recorded when this work is performed. This ensures 100% traceability in the future. Baseline thickness measurements are performed on certain line classes as denoted by the owner’s standard.
