Today, there is considerable emphasis being placed on learning from near-miss incidents and applying additional safeguards which would minimize possibility of escalating adverse impact of these events in the future. Not all near-miss incidents have potential for major adverse impact. It is important to focus on near-miss incidents which could result into incidents with major adverse impact. This paper applies a modified "Risk Assessment Matrix," that is commonly used for conducting PHA assessments such as HAZID and HAZOP, to estimate potential future risk indication conveyed by near-misses. In a strategic sense, near-miss management spans all work systems of an organization and its culture: IT system, operations, legal, and many others. Source

SCADA is a pivotal tool in achieving impressive productivity and reliability of pipelines. However, SCADA systems face cyber threats that could render them inoperable, causing substantial adverse effects on profitability. A discussion covers SCADA cyber threats and possible solutions from the viewpoint of management; managerial level, and details of intricate technical nature, e.g., SCADA programming, firewall protocols and intrusion detection system protocols are omitted.

Safety assessment of pipeline projects involves coordination with a large number of groups, often spread over diverse geographical regions. Managers will have an opportunity, as well as a challenge, to communicate to a wide spectrum of personnel. Establishing a good rapport at an early stage of the safety assessment process is essential. Having a strategic understanding of local issues and the safety impacts is the key to pipeline safety assessments. A discussion covers getting vital risk assessment information; health, safety, security and environmental management systems; and the cyber security of pipeline controls and SCADA systems. Source

Regulatory mandates for the stringent control of air quality, including greenhouse gas emissions, are being increasingly tightened in the US. Agencies at the federal, state and local levels are requiring more data collected by direct measurement from continuous emissions monitoring system (CEMS) equipment instead of relying on factors to calculate emissions based on other process measurements. These directives require more stringent auditability requirements and transparency of emission calculations. Request for comprehensive data are technology advances that continue to provide instruments with the measurement capability to collect larger, more massive datasets are being made to complement this objective. The goal of air emissions data collection is to generate accurate and consistent environmental reports as part of a larger enterprise information management strategy. Source

Threshold chloride levels for localized corrosion of carbon steel material have been studied in three types of simulated concrete pore solutions: sodium hydroxide-potassium hydroxide (NaOH-KOH) with pH 11.6, calcium hydroxide (Ca[OH]2) with pH 12.6, and sodium hydroxide-potassium hydroxide-calcium hydroxide (NaOH-KOH-Ca[OH]2) with pH 13.3. The nonuniform corrosion rates of carbon steel were measured with coupled multielectrode array sensors (CMAS) when the chloride concentration was changed from 0.0005 mol/L to 1 mol/L in each solution. Open-circuit potentials were also measured from the coupling joint of the CMAS probes and electrodes made of rebar specimens immersed in the simulated pore solutions to verify the results from the CMAS probes. © 2014, NACE International.
