Operating repair costs

The cost and economics of cathodic protection depend on a variety of parameters so that general statements on costs are not really possible. In particular, the protection current requirement and the specific electrical resistance of the electrolyte in the surroundings of the object to be protected and the anodes can vary considerably and thus affect the costs. Usually electrochemical protection is particularly economical if the structure can be ensured a long service life, maintained in continuous operation, and if repair costs are very high. As a rough estimate, the installation costs of cathodic protection of uncoated metal structures are about 1 to 2% of the construction costs of the structure, and are 0.1 to 0.2% for coated surfaces. 

Operating costs, in contrast, are more straightforward to determine because they depend on system efficiency, which, in turn, is related to voltage and current density (the current generated per unit area of electrolyte). Fuel savings are expected since the fuel cell operates more efficiently than a heat engine, and there may be lower maintenance and repair costs because fuel cells have fewer moving parts to wear out.

In the first years of operation, operating persoimel are required to a level of 75 h/day, seven days per week for monitoring (note that chemical and radionuclide analyses are not included in this costing), visual inspection and minor repair works. These expenses will be reduced over time when more statistical data become available from the wetland operation. Labour costs are estimated at about 30/h. 

Control rooms serving more than one process unit do not present unique hazards when considering the proper location of the building. However, they can significantly increase the size of a loss because of their multiple uses. For example, an incident in one unit could damage the central control room and impact the ability to operate other units. The business interruption financial impact is likely to far outweigh the actual damage repair costs. 

Including the 4,000 operating costs, the model plant would thus realize 204,350 profit the first year, and 308,600 each year thereafter, neglecting tax incentives and maintenance/repair costs on the added equipment. 

For operating rates less than plant capacity, the maintenance and repair cost is generally estimated as 85 percent of that at 100 percent capacity for a 75 percent operating rate, and 75 percent of that at 100 percent capacity for a 50 percent operating rate. 

Thus, if in 1970 we have a 1962 model plant overhauled in 1968, it doesn t matter whether we continue operating or build a new plant, for in both events we will realize the maximum return of 80. However, it is clearly not advantageous to repair such a plant, since the return after repair costs would only be 55. Notice that by this simple analysis of one possibility at the last stage we have eliminated four policies from consideration, namely BCCRR, BCRRR, BRCRR, and BRRRR. If in addi-... 

Maintenance and repair costs (M R) are a deductible corporate expense against taxable income. Using appropriate tax terminology on all M R work orders will save your company money. The costs associated with Capital Expenditures (capital) and Service to Operations are not deductible. Key words used in computerized materials management databases should help clarify these categories and should be used for effective cost savings. See Figure 2-15.

These costs can only be approximated for the total lifetime of the equipment, as they vary greatly according to the quality of the equipment and the qualification of the operator. To allow for the fact that the more heavily the equipment is used the more likely it is to require repair, a repair cost of 1.00 DM per measurement is included in the calculation. 

Effective preventive/predictive maintenance programs will be used to anticipate and predict maintenance problems in order to eliminate the uncertainty of expected breakdowns and high repair costs. Predictive maintenance wiU not be limited solely to the detection of failure but will proactively identify and eliminate the root causes of chronic problems. Preventive/ predictive maintenance programs will be adequately staffed to cover adl major assets within the operation. Maintenance wiU maintain current techniceil knowledge and experience for applying a combination of predictive technologies that is best suited for the specific application or system. 

Uhlig s study (7) attempted to measure the costs of corroding structures to both the owner/operator (direct cost) and to others (indirect costs). The total cost of corrosion to owner/operators was estimated by summing the cost estimates for corrosion prevention products and services used in the entire US economy such as coatings, inhibitors, corrosion-resistant metals, and cathodic protection and multiplied these totals by their respective prices. Domestic water heater replacement, automobile internal combustion engine repairs, and replacement of automobile mufflers were selected as examples to estimate the cost to private consumers/users. Adding both the direct and indirect costs, the annual cost of corrosion to the United States was estimated to be 5.5 billion or 2.1% of the 1949 GNR This method was used in Japan and estimated the cost of corrosion at 9.2 billion equivalent to 1-2% of the Japanese GNR. 

Life cycle costing (LCC) is a concept for estimating the total cost or total ownership cost (TOC) which includes acquisition costs (total capital cost, i.e., land acquisition costs and construction costs), ownership costs (all future costs, viz., installation costs, operation costs, repair costs, service and maintenance costs, and disposal costs), as well as other cost components. 

Expenses for critical infrastmcture are not only costs for its design and building but they also include costs for its operation, maintenance, repair and modernisation. Therefore, the risks connected with each infrastmcture must also include the risks from just given domains and the region management must know how to deal with them. It is necessary to asses the risks from disasters that can be denoted as financial market failure because with them it is connected failure of finances for maintenance, operation, repair and modernisation of objects of critical infrastrucmre. It is caused by the fact that critical infrastrucmre criticality increases if not good maintenance and good repair are performed (which cause the vulnerability increases). 

The life cycle cost of an item of equipment includes all the costs associated with the equipment over its entire lifetime. The main costs typically comprise the initial acquisition, installation and commissioning costs, energy, operation, maintenance and repair costs, environmental costs, and decommissioning and disposal costs. In this paper the LCC is simplified to only the initial purchase cost and energy cost. This assumption is vahd if as in this case same supplier and similar equipment s are compared, then the installation cost, maintenance etc. can be assumed to be the same.

Once the loan is paid off, after the 30-year period, for the remainder of the plant lifetime there will be no payments to the bank. During those latter years of operation, the only costs that the plant operator will incur will be normal operating costs, including the cost of fuel. Many of the 104 operating nuclear power plants in the United States now are in this situation, being free of the burden of the amortization costs. However, major maintenance and repair costs, such as steam generator replacements, may also be amortized, adding capital costs later in the plant life. 

A clean driUing room decreases repair costs and the possibility of improper operation of the drilling machines. Wipe surfaces clean using a lint-free cloth or use a vacuum to remove debris. 

Preventive maintenance provides more operational rehabihty however, it also involves higher inspection and maintenance costs, if the inspection strategy is appHed, or higher repair costs if the exchange strategy is applied. Which maintenance strategy will be applied depends on a number of factors, such as Hfespan, personnel structure etc, and will be determined by company management... 

This is a system whereby the repair control centre and key personnel report property damage situations. The system should be simple, designed to operate with a minimum amount of written reporting, and flexible since repair cost accounting methods may vary from workplace to workplace. 

ABSTRACT Offshore wind farms are very expensive assets, not only to design and build, but also to operate and maintain. Their remote location, coupled with weather s constraints and harsh marine environment, and the lack of adapted access equipment, make their maintenance complicated and expensive due to high repair costs, high transportations costs and painful production losses due to high downtime.
