Abstract Light, sweet crude oils are depleting, forcing oil and gas companies to explore and operate in increasingly deeper waters, remote geographical locations, and harsher environmental conditions with higher safety risks. This paper analyzed the common misuse and errors of typical quantitative risk assessments (QRAs) during identification, assessment, approval, and project implementation stages of a project for the case of optimization of facilities and manning fixed offshore oil and gas platform, as well as the scenario of a gas leak from riser pipeline of a floating production platform. The lessons learned were then applied to design an optimized QRA process for a real case, preproject assessment for a proposed addition of a riser platform (R-A) to a fixed offshore oil and gas platform complex using individual risk per annum (IRPA) and potential loss of life (PLL) analyses. Findings reveal that applying the standard hazard and effects management process (HEMP) and as low as reasonably practicable (ALARP) guidelines and tools alone are insufficient. The application of practical lessons learned from the past oil and gas disasters using IRPA and PLL parameters has helped this research to produce an optimized QRA. The optimized QRA process is a live process which could be further improved with future lessons learned.

In response to interest and concerns about the effect which oil industry development would have in the province of Newfoundland, a number of studies were initiated, including attempts to assess the impacts on rural residents. An analysis of the offshore labour force indicated that Newfoundland residents represented 60% of the offshore force; however, their participation was predominantly in the junior drilling, junior marine and junior service positions. The provincial workers differed from the non-resident workers on a number of factors. Also of interest, the 35% of the Newfoundland workers interviewed had come from water transport occupations and were attracted by the perceived advantages of work in the oil industry, while the 34% who had come from the fishing industry, cited financial insecurity and poor working conditions of the fishery as their reasons for changing jobs.

Offshore Oil

A proposal to undertake exploration in the coastal waters adjacent to Sydney/Newcastle/Wollongong has brought strong protests on environmental grounds. This opposition is committed and the basis for it should be considered in the wider context of offshore exploration around Australia. Of the various activities involved in oil and gas exploration the potential impacts of marine seismic surveys and the likelihood of a blowout- related oil spill are those of greatest concern to the media and public.A review of the available literature shows the environmental effects of seismic surveys to be of little consequence provided non- explosive energy sources are used. The effects of an oil spill are heavily dependent on site conditions and the type of oil spilled.The literature shows that direct exposure to spilled oil is fatal to many marine species. However, the potential lethal effects are largely dependent on direct exposure and this declines with the weathering and degradation of the spill. Moreover, the risks of an oil spill occurring as a result of current transportation and handling of oil in coastal waters and points around Australia are much greater than would be presented by drilling an exploratory well.In considering the role of exploration as an assessment procedure rather than a land use it is possible to draw parallels between the conservation status of Australian coastal waters today and the onshore situation some 20 years ago. The offshore oil and gas exploration industry needs to take several measures if it is to avoid denial of access for exploration. These include clearly identifying the environmental effects of exploration as opposed to production, adopting industry- wide codes for environmental practice, and recording and disseminating the industry's environmental performance.

Significance The bids came from Greece’s Energean, an existing investor, and a consortium of Indian firms; there was little wider international interest. Neighbouring Lebanon’s first offshore oil and gas exploration round, which closed on October 12, was similarly disappointing, with just two bids received from one consortium consisting of France’s Total, Italy’s Eni and Russia’s Novatek. Impacts Political uncertainties following the resignation of Lebanese Prime Minister Saad al-Hariri could slow hydrocarbons exploration. The Lebanese government will be under domestic political pressure from NGOs to ensure transparency in its award of exploration licences. Israel will launch further bid rounds for the remaining blocks, but these are unlikely to produce a different result.
