Supervision and monitoring

According to Ref. 32, the functioning of impressed current cathodic protection stations should be monitored every 2 months, and the stray current protection station every 1 month. If protection installations are provided with measuring instruments for current and potential, this supervision can be carried out by operating staff, so that the readings are recorded and sent to the technical department for 

A check on the cathodic protection of the pipeline should be carried out annually according to Section 10.4, where, of course, only the on potential should be measured. This value should also be compared with the values of the measurements in Section 10.4. If there are no changes in the on potentials and the protection current densities for the individual sections of the pipeline, it can be concluded that the off potential has not changed. The values can easily be compared using computers and represented in plots. If the protection current and potential distribution have changed, or in any case every 3 years, the off potentials as well as the on potentials should be measured. 

The cathodic protection of pipelines is best monitored by an intensive measurement technique according to Section 3.7, by an off potential survey every 3 years and by remote monitoring of pipe/soil potentials. After installation of parallel pipelines, it can be ascertained by intensive measurements whether new damage of the pipe coating has occurred. These measurements provide evidence of possible external actions that can cause mechanical damage.

Eailure of sensor critical to monitoring and supervision of the process. The critical sensor may vary from process to process or stage to stage in the same vessel. 

Some questions could arise concerning process control and especially concerning the problem of deviation detection. Solutions can be found by using software able to monitor and supervise the process in order to guarantee production quahty and safety of the plant and operators [38]. 

The contractor doing the engineering work requires a certain degree of monitoring and supervision and, in some cases, even direction from the Owner. This is especially true when the contractor performs its work under a cost reimbursable contract. 

In this case buprenorphine precipitated opioid withdrawal symptoms after heroin use. This highlights the importance of regular monitoring and supervision of community-dispensed buprenorphine. 

Nowadays, for reasons of safety and performance, monitoring and supervision have an important role in process control. The complexity and the size of industrial systems induce an increasing number of process variables and make difficult the work of operators. In this context, a computer aided decision-making tool seems to be wise. Nevertheless the implementation of fault detection and diagnosis for stochastic system remains a challenging task. Various methods have been proposed in different industrial contexts (Venkatasubramanian et al., 2003). 

Preaction Unit tactically disperses in concealed marshalling area. Makes contact with control point for final orders. Control point monitors and supervises rate of movement into ianes to prevent congestion. Watch One soldier from the battalion decon crew. Every three minutes two vehicles will be released from the marshalling area. On signal vehicles will proceed to the decon station in their respective lane. ]... 

The structural engineer who is the principal of the firm has a derivative ethical responsibility to monitor and supervise her/his subordinate employees in a substantive way. The head structural engineer must not turn over responsibility for a particular project to a subordinate structural engineer and then cease to monitor, supervise, and check her/his work. In particular, the head structural engineer cannot ethically allow her/his personal seal of approval to be used by the subordinate without checking on the accuracy and reliability of the work that s/he has done on a project. 

Table 0.1 provides a more comprehensive scheme of methods of corroaon control, in which it has been considered appropriate to include Corrosion Testing and Monitoring and Supervision and Inspection , since, as will be discussed subsequently, these can be of some importance in ensuring that the material, coating or procedure provides effective protection. No attempt has been made to include environments for the very good reason that a particular...

As indicated earlier, in a modem refinery a consolidated control room approach and central monitoring of equipment and process is preferred. For proper implementation of this, in some cases a supervisory DCS is used and is placed at a highet level than the process control DCS. The main function of this supetvisoty DCS is to effectively carry out the coordination between various DCS units and assist central monitoting of equipment and process. The major advantages associated with such centralized monitoring and supervision shall include ...
