Maintenance inventory

A few computerized PLM schemes are dynamic systems and can be integrated into an overall maintenance management information system. These contain maintenance inventory and purchase order modules and go far beyond just another work order system . They provide the necessary information to control complex maintenance environments, thereby improving productivity and reducing operational costs.

Under an annually renewed, systemwide contract with WGI, Rockwell Automation works with all of the incineration sites through surveys and visits to forecast requirements for control system spares (based on historical and forecast spares depletion rates), establish certified spares inventory levels for each site, repair or rebuild failed parts and components, and to special-build new parts and circuit cards as needed to keep maintenance inventories at a safe operational level. The Rockwell Automation support group, located in Cleveland, Ohio, also implemented a relatively simple soft-... 

Maintenance inventory The proper quantity of the proper spare parts wfll be on hand due to progressive MRO procurement and internal storeroom controls, aU to support maintenance excellence. 

The implementation of CMMS and EAM will include an inventory system that totally supports the requirements of maintenance and the storeroom. Maintenance inventory wfll be managed to ensure that the right part is available at the right time without excessive inventory levels. Information from aU available sources will be used to determine optimum stock levels. A continuous review of stock levels will be made to eliminate excess inventory and obsolete parts. Inventory reductions will be achieved through more partnerships with suppliers and vendors that establish joint commitments to purchase based on responsive service and fast delivery. Positions within MRO material management and procurement wfll increase in their importance and level of technical knowledge to perform effectively... 

Economy of time and resources dictate using the smallest sized faciHty possible to assure that projected larger scale performance is within tolerable levels of risk and uncertainty. Minimum sizes of such laboratory and pilot units often are set by operabiHty factors not directly involving internal reactor features. These include feed and product transfer line diameters, inventory control in feed and product separation systems, and preheat and temperature maintenance requirements. Most of these extraneous factors favor large units. Large industrial plants can be operated with high service factors for years, whereas it is not unusual for pilot units to operate at sustained conditions for only days or even hours.

Adequate support from the facility staff is absolutely essential. The facility staff must help the analysis team gather pertinent documents (e.g., PSilDs, procedures, software descriptions, material inventories, meteorological data, population data) and must describe current operating and maintenance practices. The facility staff must then critique the logic model(s) and calculation(s) to ensure that the assumptions are correct and that the results seem reasonable. The facility staff should also be involved in developing any recommendations to reduce risk so they will fully understand the rationale behind all proposed improvements and can help ensure that the proposed improvements are feasible. Table 12 summarizes the types of facility resources and personnel needed for a typical QRA. 

Operation includes nonual start-up, normal and emergency shutdown, and most activities performed by die production team. Whilst inlierently safe plant design limits inventories of hazardous substances, inherently safe operation ensures die number of individuals at risk are minimized. Access to die plant for non-essendal operational people such as maintenance engineers, post staff, administrators, quality control samplers, warehouse staff delivering raw material or plant items or collecting finished product, members of security, visitors etc., must be controlled.

Even, limited PSAs use and contain much information. This information may come as memos and process reports and flow sheets, equipment layout, system descriptions, toxic inventory, hazardous chemical reactions, test, maintenance and operating descriptions. From this, data and analyses are prepared regarding release quantities, doses, equipment reliability, probability of exposure, and the risk to workers, public, and environment. An executive summary analysis is detailed, and recommendations made for risk reduction. Thus the information will be text, calculations of envelope fracture stresses, temperatures, fire propagation, air dispersion, doses, and failure probabilities - primarily in tabular form. 

An effective maintenance system depends upon it being adequately resourced. Maintenance resources include people with appropriate skills, replacement parts and materials, access to support from OEMs when needed, and the funds to purchase this material. If the equipment is no longer supported by the OEM, then you may need to cannibalize old machines or manufacture the parts yourself. This can be a problem since you may not have a new part from which to take measurements. At some point you need to decide whether it is more economical to maintain the old equipment than to buy new. Your inventory control system needs to account for equipment spares and to adjust spares holding based on usage. 

This report addresses ammonia plant shutdowns over the listed time period in 40 countries. It provides a basis for comparing plant performance area by area leading to better control of reliability efforts while reducing maintenance and unplanned shutdown costs. Data are presented for shutdowns due to power, equipment, instrumentation, feedstock and product inventory control. 

Various forms have been developed to collect plant data. Figures 6.1 and 6.2 are generic forms published in EuReDatA Project No. 3. The Specimen Inventory form, Figure 6.1, is designed to collect data needed to establish the equipment description and total equipment population. Many maintenance systems offer some of these data, but usually not in a useful format or to the extent desired. The Specimen Event or Failure Report form, Figure 6.2, is used to capture failure event data that, when summed, will allow determination of the failure rate numerator—the number of failures within a unique plant population. 

What details must be sought from the suppliers of both hardware and software packages How can the computer best meet the department s current requirements and how can it be added to if and when necessary (e.g. increased demand from planned maintenance) How can it be extended to cover other departments (network) Energy consumption input from condition monitoring, stores inventory, project work and possible interaction with space allocation must also be considered. 

A survey of 500 plants that have implemented predictive maintenance methods indicates substantial improvements in reliability, availability and operating costs. The successful programs included in the survey include a cross-section of industries and provide an overview of the types of improvements that can be expected. Based on the survey results, major improvements can be achieved in maintenance costs, unscheduled machine failures, repair downtime, spare parts inventory, and both direct and in-direct overtime premiums. In addition, the survey indicated a dramatic improvement in machine life, production, operator safety, product quality and overall profitability. 

In addition, detailed analysis of the chemical and physical properties of different oils used in the plant can, in some cases, allow consolidation or reduction of the number and types of lubricates required to maintain plant equipment. Elimination of unnecessary duplication can reduce required inventory levels and therefore maintenance costs. 

As a minimum, your baseline data set should include the labor, overhead, overtime premiums and other payroll costs of the maintenance department. It should also include all maintenance related contract services, excluding janitorial, and the total costs of spare parts inventories. The baseline should also include the percentage of unscheduled maintenance repairs versus scheduled actual repair costs on critical plant equipment and the annual availability of the plant. 

In this chapter, we focus on strategies, tools and metrics that help chemical choosers to green their chemical product inventories and to benchmark progress. The term chemical chooser applies to those who purchase chemicals for use in the development of formulated products or those who purchase formulated chemical products for use in their use in activities such as maintenance, repair and operations. Most product manufacturers are chemical and material choosers in contrast to chemical or raw material manufacturers who process, synthesize and supply chemicals as raw materials. 

An organized document filing system must be maintained. This could be a paper file, an electronic document file, or a mixture of both. The equipment inventory system contains key information on the components of each system, their performance criteria and maintenance and calibration status. All documents including installation and performance documentation, as with other documents necessary to demonstrate the quality of the data, include SOPs for the qualification procedures, calibration, maintenance, personnel training, etc. If the manufacturer s operating, service, or maintenance manuals are used or cited in the operating procedures, copies of these manuals should be maintained. To facilitate retrieval, documentation should be stored in a central location and be indexed for easy retrieval.
