Milazzo Refinery (RaM) has developed a new safety system to minimize the risks related to "hot works" (mainly explosion risks) during normal unit operations. The good practice was for the first time utilized during Fluid Catalytic Cracking pre-turnaround and turnaround phase from Milazzo Refinery. At that time, RaM implemented, for the first time, the integration between the existing network system of fixed hydrocarbon detectors with the welding machines through the Distributor Control System (DCS). This integration allowed to immediately switch off the power supply to the welding machines in case of detection of explosive atmosphere. Moreover, in order to cover as many welding points as possible, several mobile detectors were installed and integrated in the gas detectors system. The whole process is represented in the scheme in Figure 1.
We believe our prime responsibility is to protect the environment by utilizing the energy in a responsible way and also by reducing the wastage of energy. Energy conservation will play a vital role in climate change and leave our planet pristine for the next generations to come. In light of our Company's ambitious vision of reducing energy consumption and losses and to conserve energy without disturbing the regular business of the Company, we have started to evaluate all the options to conserve the energy by incorporating the latest technologies, conducting awareness programs and optimizing the energy consumption. In line with our objectives, we conducted a study on one of the existing office building to check all the possibility of reducing energy consumption without disturbing the regular activity. At the end, we realised that the simple and easy way to conserve Energy is through conducting an Energy Audit and implementing Energy Audit recommendations.
This document describes the journey taken over the years by the Milazzo Refinery, together with the Contractors, to achieve and maintain levels of excellence for the health and safety of all workers. The last step in this process was the "Safety Pact" between all parties involved in health and safety aspects. The Pact is updated and renewed every year with increasingly challenging objectives.
The Pact is based on the following innovative methods: STOP - ANALYZE - THINK - DO procedure. It is based on the self-evaluation risk which is a procedure that every employee has to follow before starting any activity Safety "Pills". Short meetings take place on the contractors working area aimed at analyzing good or and bad practice observed during the works execution Housekeeping Coordinator. New role dedicated to manage all the issues related with the housekeeping of the working areas Rewarding system to evaluate behaviours adopted in the working area: bonus/malus points to workers depending on their particular attention for safety.

Rewarding system to evaluate behaviours adopted in the working area: bonus/malus points to workers depending on their particular attention for safety.
The Safety Pact was thought and implemented as a first field test during a Major Turnaround (TA) and as a possible innovative tool to define rules and goals between RAM and Contractors, with the purpose of improving safety during turnaround activities and achieving the most important target of ZERO INJURIES. Following turnaround completion RaM and Contractors make a balance of the results analyzing performance index and making plan to improve weak area in the future.
The implementation of a formal signed Safety Pact between RaM dramatically increased engagement of different companies (client + contractors) towards safety and allowed RaM to achieve ZERO INJURIES during the Turnaround activities. Moreover it has been observed an improvement of the housekeeping, a reduction of non-compliances for dangerous behaviour and a widespread application of RaM procedure for scaffoldings.
The success of this kind of approach suggested RaM to adopt the safety pact to every refinery turnaround (both major and minor ones) but also extend it to each single refinery maintenance activity.
Over 70% of South Australia's demand today is supplied from renewable energy sources and is forecast to reach 100% by 2025, 7 years ahead of schedule. Large industries such as oil and gas have also transformed their vision to ensure utilization of renewable energy sources to provide a cost effective, clean and reliable day to day operations. This paper will therefore present a case study where renewable energy became the enabler for clean oil extraction and economic growth more broadly.
Renewable energy technologies have been at the forefront amongst South Australia's commercial and residential consumers. Large industries such as oil and gas have committed to green, clean methodologies to support their operations when extracting crude oil from wells. The use of solar and battery storage has presented an obvious solution given the proof and reliability of the technology to enable a reduction in carbon emissions and cost while extracting resources from deep wells. A pilot renewable energy off-grid project was successfully completed in South Australia and has proven successful which has now resulted in significant funding being allocated to convert an additional 56 sites.
The successful trial conducted in the State of South Australia allowed for oil pumps to be powered 100% using renewable energy which resulted in a reduction of CO2 emissions and operational costs incurred from the supply and transfer of fuel to the pumps. It is estimated that the adoption of renewable energy for oil extraction will result in an approximate saving of 140 barrels of oil per day which is currently used to fuel pumps and generators at these remote sites. Assuming an average price market of $50 (US) per barrel, this equates to $2.25m (US) per day with consideration to approximately 10% unavailability due to maintenance. The forecast saving of $2.25m (US) is intentionally calculated using market value to reinforce the potential additional revenue to be had from savings on oil consumption during the crude oil extraction process.
In addition to the above forecast savings, a further $70,000 (US) per annum could be saved purely from the use of diesel generators currently being used to supply pumps, this assumes the cost per generator is $190 (US) per day for operations excluding maintenance costs and associated overheads.
With the above in mind and the successful trials under way in Australia, there are a further 208 pumps which are currently in scope across the continent to be converted in an effort to reduce production costs, emissions and ensure a low maintenance operational strategy is in place as well as a low carbon strategy. (Australian Renewable Energy Agency (ARENA), 2019).
The financial savings above are forecast to increase with decreased requirements for high cost operational maintenance when compared to conventional sources being used to date in the oil industry.
When considering the financial viability of renewable energy solutions, in addition to the environmental and social benefits, it has been determined that for a single oil pump, the forecast payback period on investments made does not exceed 4 years.
Considering solar systems have a lifespan of 25 years, this means that the remaining operating of solar panels, that is in excess of 20 years will be solely revenue generating years. Taking also into account the 25 years of running for both systems, conventional vs. renewable energy, the forecast levelized cost of energy (LCOE) is $1.3 (US)/kWh vs. 14c (US)/kWh respectively.
This means over a 25-year period, with renewable energy it is forecast that the cost to maintain supply to oil pumps would be 10% of what it could be if conventional sources were used, notwithstanding the lack of electrical redundancy on site, associated maintenance costs and also the forecast reduction of carbon emissions per site.
By applying some of the analyses and key findings, it is necessary to see the oil and gas industries adopt renewable energy strategies to ensure low cost and reliable technologies for oil and gas productions and enable new opportunities for economic growth while ensuring continued commitment to address environmental and social challenges of tomorrow.
General Monitors' Gassonic Observer-H ultrasonic gas leak detector (Figure 1) is suitable for use in pressurized systems and is ATEX, IECEx, FM, and CSA hazardous area certified. It senses the airborne ultrasound emitted by gas leaking at high pressure. Since the detector responds to the source of a gas release rather than the dispersed gas, it is unaffected by changing wind directions, gas dilution, and the direction of the leak. Detection coverage varies from 13 to 20 m in radius in very low noise areas ( 58 dB), from 9 to 12 m in radius in low noise areas ( 68 dB), and from 5 to 8 m in radius in high noise areas ( 78 dB). The distances are defined for a methane gas leak of 0.1 kg/s.

Safety professionals periodically rely on the use of employee perception surveys to monitor and gauge safety performance in the workplace. When appropriately developed and assessed, these tools can provide invaluable information. Because of the proliferation in use of perception surveys over the years in the safety profession, this article will address the accepted practices of perception survey development, analysis and interpretation.
Use of Surveys in the Workplace by Safety Professionals
Surveys can play a vital role in safety program management. Perception surveys have been used to assess employee perceptions of the safety culture, safety climate, perceptions of the leading indicator effectiveness, incident risk perceptions and measurement of safety management system components. Surveys can also be a useful component of safety management systems. “Continuous improvement process as part of a safety management system relies on data collection” (Herrera, 2018). Surveys can play an integral part in this data collection. They can be used to determine employee needs and services that should be included as part of a wellness program (Rosen & Spaulding, 2009). Employee surveys are also a useful tool as part of a VPP program for obtaining opinion data pertaining to an organization’s safety culture (OSHA, 2008).
A literature review using the Science Direct search engine identified an increase in published research studies utilizing perception surveys from three published articles in 2000 to more than 30 in 2018. Most notably, perception surveys assessing safety culture and safety climate have accounted for a large number of the published research articles during this period.
