A quantitative way for determining the Safety Integrity Level of Safety Instrumented System (SIS) on Offshore Metering and Custody Transfer Facility in Campeche Bay Mexico is presented in this work. The methodology that was employed in order to assess and determine the Reliability parameters of SIS; which was carried out in three steps: 1. Identify undesirable events that can damage to personnel using the API-14C and to, the facility and the environment (by oil spill in hoses when the oil tanker is filled), 2. Estimate the severity and consequences of risk, using safety layer matrix of ISA S84.01 and, 3. Quantify the severity of each risk identified with the fault tree analysis. This last step uses the minimal cut sets, an innovative concept in petroleum industry, this provides valuable information about possible combinations of fault events, that can result in a critical failure of the system. The period of maintenance of the main SIS components (sensors, logic solver and final element), was reduced applying redundancy in the primary element. Furthermore, the results obtained of this analysis can be used by insurance companies or institutions that certify under standards of process quality and safety.

This paper presents a theoretical solution for transient heat conduction in a rod of finite length with variable thermal properties. A numerical procedure is developed and the results of one example are presented and compared with the corresponding solution for the case of constant properties. Application to the problem of determination of thermophysical properties is discussed briefly.

Proper recording of thermophysical properties for molten salts (MSs) and molten salts based nanofluids (MSBNs) is of paramount importance for the thermal energy storage (TES) technology at concentrated solar power (CSP) plants. However, it is recognized by scientific and industrial communities to be non-trivial, because of molten salts creeping (scaling) inside a measuring crucible or a sample container. Here two strategies are proposed to solve the creeping problem of MSs and MSBNs for the benefit of such techniques as differential scanning calorimetry (DSC) and laser flash apparatus (LFA). The first strategy is the use of crucibles with rough inner surface. It was found that only nanoscale roughness solves the creeping problem, while micron-scale roughness does not affect the wetting phenomena considerably. The second strategy is the use of crucible made of or coated with a low-surface energy material. Both strategies resulted in contact angle of molten salt higher than 90° and as a result, repeatable measurements in correspondence to the literature data. The proposed methods can be used for other characterization techniques where the creeping of molten salts brings the uncertainty or/and unrepeatability of the measurements.
