The Impact

ABSTRACT Oil spills in coastal waters sometimes give rise to concerns that oil may become entrained in the seawater intakes of power stations, desalination units, and other industrial plants. This paper reviews the findings of an investigation, undertaken by the International Tanker Owners Pollution Federation and Sir M. MacDonald & Partners, on the effects of oil pollution on water-cooled electricity-generating stations and desalination plants using multistage flash distillation and reverse osmosis. The various components that could be contaminated by oil are described and, using case studies wherever possible, the effects on equipment, heat transfer surfaces, and potable water are discussed. Finally considered are various methods of minimizing the impact of oil and financial implications of oil contamination for the different types of industrial plant.

Big Data and Data Analytics have in recent times become important areas of focus in academia, in business and in society. This paper utilises experiments involving data visualisation of oil pollution studies and their effects on environment for enhanced learning in engineering education. Tracking and analysis of images and the use of accessible applications for the analysis of acquired data revealed the level of impact of the different types of oil pollution on grass vegetation. In accounting for these changes the primary RGB colours and corresponding values are used. The use of spectral analysis applications available in spectroscopy and comparison of results would in future prove useful in assessing some aspects of these changes in relation to wavelength and colours changes. The results of these studies would contribute in no small measure to the determination of best cleaning strategies for oil spills.

Oil spills are adverse events that may be very harmful to ecosystems and food chain. In particular, large sea oil spills are very dramatic occurrence often affecting sea and coastal areas. Therefore the sustainability of oil rig infrastructures and oil transportation via oil tankers are linked to law enforcement based on proper monitoring techniques which are also fundamental to mitigate the impact of such pollution. Within this context, in this study a meaningful showcase is analyzed using remotely sensed measurements collected by the Synthetic Aperture Radar (SAR) operated by the COSMO-SkyMed (CSK) constellation. The showcase presented refers to the Deepwater Horizon (DWH) oil incident that occurred in the Gulf of Mexico in 2010. It is one of the world's largest incidental oil pollution event that affected a sea area larger than 10,000 km2. In this study we exploit, for the first time, dual co-polarization SAR data collected by the Italian CSK X-band SAR constellation showing the key benefits of HH-VV SAR measurements in observing such a huge oil pollution event, especially in terms of the very dense revisit time offered by the CSK constellation.

AbstractThe development of safe desalination plants with low environmental impact is as important an issue as the supply of drinking water. The desalination plant in Jeddah (Saudi Arabia, Red Sea coast) produces freshwater from seawater by multi-stage flash distillation (MSFD) and reverse osmosis (RO). The process produces brine as by-product, which is dumped into the sea. The aim of this study was to assess the impact of Jeddah desalination plant on the coastal water in the nearby of the plant. Total concentrations of dissolved Cu, Ni, Zn and nutrients in several locations around the plant were analyzed by cathodic stripping voltammetry. The average levels of dissolved Cu, Ni, and Zn on surface in the sampling locations were 15.02, 11.02, and 68.03 nM respectively, whereas the levels at the seafloor near the discharging point were much higher. Distribution of temperature, salinity, nutrients and dissolved oxygen were quite normal both on surface and in depth.

ABSTRACT In the years following the passage of the Oil Pollution Act of 1990 (OPA 90), government agencies and regulated parties in the United States have begun to implement spill prevention and preparedness programs. For this analysis, 7 years of oil spill data collected in the Emergency Response Notification System were used to measure the impact that OPA 90 has had on preventing large spills. Furthermore, relationships among the types, sources, and location of spilled oil are characterized. A comparison of the number of reported 10,000-gallon oil spills for the years 1992-1995 to that number for the years 1989-1991 indicates a decline, not only for vessels but also for pipelines and fixed facilities. The decline in large oil spills to water from various sources appears to indicate that the efforts of government and industry have had a measurable impact on environmental protection.

Although, operationally, SAR sea oil slick observation is typically accomplished using C-band VV-polarized SAR imagery, during the DWH oil incident, because of their very dense revisit time, even single-polarization X-band COSMO-SkyMed (CSK) SAR measurements were collected. In this study, we exploit, for the first time, incoherent dual co-polarization SAR data collected by the Italian CSK X-band SAR constellation showing the key benefits of HH-VV SAR measurements in observing such a huge oil pollution event, especially in terms of the very dense revisit time offered by the CSK constellation.

Recent gas discoveries in the eastern Mediterranean Sea have led to multiple operations with substantial economic interest, and they are accompanied by the risk of oil spills and their potential environmental impacts. In this this study we compute the probability of an area being polluted by oil. The first stage of this computation is to determine what the likely scenarios for oil spills are, where the areas of higher oil spill probability are and what the expected size of the spill is. This study was performed as part of the RAOP-MED project, which considered ship collision scenarios, other accidental spill from ships and rigs, and accidents that might occur during fueling operations. The results of the project include a map of oil spill probability for the eastern Mediterranean that details different scenarios, as well as a map of the maximal spill size. We use these results to create possible oil spill scenarios and run Monte-Carlo simulations of the oil spill’s fate. The simulations use the MEDSLIK oil spill propagation model, forced by the realistic atmospheric and oceanic conditions that exist off the Israeli coast, as outlined by the SKIRON and SELIPS numerical models. Potential risk sources in the area are the ship traffic that enters and leaves the Suez channel, as well as the offshore platforms on the Nile Delta and in the Israeli exclusive economic zone. We also examine the impact of the alongshore current on the probability and severity of the pollution.

Abstract Oil is a major pollutant of the environment, and terrestrial oil spills frequently occur in desert areas. Although arthropods account for a large share of animal diversity, the effect of oil pollution on this group is rarely documented. We evaluated the effects of oil pollution on parasitoid wasps associated with Vachellia (formerly Acacia) tortilis (Forssk.) and Vachellia raddiana (Savi) trees in a hyper-arid desert that was affected by two major oil spills (in 1975 and 2014). We sampled the parasitoid populations between 2016 and 2018 in three sampling sites and compared their abundance, diversity, and community composition between oil-polluted and unpolluted trees. Parasitoid abundance in oil-polluted trees was lower in one of the sites affected by the recent oil spill, but not in the site affected by the 1975 oil spill. Oil-polluted trees supported lower parasitoid diversity than unpolluted trees in some sampling site/year combinations; however, such negative effects were inconsistent and pollution explained a small proportion of the variation in parasitoid community composition. Our results indicate that oil pollution may negatively affect parasitoid abundances and diversity, although the magnitude of the effect depends on the tree species, sampling site, and the time since the oil spill.

ABSTRACT The most important objectives of the International Maritime Organization (IMO) have been improving maritime safety and preventing marine pollution. The Marine Environment Protection Committee (MEPC), which is responsible for coordinating IMO's activities in preventing and controlling marine pollution from ships, agreed that spills of 100 tons of oil or more should be regarded as “significant.”1 Analyses of significant oil spills (more than 100 metric tons) from ships have helped develop spill statistics, categories of spill incidents, geographical data on spills, and so on. Analyses for the past 10 years show that about 75 percent of the incidents were caused by grounding, collision, and breakdown; about 8 percent were caused by operational errors while loading, discharging, or washing tanks; and about 17 percent were due to rough weather, fire, and other causes. These analyses suggest that measures can be taken to prevent oil pollution from ships chiefly by improving safety standards for ship construction, equipment, and operation. This paper analyzes several incidents to understand the causes, actions taken, and results of oil spills in different circumstances and with different types of oil. It also examines IMO's achievements in combating oil pollution and the difficulties that have been met in implementing Annex I of the Regulations for the Prevention of Pollution by Oil, the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 (MARPOL 73/78).
